Abstract: Extracellular heat shock protein-90alpha (eHsp90α) plays an essential role in tumour invasion and metastasis. The plasma eHsp90α levels in patients with various cancers correlate with the stages of the diseases. Nonetheless, the mechanism of action by tumour-secreted eHsp90α remained unclear. Here we show that eHsp90α accounts for approximately 1% of the total cellular Hsp90α and is associated with tumour-secreted exosomes. CRISPR-cas9 knockout of Hsp90α did not affect the overall distribution and quantity of secreted exosomes, but it caused increased exosome-associated CD9 and decreased exosome-associated TSG101, Alix, and CD63. However, Hsp90α-knockout tumour cells have not only lost their own constitutive motility, but also the ability to recruit stromal cells via secreted exosomes. These defects are specifically due to the lack of eHsp90α on tumour cell-secreted exosomes. Anti-Hsp90α antibody nullified the pro-motility activity of tumour-secreted exosomes and human recombinant Hsp90α protein fully rescued the functional defects of eHsp90α-free exosomes. Finally, while current exosome biogenesis models exclusively implicate the luminal location of host cytosolic proteins inside secreted exosomes, we provide evidence for eHsp90α location on the external surface of tumour-secreted exosomes. Taken together, this study elucidates a new mechanism of action by exosome-associated eHsp90α.

Abstract: Autophagy and interferon (IFN)-mediated innate immunity are critical antiviral defence mechanisms, and recent evidence indicated that tripartite motif (TRIM) proteins are important regulators of both processes. Although the role of TRIM proteins in modulating antiviral cytokine responses has been well established, much less is known about their involvement in autophagy in response to different viral pathogens. Through a targeted RNAi screen examining the relevance of selected TRIM proteins in autophagy induced by herpes simplex virus 1 (HSV-1), encephalomyocarditis virus (EMCV) and influenza A virus (IAV), we identified several TRIM proteins that regulate autophagy in a virus-species-specific manner, as well as a few TRIM proteins that were essential for autophagy triggered by all three viruses and rapamycin, among them TRIM23. TRIM23 was critical for autophagy-mediated restriction of multiple viruses, and this activity was dependent on both its RING E3 ligase and ADP-ribosylation factor (ARF) GTPase activity. Mechanistic studies revealed that unconventional K27-linked auto-ubiquitination of the ARF domain is essential for the GTP hydrolysis activity of TRIM23 and activation of TANK-binding kinase 1 (TBK1) by facilitating its dimerization and ability to phosphorylate the selective autophagy receptor p62. Our work identifies the TRIM23-TBK1-p62 axis as a key component of selective autophagy and further reveals a role for K27-linked ubiquitination in GTPase-dependent TBK1 activation.

Abstract: Macroautophagy/autophagy deregulation has been observed in perpetuated inflammation and the proliferation of tumor cells. However, the mechanisms underlying these changes have yet to be well-identified. UVRAG is one of the key players of autophagy, but its role in vivo remained puzzling. Our recent study utilized a mouse model with inducible expression of a cancer-derived frameshift (FS) mutation in UVRAG that dominant-negatively inhibits wild-type UVRAG, resulting in impaired stimulus-induced autophagy. The systemically compromised autophagy, particularly mitophagy, notably increases inflammation and associated pathologies. Furthermore, our discovery indicates that time-dependent autophagy suppression and ensuing CTNNB1/β-catenin activation may serve as one tumor-promoting mechanism underpinning age-related cancer susceptibility.

Abstract: Macroautophagy/autophagy is an auto-digestive pro-survival pathway activated in response to stress to target cargo for lysosomal degradation. In recent years, autophagy has become prominent as an innate antiviral defense mechanism through multiple processes, such as targeting virions and viral components for elimination. These exciting findings have encouraged studies on the ability of autophagy to restrict HIV. However, the role of autophagy in HIV infection remains unclear. Whereas some reports indicate that autophagy is detrimental for HIV, others have claimed that HIV deliberately activates this pathway to increase its infectivity. Moreover, these contrasting findings seem to depend on the cell type investigated. Here, we show that autophagy poses a hurdle for HIV replication, significantly reducing virion production. However, HIV-1 uses its accessory protein Nef to counteract this restriction. Previous studies have indicated that Nef affects autophagy maturation by preventing the fusion between autophagosomes and lysosomes. Here, we uncover that Nef additionally blocks autophagy initiation by enhancing the association between BECN1 and its inhibitor BCL2, and this activity depends on the cellular E3 ligase PRKN. Remarkably, the ability of Nef to counteract the autophagy block is more frequently observed in pandemic HIV-1 and its simian precursor SIVcpz infecting chimpanzees than in HIV-2 and its precursor SIVsmm infecting sooty mangabeys. In summary, our findings demonstrate that HIV-1 is susceptible to autophagy restriction and define Nef as the primary autophagy antagonist of this antiviral process.

Abstract: How lysosome and MTORC1 signaling interact remains elusive in terminally differentiated cells. A G4C2 repeat expansion in C9orf72 is the most common cause of familial amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) (C9ALS-FTD). We previously identified a C9orf72-SMCR8-containing complex. Here we found that c9orf72 and smcr8 double-knockout (dKO) mice exhibit similar but more severe immune defects than the individual knockouts. In c9orf72 or smcr8 mutant macrophages, lysosomal degradation and exocytosis were impaired due to the disruption of autolysosome acidification. As a result of impaired lysosomal degradation, MTOR protein was aberrantly increased, resulting in MTORC1 signaling overactivation. Inhibition of hyperactive MTORC1 partially rescued macrophage dysfunction, splenomegaly and lymphadenopathy in c9orf72 or smcr8 mutant mice. Pharmacological inhibition of lysosomal degradation upregulated MTOR protein and MTORC1 signaling in differentiated wild-type macrophages, which resemble phenotypes in KO mice. In contrast, C9orf72 or Smcr8 depletion in proliferating macrophages decreased MTORC1 signaling. Our studies causatively link C9orf72-SMCR8’s cellular functions in lysosomal degradation, exocytosis, and MTORC1 signaling with their organism-level immune regulation, suggesting cell state (proliferation vs. differentiation)-dependent regulation of MTOR signaling via lysosomes.Abbreviations: ALS: amyotrophic lateral sclerosis; ATG13: autophagy related 13; BMDMs: bone marrow-derived macrophages; BafA(1): bafilomycin A(1); C9orf72: C9orf72, member of C9orf72-SMCR8 complex; CD68: CD68 antigen; ConA: concanamycin A; dKO: double knockout; DENN: differentially expressed in normal and neoplastic cells; FTD: frontotemporal dementia; GEF: guanine nucleotide exchange factor; IFNB1: interferon beta 1, fibroblast; IFNG: interferon gamma; IL1B/IL-1β: interleukin 1 beta; IL6: interleukin 6; iPSCs: induced pluripotent stem cells; LAMP1: lysosomal-associated membrane protein 1; LPOs: LAMP1-positive organelles; MAP1LC3/LC3: microtubule-associated protein 1 light chain 3; LPS: lipopolysaccharide; MTORC1: mechanistic target of rapamycin kinase complex 1; MEFs: mouse embryonic fibroblasts; MNs: motor neurons; NOS2/iNOS: nitric oxide synthase 2, inducible; RAN: repeat-associated non-AUG; RB1CC1/FIP200: RB1-inducible coiled-coil 1; RPS6/S6: ribosomal protein S6; RPS6KB1/S6K1: ribosomal protein S6 kinase, polypeptide 1; SMCR8: Smith-Magenis syndrome chromosome region, candidate 8; SQSTM1/p62: sequestosome 1; TFEB: transcription factor EB; TNF: tumor necrosis factor; TSC1: TSC complex subunit 1; ULK1: unc-51 like kinase 1; v-ATPase: vacuolar-type H⁺-translocating ATPase

