Shikonin attenuates sympathetic remodeling in chronic heart failure mice via regulating miR-124

Shikonin is a naphthoquinone compound extracted from the root of Lithospermum with various pharmacological activities. Sympathetic neural remodeling greatly contributes to chronic heart failure. Growing evidence has identified a critical role of microRNAs (miRNAs) in a variety of cardiac biological processes. This study aimed to verify whether shikonin could attenuate sympathetic neural remodeling and explore the possible regulatory role of...
