YB1 dephosphorylation attenuates atherosclerosis by promoting CCL2 mRNA decay

Y-box binding protein 1 (YB1) is an RNA binding protein (RBP) that has been reported to play important roles in inflammation and atherosclerotic plaque formation. To explore the molecular mechanism of phosphorylated YB1 (pYB1) in atherosclerosis <em>in vitro</em>, we constructed YB1 phosphorylation site (Ser-100) mutant stable smooth muscle cell line (3ds-V5) and performed RNA profile screening through RNA-seq. We found inflammatory pathways and CCL2 was significantly decreased in the 3dS-V5 YB1 mutant compared with the control group (YB1-V5).