Abstract: Significance Skin pigmentation provides first-line protection against UV radiation (UVR) that increases the risk of skin cancers. However, mechanisms underlying this process remain poorly understood. Here, we identified the autophagic tumor suppressor UVRAG as a bona fide player in melanosome biogenesis by targeting biogenesis of lysosome-related organelles complex 1 (BLOC-1) independently of autophagy. UVRAG maintains the localization and stability of BLOC-1 to facilitate the sorting/delivery of melanogenic cargoes. Reduced levels of UVRAG rendered cells unresponsive to UVR–α-MSH–MITF signaling and defective melanocyte development in vivo. Moreover, UVRAG-mediated melanogenesis and tanning response were impaired in oncogene-driven melanoma. This study represents a description of a noncanonical role of autophagy factor in melanogenic remodeling and also provides mechanistic insights into UVRAG in pigmentation disorder and UV-associated cancer.

Abstract: Although alterations of the macroautophagy/autophagy-lysosome pathway have been observed in cancer for many years, the mechanisms underlying these changes and the importance of autophagic and lysosomal reprogramming by cancer have yet to be well identified. Our recent study demonstrates that oncogenic BRAF signaling promotes melanoma growth and resistance to BRAF-targeted therapy through phosphorylation and functional inactivation of TFEB (transcription factor EB) and consequent suppression of the autophagy-lysosome gene network. This is by no means the first time that this pathway has been directly linked to oncogenic BRAF-driven melanoma. The key observations revealed in this study also leads to a complex but growing convergence of our understanding of the biology of the autophagy-lysosome pathway and the mechanisms underlying cancer prevention and treatment.

Abstract: More than 50% of the U.S. population is infected with herpes simplex virus type-I (HSV-1) and global infectious estimates are nearly 90%. HSV-1 is normally seen as a harmless virus but debilitating diseases can arise, including encephalitis and ocular diseases. HSV-1 is unique in that it can undermine host defenses and establish lifelong infection in neurons. Viral reactivation from latency may allow HSV-1 to lay siege to the brain (Herpes encephalitis). Recent advances maintain that HSV-1 proteins act to suppress and/or control the lysosome-dependent degradation pathway of macroautophagy (hereafter autophagy) and consequently, in neurons, may be coupled with the advancement of HSV-1-associated pathogenesis. Furthermore, increasing evidence suggests that HSV-1 infection may constitute a gradual risk factor for neurodegenerative disorders. The relationship between HSV-1 infection and autophagy manipulation combined with neuropathogenesis may be intimately intertwined demanding further investigation.

Abstract: The viral Bcl-2 homolog (vBcl2) of Kaposi's sarcoma-associated herpesvirus (KSHV) displays efficient antiapoptotic and antiautophagic activity through its central BH3 domain, which functions to prolong the life span of virus-infected cells and ultimately enhances virus replication and latency. Independent of its antiapoptotic and antiautophagic activity, vBcl2 also plays an essential role in KSHV lytic replication through its amino-terminal amino acids (aa) 11 to 20. Here, we report a novel molecular mechanism of vBcl2-mediated regulation of KSHV lytic replication. vBcl2 specifically bound the tegument protein open reading frame 55 (ORF55) through its amino-terminal aa 11 to 20, allowing their association with virions. Consequently, the vBcl2 peptide derived from vBcl2 aa 11 to 20 effectively disrupted the interaction between vBcl2 and ORF55, inhibiting the incorporation of the ORF55 tegument protein into virions. This study provides new insight into vBcl2's function in KSHV virion assembly that is separable from its inhibitory role in host apoptosis and autophagy. IMPORTANCE KSHV, an important human pathogen accounting for a large percentage of virally caused cancers worldwide, has evolved a variety of stratagems for evading host immune responses to establish lifelong persistent infection. Upon viral infection, infected cells can go through programmed cell death, including apoptosis and autophagy, which plays an effective role in antiviral responses. To counter the host response, KSHV vBcl2 efficiently blocks apoptosis and autophagy to persist for the life span of virus-infected cells. Besides its anti-programmed-cell-death activity, vBcl2 also interacts with the ORF55 tegument protein for virion assembly in infected cells. Interestingly, the vBcl2 peptide disrupts the vBcl2-ORF55 interaction and effectively inhibits KSHV virion assembly. This study indicates that KSHV vBcl2 harbors at least three genetically separable functions to modulate both host cell death signaling and virion production and that the vBcl2 peptide can be developed as an anti-KSHV therapeutic application.

Abstract: Secreted exosomes carrying lipids, proteins, and nucleic acids conduct cell-cell communications within the microenvironment of both physiological and pathological conditions. Exosome secretion is triggered by extracellular or intracellular stress signals. Little is known, however, about the signal transduction between stress cues and exosome secretion. To identify the linker protein, we took advantage of a unique finding in human keratinocytes. In these cells, although transforming growth factor alpha (TGF-α) and epidermal growth factor (EGF) share the same EGF receptor and previously indistinguishable intracellular signaling networks, only TGF-α stimulation causes exosome-mediated secretion. However, deduction of EGF-activated pathways from TGFα-activated pathways in the same cells allowed us to identify the proline-rich Akt substrate of 40 kDa (PRAS40) as the unique downstream effector of TGF-α but not EGF signaling via threonine 308-phosphorylated Akt. PRAS40 knockdown (KD) or PRAS40 dominant-negative (DN) mutant overexpression blocks not only TGF-α- but also hypoxia- and H2O2-induced exosome secretion in a variety of normal and tumor cells. Site-directed mutagenesis and gene rescue studies show that Akt-mediated activation of PRAS40 via threonine 246 phosphorylation is both necessary and sufficient to cause exosome secretion without affecting the endoplasmic reticulum/Golgi pathway. Identification of PRAS40 as a linker protein paves the way for understanding how stress regulates exosome secretion under pathophysiological conditions.

Abstract: Ultraviolet radiation (UVR)-induced skin pigmentation, afforded by the dark organelles termed melanosomes, accounts for the first-line protection against environmental UVR that increases the risk of developing skin cancers including melanoma. We have recently discovered that UVRAG, originally identified as a BECN1-binding macroautophagy/autophagy protein, appears to have a specialized function in melanosome biogenesis beyond autophagy through its interaction with the biogenesis of lysosome-related organelles complex 1 (BLOC-1). This melanogenic function of UVRAG is controlled by the melanocyte-specific transcription factor MITF as a downstream effector of the α-melanocyte-stimulating hormone (α-MSH)-cAMP signaling in the suntan response, which is compromised in BRAF mutant melanoma. Thus we propose a new mode of UVRAG activity and regulation in melanocyte biology that may affect melanoma predisposition.

