Amadori compounds (ACs) are key intermediates of the Maillard reaction, and found in various thermally processed foods. Simultaneous analysis of multiple ACs is challenging due to the complex amino acid and carbohydrate compositions, and the different food matrices. Most studies focus on the effects of ACs on food flavor and related sensory properties, but not their biological functions. However, increasing evidence shows that ACs possess various beneficial effects on human health, thus a comprehensive review on the various biological activities is warranted. In this review, we summarized the composition and content of ACs in different foods, their formation and degradation reactions, and discussed the latest advances in analytical methods of ACs and their biological functions related to human health. Limitations and research gaps were identified and future perspectives on ACs research were proposed. This review points to the needs of systematic and comprehensive in vitro and in vivo studies on human health related biological functions of ACs and their mechanisms of action, particularly the synergistic effects with other food components and drugs, and roles in intestinal health and metabolic syndrome.

The study analyzed the aqueous leaf extracts of Moringa oleifera and Musa sps. for phytochemical components, including flavonoids, sterols, saponins, tannins, and glycosides. The LC–MS analysis revealed gingerol, vicenin-2, caffeic acid, quercetin, and other compounds in the extracts. The synthesized MO- and MS- CuNPs (copper nanoparticles) exhibited plasmon resonance at 320 and 480 nm respectively, and Cu(II)-O stretching vibrations, manifested by their Fourier Transform Infrared (FT-IR) spectra. Thermogravimetric analysis showed that MO-/MS-CuNPs experienced a total weight loss of 80.2% and 68% respectively. Further, the EDS analysis revealed that MO-CuNPs have a copper content of 20%, while MS-CuNPs is 32%. The X-ray diffraction (XRD) patterns of the annealed MO and MS-CuNPs indicate the presence of both the cubic phase of copper (Cu) and the monoclinic tenorite phase of copper oxide (CuO). The percent DPPH scavenging activity of MO- and MS-CuNPs is 34.4 and 28.8, and by KMnO4 is 63.8 and 47.3% respectively. The behavior of CuNPs exhibited an asymmetrical response, with greater inhibition of Gram-negative bacteria compared to Gram-positive bacteria. CuNPs and medicinal plant-derived carbon dots were integrated into nanofibrous electrospun biopolymer scaffolds for wound care, demonstrating 100% wound healing in Yorkshire pigs full thickness excision wounds after 34 days.

Bile acids (BAs), a category of amphiphilic metabolites synthesized by liver cells and released into the intestine via the bile duct, serve a vital role in the emulsification of ingested fats during the digestive process. Beyond their conventional emulsifying function, BAs, with their diverse structures, also act as significant hormones within the body. They are pivotal in facilitating nutrient absorption by interacting with the farnesoid X receptor (FXR), and they serve as key regulators of lipid and glucose metabolism, as well as immune system balance. Consequently, BAs contribute to the metabolism of glucose and lipids, enhance the digestion and absorption of lipids, and maintain the equilibrium of the bile pool. Their actions are instrumental in addressing obesity, managing cholestasis, and treating diabetes, and are involved in the onset and progression of cancer. This paper presents an updated systematic review of the pharmacological mechanisms by which BAs target the FXR, incorporating recent findings and discussing their signaling pathways in the context of novel research, including their distinct roles in various disease states and populations. The aim is to provide a theoretical foundation for the continued research and clinical application of BAs. [ABSTRACT FROM AUTHOR]

The primary objective here is to underscore the significance of high percentage of crystal boundaries (>50%) of a nanocrystalline (NC) surface in understanding the cellular interaction of fibroblasts with the NC surface of biomedical stainless steel. The favourable cellular functions on the NC surface as compared to the conventional microcrystalline (MC) surface with ~2–3% crystal boundaries are related to the bio-physical characteristics of the crystalline surface. The unveiling of bio-physical characteristics in terms of crystal boundaries is one of the relevant aspects that provides an understanding of the preferred biological functions, notably, cell adhesion, spread and synthesis of proteins on the NC surface in relation to the MC counterpart.

