A cross-sectional study comparing the expression of DNA repair molecules in subjects with and without atherosclerotic plaques.

Background: Atherosclerosis, serving as the primary pathological mechanism at the core of cardiovascular disease, is now widely acknowledged to be associated with DNA damage and repair, contributing to atherosclerotic plaque formation. Therefore, molecules involved in the DNA repair process may play an important role in the progression of atherosclerosis. Our research endeavors to explore the contributions of specific and interrelated molecules involved in DNA repair (APE1, BRCA1, ERCC2, miR-221-3p, miR-145-5p, and miR-155-5p) to the development of atherosclerotic plaque and their interactions with each other.
