Abstract

The self-assembly of amphiphilic molecules usually takes place in a liquid phase, near room temperature. Here, using small angle X-ray scattering (SAXS) experiments performed in real time, we show that freezing of aqueous solutions of copolymer amphiphilic molecules can induce self-assembly below 0{\deg}C., Comment: 10 pages, 3 figures

Sarah Deville,1,2 Wahyu Wijaya Hadiwikarta,1 Nick Smisdom,1,2 Bart Wathiong,1,3 Marcel Ameloot,2 Inge Nelissen,1 Jef Hooyberghs1,3 1VITO, Flemish Institute for Technological Research, Mol, Belgium; 2Biomedical Research Institute, Hasselt University, Diepenbeek, Belgium; 3Theoretical Physics, Hasselt University, Diepenbeek, Belgium Abstract: CD34+ hematopoietic progenitor cells (HPCs) offer great opportunities to develop new treatments for numerous malignant and non-malignant diseases. Nanoparticle (NP)-based strategies can further enhance this potential, and therefore a thorough understanding of the loading behavior of HPCs towards NPs is essential for a successful application. The present study focusses on the interaction kinetics of 40 nm sized carboxylated polystyrene (PS) NPs with HPCs. Interestingly, a transient association of the NPs with HPCs is observed, reaching a maximum within 1 hour and declining afterwards. This behavior is not seen in dendritic cells (CD34-DCs) differentiated from HPCs, which display a monotonic increase in NP load. We demonstrate that this transient interaction requires an energy-dependent cellular process, suggesting active loading and release of NPs by HPCs. This novel observation offers a unique approach to transiently equip HPCs. A simple theoretical approach modeling the kinetics of NP loading and release is presented, contributing to a framework of describing this phenomenon.

Abstract

The treatment resistance of cancer cells is a multifaceted process in which DNA repair emerged as a potential therapeutic target. DNA repair is predominantly conducted by nuclear events; yet, how extra-nuclear cues impact the DNA damage response is largely unknown. Here, using a high-throughput RNAi-based screen in three-dimensionally-grown cell cultures of head and neck squamous cell carcinoma (HNSCC), we identified novel focal adhesion proteins controlling DNA repair, including the intermediate filament protein, synemin. We demonstrate that synemin critically regulates the DNA damage response by non-homologous end joining repair. Mechanistically, synemin forms a protein complex with DNA-PKcs through its C-terminal tail domain for determining DNA repair processes upstream of this enzyme in an ATM-dependent manner. Our study discovers a critical function of the intermediate filament protein, synemin in the DNA damage response, fundamentally supporting the concept of cytoarchitectural elements as co-regulators of nuclear events.

Abstract

In advanced ceramics, improving toughness usually relies on the introduction of a soft metallic or polymeric ductile phase, which decreases the mechanical properties. Some natural materials are strong, stiff and tough due to a combination of mechanisms operating at different length scales. However, such structures have been extremely difficult to replicate into synthetic materials. Here we investigate the microstructure and the micromechanical properties of a bioinspired ceramic-ceramic composite. The micromechanical properties at room temperature show slight differences as a function of the platelet orientation. The hardness strongly decreases with increasing temperatures (up to 550 °C) for all the investigated orientations. The elastic strain to failure, defined as the H/E ratio, was used to estimate the wear resistance of materials, which is higher at room temperature because the dislocation mobility is lower than that at high temperature., Peer Reviewed, Postprint (author's final draft)

Abstract

For better tumor control, high-precision proton beam radiation therapy is currently being intensively discussed relative to conventional photon therapy. Here, we assumed that radiation type-specific molecular response profiles in more physiological 3D, matrix-based head and neck squamous cell carcinoma (HNSCC) cell cultures can be identified and therapeutically exploited. While proton irradiation revealed superimposable clonogenic survival and residual DNA double strand breaks (DSB) relative to photon irradiation, kinome profiles showed quantitative differences between both irradiation types. Pharmacological inhibition of a subset of radiation-induced kinases, predominantly belonging to the mitogen-activated protein kinase (MAPK) family, failed to sensitize HNSCC cells to either proton or photon irradiation. Likewise, inhibitors for ATM, DNA-PK and PARP did not discriminate between proton and photon irradiation but generally elicited a radio-sensitization. Conclusively, our results suggest marginal cell line-specific differences in the radio-sensitivity and DSB repair without a superiority of one radiation type over the other in 3D grown HNSCC cell cultures. Importantly, radiation-induced activity changes of cytoplasmic kinases induced during the first, acute phase of the cellular radiation response could neither be exploited for sensitization of HNSCC cells to photon nor proton irradiation.

