However, whether Rha can lessen Cis resistance in tongue squamous cell carcinoma (TSCC) by mediating HIF-1α activity is unclear. Cis-resistant SCC9 (SCC9-CisR) cells were treated with Cis, Rha, or Cis plus Rha to explore the effect of Rha on Cis resistance using a cell counting kit-8, flow cytometry, and tumor sphere formation assays. Stemness markers CD44 and SOX2 and HIF-1α mRNA levels were detected by quantitative PCR. The GSE115119 database and plugin iRegulon were employed to select target genes mediated by HIF-1α. Protein levels of HIF-1α, monocarboxylate transporter 4 (MCT4), and the Wnt/β-catenin pathway were measured by western blot. Subcutaneous xenograft models were constructed to explore the efficacy of Rha in combating Cis resistance. Rha repressed the growth and stemness of SCC9-CisR cells in vitro and in vivo. HIF-1α protein levels were markedly elevated in SCC9-CisR cells, yet Rha treatment attenuated the transcriptional activity of HIF-1α but not HIF-1α mRNA levels. Rha plus Cis repressed the viability and stemness of SCC9-CisR cells, but not HIF-1α-knockdown SCC9-CisR cells, compared with Cis alone. Rha-induced stemness inhibition and apoptosis in SCC9-CisR cells were overridden after HIF-1α overexpression. Rha inhibited the Wnt/β-catenin signaling by regulating the HIF-1α/MCT4 axis. In conclusion, Rha reduced cell stemness and enhanced Cis sensitivity in TSCC, which was achieved possibly via suppressing the Wnt/β-catenin signaling through mediation of the HIF-1α/MCT4 axis.</p>","PeriodicalId":94244,"journal":{"name":"The Kaohsiung journal of medical sciences","volume":" ","pages":"e70069"},"PeriodicalIF":0.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144562452","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}

This study compares hypoxia and normoxia WJ-MSCs in a CCl<sub>4</sub>-induced liver fibrosis rat model. Sprague-Dawley rats received chronic CCl<sub>4</sub> to induce fibrosis. At Week 8, normoxia or hypoxia WJ-MSCs were injected via the portal vein.

Fibrosis regression was evaluated via ultrasound, histology, and collagen quantification. Regeneration was analyzed through Ki67 immunostaining and qPCR for Ki67 and HGF. MSC engraftment was determined by hNA immunohistochemistry. Both normoxia and hypoxia WJ-MSCs improved liver function, with hypoxia WJ-MSCs showing greater AST and T-Bil reductions. PET/MR imaging demonstrated superior metabolic recovery in the hypoxia group, with greater <sup>18</sup>F-FDG uptake reduction. Histological analysis confirmed more significant fibrosis regression and collagen reduction in the hypoxia group. Gene expression analysis showed stronger suppression of TGF-β, α-SMA, and collagen I. Liver regeneration markers Ki67 and HGF were significantly upregulated with a greater HGF increase in the hypoxia group. Additionally, hypoxia WJ-MSCs exhibited higher engraftment and reduced pulmonary entrapment, indicating improved liver homing.

Through bioinformatics analysis, the UC-related differentially expressed genes were predicted using the GSE38713 database and intersected with the lists of ASI targets and transcription factors, and the protein-protein network was constructed to screen the key target transcription factors. ASI inhibited the shortening of colon length, reduced histological damage scores, ameliorated pathology, and the overproduction of pro-inflammatory cytokines. After ASI treatment, DSS-stimulated human NCM460 cells showed increased cell viability, decreased levels of pro-inflammatory cytokines and cleaved-Caspase-3, and enhanced ZO-1 and claudin-3 expression. WDR5 was a target of ASI in UC, and overexpression of WDR5 compromised the effects of ASI.

This study investigates the potential mechanisms by which morroniside ameliorates diabetic osteoporosis (DOP). In vivo experiments were conducted to evaluate biochemical parameters in rats under different treatment conditions. Bone tissues underwent HE staining, and bone mineral density (BMD) along with key bone metabolism markers (β-CTX, OC, SOST) were measured. The activities of antioxidant enzymes (SOD, GPX, CAT), oxidative stress indicators (MDA), and levels of inflammatory factors (MCP-1, IL-6, IL-1, TNF-α) were also assessed. Western blot was used to analyze the expression of proteins associated with AGE/RAGE signaling and the Wnt/β-catenin pathway. Morroniside increased trabecular bone quantity and quality, upregulated the bone formation markers OC and SOST, downregulated the bone resorption marker β-CTX, and significantly increased BMD. Additionally, it modulated the systemic metabolic status by reducing fasting blood glucose (FBG), glycated hemoglobin (HbA1c), free fatty acids (FFA), triglycerides (TG), and total cholesterol (TC). Further research indicated that morroniside inhibited AGE/RAGE signaling, mitigated oxidative stress and inflammatory responses, and enhanced Wnt/β-catenin pathway activity, thereby promoting osteoblast proliferation, differentiation, and mineralization. The introduction of DKK1 significantly attenuated these beneficial effects of morroniside, confirming its protective role through activation of the Wnt/β-catenin pathway. Morroniside exerts beneficial effects on bone metabolism and quality in DOP rats by regulating the AGEs/RAGE/Wnt/β-catenin signaling pathway, while also alleviating oxidative stress and inflammatory responses. These findings provide novel insights and potential therapeutic targets for the treatment of DOP.</p>","PeriodicalId":94244,"journal":{"name":"The Kaohsiung journal of medical sciences","volume":" ","pages":"e70063"},"PeriodicalIF":0.0,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144510193","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}
