Blockade of thromboxane A2 signaling attenuates ethanol-induced myocardial inflammatory response in mice.

ABSTRACT:

Background

Alcohol-associated cardiomyopathy (ACM) is a cardiac muscle disease characterized by inflammation and oxidative stress. Thromboxane-prostanoid receptor (TP-R) plays an important role in the pathogenesis of cardiovascular disease. Herein, we hypothesize that TP-R mediates alcohol-induced early cardiac injury.

Methods

Eight-week-old male C57BL/6 wild-type mice were fed a chronic ethanol (ET) or control diet (CON) for 10 days followed by a single binge of ethanol or maltose-dextrin through oral gavage. A cohort of ethanol-fed mice received SQ 29,548 (SQ), a TP-R antagonist. RNA sequencing, real-time PCR, and western blot analysis were performed on left ventricle to investigate alterations in genes and/or proteins mediating oxidative stress, inflammation, and cardiac
