Subset analysis of gene expression in individuals with (N = 26) and without (N = 66) diabetes and with (N = 24) and without (N = 66) hypertension showed significant differences for PTGS2 in individuals with diabetes (6.23±0.94 vs 2.93±0.40; p = 0.009) and hypertension (5.83±1.01 vs 3.04±0.39; p = 0.001), respectively. The gene discussed is PTGS2; the disease is diabetes mellitus.