Abstract: Mitochondrial antiviral signaling (MAVS) protein has an important role in antiviral immunity and autoimmunity. However, the pathophysiological role of this signaling pathway, especially in the brain, remains elusive. Here we demonstrated that MAVS signaling existed and mediated poly(I:C)-induced inflammation in the brain. Along with the MAVS signaling activation, there was an induction of autophagic activation. Autophagy negatively regulated the activity of MAVS through direct binding of LC3 to the LIR motif Y(9)xxI(12) of MAVS. We also found that c-Abl kinase phosphorylated MAVS and regulated its interaction with LC3. Interestingly, tyrosine phosphorylation of MAVS was required for downstream signaling activation. Importantly, in vivo data showed that the deficiency of MAVS or c-Abl prevented MPTP-induced microglial activation and dopaminergic neuron loss. Together, our findings reveal the molecular mechanisms underlying the regulation of MAVS-dependent microglial activation in the nervous system, thus providing a potential target for the treatment of microglia-driven inflammatory brain diseases.

Abstract: Heterotaxy characterized by abnormal left–right body asymmetry causes diverse congenital anomalies. Organ rotation is a crucial developmental process to establish the left–right patterning during animal development. However, the molecular basis of how organ rotation is regulated is poorly understood. Here we report that Drosophila UV-resistance associated gene (UVRAG), a tumor suppressor that regulates autophagy and endocytosis, plays unexpected roles in controlling organ rotation. Loss-of-function mutants of UVRAG show seriously impaired organ rotation phenotypes, which are associated with defects in endocytic trafficking rather than autophagy. Blunted endocytic degradation by UVRAG deficiency causes endosomal accumulation of Notch, resulting in abnormally enhanced Notch activity. Knockdown of Notch itself or expression of a dominant negative form of Notch transcriptional co-activator Mastermind is sufficient to rescue the rotation defect in UVRAG mutants. Consistently, UVRAG-mutated heterotaxy patient cells also display highly increased Notch protein levels. These results suggest evolutionarily conserved roles of UVRAG in organ rotation by regulating Notch endocytic degradation.

15. Abstract 1984: Cell fate reprogramming of liver tumor-initiating stem-like cells via phosphorylated NUMB and TBC1D15

Abstract: Tumor-initiating stem-like cells (TICs) are defective in their control of asymmetric division. Stem cells are maintained through asymmetric self-renewing divisions in which one daughter cell commits to a specific fate while the other retains the multipotent characteristics of its parent. The p53 interacting protein NUMB preserves this intrinsic cellular asymmetry and functions as a vital barrier against unchecked expansion as seen in TICs. How TICs overcome this control of asymmetric division to cause cancer is unknown. The hypothesis is that accentuated TLR4-NANOG-mediated NUMB phosphorylation and TBC1D15 upregulation promote self-renewal of TICs in liver oncogenesis caused by HCV and alcohol. Here, we determined the causal roles of NUMB phosphorylation and TBC1D15 oncoprotein in alcohol-induced liver tumorigenesis in HCV-Tg mice. Liver-specific TBC1D15 deficiency or non-phosphorylatable mutations of NUMB, reduce liver tumor incidence and tumor-associated NANOG+ TICs in HCV NS5A Tg mice fed alcohol Western diet. TICs lost asymmetric division capacity and overexpressed TBC1D15, which associated with NUMB to promote aPKCζ activity and NUMB phosphorylation. Thus, TIC self-renewal is dependent on TBC1D15 and NUMB phosphorylation. Similarly, aPKCζ-mediated NUMB phosphorylation and induced TBC1D15 are mutually required for self-renewal. Furthermore, TBC1D15 activated NOTCH via binding to NOTCH intracellular domain to trigger its proteolytic. TBC1D15 interacts with all NOTCH isoforms, activates NOTCH pathway, and induces Nanog and TIC self-renewal in a NOTCH-dependent manner. TBC1D15 cooperates with the NOTCH pathway to support TIC tumorigenic activity and an inhibitor of this interaction is potentially therapeutic. Candidate small molecule antagonists have been tested for their ability to block the interaction of TBC1D15-NOTCH/NICD. The originality of this findings lies within the discovery of the novel oncoprotein TBC1D15 and its unique oncogenic activities involving p53 degradation and cooperation with the NOTCH pathway in TICs and CD133+ Huh7 cells.

Abstract: The critical role of the cellular autophagy pathway in viral infection and pathogenesis has become increasingly apparent. Mounting evidences suggest that viruses have developed different strategies to meticulously modulate intracellular autophagy for their own benefits, thereby either promoting efficient viral replication or facilitating viral persistence. While our understanding of these strategies is still in its incipient stage, recent advances demonstrate that gamma herpesvirus Bcl-2 homolog (vBcl-2), which protects virus-infected cells from apoptosis, also suppresses cellular autophagy pathway through its direct interaction with the autophagy protein Beclin1. Interestingly, vBcl-2 has evolved to harbor the enhanced anti-autophagic activity compared to its host counterpart, suggesting an important role of cellular autophagy in response to viral infection and virus-associated pathogenesis. Thus, a detailed study of vBcl-2-mediated regulation of autophagy signal transduction pathway may lead to a better understanding of not only how virus escapes from host innate immunity but also how autophagy regulates viral infection and environmental stresses.

Abstract: Ultraviolet (UV)-induced DNA damage, a major risk factor for skin cancers, is primarily repaired by nucleotide excision repair (NER). UV-radiation Resistance Associated Gene (UVRAG) is a tumor suppressor involved in autophagy. It was initially isolated as a cDNA partially complementing UV sensitivity in Xeroderma Pigmentosum (XP), but this was not explored further. Here we show that UVRAG plays an integral role in UV-induced DNA damage repair. It localizes to photolesions and associates with DDB1 to promote the assembly and activity of the DDB2-DDB1-Cul4A–Roc1 (CRL4DDB2) ubiquitin-ligase complex, leading to efficient XPC recruitment and global-genomic NER. UVRAG depletion decreased substrate handover to XPC and conferred UV-damage hypersensitivity. We confirmed the importance of UVRAG for UV-damage tolerance using a Drosophila model. Furthermore, increased UV-signature mutations in melanoma correlate with reduced expression of UVRAG. Our results identify UVRAG as a regulator of CRL4DDB2-mediated NER and suggest that its expression levels may influence melanoma predisposition.

19. Frameshift mutation of UVRAG: Switching a tumor suppressor to an oncogene in colorectal cancer

Abstract: Colorectal cancer (CRC) ranks as the second leading cause of cancer-related deaths in the Western world. It has a nearly 50% metastasis rate and only a subset of patients respond to current treatment strategy. UVRAG, a key autophagy effector and a guardian of chromosomal stability, is truncated by a frameshift (FS) mutation in CRC with microsatellite instability (MSI). However, the pathological and clinical significance of this UVRAG truncation remains less understood. Our recent study discovered that this FS mutation yields a much shortened form of the UVRAG protein, which counteracts most of the tumor-suppressor functions of wild-type (WT) UVRAG in autophagy, centrosome stability, and DNA repair in a dominant-negative fashion. Whereas this truncated mutation of UVRAG promotes tumorigenesis, epithelial-to-mesenchymal transition, and metastasis, it appears to sensitize CRC tumors to adjuvant chemotherapy, making it a potential molecular marker to individualize therapeutic approach in CRC.

