The levels of MIF, insulin, ghrelin, leptin, glucagon, resistin and adipsin are similar in type 2 diabetes and CHD patients whereas IL-1α, IL-2R, IL-12, IL-18, HGF, and PAI-1 are higher in CHD patients than in type 2 diabetes patients (with p-value <0.01). This evidence concerns the gene RETN and type 2 diabetes mellitus.