The purpose of this study is to construct a mortality model that reasonably explains survival curves and mortality rates in terms of the decline in biological function, which is the phenomenon of ageing. In this model, an individual organism is regarded as a collection of subsystems, and for each subsystem, the model defines human mortality by introducing positive self-repair mechanisms and stochastically generated negative external shocks. The probability density function of the time of death is derived explicitly, and the model parameters are estimated using life tables from Japan and the UK, which demonstrate the existence of multiple parameter sets that fit well with the observed data.

In recent years, cancer, especially primary liver cancer (including hepatocellular carcinoma and intrahepatic cholangiocarcinoma), has posed a serious threat to human health. In the field of liver cancer, exosomes play an important role in liver cancer initiation, metastasis and interaction with the tumor microenvironment. Exosomes are a class of nanoscale extracellular vesicles (EVs)secreted by most cells and rich in bioactive molecules, including RNA, proteins and lipids, that mediate intercellular communication during physiological and pathological processes. This review reviews the multiple roles of exosomes in liver cancer, including the initiation, progression, and metastasis of liver cancer, as well as their effects on angiogenesis, epithelial-mesenchymal transformation (EMT), immune evasion, and drug resistance. Exosomes have great potential as biomarkers for liver cancer diagnosis and prognosis because they carry specific molecular markers that facilitate early detection and evaluation of treatment outcomes. In addition, exosomes, as a new type of drug delivery vector, have unique advantages in the targeted therapy of liver cancer and provide a new strategy for the treatment of liver cancer. The challenges and prospects of exosomebased immunotherapy in the treatment of liver cancer were also discussed. However, challenges such as the standardization of isolation techniques and the scalability of therapeutic applications remain significant hurdles. [ABSTRACT FROM AUTHOR]

Background: Type 2 diabetes mellitus (T2DM) is a metabolic disorder, and urinary exosomal microRNAs (miRNAs) were utilized as potential disease prediction or diagnostic biomarkers in numerous studies. This study investigated the differential expression of urinary exosomal miRNAs between non-diabetes mellitus (NDM) individuals and those with T2DM. Aim: To elucidate the association between urinary exosomal miRNAs and T2DM. Methods: We recruited patients diagnosed with T2DM and NDM individuals in West China Hospital, Sichuan University, from November 2023 to February 2024. Subsequently, we performed sequencing of urinary exosomal microRNAs in both groups. The obtained sequencing results were further validated using RT-qPCR in both the training set and the validation set. Additionally, we conducted logistic regression analysis and Spearman correlation analysis on miRNAs with significant differential expression, as well as analysis of their biological functions. Results: A total of 118 urine samples were collected, 59 from individuals diagnosed with T2DM and 59 from NDM. There were differentially expressed miR-183-5p (p = 0.034) and miR-125a-5p (p = 0.008) between the two groups. Furthermore, multivariate regression analysis demonstrated that higher miR-125a-5p levels were negatively associated with the risk of T2DM (p = 0.044; OR: 0.046; 95% CI: 0.002, 0.922). Bioinformatics analysis indicated that the target genes of miR-183-5p were predominantly involved in insulin signaling and glucose transport processes, while those target genes of miR-125a-5p primarily mediated autophagy. Conclusions: miR-183-5p and miR-125a-5p might be involved in the pathogenesis of T2DM, while higher urinary exosomal miR-125a-5p was negatively associated with the risk of T2DM.

Lung cancer (LC) is considered to have the highest mortality rate around the world. Because there are no early diagnostic signs or efficient clinical alternatives, distal metastasis and increasing numbers of recurrences are a challenge in the clinical management of LC. Long non-coding RNAs (lncRNAs) have recently been recognized as a critical regulator involved in the progression and treatment response to LC. The Wnt/β-catenin pathway has been shown to influence LC occurrence and progress. Therefore, discovering connections between Wnt signaling pathway and lncRNAs may offer new therapeutic targets for improving LC treatment and management. In this review, the purpose of this article is to present possible therapeutic approaches by reviewing particular relationships, key processes, and molecules associated to the beginning and development of LC.