Abstract: Autophagy, the degradation of cytoplasmic components, is an evolutionarily conserved homeostatic process involved in environmental adaptation, lifespan determination and tumour development. The tumor suppressor Beclin1 is part of the PI(3) kinase class III (PI(3)KC3) lipid-kinase complex that induces autophagy. The autophagic activity of the Beclin1-PI(3)KC3 complex, however, is suppressed by Bcl-2. Here, we report the identification of a novel coiled-coil UV irradiation resistance-associated gene (UVRAG) as a positive regulator of the Beclin1-PI(3)KC3 complex. UVRAG, a tumour suppressor candidate that is monoallelically mutated at high frequency in human colon cancers, associates with the Beclin1-Bcl-2-PI(3)KC3 multiprotein complex, where UVRAG and Beclin1 interdependently induce autophagy. UVRAG-mediated activation of the Beclin1-PI(3)KC3 complex promotes autophagy and also suppresses the proliferation and tumorigenicity of human colon cancer cells. These results identify UVRAG as an essential component of the Beclin1-PI(3)KC3 lipid kinase complex that is an important signalling checkpoint for autophagy and tumour-cell growth.

Abstract: Ultraviolet (UV)-induced DNA damage is a major risk factor for skin cancers including melanoma. UVRAG, originally identified to complement UV sensitivity in xeroderma pigmentosum (XP), has since been implicated in modulating macroautophagy/autophagy, in coordinating different intracellular trafficking pathways, and in maintaining chromosomal stability. Intriguingly, our recent study has demonstrated that UVRAG plays an essential role in protecting cells from UV-induced DNA damage by activating the nucleotide excision repair (NER) pathway. Since NER is the major mechanism by which cells maintain DNA integrity against UV insult, the inactivation of UVRAG seen in some melanoma may impart these cells with an ability to accumulate high-load UV mutagenesis, leading to cancer progression. Thus, this property of UVRAG has untapped potential to be of fundamental importance in understanding the genetics and pathogenesis of human skin cancer.

Abstract: Cellular apoptosis is of major importance in the struggle between virus and host. Although many viruses use various strategies to control the cell death machinery by encoding anti-apoptotic virulence factors, it is now becoming clear that, in addition to their role in inhibiting apoptosis, these factors function in multiple immune and metabolic pathways to promote fitness and pathogenesis. In this Progress article, we discuss novel functions of viral anti-apoptotic factors in the regulation of autophagy, in the nuclear factor-κB (NF-κB) pathway and in interferon signalling, with a focus on persistent and oncogenic gammaherpesviruses. If viral anti-apoptotic proteins are to be properly exploited as targets for antiviral drugs, their diverse and complex roles should be considered.

Abstract: RIG-I is a pattern recognition receptor that senses viral RNA and is crucial for host innate immune defense. Here, we describe a mechanism of RIG-I activation through amidotransferase-mediated deamidation. We show that viral homologs of phosphoribosylformylglycinamidine synthetase (PFAS), although lacking intrinsic enzyme activity, recruit cellular PFAS to deamidate and activate RIG-I. Accordingly, depletion and biochemical inhibition of PFAS impair RIG-I deamidation and concomitant activation. Purified PFAS and viral homolog thereof deamidate RIG-I in vitro. Ultimately, herpesvirus hijacks activated RIG-I to avoid antiviral cytokine production; loss of RIG-I or inhibition of RIG-I deamidation results in elevated cytokine production. Together, these findings demonstrate a surprising mechanism of RIG-I activation that is mediated by an enzyme.

Abstract: While the cell imposes multiple barriers to virus entry, enveloped viruses are remarkably still able to gain entry to their cellular hosts by hitchhiking and remodeling the endomembrane system to traffic within, and eventually escape from, endosomal organelles for their genome release. Elucidating viral entry mechanisms and their interaction with the host trafficking network is necessary for antiviral therapy. Here, we focus on the use of host autophagy molecular factors during the entry of prototypic negative-stranded RNA viruses, and highlight recent progress in our understanding of the role of one such factor, UVRAG, in both viral and cellular endocytic membrane trafficking and fusion events.

Abstract: Functional inactivation of UV irradiation resistance associated gene (UVRAG) is implicated in common human cancers. It was originally accepted that UVRAG functions as a promoter of the autophagy pathway by forming a stable complex with Beclin 1. However, recent studies have highlighted novel non-autophagic roles of UVRAG, and these reports indicate that UVRAG is much more versatile than we originally expected. In addition to regulating catabolic autophagy, UVRAG is involved in regulating endosomal membrane trafficking, repairing DNA lesions, patrolling the centrosome, and preventing apoptosis. These studies are beginning to shed light on the complexity and cross-talk between the signaling networks involving UVRAG, which normally control diverse cellular processes, and how disruption of these networks leads to tumor formation.

Abstract: Endoplasmic reticulum (ER)-Golgi membrane transport and autophagy are intersecting trafficking pathways that are tightly regulated and crucial for homeostasis, development and disease. Here, we identify UVRAG, a beclin-1-binding autophagic factor, as a phosphatidylinositol-3-phosphate (PtdIns(3)P)-binding protein that depends on PtdIns(3)P for its ER localization. We further show that UVRAG interacts with RINT-1, and acts as an integral component of the RINT-1-containing ER tethering complex, which couples phosphoinositide metabolism to COPI-vesicle tethering. Displacement or knockdown of UVRAG profoundly disrupted COPI cargo transfer to the ER and Golgi integrity. Intriguingly, autophagy caused the dissociation of UVRAG from the ER tether, which in turn worked in concert with the Bif-1-beclin-1-PI(3)KC3 complex to mobilize Atg9 translocation for autophagosome formation. These findings identify a regulatory mechanism that coordinates Golgi-ER retrograde and autophagy-related vesicular trafficking events through physical and functional interactions between UVRAG, phosphoinositide and their regulatory factors, thereby ensuring spatiotemporal fidelity of membrane trafficking and maintenance of organelle homeostasis.

Abstract: Here, we show that forced expression of a B-cell lymphoma 2 (bcl-2) protein lacking residues 1 to 36 at the N-terminal, including the entire Bcl-2 homology 4 (BH4) domain, determines reduction of in vitro and in vivo human melanoma growth. Noteworthy, melanoma cells in vivo exhibit markedly increased autophagy, as response to expression of bcl-2 protein deleted of its BH4 domain. This observation led to the identification of a novel gain of function for bcl-2 protein lacking the BH4 domain. In particular, upon different autophagic stimuli in vitro, overexpression of bcl-2 protein deleted of BH4 domain induces autophagosome accumulation, conversion of microtubule-associated protein 1 light chain 3B-II, reduced expression of p62/SQSTM1 protein, and thereby enhanced autophagic flux. The relevance of Beclin-1 is evidenced by the fact that 1) the autophagy-promoting and growth-inhibiting properties are partially rescued by Beclin-1 knockdown in cells expressing bcl-2 protein lacking the BH4 domain, 2) Beclin-1 only interacts with wild-type but not with deleted bcl-2, and 3) BH4 domain removal from bcl-2 protein does not influence in vitro and in vivo growth of tumor cells expressing low levels of endogenous Beclin-1. These results provide new insight into molecular mechanism of bcl-2 functions and represent a rationale for the development of agents interfering with the BH4 domain of bcl-2 protein.

