Hsa-circ-ACSL1 Enhances Apoptosis and Autophagy in Myocarditis Cardiomyocytes Through the miR-7-5p/XBP1 Axis.

Background: Viral myocarditis (VMC) is a common cardiovascular disease, and circular RNAs (circRNAs) have been identified to play an important role in the pathophysiology of cardiovascular disease. However, the clinical significance, biological functions, and regulatory mechanisms of circRNAs in VMC remain poorly understood. Therefore, this study explored the biological functions and regulatory mechanisms of circ-ACSL1 in VMC.