Abstract

Trichinellosis, a re-emerging zoonosis in several countries and pig, is the main species responsible for its transmission to human. Vaccination of swine could be an alternative to prevent the risk of human contamination. In order to develop an efficient and safe inactivate vaccine, the choice of the adjuvant is an important issue. The aim of this study was to develop and select potent and safe adjuvants by screening them in an experimental model with a crude soluble antigen from L1 muscular larvae (ML) of Trichinella spiralis (Ts). The efficacy was checked by the quantification of specific antibody levels. Specific and non-specific IgE antibody levels were also assessed. Safety was checked by the assessment of the local reaction at the injection site.Various Montanide® ISA adjuvant formulations including water in oil, oil in water and multiphasic emulsions, but also nanoparticles or microbeads were tested. The results clearly showed differences between the antibody responses induced by the adjuvants and demonstrated the necessity to use an adjuvant to obtain a specific IgG (IgG1or lgG2a) response directed against the total soluble extract of Ts. All the formulations enhanced the humoral immune response. The origin of the oil contained in the emulsions played an important role on the efficacy. Indeed emulsions based on mineral oils were more efficient than those based on metabolisable oils. However it was linked with stronger local reactions. Multiphasic and oil in water emulsions but also nanoparticles failed to induce 1gG2a antibody levels. Microbeads and water in oil formulations based on mineral oils were more efficient. This experimentation allowed then the selection of several adjuvants which efficacy will be further Investigated by a challenge test and an analysis of the cellular populations involved in the mechanism of the immune response.

Abstract

Biomimetic functionalization to confer stealth and targeting properties to nanoparticles is a field of intense study. Extracellular vesicles (EV), sub-micron delivery vehicles for intercellular communication, have unique characteristics for drug delivery. We investigated the top-down functionalization of gold nanoparticles with extracellular vesicle membranes, including both lipids and associated membrane proteins, through mechanical extrusion. EV surface-exposed membrane proteins were confirmed to help avoid unwanted elimination by macrophages, while improving autologous uptake. EV membrane morphology, protein composition and orientation were found to be unaffected by mechanical extrusion. We implemented complementary EV characterization methods, including transmission- and immune-electron microscopy, and nanoparticle tracking analysis, to verify membrane coating, size and zeta potential of the EV membrane-cloaked nanoparticles. While successful EV membrane coating of the gold nanoparticles resulted in lower macrophage uptake, low yield was found to be a significant downside of the extrusion approach. Our data incentivize more research to leverage EV membrane biomimicking as a unique drug delivery approach in the near future.

20. Keap1 inhibition sensitizes head and neck squamous cell carcinoma cells to ionizing radiation via impaired non-homologous end joining and induced autophagy

Abstract

The function of Keap1 (Kelch-like ECH-associated protein 1), a sensor of oxidative and electrophilic stress, in the radiosensitivity of cancer cells remains elusive. Here, we investigated the effects of pharmacological inhibition of Keap1 with ML344 on radiosensitivity, DNA double strand break (DSB) repair and autophagy in head and neck squamous cell carcinoma (HNSCC) cell lines. Our data demonstrate that Keap1 inhibition enhances HNSCC cell radiosensitivity. Despite elevated, Nrf2-dependent activity of non-homologous end joining (NHEJ)-related DNA repair, Keap1 inhibition seems to impair DSB repair through delayed phosphorylation of DNA-PKcs. Moreover, Keap1 inhibition elicited autophagy and increased p62 levels when combined with X-ray irradiation. Our findings suggest HNSCC cell radiosensitivity, NHEJ-mediated DSB repair and autophagy to be co-regulated by Keap1.