Abstract: Autophagy is a highly regulated membrane remodeling process that allows the lysosome-mediated degradation of cytoplasmic entities by sequestrating them in double-membrane autophagosomes. Autophagy is hence highly intertwined with the endocytic trafficking pathway, sharing similar molecular machinery. Atg14L, also known as Beclin 1-associated autophagy-related key regulator (Barkor), directly interacts with Beclin 1 through its coiled-coil domain and enhances phosphatidylinositol 3-phosphate kinase class III (PI3KC3) activity to induce autophagosome membrane nucleation, highlighting its essential role in the early stage of mammalian autophagy. Here, we report a novel function of Atg14L in the endocytic trafficking pathway wherein Atg14L binds to and colocalizes with the fusogenic SNARE effector protein Snapin to facilitate endosome maturation. Atg14L specifically binds to Snapin and this interaction effectively facilitates endosomal maturation without affecting autophagic cargo degradation. Consequently, atg14l knockdown significantly delayed the late stage of endocytic trafficking, as evidenced by the retarded kinetics of internalized surface receptor degradation. This phenotype was effectively complemented by Atg14L wildtype or Beclin 1-binding mutant, but not by its Snapin-binding mutant. Taken together, our study demonstrates that Atg14L functions as a multivalent trafficking effector that regulates endosome maturation as well as autophagosome formation, reflecting the complexity of the crosstalk between autophagic and endocytic vesicle trafficking in higher eukaryotes.

Abstract: SummaryAutophagy defects have recently been associated with chromosomal instability, a hallmark of human cancer. However, the functional specificity and mechanism of action of autophagy-related factors in genome stability remain elusive. Here we report that UVRAG, an autophagic tumor suppressor, plays a dual role in chromosomal stability, surprisingly independent of autophagy. We establish that UVRAG promotes DNA double-strand-break repair by directly binding and activating DNA-PK in nonhomologous end joining. Disruption of UVRAG increases genetic instability and sensitivity of cells to irradiation. Furthermore, UVRAG was also found to be localized at centrosomes and physically associated with CEP63, an integral component of centrosomes. Disruption of the association of UVRAG with centrosomes causes centrosome instability and aneuploidy. UVRAG thus represents an autophagy-related molecular factor that also has a convergent role in patrolling both the structural integrity and proper segregation of chromosomes, which may confer autophagy-independent tumor suppressor activity.

Abstract: The anti-apoptotic Bcl-2 protein, which confers oncogenic transformation and drug resistance in most human cancers, including breast cancer, has recently been shown to effectively counteract autophagy by directly targeting Beclin1, an essential autophagy mediator and tumor suppressor. However, it remains unknown whether autophagy inhibition contributes to Bcl-2-mediated oncogenesis. Here, by using a loss-of-function mutagenesis study, we show that Bcl-2-mediated antagonism of autophagy has a critical role in enhancing the tumorigenic properties of MCF7 breast cancer cells independent of its anti-apoptosis activity. A Bcl-2 mutant defective in apoptosis inhibition but competent for autophagy suppression promotes MCF7 breast cancer cell growth in vitro and in vivo as efficiently as wild-type Bcl-2. The growth-promoting activity of this Bcl-2 mutant is strongly correlated with its suppression of Beclin1-dependent autophagy, leading to sustained p62 expression and increased DNA damage in xenograft tumors, which may directly contribute to tumorigenesis. Thus, the anti-autophagic property of Bcl-2 is a key feature of Bcl-2-mediated oncogenesis and may in some contexts, serve as an attractive target for breast and other cancer therapies.

Abstract: Autophagy is an evolutionarily conserved catabolic process that involves the invagination and degradation of cytoplasmic components through an autophagosomelysosome track. Autophagy functions as a quality control of cellular milieu and is implicated in a wide variety of pathological conditions. However, excessive or imbalanced autophagic flux may also be associated with cellular toxicity and may potentially contribute to the development of pathological conditions. Just as all membrane trafficking systems need to constantly strike a balance in their level of activation and inhibition to ensure proper spatial and temporal delivery of their cargo, autophagy must also be tightly regulated. Here, we provide an overview of the current knowledge regarding the negative regulation of mammalian autophagy in an effort to understand its physiological relevance and potential clinical importance.

Abstract: γ-herpesviruses (γHVs) have developed an interaction with their hosts wherein they establish a life-long persistent infection and are associated with the onset of various malignancies. One critical virulence factor involved in the persistency of murine γ-herpesvirus 68 (γHV68) is the viral homolog of the Bcl-2 protein (vBcl-2), which has been implicated to counteract both host apoptotic responses and autophagy pathway. However, the relative significance of the two activities of vBcl-2 in viral persistent infection has yet to be elucidated. Here, by characterizing a series of loss-of-function mutants of vBcl-2, we have distinguished the vBcl-2-mediated antagonism of autophagy from the vBcl-2-mediated inhibition of apoptosis in vitro and in vivo. A mutant γHV68 virus lacking the anti-autophagic activity of vBcl-2 demonstrates an impaired ability to maintain chronic infections in mice, whereas a mutant virus lacking the anti-apoptotic activity of vBcl-2 establishes chronic infections as efficiently as the wild-type virus but displays a compromised ability for ex vivo reactivation. Thus, the vBcl-2-mediated antagonism of host autophagy constitutes a novel mechanism by which γHVs confer persistent infections, further underscoring the importance of autophagy as a critical host determinant in the in vivo latency of γ-herpesviruses., Author Summary Autophagy (‘self-eating’, lysosome-dependent degradation and recycling of the intracellular components in response to stress) and apoptosis (‘self-killing’, cells commit suicide in response to stress) are important host defense mechanisms against viral infections. γ-herpesvirus 68 (γHV68) encodes a Bcl-2 family protein, vBcl-2, that effectively antagonizes both autophagy and apoptosis and is required for chronic viral infection and pathogenesis. However, the relative contributions of the vBcl-2-mediated evasion of autophagy and apoptosis to γHV68 persistent infection remain largely unknown. Here, we characterized a series of vBcl-2 mutants to genetically and functionally distinguish these closely related activities of vBcl-2 in vitro and in vivo. We have found that the inhibition of autophagy by vBcl-2 is important for maintaining latent infections, while the anti-apoptotic activity of vBcl-2 is largely involved in efficient viral reactivation from latency. Our findings thus reveal a novel paradigm for the vBcl-2-mediated evasion of autophagy and apoptosis during chronic viral infection, identifying a vital role for autophagy in controlling γHV68 latent infection.

