Statin-sensitive dysregulated AT1 receptor function and density in hypercholesterolemic men.

abstract：BACKGROUND:Adriamycin (ADR) is an anticancer drug known to cause severe cardiac toxicity by generating free radicals. We investigated the role of a redox-regulating molecule, thioredoxin-1 (TRX1), in ADR-induced cardiotoxicity. METHODS AND RESULTS:The in vitro study showed that TRX1 was dose-dependently increased conc...