Abstract

The intermediate filament synemin has been previously identified as novel regulator of cancer cell therapy resistance and DNA double strand break (DSB) repair. c-Abl tyrosine kinase is involved in both of these processes. Using PamGene technology, we performed a broad-spectrum kinase activity profiling in three-dimensionally, matrix grown head and neck cancer cell cultures. Upon synemin silencing, we identified 86 deactivated tyrosine kinases, including c-Abl, in irradiated HNSCC cells. c-Abl hyperphosphorylations on tyrosine (Y) 412 and threonine (T) 735 upon irradiation were significantly reduced after synemin inhibition prompting us to hypothesize that c-Abl tyrosine kinase is an important signaling component of the synemin-mediated radioresistance pathway. Simultaneous targeting of synemin and c-Abl resulted in similar radiosensitization and DSB repair compared with single synemin depletion suggesting synemin as an upstream regulator of c-Abl. Immunoprecipitation assays revealed a protein complex formation between synemin and c-Abl pre- and post-irradiation. Upon pharmacological inhibition of ATM, synemin/c-Abl protein-protein interactions were disrupted implying synemin function to depend on ATM kinase activity. Moreover, deletion of the ∆SH2 domain in c-Abl demonstrated a decrease in interaction indicating the dependency of the protein-protein interaction on this domain. Mechanistically, impairment of DNA repair seems to be related with radiosensitization upon synemin knockdown via regulation of non-homologous end joining, independent of c-Abl function. Our data generated in more physiological 3D cancer cell culture models suggest c-Abl as further key determinant of radioresistance downstream of synemin.

Abstract

© 2018, © 2018 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group on behalf of The International Society for Extracellular Vesicles. The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and amount often make them difficult to obtain as relatively pure preparations, and to characterize properly. The International Society for Extracellular Vesicles (ISEV) proposed Minimal Information for Studies of Extracellular Vesicles (“MISEV”) guidelines for the field in 2014. We now update these “MISEV2014” guidelines based on evolution of the collective knowledge in the last four years. An important point to consider is that ascribing a specific function to EVs in general, or to subtypes of EVs, requires reporting of specific information beyond mere description of function in a crude, potentially contaminated, and heterogeneous preparation. For example, claims that exosomes are endowed with exquisite and specific activities remain difficult to support experimentally, given our still limited knowledge of their specific molecular machineries of biogenesis and release, as compared with other biophysically similar EVs. The MISEV2018 guidelines include tables and outlines of suggested protocols and steps to follow to document specific EV-associated functional activities. Finally, a checklist is provided with summaries of key points.

Abstract

Alterations in mechano-physiological properties of a tissue instigate cancer burdens in parallel to common genetic and epigenetic alterations. The chronological and mechanistic interrelation between the various extra- and intracellular aspects remains largely elusive. Mechano-physiologically, integrins and other cell adhesion molecules present the main mediators for transferring and distributing forces between extracellular matrix (ECM), via focal adhesomes to cytoskeleton and nucleus and vice versa of the single cell thereby affecting the pathophysiology of multicellular cancer tissues. In combina-tion with simultaneous activation of diverse downstream signaling pathways, the phenotypes of can-cer cells are created and driven characterized by deregulated transcriptional and biochemical cues that elicit the hallmarks of cancer. It, however, remains unclear how elastostatic modifications, i.e. stiffness, in the extracellular, intracellular and nuclear compartment contribute and control the re-sistance of cancer cells to therapy. In this review, we discuss how stiffness of unique tumor compo-nents dictates therapy response and what is known about the underlying molecular mechanisms.

