UCP2 and diabetes mellitus: No significant difference was observed when UCP2 gene expression was analyzed by gender (men: 0.84 ± 1.59 vs. women: 0.91 ± 1.21 n fold change; P = 0.879), AH status (normotensive: 0.59 ± 1.57 vs. hypertensive: 0.97 ± 1.31 n fold change; P = 0.442), or presence of DM (non-diabetic patients: 0.76 ± 1.44 vs. DM patients: 0.93 ± 1.30; P = 0.762 n fold change).