Sugars will eventually be exported transporter (SWEET) is a novel class of sugars transporter families which mainly mediate either sucrose or hexose translocation bidirectional across the cellular membranesfollowinga concentrating gradient with a passive diffusion patten. In higher plants, SWEET proteins commonly have seven transmembrane domains that form a pore in the membrane to allow the passage of sugars, containing two MtN3/Saliva domains. Phylogenetically, plant SWEETs are divided into four clades. SWEET transporters play important roles in diverse physiological and biochemical processes including phloem loading, plant hormone transportand vegetative growth. In this review, based on the current advance of the plant SWEET transporters, we summarized their discovery, structure characteristicsand biological functions, and pointed out current research problems. Finally,put forward several better future research directions and potential solutions for SWEET sugar transporters in plant from the following three aspects: 1) exploring the molecular mechanism of substrate recognition and selectivity of SWEET proteins; 2) mining and utilizing of key SWEET genes increasing crop yield and improving quality; 3) using gene editing technology and phosphorylation of SWEET transporters to engineer high-yielding and high-quality crops.

Abstract Background & aims Perilipin 1 (PLIN1) is an essential lipid droplet surface protein that participates in cell life activities by regulating energy balance and lipid metabolism. PLIN1 has been shown to be closely related to the development of numerous tumor types. The purpose of this work was to elucidate the clinicopathologic significance of PLIN1 in hepatocellular carcinoma (HCC), as well as its impact on the biological functions of HCC cells, and to investigate the underlying mechanisms involved. Methods Public high-throughput RNA microarray and RNA sequencing data were collected to examine PLIN1 levels and clinical significance in patients with HCC. Immunohistochemistry (IHC) and real-time quantitative reverse transcription polymerase chain reaction (RT‒qPCR) were conducted to assess the expression levels and the clinicopathological relevance of PLIN1 in HCC. Then, SK and Huh7 cells were transfected with a lentivirus overexpressing PLIN1. CCK8 assay, wound healing assay, transwell assay, and flow cytometric analysis were conducted to explore the effects of PLIN1 overexpression on HCC cell proliferation, migration, invasion, and cell cycle distribution. Ultimately, Gene Ontology (GO) functional annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed to investigate the underlying mechanisms of PLIN1 in HCC progression based on HCC differentially expressed genes and PLIN1 co-expressed genes. Results PLIN1 was markedly downregulated in HCC tissues, which correlated with a noticeably worse prognosis for HCC patients. Additionally, PLIN1 overexpression inhibited the proliferation, migration, and invasion of SK and Huh7 cells in vitro, as well as arresting the HCC cell cycle at the G0/G1 phase. More significantly, energy conversion-related biological processes, lipid metabolism, and cell cycle signalling pathways were the three most enriched molecular mechanisms. Conclusion The present study revealed that PLIN1 downregulation is associated with poor prognosis in HCC patients and accelerated HCC progression by promoting cellular proliferation, migration, and metastasis, as well as the mechanisms underlying the regulation of lipid metabolism-related pathways in HCC.

Abstract Xanthomonas oryzae pv. oryzae (Xoo) causes bacterial blight in rice. Polyhydroxyalkanoates (PHAs) consitute a diverse group of biopolyesters synthesized by bacteria under nutrient-limited conditions. The phaC gene is important for PHA polymerization. We investigated the effects of phaC gene mutagensis in Xoo strain PXO99A. The phaC gene knock-out mutant exhibited reduced swarming ability relative to that of the wild-type. Under conditions where glucose was the sole sugar source, extracellular polysaccharide (EPS) production by ΔphaC declined by 44.8%. ΔphaC showed weak hypersensitive response (HR) induction in the leaves of non-host Nicotiana tabacum, concomitant with downregulation of hpa1 gene expression. When inoculated in rice leaves by the leaf-clipping method, ΔphaC displayed reduced virulence in terms of lesion length compared with the wild-type strain. The complemented strain showed no significant difference from the wild-type strain, suggesting that the deletion of phaC in Xoo induces significant alterations in various physiological and biological processes. These include bacterial swarming ability, EPS production, transcription of hrp genes, and glucose metabolism. These changes are intricately linked to the energy utilization and virulence of Xoo during plant infection. These findings revealed involvement of phaC in Xoo is in the maintaining carbon metabolism by functioning in the PHA metabolic pathway.

