It is expressed in various tissues, mainly in nociceptive neurons, adipocytes, and other cell types. This channel is involved in pain and temperature transition processes, although it has recently been implicated in adipocyte browning processes. That is why the study of this receptor has increased in recent years to understand the process of activation and inactivation by various stimuli. In this work, we focus on modeling a complete channel of human TRPV1 (hTRPV1), the structural changes, and especially the behavior of the pore when this protein is subjected to high temperatures (400 K). We report that when molecular dynamics simulate hTRPV1 at 400 K, it suffers an increase in the diameter of the two gates reported elsewhere in the pore, suggesting the opening of the channel. In this work, we describe the structural changes in the entire protein, concomitant to those in the pore, favoring this process, which might be associated with its biological activity.","PeriodicalId":19025,"journal":{"name":"Molecular Biology Research Communications","volume":"15 1","pages":"39-48"},"PeriodicalIF":1.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12673628/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145677711","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Given the importance of autophagy and UPR (Unfolding Protein Response) in chemotherapy resistance, as well as the role of Beclin-1, LC3IIβ, and P62 in the regulation of autophagy, we evaluated the effect of TMZ along with CPUK02 on U87 cells as a model of Glioblastoma cancer in this study. To achieve this goal, we treated the U87 cells with different doses of TMZ (50, 100, 200, 400, and 800 μM) and CPUK02 (1, 0.5, 0.25, 0.125, 0.06, 0.03, 0.01, and 0.007 μM); then, cell viability was assessed by MTT assay. The gene expression of Beclin1, P62, LC3IIβ, and XBP-1s was analyzed using quantitative real-time polymerase chain reaction. The comparison of the control group with the groups treated with the TMZ drug showed that, in 48 and 72 hours, doses of TMZ more than IC50 (100 μM) (p<0.001) significantly led to cell death. CPUK02 doses more than 0.125 (p<0.0001) significantly led to cell death. TMZ and CPUK02 combination therapy (100 and 0.03 μM, respectively) increased the expression of Beclin-1, LC3IIβ, and P62 and activated the IRE-1 arm of UPR by increasing the expression of XBP-1s. TMZ and CPUK02 treatment inhibits the autophagic flux (p62, LC3IIβ). Increased XBP-1s expression might contribute to the enhanced TMZ sensitivity. This combination therapy is promising for TMZ-resistant cancers, but it needs further investigation.","PeriodicalId":19025,"journal":{"name":"Molecular Biology Research Communications","volume":"15 1","pages":"11-20"},"PeriodicalIF":1.0,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12673630/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145678261","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recent studies suggest that the unfolded protein response (UPR), particularly the inositol-requiring enzyme 1 (IRE1) signaling arm, plays a pivotal role in GBM pathophysiology by mediating cellular adaptation to endoplasmic reticulum stress. This systematic review evaluates the role of IRE1 in GBM cell lines (U87, U251) and investigates whether its activation or inhibition affects migration, proliferation, apoptosis, and cell death. A comprehensive search was conducted on PubMed/ Medline, Scopus, Web of Science, and Embase using various keywords up to October 14, 2025, following the PRISMA guidelines. The search aimed to identify original English-language studies that specifically examined and analyzed the IRE1 arm of the UPR pathway in glioblastoma cells. Out of 466 records, 26 studies met the inclusion criteria. Twenty studies explored IRE1 activation, while six investigated its inhibition. IRE1 activation yielded dual effects-promoting apoptosis via JNK or XBP1 pathways in some contexts, while supporting tumor survival and angiogenesis through XBP1-mediated transcription and RIDD suppression in others. Dual role of IRE1 could sensitize GBM cells to chemotherapy agents, reduced migration and proliferation, and induced apoptosis. IRE1 acts as a context-dependent regulator in GBM, showing both pro-survival and pro-death roles. Most studies report that IRE1 activation promotes glioblastoma cell death, while fewer address its inhibition. Thus, both activation and inhibition may offer therapeutic potential depending on cellular context and downstream signaling.","PeriodicalId":19025,"journal":{"name":"Molecular Biology Research Communications","volume":"15 2","pages":"85-101"},"PeriodicalIF":1.4,"publicationDate":"2026-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13148453/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147840630","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several kinds of bioinformatics tools were employed to fulfill the study's objective. Gene hub analysis of 34284 genes was scanned. Six genes demonstrated high expression rates were expressed during the metastatic stage: CCL27, IL19, PAPPA2, UHRF1, IFNAR2, and GLS2. IFNAR2 and UHRF1 had the highest levels of expression. The expression of the COL4A4 gene rose in response to sun exposure, but the expression of the other genes remained same.