Abstract: Upon viral infection, the major defensive strategy employed by the host immune system is the activation of the interferon (IFN)-mediated antiviral pathway, which is overseen by IFN regulatory factors (IRFs). In order to complete their life cycles, viruses must find a way to modulate the host IFN-mediated immune response. Kaposi's sarcoma-associated herpesvirus (KSHV), a human tumor-inducing herpesvirus, has developed a unique mechanism for antagonizing cellular IFN-mediated antiviral activity by incorporating viral homolog of the cellular IRFs, called vIRFs, into its genome. Here, we summarize the novel evasion mechanisms by which KSHV, through its vIRFs, circumvents IFN-mediated innate immune responses and deregulates the cell growth control mechanism.

Abstract: Autophagy is an active homeostatic degradation process for the removal or turnover of cytoplasmic components wherein the LC3 ubiquitin-like protein undergoes an Atg7 E1-like enzyme/Atg3 E2-like enzyme-mediated conjugation process to induce autophagosome biogenesis. Besides its cytoprotective role, autophagy acts on cell death when it is abnormally upregulated. Thus, the autophagy pathway requires tight regulation to ensure that this degradative process is well balanced. Two death effector domains (DED1/2) containing cellular FLICE-like inhibitor protein (cFLIP) and viral FLIP (vFLIP) of Kaposi's sarcoma-associated herpesvirus (KSHV), Herpesvirus saimiri (HVS), and Molluscum contagiosum virus (MCV) protect cells from apoptosis mediated by death receptors. Here, we report that cellular and viral FLIPs suppress autophagy by preventing Atg3 from binding and processing LC3. Consequently, FLIP expression effectively represses cell death with autophagy, as induced by rapamycin, an mTor inhibitor and an effective anti-tumour drug against KSHV-induced Kaposi's sarcoma (KS) and primary effusion lymphoma (PEL). Remarkably, either a DED1 alpha2-helix ten amino-acid (alpha2) peptide or a DED2 alpha4-helix twelve amino-acid (alpha4) peptide of FLIP is individually sufficient for binding FLIP itself and Atg3, with the peptide interactions effectively suppressing Atg3-FLIP interaction without affecting Atg3-LC3 interaction, resulting in robust cell death with autophagy. Our study thus identifies a checkpoint of the autophagy pathway where cellular and viral FLIPs limit the Atg3-mediated step of LC3 conjugation to regulate autophagosome biogenesis. Furthermore, the FLIP-derived short peptides induce growth suppression and cell death with autophagy, representing biologically active molecules for potential anti-cancer therapies.

Abstract: Autophagy is a lysosome-directed membrane trafficking event for the degradation of cytoplasmic components, including organelles. The past few years have seen a great advance in our understanding of the cellular machinery of autophagosome biogenesis, the hallmark of autophagy. However, our global understanding of autophagosome maturity remains relatively poor and fragmented. The topological similarity of autophagosome and endosome delivery to lysosomes suggests that autophagic and endosomal maturation may have evolved to share associated machinery to promote the lysosomal delivery of their cargoes. We have recently discovered that UVRAG, originally identified as a Beclin 1-binding autophagy protein, appears to be an important factor in autophagic and endosomal trafficking through its interaction with the class C Vps tethering complex. Given the ability of UVRAG to bind Beclin 1 and the class C Vps complex in a genetically and functionally separable manner, it may serve as an important regulator for the spatial and/or temporal control of diverse cellular trafficking events. As more non-autophagic functions of UVRAG are unveiled, our understanding of seemingly different cellular processes may move a step further.

Abstract: Autophagic and endocytic pathways are tightly regulated membrane rearrangement processes that are crucial for homeostasis, development and disease. Autophagic cargo is delivered from autophagosomes to lysosomes for degradation through a complex process that topologically resembles endosomal maturation. Here, we report that a Beclin1-binding autophagic tumour suppressor, UVRAG, interacts with the class C Vps complex, a key component of the endosomal fusion machinery. This interaction stimulates Rab7 GTPase activity and autophagosome fusion with late endosomes/lysosomes, thereby enhancing delivery and degradation of autophagic cargo. Furthermore, the UVRAG-class-C-Vps complex accelerates endosome–endosome fusion, resulting in rapid degradation of endocytic cargo. Remarkably, autophagosome/endosome maturation mediated by the UVRAG-class-C-Vps complex is genetically separable from UVRAG–Beclin1-mediated autophagosome formation. This result indicates that UVRAG functions as a multivalent trafficking effector that regulates not only two important steps of autophagy — autophagosome formation and maturation — but also endosomal fusion, which concomitantly promotes transport of autophagic and endocytic cargo to the degradative compartments.

Abstract: A multiprotein complex composed of Beclin 1, PI(3)KC3 and UVRAG promotes autophagosome formation, while this activity is suppressed by a cohort of antiapoptotic Bcl-2 family members. Recently, we showed that a viral Bcl-2 of murine gamma-herpesvirus 68, known as M11, binds to Beclin 1 with markedly high affinity in comparison with cellular Bcl-2 or Bcl-X(L) that interacts with Beclin 1 weakly.(1) Furthermore, the binding affinity directly correlated with the potency of inhibition of autophagosome formation in cells. Herein, we present additional data showing that Beclin 1 forms a large homo-oligomer, and this oligomerization is partly disrupted by the binding of M11. Oligomerized Beclin 1 is proposed to serve as a platform enabling a concerted action of many molecules of the associating proteins, including Bif-1 that could be directly involved in autophagosome biogenesis on membranes owing to its BAR domain.

Abstract: Autophagy is an evolutionarily conserved 'self-eating' process. Although the genes essential for autophagy (named Atg) have been identified in yeast, the molecular mechanism of how Atg proteins control autophagosome formation in mammalian cells remains to be elucidated. Here, we demonstrate that Bif-1 (also known as Endophilin B1) interacts with Beclin 1 through ultraviolet irradiation resistance-associated gene (UVRAG) and functions as a positive mediator of the class III PI(3) kinase (PI(3)KC3). In response to nutrient deprivation, Bif-1 localizes to autophagosomes where it colocalizes with Atg5, as well as microtubule-associated protein light chain 3 (LC3). Furthermore, loss of Bif-1 suppresses autophagosome formation. Although the SH3 domain of Bif-1 is sufficient for binding to UVRAG, both the BAR and SH3 domains are required for Bif-1 to activate PI(3)KC3 and induce autophagosome formation. We also observed that Bif-1 ablation prolongs cell survival under starvation conditions. Moreover, knockout of Bif-1 significantly enhances the development of spontaneous tumours in mice. These findings suggest that Bif-1 joins the UVRAG-Beclin 1 complex as a potential activator of autophagy and tumour suppressor.

