IL1A and coronary artery disorder: The results demonstrated that the expression levels of three genes (DERL2, RCN2, and IL1A, p < 0.05) were decreased in the peripheral blood of CAD patients, the expression levels of three genes (CRH, PPP1R15A, and HRC, p < 0.05) were increased, and the expression levels of two genes did not change significantly (RNF183 and TMED2, p > 0.05) (Figure 6(b)).
