It is essential to maintain the structural integrity and functionality of these tissues, and plays a significant role in wound healing, often found alongside collagen type I. Despite being the second most abundant collagen in human tissues after type I, its biological functions on various skin properties have not been thoroughly studied. In this study, we have isolated and developed an effective recombinant protein derived from human collagen type III alpha 1 chain (hCOL3A1). Our findings demonstrate that the recombinant proteins hCOL3A1-THR-M1 and M4 stimulate cell proliferation and collagen biosynthesis in human dermal fibroblasts (HDFs), and enhance wound healing. Notably, hCOL3A1-THR-M1 (referred to as HUCOLLATIN3) specifically penetrates both the epidermal and dermal layers in a full-thickness skin model. These results collectively indicate that hCOL3A1-THR-M1 holds promise as a potential biomaterial to prevent skin aging.","PeriodicalId":9010,"journal":{"name":"BMB Reports","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142103979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

During cell differentiation, profound changes occur in gene expression, chromatin organization, and nuclear morphology. This review explores the intricate relationship between nuclear architecture and cellular function, focusing on the roles of the nuclear lamina, nuclear pore complexes (NPCs), sub-nuclear bodies, and the nuclear scaffold. These components collectively maintain nuclear integrity, organize chromatin, and interact with key regulatory factors. The dynamic remodeling of chromatin, its interactions with nuclear structures, and epigenetic modifications work in concert to modulate gene accessibility and ensure precise spatiotemporal control of gene expression. The nuclear lamina stabilizes nuclear shape and is associated with inactive chromatin regions, while NPCs facilitate selective transport. Sub-nuclear bodies contribute to genome organization and gene regulation, often by influencing RNA processing. The nuclear scaffold provides structural support, impacting 3D genome organization, which is crucial for proper gene expression during differentiation. This review underscores the significance of nuclear architecture in regulating gene expression and guiding cell differentiation. Further investigation into nuclear structure and 3D genome organization will deepen our understanding of the mechanisms governing cell fate determination.","PeriodicalId":9010,"journal":{"name":"BMB Reports","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142104040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

HCC occurs people with chronic liver diseases. The purinergic receptor P2X 7 (P2RX7) is involved in tumor proliferation and growth. Also, P2RX7 is associated with tumor invasion and metastatic dissemination. High glucose utilization is important for the survival of various types of tumors. However, the role of P2RX7 in glucose metabolism and cellular survival of HCC remains unclear. Here, our results show that the gene and protein levels of P2RX7 were elevated in tumor cells of patients with HCC. The pharmacological inhibition of P2RX7 by A-804598, a selective P2RX7 antagonist, and genetic inhibition by P2RX7 knockdown suppressed the glycolytic activity by reduction of hexokinase 2 (HK2), a key enzyme of the glycolysis pathway, in human HCC cells. Also, both A-804598 treatment and P2RX7 knockdown induced cytotoxicity via inhibition of AKT activation which is critical for tumor cell survival in human HCC cells. Moreover, A-804598 treatment and P2RX7 knockdown increased cytotoxicity and caspase-3 activation in human HCC cells. These results suggest that inhibition of P2RX7 contributes to cytotoxicity by suppression of glycolysis and AKT activation in human HCC.","PeriodicalId":9010,"journal":{"name":"BMB Reports","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-09-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142104039","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To date, the role of ANGPTL4 in cancer growth and progression, and metastasis, has been variable. Accumulating evidence suggests that proteolytic processing and posttranslational modifications of ANGPTL4 can significantly alter its function, and may contribute to the multiple and conflicting roles of ANGPTL4 in a tissue-dependent manner. With the growing interest in ANGPTL4 in cancer diagnosis and therapy, we aim to provide an up-to-date review of the implications of ANGPTL4 as a biomarker/oncogene in cancer metabolism, metastasis, and the tumor microenvironment (TME). In cancer cells, ANGPTL4 plays an important role in regulating metabolism by altering intracellular glucose, lipid, and amino acid metabolism. We also highlight the knowledge gaps and future prospect of ANGPTL4 in lymphatic metastasis and perineural invasion through various signaling pathways, underscoring its importance in cancer progression and prognosis. Through this review, a better understanding of the role of ANGPTL4 in cancer progression within the TME will provide new insights into other aspects of tumorigenesis and the potential therapeutic value of ANGPTL4.

Despite this, the precise molecular mechanisms driving this pathological progression largely remain elusive. Our study unveils a pivotal role for the microRNA miR-328-5p in dampening endothelial inflammation by modulating the stability of JUNB (JunB proto-oncogene). Perturbation of miR-328-5p levels results in heightened monocyte adhesion to endothelial cells and enhanced transendothelial migration, while its overexpression mitigates these inflammatory processes. Furthermore, miR-328-5p hinders macrophage polarization toward the pro-inflammatory M1 phenotype, and exerts a negative influence on atherosclerotic plaque formation in vivo. By pinpointing JUNB as a direct miR-328-5p target, our research underscores the potential of miR-328-5p as a therapeutic target for inflammatory atherosclerosis. Reintroduction of JUNB effectively counteracts the anti-atherosclerotic effects of miR-328-5p, highlighting the promise of pharmacological miR-328-5p targeting in managing inflammatory atherosclerosis.
