Furthermore, three co-regulated genes associated with FCs were identified: GLRX, RNF13, and ABCA1. Among these genes, the roles of ABCA1 in the atherosclerotic process have been widely described, but many contradictory results have been presented, suggesting that the roles of ABCA1 in atherosclerosis need to be further explored. This evidence concerns the gene ABCA1 and atherosclerosis.
