BACKGROUND: The occurrence of thoracic aortic dissection (TAD) is closely related to the transformation vascular smooth muscle cells (VSMCs) from a contractile synthetic phenotype. role SGK1 (serum- and glucocorticoid-regulated kinase 1) in VSMC phenotypic TAD unclear. METHODS: Four-week-old male Sgk1 F/F ( floxed) ;Tagln Cre (smooth cell–specific knockout) mice were administered β-aminopropionitrile monofumarate for 4 weeks model TAD. inhibitor GSK650394 was daily via intraperitoneal injection treat mouse Immunopurification mass spectrometry used identify proteins that interact with SGK1. Immunoprecipitation, immunofluorescence colocalization, GST (glutathione S-transferase) pull-down detect molecular interactions between SIRT6 (sirtuin 6). RNA-sequencing analysis performed evaluate changes transcriptome. Quantitative chromatin immunoprecipitation determine target genes regulated by SIRT6. Functional experiments also conducted investigate SGK1-SIRT6-MMP9 (matrix metalloproteinase 9) transformation. effect regulation on evaluated human samples. RESULTS: or pharmacological blockade inhibited formation rupture monofumarate–induced TADs reduced degradation ECM (extracellular matrix) vessels. Mechanistically, promoted ubiquitination phosphorylating at Ser338, thereby reducing expression protein. Furthermore, transcriptionally inhibits MMP9 through epigenetic modification, forming regulatory axis, which participates signaling pathway. Additionally, our data showed lack SGK1-mediated inhibition partially dependent SIRT6-MMP9. CONCLUSIONS: These findings highlight key pathogenesis A regulating SIRT6-MMP9 providing insights into potential strategies treatment.

Chronic changes caused by a high-fat diet (HFD) may be associated with weakened lung function in obese patients. However, few studies have focused on the role of senescent cells HFD-induced pulmonary fibrosis. This study aimed to determine whether (i) obesity causes accumulation aging lungs, (ii) p16 epithelial or fibroblasts exacerbates long-term senescence-associated fibrosis (SAPF) and (iii) deletion clearance ameliorates SAPF through inactivation inflammasome metabolic remodelling.Twelve-month old male mice p16INK4a (hereafter p16) knockout (p16-- ) wild-type (WT), ApoE (ApoE-- ApoE-- p16-- were fed HFD induce obesity, effects treatment senolytic drug ABT263 SGK1 specific inhibitor EMD638683 fibrosis, inflammaging, gene expression, integrin-inflammasome signalling metabolism examined. A549 IMR-90 transduced p16-overexpressing adenovirus, treated palmitic oleic acids (P&O) steatosis vitro.We found that promoted expression increase lung. P16 alleviated secretory phenotype (SASP) HFD-fed mice, as well P&O-treated cells. RNA sequencing bioinformatics analyses revealed inhibited activation pathway cellular glycolysis. Mass spectrometry, co-immunoprecipitation GST pull-down assays demonstrated bound N-terminal SGK1, thereby interfering interaction between E3 ubiquitin ligase NEDD4L subsequently inhibiting K48-polyubiquitin-dependent degradation mediated NEDD4L-Ubch5 complex. was alleviate pathway.P16 integrin- cell glycolysis binding N- terminal intefering K48- polyubiquitin- dependent could used potential drugs treat

ABSTRACT Recent research has revealed a close association between obesity and various metabolic disorders, including renal diseases, but the mechanism is still unknown. This study explored role of p16INK4a in obesity‐related kidney fibrosis evaluated its potential as therapeutic target. Using wild‐type (WT) mice p16 KO mice, we fed both groups high‐fat diet (HFD) for 6 months. Our results showed that an HFD led to significant weight gain increased expression WT mouse kidneys. Notably, presented reduced fibrosis, indicated by decreased levels profibrotic proteins (α‐SMA collagen I) improved histological outcomes, glomeruli tubules. P16 also suppressed several proinflammatory biomarkers (MMP1, MMP3, IL‐1β, TNF‐α IL‐6) inhibited NLRP3 inflammasome pathway. The administration ABT263 further validated these findings decreasing inflammation HFD‐fed suggesting contributes fibrotic inflammatory processes. Metabolomic analyses knockout influenced pathways, linoleic acid pyrimidine metabolism, HFD‐induced Additionally, over‐expression was observed kidneys chronic disease patients with long‐term hyperlipidaemia. These highlight critical obesity‐induced damage suggest targeting may be promising approach treating inflammation.

Idiopathic pulmonary fibrosis (IPF) is characterized by fibrotic matrix deposition and irreversible aberrant tissue remodeling.Their mechanisms of action are associated with the activation macrophages a disturbed immune environment.We aim to determine how these activated influenced pathogenesis fibrosis.We found areas IPF patients contained more serum glucocorticoid-induced kinase 1 (SGK1)-positive M2-type macrophages.Similarly, bleomycin (BLM)+LPS significantly triggered high expression SGK1 in mice, accompanied destroyed lung structure function, increased markers microenvironment.Mechanistically, markedly promoted reprogramming lungs triggering glycogen synthase 3beta (GSK3β)-tat-interacting protein 60 (TIP60)-histone-3 lysine-27 acetylation (H3K27ac) signalings, which further released chemokine (C-C motif) ligand 9 (CCL9) attract Th17 cells delivered TGF-β fibroblasts for synergistically destroying microenvironment, was largely reversed macrophage depletion mice.We took as entry point deeply analyze provided insights development novel drugs represented SGK1.

The incidence of acute myocardial infarction (AMI) is increasing yearly. With the use thrombolysis or percutaneous coronary intervention (PCI), mortality rate has been significantly reduced. However, reperfusion can cause additional injury. There still a lack effective drugs to treat I/R injury, and it urgent find new therapeutic drugs.In this study, network pharmacology was used predict potential targets biological processes involved in Muscone-mediated treatment infarction. To model ischemia‒reperfusion hypoxia-reoxygenation vivo injury C57BL/6 mice constructed. Mice were treated with Muscone i.p. for 4 weeks. We detected cardiac function on day 28.The expression levels apoptotic proteins Caspase-3 Bax anti-apoptotic protein Bcl-2 by immunoblotting after AC16 cells vivo. Additionally, gene PUMA p53 analyzed qRT‒PCR. Molecular docking evaluate binding energy between NLRP3-related proteins. Immunoblotting qRT‒PCR assess NLRP3 signaling pathway-related (NLRP3, ASC, Caspase-1) gene, respectively. Moreover, extracellular acidification measured using Seahorse system glycolysis treatment. key glycolytic enzyme PKM2 Finally, ChIP‒qPCR performed determine histone modifications (H3K4me3, H3K27me3, H2AK119Ub) promoter region.GO functional enrichment analysis revealed that muscone regulating (BP) AMI, which mainly included negative regulation apoptosis pathway, response lipopolysaccharide, blood pressure regulation. cellular components (CC) muscone-mediated AMI lipid rafts, membrane microdomains, regions. molecular functions (MF) oxidoreductase activity, nuclear receptor transcription factor activity.
