This study investigates the role of Ring Finger Protein 216 (RNF216) in LUAD progression.MethodsRNF216 expression was evaluated in LUAD tissues and cells. Functional assays evaluated cell viability, migration, invasion, and ferroptosis in vitro. Mechanistic investigations defined RNF216's role in regulating p53 ubiquitination and stability. In vivo, xenograft models evaluated tumor growth and ferroptosis.ResultsRNF216 was markedly overexpressed in LUAD tissues and cell lines. Functional studies demonstrated that silencing RNF216 suppressed LUAD cell proliferation, migration, and invasion while inducing ferroptosis, characterized by increased reactive oxygen species (ROS), lipid peroxidation (LPO), and intracellular Fe2+ accumulation. Mechanistically, RNF216 knockdown stabilized p53 by reducing its ubiquitination, thereby promoting ferroptosis. These findings were corroborated in vivo, where RNF216 silencing significantly inhibited tumor growth and enhanced ferroptosis in xenograft models.ConclusionsOur results establish RNF216 as a pivotal oncogenic driver that accelerates LUAD progression by suppressing ferroptosis through p53 ubiquitination. Targeting RNF216 may represent a promising therapeutic strategy to induce ferroptosis and combat LUAD.","PeriodicalId":94029,"journal":{"name":"Human & experimental toxicology","volume":"44 ","pages":"9603271251336793"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144287651","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Twenty-two chemokines were quantitatively analyzed with three key findings: First, serum analysis revealed elevated levels of (i) CCL11, CCL17, CCL24, CCL27, and CXCL12 in 3×Tg-AD versus non-Tg mice; (ii) CCL22 in 2×Tg-AD versus non-Tg mice; and (iii) CCL5, CCL11, CCL17, CCL24, CCL27, and CXCL12 in 3×Tg-AD versus 2×Tg-AD mice. Second, hippocampal changes showed upregulation of CCL3/CCL12 in 2×Tg-AD and CXCL16 in 3×Tg-AD mice, with cortical alterations demonstrating distinct CCL3/CCL12/CCL4 increases in 2×Tg-AD versus elevated CCL1/CXCL13 in 3×Tg-AD mice. Third, Western blot confirmed enhanced hippocampal microglial activation specifically in 3×Tg-AD mice. ConclusionOur findings establish model-specific chemokine signatures that differentially engage neuroinflammatory pathways, suggesting that 3×Tg-AD mice may better replicate human AD's complex chemokine-glia interactions. This compartmentalized profiling provides a framework for targeting chemokine networks in model-specific therapeutic development and biomarker discovery.

However, the specific mechanism by which RIN regulates microglial activation and cerebral ischemia remains unexplored. This study aims to investigate the function and molecular pathways through which RIN activates the JAK2/STAT3 signaling cascade, promoting the transformation of microglial phenotypes that contribute to recovery from cerebral ischemic injury.Methods: By establishing a microglia oxygen glucose deprivation/reoxygenation (OGD/R) model and a middle cerebral artery occlusion animal model, we assessed changes in the expression of phenotype-specific marker factors for M1 and M2 microglia, as well as key proteins in the JAK2/STAT3 pathway, utilizing ELISA and Western blot techniques. Histological examination, including HE staining, TUNEL assay, and immunofluorescence, was employed to evaluate pathological changes in brain tissue, along with cell apoptosis and proliferation.Results: The results indicated that microglial activity was significantly reduced and shifted towards the M1 phenotype following OGD/R. However, RIN treatment reversed these changes. When JAK2/STAT3 inhibitors were combined with RIN, it inhibited RIN's protective effect. Animal studies have shown that RIN reduces histopathological changes associated with cerebral ischemia. Additionally, RIN inhibited microglial proliferation in ischemic cortical tissue and increased the expression of M2-type marker proteins, as well as the levels of phosphorylated JAK2 and STAT3 in the ischemic tissue.Conclusion: In conclusion, this study indicates that RIN may protect against cerebral ischemic injury by activating the JAK2/STAT3 pathway, which promotes the transition of microglia to the M2 phenotypic.","PeriodicalId":94029,"journal":{"name":"Human & experimental toxicology","volume":"44 ","pages":"9603271251324582"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143525592","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

ELISA was performed to detect OS-related factors and inflammatory cytokines. Reactive oxygen species (ROS) levels and pyroptosis were analyzed using DCFH-DA and TUNEL staining. LPS and ATP induced HTR-8/SVneo cells were co-transfected with sh-PRDX6/sh-KLF9 to explore the potential regulatory effect of KLF9 on PRDX6.ResultsLPS+ATP stimulation increased KLF9 expression in the PE cell model. Specifically, reducing KLF9 levels alleviated morphological damage and enhanced proliferation, migration, and invasion in the in vitro PE cell models. Moreover, inhibiting KLF9 expression decreased protein expression of NLRP3, GSDMD-N, cleaved caspase-1, and cleaved-IL-1β, suppressing cell death in LPS+ATP-induced HTR-8/SVneo cells. Analysis of OS indicators revealed that downregulating KLF9 expression restrained intracellular ROS production, decreased MDA expression, and increased SOD and CAT levels. KLF9 regulated the transcription of PRDX6 to attenuate OS and pyroptosis. Knockdown of PRDX6 partially abolished the effect of KLF9 downregulation on OS and pyroptosis of LPS+ATP-induced HTR-8/SVneo cells, as evidenced by the inhibition of cell proliferation, migration, and invasion, as well as the enhanced activity of the NLRP3 inflammasome.ConclusionDownregulation of KLF9 enhances trophoblast cell invasion and reduces OS and NLRP3 inflammasome activation-mediated pyroptosis.","PeriodicalId":94029,"journal":{"name":"Human & experimental toxicology","volume":"44 ","pages":"9603271251324702"},"PeriodicalIF":0.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