Selenium-enriched edible fungi are rich in selenium polysaccharides, selenoproteins, selenium polypeptides and other bioactive components. However, the selenium forms and organic selenium transformation rate of selenium-enriched edible fungi are affected by several factors, such as species, selenium biotransformation methods and cultivation techniques. Subsequently, edible fungi show different biological activities and mechanisms of action. Therefore, it is particularly important to study the forms, distribution, absorption and transformation of selenium in edible fungi. The paper reviews the proportion of different forms of selenium in total selenium, the process of absorption and transformation of different selenium forms, the threshold of total selenium, the present selenium-enriched technology and the industrial problems of representative selenium-enriched edible fungi. The immunological activity, antitumor activity and antioxidant activity of different selenium forms in selenium-enriched edible fungi are also discussed in this paper. This review is expected to provide a reference basis for the precise selenium enrichment of edible fungi, to serve as a scientific support for the development of highly active different forms of selenium, and to propose directions for the development of selenium-enriched edible fungi.

Background. Emerging research has identified ferroptosis as a novel form of programmed cell death, and Arachidonic acid 15-lipoxygenase-1 (ALOX15) stands out as a pivotal gene in mediating this process. Nonetheless, the role of ALOX15 in human tumors remains elusive. Methods. We utilized TIMER 2.0 to investigate the differential expression profiles of ALOX15 between pan-cancer and normal tissues. Further data from the TCGA, GEPIA, UALCAN, HPA, and CPTAC databases were analyzed to verify the levels of mRNA, protein expression, and promoter methylation across various cancer types. The survival prognosis, clinical features, and genetic alterations of ALOX15 were also evaluated. GO/KEGG enrichment analyses and single-cell transcriptome sequencing were employed for functional enrichment analysis. The gene mutation of ALOX15 and its prognostic value were analyzed using the cBioPortal platform. Finally, the relationship between ALOX15 and immune cell infiltration, Immune Checkpoints (ICKs), genomic instability, and drug sensitivity was further explored using GSCA. Results. Our findings revealed that the transcription and protein expression of ALOX15 were significantly reduced in HNSC, LUAD, LUSC, SKCM, KICH, and THCA, while they were up-regulated in ESCA, LIHC, PRAD, and UCEC. Notably, the expression of ALOX15 had prognostic value for certain cancers, including LUAD, LUSC, LIHC, KIRC, HNSC, THCA, and LGG. Additionally, ALOX15 expression was markedly correlated with clinical characteristics, immune cell infiltration, ICKs, genomic instability, and antitumor drug sensitivity in various tumors. Gene mutations of ALOX15 and their prognostic value were discovered in pan-cancers. Furthermore, GO/KEGG analysis and single-cell transcriptome sequencing indicated that ALOX15 was significantly associated with cancer-related pathways. Conclusion. Our comprehensive pan-cancer analysis shed light on the role and significance of ALOX15, suggesting its potential as a prognostic and immunotherapeutic marker for pan-cancer. These findings may provide new directions and evidence for cancer therapeutics. [ABSTRACT FROM AUTHOR]

DNase II, identified in 1947 and named in 1953, is an acidic DNA endonuclease prevalent across organisms and crucial for normal growth. Despite its expression in nearly all human tissues, as well as its biological significance, DNase II's detailed functions and corresponding mechanisms remain unclear. Although many groups are trying to figure this out, progress is very limited. It is very hard to connect its indispensability with its DNA cleavage activity. In this study, we find that DNase II secreted to saliva can digest RNA in mildly acidic conditions, prompting us to hypothesize that salivary DNase II might digest RNA in the stomach. This finding is consistent with the interesting discovery reported in 1964 that RNA could inhibit DNase II's activity, which has been largely overlooked. This RNA digestion activity is further confirmed by using purified DNase II, showing activity to digest both DNA and RNA effectively. Here, we suggest redesignating DNase II as DNase II (RNase). The biological functions of DNase II are suggested to recycle intracellular RNA or digest external nucleic acids (both RNA and DNA) as nutrients. This discovery may untangle the mystery of DNase II and its significant biofunctions. [ABSTRACT FROM AUTHOR]

