The effective clinical application of the drug is very much limited by its adverse drug reactions on various tissues. Most importantly, Adriamycin causes cardiomyopathy, one of the life-threatening complications of the drug. Altered expression of PPARγ in adipocytes inhibited the glucose and fatty acids uptake by down regulating GLUT4 and CD36 expression and causes cardiotoxicity. Therefore, the influence of Adriamycin in cardiac ailments was investigated in vivo and in vitro. Adriamycin treated rats showed altered ECG profile, arrhythmic heartbeat with the elevated levels of CRP and LDH. Dysregulated lipid profiles with elevated levels of cholesterol and triglycerides were also observed. Possibilities of cardiac problems due to cardiomyopathy were analyzed through histopathology. Adriamycin treated rats showed no signs for atheromatous plaque formation in aorta but disorganized cardiomyocytes with myofibrillar loss and inflammation in heart tissue, indicative of cardiomyopathy. Reduced levels of antioxidant enzymes confirmed the incidence of oxidative stress. Adriamycin treatment significantly reduced glucose and insulin levels, creating energy demand due to decreased glucose and insulin levels with increased fatty acid accumulation, ultimately resulting in oxidative stress mediated cardiomyopathy. Since PPARs play a vital role in regulating oxidative stress, the effect of Adriamycin on PPARγ was analyzed by western blot. Adriamycin downregulated PPARγ in a dose-dependent manner in H9C2 cells in vitro. Overall, our study suggests that Adriamycin alters glucose and lipid metabolism via PPARγ inhibition that leads to oxidative stress and cardiomyopathy that necessitates a different therapeutic approach.</p>","PeriodicalId":15151,"journal":{"name":"Journal of Biochemical and Molecular Toxicology","volume":"38 10","pages":""},"PeriodicalIF":3.2,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142328448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty-five <i>Sprague-Dawley</i> male rats were divided into five groups: Control, Sodium arsenite (SA), CRV, SA + CRV25, and SA + CRV50. Sodium arsenite was administered via oral gavage at a dose of 10 mg/kg for 14 days, and 30 min later, CRV 25 or 50 mg/kg was administered via oral gavage. Oxidative stress, inflammation, apoptosis, autophagy damage pathways parameters, and liver tissue integrity were analyzed using biochemical, molecular, western blot, histological, and immunohistological methods. Carvacrol decreased sodium arsenite-induced oxidative stress by suppressing malondialdehyde levels and increasing superoxide dismutase, catalase, glutathione peroxidase activities, and glutathione levels. Carvacrol reduced inflammation damage by reducing sodium arsenite-induced increased levels of NF-κB and the cytokines (TNF-α, IL-1β, IL-6, RAGE, and NLRP3) it stimulates. Carvacrol also reduced sodium arsenite-induced autophagic (Beclin-1, LC3A, and LC3B) and apoptotic (P53, Apaf-1, Casp-3, Casp-6, Casp-9, and Bax) parameters. Carvacrol preserved sodium arsenite-induced impaired liver tissue structure.

The present study investigates the effects of a sub-acute (28 days) exposure to BPA (10, 50 and 100 mg/kg/day) in adult male mice on various hormones levels, sperm motility, sperm count, functional integrity of sperm plasma membrane, testicular histological changes, oxidative stress markers and DNA damage. The key proteome signatures were quantified by LC-MS/MS analysis using Orbitrap Fusion Lumos Tribrid Mass Spectrometer equipped with nano-LC Easy-nLC 1200.

Specifically searched male reproductive function related proteins suggested a complex network where 46 potential proteins regulating spermatogenesis, sperm structure, activity and membrane integrity while tackling oxidative stress responses were downregulated.

USP1 could increase the stability of KDM1A via deubiquitination, and USP1 depletion restrained the progression of TNBC cells through decreasing KDM1A expression.
