The study also analyzed myeloid cells and tumor-infiltrating lymphocytes (TILs) within the breast cancer immune microenvironment, identifying 14 TIL subpopulations and assessing their proportion variations across different patients. The CellChat tool revealed a complex cellular communication network within the tumor microenvironment, showing notable differences in communication intensity and patterns between TNBC and NTNBC patients. Additionally, the key regulatory role of the senescence-associated gene MDH1 in breast cancer was confirmed, and its impact on drug sensitivity was explored. Finally, it was discovered that the phytosterol Schottenol inhibits breast cancer cell proliferation by downregulating MDH1 expression and enhances sensitivity to paclitaxel. These findings provide new insights into MDH1 as a therapeutic target and suggest Schottenol as a potential strategy to overcome breast cancer drug resistance.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"127 ","pages":"Article 111608"},"PeriodicalIF":4.4,"publicationDate":"2025-01-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143001000","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}

A 70 % partial hepatectomy (PHx) model was established in Aqp5<sup>−/−</sup> mice to evaluate the pathological changes in the liver. Reactive oxygen species (ROS) production was assessed using a dichlorodihydrofluorescein diacetate (DCFH-DA) assay. Aqp5 deficiency significantly increased ROS production, the number of TUNEL-positive cells, and disrupted mitochondrial membrane potential in the liver of Aqp5-deficient mice. The impact of Aqp5 on ROS/NLRP3/Gasdermin-D (GSDMD)-mediated pyroptosis was examined through the administration of <em>N</em>-acetyl-L-cysteine (NAC, an ROS scavenger) or disulfiram (DSF, a GSDMD inhibitor). In Aqp5-deficient mice, the regenerative liver exhibited increased expression of NLRP3, enhanced activation of caspase-1 and GSDMD, as well as elevated secretion of IL-1β. Treatment with DSF significantly attenuated GSDMD-mediated pyroptosis triggered by Aqp5 deficiency in the regenerating liver. Furthermore, the administration of NAC to Aqp5-deficient mice resulted in a reduction in the expression levels of NLRP3, the activity levels of caspase-1 and GSDMD, as well as the release of IL-1β. Our findings indicate that the deficiency of Aqp5 facilitates GSDMD activation through the production of ROS.

This study investigated the reno-protective effects of dulaglutide, a glucagon-like peptide-1 receptor agonist (GLP-1 RA) widely used in the management of diabetes, and aimed to elucidate its underlying mechanisms. Mice with db/db and db/m genotypes were allocated into four experimental groups and treated with either dulaglutide or a saline control for 10 weeks. Following the treatment period, biological samples were collected for comprehensive analysis. Serum and urinary creatinine levels were measured using a creatinine assay, while urinary protein concentrations were quantified via ELISA. Histopathological kidney damage was assessed through hematoxylin and eosin (HE) staining, with glomerular lesions evaluated using periodic acid-Schiff (PAS) staining. Inflammatory markers, ferroptosis-related indicators, and fibrosis in kidney tissues were further analyzed through PCR, Western blot (WB), immunohistochemistry (IHC), and transmission electron microscopy (TEM). Consistent with prior findings, this research demonstrated that dulaglutide improves renal function and mitigates pathological kidney damage in db/db mice. Treatment with dulaglutide significantly reduced mRNA expression of ferroptosis-related markers, including ACSL4, SLC7A11, and Ptgs2, alongside a decrease in 4-HNE levels in kidney tissues. Furthermore, dulaglutide downregulated ACSL4 protein levels and upregulated GPX4 protein expression, thereby ameliorating mitochondrial damage in renal tubular cells. In addition to these effects, dulaglutide alleviated kidney inflammation and fibrosis in db/db mice, with concomitant suppression of P-STAT3 and P-ERK expression. Collectively, these findings underscore dulaglutide's reno-protective effects in DKD, mediated through the inhibition of inflammation, improvement in renal fibrosis and ferroptosis, and modulation of P-STAT3 and P-ERK signaling pathways.</div></div>","PeriodicalId":9902,"journal":{"name":"Cellular signalling","volume":"127 ","pages":"Article 111603"},"PeriodicalIF":4.4,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142977881","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}

Silencing NSD2 or FOLR1 inhibited the proliferation and migration of pulmonary artery endothelial cells (PAECs) and alleviated PAH phenotypes, right ventricular dysfunction, and pulmonary artery remodeling.

Furthermore, NSD2 or FOLR1 silencing decreased the expression of key glycolytic genes (HK2, TIGAR, and G6PD) by suppressing their promoter activity and weakening the interaction between FOLR1/H3K36me2 and these gene promoters.

Furthermore, we demonstrate that overexpression of SEPT5 promotes proliferation of ccRCC cells, alters their cell cycle distribution, and enhances their migratory and invasive capabilities. Additionally, we observe a positive correlation between SEPT5 overexpression and resistance to sorafenib and sunitinib in ccRCC cells. Further mechanistic investigations have revealed that SEPT5 serves as a novel direct transcriptional target of HIF-1α, leading to subsequent reduction in protein expression and nuclear translocation of HIF-1α. This establishes a feedback loop in ccRCC tumorigenesis. Ultimately, knockdown of SEPT5 significantly inhibits xenografted tumor growth in vivo.

However, there are currently few studies on the mechanism of differentiation of OS, which puts the development of differentiation therapeutic drugs into a bottleneck. Substrate stiffness can regulate differentiation in mesenchymal stem cells. Evidence supports that mesenchymal stem cells and osteoblast precursors are the origin of OS. In this study, we simulated different stiffnesses in vitro to investigate the mechanism of substrate stiffness affecting differentiation of OS. We demonstrate that Piezo type mechanosensitive ion channel component 1 (PIEZO1) plays a critical regulatory role in sensing substrate stiffness in osteogenic and adipogenic differentiation of OS. When OS cells are cultured on the stiff substrate, integrin subunit beta 1 (ITGB1) increases and cooperates with PIEZO1 to promote Yes-Associated Protein (YAP) entering the nucleus, and may inhibit EZH2, thereby inhibiting H3K27me3 and increasing RUNX2 expression, and cells differentiate toward osteogenesis.