This study addresses the growing interest in natural functional ingredients by evaluating the prebiotic and health-promoting functions of honeybee brood biopeptides (HBb-Bps) and their conjugates. The purpose was to investigate their antioxidant activities, enzyme inhibition properties, and effects on probiotic growth and short-chain fatty acid (SCFA) production. The HBb-Bps were conjugated with honey, glucose, and fructose via the Maillard reaction. Antioxidant activities were assessed using DPPH and ABTS assays. The inhibitory effects on amylase, pancreatic lipase, and the angiotensin-converting enzyme (ACE) were measured. Probiotic growth and SCFA production were evaluated using L. plantarum TISTR846, and L. lactis TISTR1464. The HBb-Bps and their conjugates exhibited enhanced antioxidant activities post-Maillard reaction. They showed moderate enzyme inhibition, which decreased after conjugation. However, ACE inhibition increased with conjugation. The HBb-Bps significantly promoted probiotic growth and SCFA production, with further enhancement by the Maillard reaction. Overall, the HBb-Bps and their conjugates demonstrate significant prebiotic and health-promoting functions, suggesting their potential as natural ingredients in functional foods and nutraceuticals. Further research should focus on the in vivo effects and, given their solubility and stability these biopeptides could be incorporated into functional food formulations, such as health beverages, protein bars, and other fortified foods designed to deliver specific health benefits.

When animals are exposed to high temperatures, their normal thermoregulation is disrupted, resulting in the occurrence of heat stress. This condition manifests itself in various symptoms such as decreased feed intake, reduced productive performance, weakened immune function, and decreased disease resistance. In severe cases, it can even lead to acute mortality, causing significant losses in the animal farming industry. Selenium, a trace element essential for normal physiological activities in animal organisms, possesses a range of functions including antioxidation, anticancer properties, antimicrobial activity, antiparasitic effects, and antiviral capabilities. In comparison to other forms of selenium, selenium nanoparticles (SeNPs) exhibit lower toxicity, higher biological activity, and better absorption, making them more effective in alleviating heat stress in animals. This article provides a comprehensive overview of the impact of heat stress on animal organisms, the biological functions of SeNPs, relevant synthesis techniques, and their applications in mitigating heat stress in animals. It serves as a reference for future research on the use of SeNPs in alleviating heat stress in animals. [ABSTRACT FROM AUTHOR]

Background: The concept of gene fusion describes the process of fusing two genes into one, which is closely linked to tumour occurrence and development and may even be the direct cause of some tumours. Due to their tumour‐specific expression and ability to drive tumour occurrence and development, there is great potential for fusion genes to be used as diagnostic markers and targets for specific types of tumours. Main body: Although many fusion genes have been detected so far, they mainly focus on a small number of highly recurrent fusion genes detected in patients' tumours. There are few studies on the functional mechanism and clinical relevance of rare gene fusions. Our review discusses the generation mechanisms, detection methods, biological functions, and mechanisms of action of fusion genes. Additionally, we discuss the clinical significance of fusion gene detection in some tumour types. Conclusion: The function mechanism research of rare gene fusion is very necessary, and more functions of fusion genes independent of unfused/normal genes can be explored in future studies. There is still a long way to go in implementing precision tumour therapy targeting gene fusion. [ABSTRACT FROM AUTHOR]

