Overview

Preclinical study reveals circ_0001112 downregulation promotes cardiomyocyte apoptosis in myocardial infarction models, suggesting a therapeutic role for the miR-324-5p/CDK6 pathway.

Key Points

To investigate the biological role and regulatory mechanism of circular RNA circ_0001112 in myocardial infarction and hypoxia-induced cardiomyocyte apoptosis.
Assessed circ_0001112 expression patterns in a myocardial infarction model and hypoxia-treated cardiomyocytes.
Conducted dual-luciferase reporter assays and Ago2-miRNP immunoprecipitation to identify and confirm direct interactions among circ_0001112, miR-324-5p, and the 3'UTR of CDK6.
Evaluated cardiomyocyte apoptosis following functional modulation of circ_0001112, miR-324-5p, and CDK6 under hypoxic conditions.
Circ_0001112 was significantly upregulated in myocardial infarction models and hypoxia-exposed cardiomyocytes, and its overexpression suppressed hypoxia-induced apoptosis.
Circ_0001112 functioned as a molecular sponge for miR-324-5p, which directly targeted the 3'UTR of cyclin-dependent kinase 6 (CDK6).
Overexpression of miR-324-5p or knockdown of CDK6 significantly reversed the anti-apoptotic effects mediated by circ_0001112 overexpression.
