Structurally, TRIM7 features a conserved RBCC motif (RING, B-box, and coiled-coil domains) coupled with a variable C-terminal region that dictates the substrate specificity. In infectious contexts, TRIM7 is required for the pathogen-specific regulation, and exerts paradoxical effects by either promoting host defense or facilitating viral pathogenesis depending on pathogen type. Within oncology, TRIM7 manifests tumor-suppressive properties through regulating metastasis, apoptosis, and tumor immunology. In addition, it might serve as a reliable biomarker for monitoring the progression of idiopathic pulmonary fibrosis and also inhibits the progression of atherosclerosis. In summary, TRIM7 plays critical roles in different pathophysiological processes, and it might be a predictive and therapeutic target in certain human diseases.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"134 ","pages":"Article 111886"},"PeriodicalIF":4.4,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144149540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To further investigate PC's mechanistic role in RIBEs, proton microbeam radiation (MR) and partial radiation (PR) were used to arrange the co-culture bystander system. Key methodologies included siRNA-mediated PC formation modulation, inhibition of DNA damage response kinases ataxia telangiectasia-mutated gene (ATM), Ataxia telangiectasia and Rad3-related protein (ATR) or DNA-dependent protein kinase (DNApk), and quantitative analysis of γH2AX foci, cell proliferation, and reactive oxygen/nitrogen species (ROS/NO). The results showed that, firstly, PC inhibition in both PR and MR models significantly increased γH2AX foci formation and protein levels within 12 h while suppressing cell proliferation, which were reversed by TGF-β signaling inhibition. Secondly, although inhibition of ATM, ATR, or DNApk reduced γH2AX foci but resulted in decrease of proliferation rate. Scavenging ROS/NO similarly attenuated DNA damage but enhanced cell survival. Third, SMAD2/3 complex inhibition in PC-deficient bystander cells downregulated ATM/ATR expression and reduced intracellular NO/ROS levels. These results demonstrate that TGF-β1 drives RIBEs-associated DNA damage through canonical p-SMAD2/3 signaling, which amplifies ROS/NO production and hyperactivates ATM, ATR or DNApk.

Here, we showed that lactate significantly increased the cellular ATP content, activated succinate dehydrogenase activity, and enhanced oxygen consumption rate in pre-osteoblast MC3T3-E1 cells. Moreover, lactate treatment increased oxidative phosphorylation (OXPHOS) in parathyroid hormone (PTH)-treated MC3T3-E1 cells.