ARAP1-AS1 is prominently overexpressed in numerous solid tumors and wields influence by modulating gene expression and signaling pathways. This regulatory impact is realized through dual mechanisms, involving both competitive interactions with microRNAs and direct protein binding. ARAP1-AS1 assumes an important role in driving tumorigenesis and malignant tumor progression, affecting biological characteristics such as tumor expansion and metastasis. This paper provides a concise review of the regulatory role of ARAP1-AS1 in malignant tumors and discuss its potential clinical applications as a biomarker and therapeutic target. We also address existing knowledge gaps and suggest avenues for future research. ARAP1-AS1 serves as a prototypical example within the burgeoning field of lncRNA studies, offering insights into the broader landscape of non-coding RNA molecules. This investigation enhances our comprehension of the complex mechanisms that govern the progression of cancer. [ABSTRACT FROM AUTHOR]

Mammalian glycosaminoglycans (GAGs), except hyaluronan (HA), are sulfated polysaccharides that are covalently attached to core proteins to form proteoglycans (PGs). This article summarizes key biological findings for the most widespread GAGs, namely HA, chondroitin sulfate/dermatan sulfate (CS/DS), keratan sulfate (KS), and heparan sulfate (HS). It focuses on the major processes that remain to be deciphered to get a comprehensive view of the mechanisms mediating GAG biological functions. They include the regulation of GAG biosynthesis and postsynthetic modifications in heparin (HP) and HS, the composition, heterogeneity, and function of the tetrasaccharide linkage region and its role in disease, the functional characterization of the new PGs recently identified by glycoproteomics, the selectivity of interactions mediated by GAG chains, the display of GAG chains and PGs at the cell surface and their impact on the availability and activity of soluble ligands, and on their move through the glycocalyx layer to reach their receptors, the human GAG profile in health and disease, the roles of GAGs and particular PGs (syndecans, decorin, and biglycan) involved in cancer, inflammation, and fibrosis, the possible use of GAGs and PGs as disease biomarkers, and the design of inhibitors targeting GAG biosynthetic enzymes and GAG–protein interactions to develop novel therapeutic approaches.

Milk-derived extracellular vesicles (EVs) have various functions, including immune regulation and promoting intestinal development. These EVs have substantial potential for application in infant formula and functional foods development. In addition, numerous studies have shown that milk-derived EVs carry proteins, lipids, and nucleic acids away from their parental cells, acting as messengers between cells. Moreover, structural integrity and biological viability are necessary prerequisites for the functional and omics studies of milk-derived EVs. Therefore, selecting appropriate methods for isolating and characterizing milk-derived EVs is essential for subsequent studies. Accordingly, this review summarizes the isolation and characterization methods for milk-derived EVs and their biological functions and roles. Furthermore, it discusses the comprehensive application of isolation methods, providing a reference for research on and development of milk-derived EVs.

IntroductionNon-alcoholic fatty liver disease (NAFLD) has become the leading cause of chronic liver disease worldwide. Hepatocellular carcinoma (HCC) is the fifth most common malignancy worldwide, with high morbidity and mortality. The rapidly increasing incidence of NAFLD is becoming an essential precursor of HCC globally. MicroRNAs (miRNAs) are involved in the progression of NAFLD and HCC.MethodPotential miRNAs associated with NAFLD in HCC tumorigenesis were identified through a systematic review, and their roles were evaluated by data mining analysis. The biological function of the potential miRNA and its target genes in NAFLD and HCC were evaluated by bioinformatic analysis.ResultMIR122 was identified as the potential miRNA associated with NAFLD and HCC. Then, MIR122 expression was significantly lower in HCC patients, and higher MIR122 levels were associated with significantly better overall survival. Next, the biological functions of MIR122 and target genes were predicted to be involved in inflammation, fibrosis, cell proliferation, invasion, metastasis, and apoptosis. In particular, the FOXO signaling pathway may regulate the above biological functions.ConclusionMIR122 was suggested to be involved in progressing from NAFLD to HCC through the PI3K/AKT/FOXO pathway.Systematic review registrationPROSPERO, identifier: CRD 42024517940.

