Abstract
This meta-analysis aimed to investigate the diagnostic value of blood circular RNA (circRNA) in atherosclerotic cardiovascular diseases (AS). Using bioinformatics and evidence-based medicine, we identified circ_0001900 as a potential biomarker for diagnosing AS-related cardiovascular diseases. Bioinformatics analysis indicated that circ_0001900 may participate in AS progression by regulating lipid and atherosclerosis-related genes on the MAPK1/3, SRC, TRAF6, and STAT3 signaling pathways. In vivo results showed that circ_0001900 was significantly up-regulated in AS mouse and AS patients' peripheral blood (PB), serum, serum serum extracellular vesicles (EVs), and peripheral blood mononuclear cells (PBMCs), with good diagnostic efficacy as evaluated by ROC curve analysis. Circ_0001900 knockout inhibited AS progression, which may be related to the regulation of these signaling pathways. These findings suggest that circ_0001900 may serve as a potential diagnostic and therapeutic target for AS-related cardiovascular diseases.