Abstract

Background: Therapy resistance is a great challenge during cancer treatment. A well-known determinant of radiochemoresistance is cell adhesion to extracellular matrix. Targeting focal adhesion proteins (FAPs) has been shown to enhance cancer radiochemosensitivity in various tumor entities. Previous studies demonstrated a functional crosstalk between specific FAPs and DNA repair processes; however, the molecular mechanism remains unsolved. This study aimed to identify alternative FAPs associated with DNA damage repair mechanisms and radioresistance in head and neck squamous cell carcinomas (HNSCC). Materials and Methods: A novel 3D High Throughput RNAi Screen (3DHT-RNAi-S) using laminin-rich extracellular matrix was established to determine radiation-induced residual DNA double strand breaks (DSBs) and clonogenic radiation survival using UTSCC15 cells expressing pEGFP-53BP1. Validations were performed in 10 3D grown HNSCC cell lines. DNA repair mechanisms, protein expression and kinetics post irradiation were investigated using immuno-fluorescence/-blotting, reporter assays for DSB repair activity and kinase activity profiling (PamGene) upon protein knockdown with/-out X-ray exposure. Protein-protein interactions were determined using immunoprecipitation (IP) and proximity ligation assay. Results: In the 3DHT-RNAi-S, Synemin emerged as resulted one of the most promising candidates to determine HNSCC cell radiosensitivitysurvival and DNA damage repair. Synemin silencing radiosensitized HNSCC cells, while its exogenous overexpression induced radioprotection. Synemin depletion elicited a 40% reduction in non-homologous end joining activity without affecting other DNA DSB repair mechanisms. In line, ATM, DNA-PKcs and c-Abl phosphorylation as well as Ku70 expression strongly declined in synemin depleted and irradiated cells relative to controls. In kinome analysis, tyrosine kinases showed significantly reduced activity after synemin silencing relative to controls. Furthermore, IP revealed a protein complex formed between synemin, DNA-PKcs and c-Abl. This protein complex dispersed when ATM was pharmacologically inhibited. Using different protein constructs of synemin (ΔLink-Tail, ΔHead-Link, Synemin_301-961, Synemin_962-1565, S1114A and S1159A), the phosphorylation site at the serine 1114 located on the distal portion of synemin´s tail was identified as essential protein-protein interaction site involved in synemin´s function in DNA repair. Using different protein constructs with domain deletions of synemin, the distal portion of synemin´s tail was identified as essential protein site regulating synemin´s function in DNA repair processes. Conclusions: The 3DHT-RNAi-S provides a robust screening platform for identifying novel targets involved in therapy resistance. Based on this screen and detailed mechanistic analyses, the intermediate filament synemin was discovered as a novel important determinant of DNA repair, tyrosine kinase activity and radioresistance of HNSCC cells. These results fundamentally support the concept of cytoarchitectural elements as co-regulators of nuclear events.further support the concept that DNA repair is regulated by cooperative interactions between nuclear and cytoplasmic proteins.

Abstract

The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and amount often make the

Abstract

Introduction: Focal adhesion proteins (FAPs) have been shown to be essential determinants of cancer therapy outcome. Our previous findings revealed the role of FAPs in DNA repair processes. Here, we characterized the unknown and novel functions of Synemin, an intermediate filament protein, which functions as FAP, as novel double strand break (DSB) repair and as tyrosine kinase regulator in head and neck squamous cell carcinoma (HNSCC). Materials and methods: Using a novel 3D High Throughput RNAi Screen (3D HTP-RNAi-S), clonogenic survival and double strand breaks (DSB) repair in non- and -irradiated HNSCC were analyzed upon knockdown of 117 FAP. Confirmatory data were generated in a panel of 10 HNSCC cell lines. Reporter gene assays were applied to determine the efficiency in DNA DSB repair by non-homologous end joining (NHEJ) and homologous recombination (HR). Western blot was used to determine protein expression and phosphorylation. Immunoprecipitation (IP) and kinase activity profiling (PamGene) were carried out to determine Synemin interactome. Results and Discussion: Among the potential FAP targets from our 3D HTP-RNAi-S, Synemin turned out as a novel and most promising candidate in controlling HNSCC radiosensitivity. Intriguingly, Synemin depletion induced a 40% reduced NHEJ activity while leaving HR unchanged. We demonstrated significant dephosphorylation of DNA-PKcs kinase, a key component of the NHEJ pathway, as well as reduced levels of Ku70 in Synemin depleted, irradiated HNSCC cells as compared to controls. We further demonstrated an almost comprehensive deactivation of 86 tyrosine kinases after Synemin silencing. Among these, bioinformatic analysis revealed c-Abl highly downregulated at 24 hours post irradiation in Synemin-depleted HNSCC cells. Co-IP revealed an interaction between Synemin and c-Abl suggesting those proteins to form a protein complex. Single, double and triple depletion of Synemin, DNA-PKcs, and c-Abl resulted in similar radiosensitization and DSB levels, suggesting Synemin to be located upstream of these DNA repair kinases. Conclusion: Our data suggest the intermediate filament Synemin as a novel determinant of DNA repair, tyrosine kinase regulation and radiosensitivity of HNSCC cells. These observations further support the notion that DNA repair is controlled by cooperative interactions between nuclear, membrane and cytoplasmic proteins.