Abstract FN-doped carbon dots were synthesized using powdered leaves of Moringa oleifera L./Chromolaena odorata L./Tridax procumbens L./Tinospora cordifolia L./ and Lantana camara L., along with a precursor called 4,5-difluoro-1,2-benzenediamine (DFBD) and compared against the drug zaltoprofen derived carbon dots. They were assessed for their optical and structural characteristics using photoluminescence (optimal emission λ of 600 nm), vibrational (FTIR) spectroscopy (characteristic wave numbers of 1156 and 1269 cm−1 for C–F), as well as X-ray diffraction (XRD) (highest intensity at 27.56°) and high-resolution transmission electron microscopy (HR-TEM) (particles in the size range of 15–20 nm). Further, field emission scanning electron microscopy (FESEM) / energy dispersive spectroscopy (EDX) indicated FN doping of oval/oblong carbon dots. Membrane protection in percent is found to be 55.3 and 80.4 for FN-CDs and Z-FN-CDs respectively. The DPPH-free radical scavenging activity by FN-CDs was 69.4%, while with Z-FN-CDs, it was 54.2%. When tested on six bacterial strains (three each for gram-positive and gram-negative), the FN-CDs displayed a halo (ZOI) between 9 and 19 mm, whereas the Z-FN-CDs displayed a clearance zone between 9 and 17 mm. The FN-CDs showed significant emission-red-shift effects and demonstrated concentration-dependent biocompatibility and viability in neuroblastoma and beta-TC6-cell lines.

Abstract Biomaterials with exceptional performance are crucial for addressing the challenges of complex bone regeneration. Compared with traditional three‐dimensional scaffolds, injectable microspheres enable new strategies for the treatment of irregular bone defects. Biodegradable poly (lactic‐co‐glycolic acid) has found widespread applications as microcarriers of drugs, proteins, and other active macromolecules. Applied to the surface of poly (lactic‐co‐glycolic acid) cage‐like structures (PLGA‐CAS), hydroxyapatite (HA) effectively reduces inflammation while enhancing biological effects. In this study, we loaded the surface of PLGA‐CAS with micro‐ and nano‐hydroxyapatite particles, referred to as μHA/PLGA‐CAS and nHA/PLGA‐CAS, respectively. Subsequently, their material characteristics and biological effects were assessed. The incorporation of hydroxyapatite onto PLGA‐CAS resulted in enhanced surface roughness and hydrophilicity, coupled with improved thermal stability and delayed degradation. Furthermore, μHA/PLGA‐CAS induced osteogenic differentiation of osteoblast precursor cells, while nHA/PLGA‐CAS improved endothelial cell adhesion and stimulated angiogenic differentiation in vitro. Collectively, these findings suggest that μHA/PLGA‐CAS and nHA/PLGA‐CAS, each with distinct characteristics, hold significant potential for application as microcarriers in various biomedical contexts.

Abstract UHRF1 as a member of RING-finger type E3 ubiquitin ligases family, is an epigenetic regulator with five structural domains. It has been involved in the regulation of a series of biological functions, such as DNA replication, DNA methylation, and DNA damage repair. Additionally, aberrant overexpression of UHRF1 has been observed in over ten cancer types, indicating that UHRF1 is a typical oncogene. The overexpression of UHRF1 repressed the transcription of such tumor-suppressor genes as CDKN2A, BRCA1, and CDH1 through DNMT1-mediated DNA methylation. In addition to the upstream transcription factors regulating gene transcription, post-translational modifications (PTMs) also contribute to abnormal overexpression of UHRF1 in cancerous tissues. The types of PTM include phosphorylation, acetylation, methylationand ubiquitination, which regulate protein stability, histone methyltransferase activity, intracellular localization and the interaction with binding partners. Recently, several novel PTM types of UHRF1 have been reported, but the detailed mechanisms remain unclear. This comprehensive review summarized the types of UHRF1 PTMs, as well as their biological functions. A deep understanding of these crucial mechanisms of UHRF1 is pivotal for the development of novel UHRF1-targeted anti-cancer therapeutic strategies in the future.

