It is defined as the detrimental effects of exposure to (excessive) amounts of toxic lipid species, leading to increased mitochondrial \u03b2\u2010oxidation, oxidative stress (OxS), and organellar dysfunction. Carvedilol (CV) is a \u03b2\u2010adrenergic blocker with antioxidant properties. To elucidate whether CV protects hepatocytes against lipotoxicity induced by palmitic acid (PA) by reducing OxS and endoplasmic reticulum (ER) stress. Primary rat hepatocytes (rHep) were used. Lipotoxicity was induced by PA (1\u2009mmol\/L). Cell damage was evaluated by Sytox Green staining. Mitochondrial generation of reactive oxygen species (mROS) was assessed by MitoSox. mRNA and protein expression were measured by qPCR and Western blot, respectively. Lipid accumulation was measured by Oil Red O staining and triglyceride (TG) content. PA induced cell death in &gt;\u200980% of cells and increased mROS generation. PA increased mRNA expression of ER stress markers CHOP and sXBP1 and slightly increased lipid accumulation. Expression of the \u03b2\u2010oxidation\u2010related gene Cpt1a was increased. CV (10\u2009\u00b5mol\/L) significantly reduced PA\u2010induced cell death to control levels (&lt;\u20098% of total cells), and mROS generation and expression of the mitochondrial antioxidant enzymes Sod2 and Cat were increased by 40% by CV in the presence of PA. CV did not change the expression of ER stress markers. CV, added before PA, protects rHep against PA\u2010induced cytotoxicity by reducing OxS and increasing the expression of antioxidant enzymes without any additional protective effect on ER stress or lipid accumulation.<\/jats:p>","DOI":"10.1002\/cbf.70057","type":"journal-article","created":{"date-parts":[[2025,2,11]],"date-time":"2025-02-11T01:01:43Z","timestamp":1739235703000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Protective Effect of Carvedilol Against Oxidative Stress Induced by Palmitic Acid in Primary Rat Hepatocytes"],"prefix":"10.1002","volume":"43","author":[{"given":"Sandra A.
