Up to 33.6% of solid organ transplantation patients receiving Tac treatment develop hyperglycemia; however, the underlying mechanisms remain poorly understood. Here, using a mouse model of Tac-induced hyperglycemia, we found that Tac-induced body-weight loss, hyperglycemia, hypoinsulinemia, glucose intolerance and insulin resistance were improved by valsartan, a renin-angiotensin system (RAS) inhibitor. Histological and immunofluorescence analysis of the pancreas showed reduced islet areas and β-cell mass in Tac-treated mice. Moreover, when compared to control mice, isolated islets from Tac-treated mice showed a downregulation of cell-proliferation markers (Ki67, Ccna2 and Ccnd1) while an upregulation of apoptotic markers (DNA fragmentation, Bax and Caspase3). Tac also upregulated hypoxia-related markers in the pancreas, including hypoxia-inducible factor-1α (HIF-1α) and its downstream factors (Adm, Hmox1 and Vegfa), CD31 and pimonidazole adducts. Furthermore, treatment with Tac led to vascular dysfunction in pancreatic arteries. All of these adverse effects could be partially or fully abrogated by valsartan. Tac also increased levels of renin in renal tissue (1.00 ± 0.06 vs 1.29 ± 0.04, p < 0.05) and serum (28.35 ± 4.29 ng/mL vs 51.99 ± 4.95 ng/mL, p < 0.05). Inhibition of RAS by valsartan protected against Tac-induced vascular dysfunction in renal interlobar arteries. Collectively, our data illustrate a previously undescribed mechanism, in which Tac-induced vascular dysfunction in renal interlobar arteries leads to RAS activation. Blocking RAS by valsartan alleviates vascular dysfunction in dorsal pancreatic arteries and hypoxia in islets, which in turn prevents Tac-induced β-cell dysfunction and glucose metabolism disorder.</p>","PeriodicalId":18813,"journal":{"name":"Molecular Medicine","volume":"31 1","pages":"230"},"PeriodicalIF":6.0,"publicationDate":"2025-06-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12153204/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144266690","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to observe the dual therapeutic effects of DEH on DSS-induced ulcerative colitis (UC) and colorectal cancer (CRC), with a focus on exploring the molecular mechanism by which DEH exerts anti-inflammatory effect in inflammatory cells and induces autophagy in CRC cells. An inflammatory cell model was established by LPS/IFNγ-stimulated RAW264.7 macrophages to observe the anti-inflammatory effect of DEH, while colon cancer cell lines were used to observe the anticancer activity of DEH. DSS-induced mice and subcutaneous tumor model in nude mice were also established to observe the bidirectional regulation of DEH. This study demonstrates that low concentrations of DEH exhibit anti-inflammatory effects in vitro. Importantly, DEH achieves significant inhibition of IκBα degradation and phosphorylation levels, as well as subsequent NF-κB nuclear translocation, while also suppressing the phosphorylation of the MAPK family members JNK, ERK, and p38, by reducing elevated NOD2 expression induced by LPS/IFNγ. In addition, oral administration of DEH improves colitis and colonic barrier damage in DSS-induced mice. Interestingly, at a high concentration of DEH significantly activates the NOD2 signaling pathway to promote autophagy and apoptosis in CRC cells, contributing to its anti-CRC effect. These findings suggest that different concentration of DEH shows bidirectional regulation by improve inflammatory responses in UC and simultaneously possess anti-CRC effects by targeting the NOD2. This highlights DEH as a promising candidate for clinical treatment of UC and CRC.</p>","PeriodicalId":18813,"journal":{"name":"Molecular Medicine","volume":"31 1","pages":"221"},"PeriodicalIF":6.0,"publicationDate":"2025-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12139060/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144225987","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