Abstract

Introduction: Cancer therapy resistance is one of the major obstacles for higher cure rates. Novel key players of the resistome are focal adhesion proteins (FAPs). As FAPs are critically involved in DNA repair, we here characterize the yet unknown function of the FAP and intermediate filament protein Synemin (SYN) as a novel DNA repair regulator and potential cancer drug target in head and neck squamous cell carcinoma (HNSCC). Methods and materials: Our novel 3D High Throughput esiRNA Screen (3DHTesiRNAs) using laminin-rich extracellular matrix (lrECM) was conducted to measure radiation-induced residual DNA double strand breaks (DSBs; foci assay) and clonogenic radiation survival in UTSCC15-pEGFP-53BP1 cells. Validations were performed in 10 additional HNSCC cell lines in 3D lrECM. Upon SYN depletion, DSB repair reporter assays for non-homologous end joining (NHEJ) and homologous recombination (HR) as well as Western Blotting for protein expression and phosphorylation were carried out. SYN depleted cells with and without irradiation were analyzed for kinase activity profiling (PamGene) and protein interactome determination using a sequential immunoprecipitation/mass spectrometry approach. Results and Discussion: Among the targets found in the 3DHTesiRNAs, SYN turned out as one of the top FAP candidate determinants of HNSCC cell survival. SYN silencing radiosensitized HNSCC cells, while its exogenous overexpression induced radioprotection. We found an increased SYN/chromatin interaction and a marked perinuclear SYN accumulation post irradiation. Intriguingly, SYN depletion elicited a 40% reduction in NHEJ activity without affecting HR or alt-EJ. In line, ATM, DNA-PKcs and c-Abl phosphorylation as well as Ku70 expression strongly declined in SYN depleted and irradiated cells relative to controls and, in contrast, to the rescue of these protein modifications by SYN overexpression. Single, double and triple depletion of SYN, DNA-PKcs and c-Abl resulted in similar radiosensitization and DSB levels as observed for SYN only, suggesting its upstream role. In the kinome analysis we observed variable changes in the serine/threonine kinases, in contrast to the tyrosine kinases with a pronounce reduced kinase activity after SYN silencing. Conclusion: Our data suggest the intermediate filament SYN as a new important determinant of DNA repair, tyrosine kinome and radioresistance of HNSCC cells. These observations further support the notion that DNA repair is controlled by cooperative interactions between nuclear and cytoplasmic proteins.

Abstract

The last decade has seen a sharp increase in the number of scientific publications describing physiological and pathological functions of extracellular vesicles (EVs), a collective term covering various subtypes of cell-released, membranous structures, called exosomes, microvesicles, microparticles, ectosomes, oncosomes, apoptotic bodies, and many other names. However, specific issues arise when working with these entities, whose size and amount often make them difficult to obtain as relatively pure preparations, and to characterize properly. The International Society for Extracellular Vesicles (ISEV) proposed Minimal Information for Studies of Extracellular Vesicles ("MISEV") guidelines for the field in 2014. We now update these "MISEV2014" guidelines based on evolution of the collective knowledge in the last four years. An important point to consider is that ascribing a specific function to EVs in general, or to subtypes of EVs, requires reporting of specific information beyond mere description of function in a crude, potentially contaminated, and heterogeneous preparation. For example, claims that exosomes are endowed with exquisite and specific activities remain difficult to support experimentally, given our still limited knowledge of their specific molecular machineries of biogenesis and release, as compared with other biophysically similar EVs. The MISEV2018 guidelines include tables and outlines of suggested protocols and steps to follow to document specific EV-associated functional activities. Finally, a checklist is provided with summaries of key points.

