Metabolic hormones (i.e., C-peptide, GLP-1, and insulin), inflammatory markers (i.e., TNF-α, IL-1β, and eotaxin) and adipokines (i.e., resistin, adipsin and lipocalin-2) levels were significantly (p < 0.05; fdr corrected p-value < 0.15) increased in T2DM_CAD group, while levels of GM-CSF (p < 0.001; fdr corrected p-value < 0.12) and PAI-1 were significantly (p < 0.05; fdr corrected p-value < 0.12) decreased in T2DM_CAD as compared to the control subjects. This evidence concerns the gene RETN and coronary artery disorder.