Abstract: Activation of pattern recognition receptors and proper regulation of downstream signaling are crucial for host innate immune response. Upon infection, the NF-κB and interferon regulatory factors (IRF) are often simultaneously activated to defeat invading pathogens. Mechanisms concerning differential activation of NF-κB and IRF are not well understood. Here we report that a MAVS variant inhibits interferon (IFN) induction, while enabling NF-κB activation. Employing herpesviral proteins that selectively activate NF-κB signaling, we discovered that a MAVS variant of ~50 kDa, thus designated MAVS50, was produced from internal translation initiation. MAVS50 preferentially interacts with TRAF2 and TRAF6, and activates NF-κB. By contrast, MAVS50 inhibits the IRF activation and suppresses IFN induction. Biochemical analysis showed that MAVS50, exposing a degenerate TRAF-binding motif within its N-terminus, effectively competed with full-length MAVS for recruiting TRAF2 and TRAF6. Ablation of the TRAF-binding motif of MAVS50 impaired its inhibitory effect on IRF activation and IFN induction. These results collectively identify a new means by which signaling events is differentially regulated via exposing key internally embedded interaction motifs, implying a more ubiquitous regulatory role of truncated proteins arose from internal translation and other related mechanisms., Author Summary Host innate immune signaling plays critical roles in defeating pathogen infection. In response to viral infection, cellular signaling events cumulate in the activation of NF-κB and interferon regulatory factors. How these two signaling ramifications are differentially regulated remains an open question. Here we report an internally translated MAVS variant deregulates IRF activation via exposing N-terminal TRAF-binding motifs. As such, the short form of MAVS efficiently competes for binding to TRAF2 and TRAF6 against full-length MAVS, thereby sequestering key adaptors from the signaling cascades mediated by full-length MAVS. Our study uncovers a delicate regulatory mechanism of truncated proteins bearing key protein-interacting motifs that is enabled by internal translation initiation and potentially other relevant means.

Abstract: Autophagy has a well-documented role in the maintenance of homeostasis and the response to stressful environments and it is often deregulated in various human diseases including cancer. The regulation of the Beclin 1-PI3KC3 complex lipid kinase activity is a critical element in the autophagy signaling pathway. Previous studies1 have demonstrated that Beclin 1-PI3KC3-mediated autophagy is negatively regulated by a proto-oncogene Bcl-2. We have recently identified a novel coiled-coil UVRAG tumor suppressor candidate, which positively engages in Beclin 1-dependent autophagy. UVRAG interacts with Beclin 1, leading to activation of autophagy and thereof inhibition of tumorigenesis. This finding adds a new player to the emerging picture of the autophagy network, underscoring the importance of the coordinated activity between Bcl-2 and UVRAG in the regulation of Beclin 1-PI3KC3- mediated autophagy and tumor cell control.Addendum to:Autophagic and Tumor Suppressor Activity of a Novel Beclin 1-Binding Protein UVRA...

Abstract: For decades, a marvelous amount of work has been performed to identify molecules that regulate distinct stages of membrane transport in the ER-Golgi secretory pathway and autophagy, which are implicated in many human diseases. However, an important missing piece in this puzzle is how the cell dynamically coordinates these crisscrossed trafficking pathways in response to different stimuli. Our recent study has identified UVRAG as a mode-switching protein that coordinates Golgi-ER retrograde and autophagic trafficking. UVRAG recognizes phosphatidylinositol-3-phosphate (PtdIns3P) and locates to the ER, where it couples the ER tethering complex containing RINT1 to govern Golgi-ER retrograde transport. Intriguingly, when autophagy is induced, UVRAG undergoes a "partnering shift" from the ER tethering complex to the BECN1 autophagy complex, resulting in concomitant inhibition of Golgi-ER transport and the activation of ATG9 autophagic trafficking. Therefore, Golgi-ER retrograde and autophagy-related membrane trafficking are functionally interdependent and tightly regulated by UVRAG to ensure spatiotemporal fidelity of protein transport and organelle homeostasis, providing distinguished insights into trafficking-related diseases.

Abstract: UVRAG is a promoter of the autophagy pathway, and its deficiency may fuel the development of cancers. Intriguingly, our recent study has demonstrated that this protein also mediates the repair of damaged DNA and patrols centrosome stability, mechanisms that commonly prevent cancer progression, in a manner independent of its role in autophagy signaling. Given the central role of UVRAG in genomic stability and autophagic cleaning, it is speculated that UVRAG is a bona fide genome protector and that the decrease in UVRAG seen in some cancers may render these cells vulnerable to chromosomal damage, making UVRAG an appealing target for cancer therapy.

Abstract: Bcl-2, originally identified as a universal inhibitor of apoptotic cell death, has since been implicated in suppressing autophagy, the cell’s quality control mechanism. Our recent study demonstrates that the anti-autophagic aspect of Bcl-2 can function as a promoter of oncogenic growth, independently of its role in apoptosis signaling. It is likely that the increase in Bcl-2 often seen in breast and other cancers might render cells error-prone by blunting autophagy, while concomitantly keeping damaged cells alive. The outcome of such a ‘double hit’ of Bcl-2 may synergistically promote tumor growth and increase the chance of cancer development and drug resistance.

Abstract: Autophagy constitutes a major catabolic process for the quality control of internal proteins and organelles of eukaryotic cells, and is emerging as an essential part of the host antiviral defense. Many studies have shed light on the importance of autophagy in homeostasis, but it is not well understood how viruses co-opt the cellular autophagic pathway to establish virulence in vivo. Our recent study presents direct in vivo evidence for the key role of the anti-autophagic aspect of the virally encoded Bcl-2 proteins in the chronic infection of oncogenic gamma-herpesviruses and proposes that cellular autophagy may have a substantial effect on viral persistence and may influence the in vivo fitness of viruses. This discovery expands upon known antiviral activities of the autophagy machinery and also suggests new approaches for treating some virally induced diseases.

Abstract: Autophagy removes long-lived proteins and damaged organelles and is important for maintaining cellular homeostasis. It can also serve in innate immunity to remove intracellular pathogens. As such, viruses have evolved different mechanisms to subvert this innate immune response. We have recently demonstrated that hepatitis C virus (HCV) can also suppress autophagic protein degradation by suppressing the fusion between autophagosomes and lysosomes. This suppression causes the accumulation of autophagosomes and enhances HCV RNA replication.(1) Our further analysis indicated that the induction of autophagosomes by HCV is dependent on the unfolded protein response (UPR). Our studies thus delineate a molecular pathway by which HCV induces autophagosomes. The prolonged perturbation of the autophagic pathway by HCV likely plays an important role in HCV pathogenesis.