Abstract

Introduction: Focal adhesion proteins (FAPs) have been shown to essentially contribute to cancer cell therapy resistance. Based on our previous finding that integrins partially control DNA repair processes, we here aim at characterizing the function of FAPs in the DNA damage response. Among others, we identified Synemin, an intermediate filament protein, as novel DNA repair regulator and highly potential novel cancer target in head and neck squamous cell carcinoma (HNSCC). Methods and materials: A novel 3D High Throughput esiRNA Screen (3DHTesiRNAs) using (3D)-laminin-rich extracellular matrix (lr-ECM) was established. Screening for residual double strand breaks (DSBs) and clonogenic radiation survival was performed in UTSCC15-pEGFP-53BP1 HNSCC cells upon esiRNA-mediated FAPs knockdown and X-ray exposure (6 Gy). The top 2 targets were validated in a panel of 10 3D lr-ECM HNSCC cell cultures regarding γH2AX/53BP1 foci and clonogenic survival. Immunostaining and 3D chromatin fractionation (CF) of Synemin prior and post irradiation (IR) were performed. Upon Synemin knockdown, DNA repair assay for NHEJ and HR as well as Western Blotting for protein expression and phosphorylation were employed. Results: Among a number of interesting novel targets found in our 3DHTesiRNAs, Synemin turned out as novel determinant of HNSCC radiosensitivity. Synemin silencing led to radiosensitization of 3D HNSCC cell cultures. Intriguingly, we showed that Synemin knockdown resulted in a 40% reduction in NHEJ without affecting HR. Concomitantly, phosphorylation of ATM Ser1981, DNA-PKcs Ser2056 and c-Abl Tyr412 were diminished relative to controls. Associated with these observations, we found a dramatic Synemin accumulation in the perinuclear area, which is accompanied by an increased interaction of Synemin with chromatin. Conclusion: Our data indicate the interfilament protein Synemin as a new important determinant of DNA repair and radioresistance in HNSCC cells. Ongoing research is focusing on evaluating the molecular mechanism how Synemin participates in NHEJ and chromatin organization.

Abstract

International audience; Sintering of green samples of alumina produced by ice-templating was followed in situ in an environmental scanning electron microscope (ESEM) up to temperatures as high as 1375 degrees C. These alumina samples with well-defined architectures are of great interest in the field of materials science due to their high specific strength (especially in compression), low density and adaptable porosity. For the present study, they also have the advantage to exhibit an important topography, inducing interesting contrast when imaged in an ESEM. Improvements of the imaging conditions in the ESEM were essential to really follow the sintering process involving formation of necks between grains or shift of the centre of grains. This paper describes the improvements made and the results observed on the sintering process of alumina green samples processed by ice-templating.

Abstract

International audience; The solidification behaviour of suspensions of alumina particles during directional solidification is investigated here by in situ observations using X-ray radiography and tomography. The objective of this study is to assess the influence of particle size on the solidification behaviour of the suspensions during the early stages of solidification. Four powders with particle size in the range 0.2–3.4 μm (median size) were investigated. Solidification is obtained by cooling at a constant rate, starting from room temperature. Attention is specifically paid to the nucleation and growth behaviour of the ice crystals in these suspensions. We propose that the nucleation of ice crystals is controlled by the particle size, the surface of the particles acting as nucleation sites. Smaller particle size leads to a lower degree of supercooling since nucleation and growth can proceed at higher temperature than with larger particles. The initial interface velocity is dependent on the degree of supercooling, and controls the extent of the initial structural gradient in the resulting porous materials.
