Losartan protects human stem cell-derived cardiomyocytes from angiotensin II-induced alcoholic cardiotoxicity.

ABSTRACT: Alcoholic cardiomyopathy (ACM) is a myocardial injury caused by long-term heavy drinking. Existing evidence indicates that high levels of oxidative stress are the key to pathological cardiomyopathy caused by long-term exposure to high concentrations of alcohol, while angiotensin II (AngII) and its type 1 receptor (AT1R) play an important role in excessive drinking. Whether oxidative stress-induced damage in ACM is related to AngII and AT1R is unclear, and the effects of alcohol on the electrophysiology of myocardial cells have not been reported. Most existing studies have used animal models. This study established an in vitro model of ACM based on human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs). The transcriptional profiling of alcohol treatment was performed by RNA-