Abstract: Gammaherpesviruses such as Epstein-Barr virus (EBV) and Kaposi's sarcoma-associated herpesvirus (KSHV, HHV-8) establish lifelong latency in their hosts and are associated with the development of several types of malignancies, including a subset of B cell lymphomas. These viruses are thought to co-opt the process of B cell differentiation to latently infect a fraction of circulating memory B cells, resulting in the establishment of a stable latency setpoint. However, little is known about how this infected memory B cell compartment is maintained throughout the life of the host. We have previously demonstrated that immature and transitional B cells are long-term latency reservoirs for murine gammaherpesvirus 68 (MHV68), suggesting that infection of developing B cells contributes to the maintenance of lifelong latency. During hematopoiesis, immature and transitional B cells are subject to B cell receptor (BCR)-mediated negative selection, which results in the clonal deletion of autoreactive B cells. Interestingly, numerous gammaherpesviruses encode homologs of the anti-apoptotic protein Bcl-2, suggesting that virus inhibition of apoptosis could subvert clonal deletion. To test this, we quantified latency establishment in mice inoculated with MHV68 vBcl-2 mutants. vBcl-2 mutant viruses displayed a marked decrease in the frequency of immature and transitional B cells harboring viral genome, but this attenuation could be rescued by increased host Bcl-2 expression. Conversely, vBcl-2 mutant virus latency in early B cells and mature B cells, which are not targets of negative selection, was remarkably similar to wild-type virus. Finally, in vivo depletion of developing B cells during chronic infection resulted in decreased mature B cell latency, demonstrating a key role for developing B cells in the maintenance of lifelong latency. Collectively, these findings support a model in which gammaherpesvirus latency in circulating mature B cells is sustained in part through the recurrent infection and vBcl-2-mediated survival of developing B cells., Author Summary Gammaherpesviruses such as Epstein-Barr virus and Kaposi's sarcoma herpesvirus are widespread pathogens that establish lifelong infections in a dormant state termed latency. Although most gammaherpesvirus infections are asymptomatic, infection of some individuals leads to the development of B cell lymphoma or other cancers. It is well known that during latency these viruses reside in mature B cells of the immune system; however, little is known about how this reservoir is maintained for life. Using murine gammaherpesvirus 68 infection of mice as a model to study gammaherpesvirus infections inside a living host, we have previously demonstrated that gammaherpesviruses can infect early precursors of B cells. In normal situations, the differentiation of such precursors into mature B cells is a tightly regulated process that leads to the death of cells that react inappropriately to host tissues. Here though, we demonstrate that a gammaherpesvirus protein called vBcl-2 can block the death of infected precursor B cells, and that vBcl-2 is critical for infection of these cells. Finally, we show that depleting precursor B cells reduces mature B cell latency. Together, these data suggest that vBcl-2 proteins play a key role in lifelong gammaherpesvirus latency and may be a potent target for future drug development.

Abstract: Autophagy constitutes a major catabolic hub for the quality control of intracellular entities of eukaryotic cells, and is emerging as an essential part of the host antiviral defense mechanism. However, in turn, viruses have evolved elegant strategies to co-opt various stages of the cellular autophagy pathway to establish virulence in vivo. This is particularly the case in the ubiquitous and persistent herpesvirus infection. In this review, I will focus on recent findings regarding the crosstalk between the herpes virus family and the autophagy pathway, with a look at the molecular mechanisms they use to disturb cells" autophagy regulation and eventually result in persistence and pathogenesis.

Abstract: All gammaherpesviruses express homologues of antiapoptotic B-cell lymphoma-2 (BCL-2) to counter the clearance of infected cells by host antiviral defense machineries. To gain insights into the action mechanisms of these viral BCL-2 proteins, we carried out structural and biochemical analyses on the interactions of M11, a viral BCL-2 of murine γ-herpesvirus 68, with a fragment of proautophagic Beclin1 and BCL-2 homology 3 (BH3) domain-containing peptides derived from an array of proapoptotic BCL-2 family proteins. Mainly through hydrophobic interactions, M11 bound the BH3-like domain of Beclin1 with a dissociation constant of 40 nanomole, a markedly tighter affinity compared to the 1.7 micromolar binding affinity between cellular BCL-2 and Beclin1. Consistently, M11 inhibited autophagy more efficiently than BCL-2 in NIH3T3 cells. M11 also interacted tightly with a BH3 domain peptide of BAK and those of the upstream BH3-only proteins BIM, BID, BMF, PUMA, and Noxa, but weakly with that of BAX. These results collectively suggest that M11 potently inhibits Beclin1 in addition to broadly neutralizing the proapoptotic BCL-2 family in a similar but distinctive way from cellular BCL-2, and that the Beclin1-mediated autophagy may be a main target of the virus., Author Summary In higher animals, defective or surplus cells are removed by a process known as apoptosis. On the other hand, defective or damaged cellular components are removed by a process known as autophagy. These two destructive processes are indispensable for the survival and development of an organism. While apoptosis is known as a central host defense mechanism that removes virus-infected cells, the role of autophagy against viral infection has recently emerged. Many viruses express an armory of viral proteins that counteract cell death–mediated innate immune control. One such protein is a homologue of the cellular BCL-2 protein that suppresses apoptosis through inhibitory binding to apoptosis-promoting proteins. Murine γ-herpesvirus 68 also encodes a viral BCL-2, known as M11. In this study, we quantitatively measured the binding affinity of M11 for its potential cellular targets, including ten different proapoptotic proteins and the proautophagic protein Beclin1. We found that M11 neutralizes the proapoptotic proteins broadly rather than selectively to suppress apoptosis. Surprisingly, M11 bound to Beclin1 with the highest affinity, which correlated with its strong antiautophagic activity in cells. These data suggest that M11 suppresses not only apoptosis but also autophagy potently, which ultimately contributes to the viral chronic infection.

Abstract: Upon viral infection, cells undergo apoptosis as a defense against viral replication. Viruses, in turn, have evolved elaborate mechanisms to subvert apoptotic processes. Here, we report that a novel viral mitochondrial anti-apoptotic protein (vMAP) of murine γ-herpesvirus 68 (γHV-68) interacts with Bcl-2 and voltage-dependent anion channel 1 (VDAC1) in a genetically separable manner. The N-terminal region of vMAP interacted with Bcl-2, and this interaction markedly increased not only Bcl-2 recruitment to mitochondria but also its avidity for BH3-only pro-apoptotic proteins, thereby suppressing Bax mitochondrial translocation and activation. In addition, the central and C-terminal hydrophobic regions of vMAP interacted with VDAC1. Consequently, these interactions resulted in the effective inhibition of cytochrome c release, leading to the comprehensive inhibition of mitochondrion-mediated apoptosis. Finally, vMAP gene was required for efficient γHV-68 lytic replication in normal cells, but not in mitochondrial apoptosis-deficient cells. These results demonstrate that γHV-68 vMAP independently targets two important regulators of mitochondrial apoptosis-mediated intracellular innate immunity, allowing efficient viral lytic replication., Author Summary Apoptosis is a conserved cell death program that contributes to restriction of viral replication and elimination of infected cells. Whether triggered via internal inducers such as DNA damage or via external stimuli such as engagement of the death receptor, apoptosis takes place through a cascade of regulated internal proteolytic digestion, resulting in a collapse of cellular infrastructure, mitochondrial potential, genomic fidelity, and cell membrane integrity. Indeed, apoptosis represents a predominant form of virally infected cell demise. In response, viruses have evolved numerous ways of circumventing this host-cell apoptosis. Most of the DNA viruses including murine γ-herpesvirus 68 (γHV-68) are genetically equipped with anti-apoptotic ability to ensure viral replication and propagation. The authors have identified a new viral mitochondrial protein (vMAP) of γHV-68 that interacts with Bcl-2 and voltage-dependent anion channel 1 (VDAC1) in a genetically separable manner. These interactions markedly suppress Bax mitochondrial translocation and activation and inhibit cytochrome c release, leading to the comprehensive inhibition of mitochondrion-mediated apoptosis. The authors also demonstrate that vMAP gene is required for efficient γHV-68 lytic replication in normal cells, but not in mitochondrial apoptosis-deficient cells. These findings are entirely novel and significantly advance our understanding of how virus escapes host intracellular apoptosis-mediated innate immunity.