Family with sequence similarity 20 C (FAM20C) is a Golgi protein kinase that phosphorylates the serine residue in the S-x-E/pS motif of target proteins. FAM20C phosphorylates most secreted proteins, which play important roles in multiple biological processes, including cancer progression, biomineralization, and lipid homeostasis. Numerous studies have documented the potential contribution of FAM20C to the growth, invasion, and metastasis of glioma, breast cancer, and other cancers, as well as to the mineralization process of teeth and bone. In addition, FAM20C has been found to be associated with the occurrence and development of certain cardiovascular diseases and endocrine metabolism disorders. It raises hopes that understanding the disease-specific mechanisms of FAM20C may hold the key to developing new strategies for these diseases. This review comprehensively covers the existing literature to provide a summary of the structure and biological functions of FAM20C, with a particular focus on its roles in the disease context.

Background: Significant progress has been achieved in the management of multiple myeloma (MM) by implementing high-dose therapy and stem cell transplantation. Moreover, the prognosis of patients has been enhanced due to the introduction of novel immunomodulatory drugs and the emergence of new targeted therapies. However, predicting the survival rates of patients with multiple myeloma is still tricky. According to recent researches, platelets have a significant impact in affecting the biological activity of tumors and are essential parts of the tumor microenvironment. Nonetheless, it is still unclear how plateletrelated genes (PRGs) connect to the prognosis of multiple myeloma. Methods: We analyzed the expression of platelet-related genes and their prognostic value in multiple myeloma patients in this study. We also created a nomogram combining clinical metrics. Furthermore, we investigated disparities in the biological characteristics, immunological microenvironment, and reaction to immunotherapy, along with analyzing the drug susceptibility within diverse risk groups. Results: By using the platelet-related risk model, we were able to predict patients' prognosismore accurately. Subjects in the high-risk cohort exhibited inferior survival outcomes, both in the training and validation datasets, as compared to those in the low-risk cohort (p < 0.05). Moreover, there were differences in the immunological microenvironments, biological processes, clinical features, and chemotherapeutic drug sensitivity between the groups at high and low risk. Using multivariable Cox regression analyses, plateletrelated risk score was shown to be an independent prognostic influence inMM (p < 0.001, hazard ratio (HR) = 2.001%, 95% confidence interval (CI): 1.467-2.730). Furthermore, the capacity to predict survival was further improved when a combined nomogram was utilized. In training cohort, this outperformed the predictive value of International staging system (ISS) alone from a 5-years area under curve (AUC) = 0.668 (95%CI: 0.611-0.725) to an AUC = 0.721 (95% CI: 0.665-0.778). Conclusion: Our study revealed the potential benefits of PRGs in terms of survival prognosis of MM patients. Furthermore, we verified its potential as a drug target for MM patients. These findings open up novel possibilities for prognostic evaluation and treatment choices for MM. [ABSTRACT FROM AUTHOR]

Extracellular vesicles (EVs) are nano-sized particles involved in intercellular communications that intrinsically possess many attributes as a modern drug delivery platform. Haematococcus pluvialis-derived EVs (HpEVs) can be potentially exploited as a high-value-added bioproduct during astaxanthin production. The encapsulation of HpEV cargo is a crucial key for the determination of their biological functions and therapeutic potentials. However, little is known about the composition of HpEVs, limiting insights into their biological properties and application characteristics. This study examined the protein composition of HpEVs from three growth phases of H. pluvialis grown under high light (350 µmol·m−2·s−1) and sodium acetate (45 mM) stresses. A total of 2038 proteins were identified, the majority of which were associated with biological processes including signal transduction, cell proliferation, cell metabolism, and the cell response to stress. Comparative analysis indicated that H. pluvialis cells sort variant proteins into HpEVs at different physiological states. It was revealed that HpEVs from the early growth stage of H. pluvialis contain more proteins associated with cellular functions involved in primary metabolite, cell division, and cellular energy metabolism, while HpEVs from the late growth stage of H. pluvialis were enriched in proteins involved in cell wall synthesis and secondary metabolism. This is the first study to report and compare the protein composition of HpEVs from different growth stages of H. pluvialis, providing important information on the development and production of functional microalgal-derived EVs.
