Figure 6A shows that the mRNA expression level of HSP90AA1 was lower (P < 0.05) and that the mRNA expression level of CEBPA (P < 0.01) was higher in the CAD group than in the control group. These results are consistent with the GSE12288 and GSE71226 datasets. There was no significant difference in FOXO1 expression between the two groups (P = 0.54). Here, HSP90AA1 is linked to coronary artery disorder.
