Abstract
Niacin was shown to inhibit acute vascular inflammation and improves endothelial dysfunction independent of changes in plasma lipids. Here, we investigated whether niacin can increase blood flow recovery after tissue ischemia by enhancing endothelial progenitor cell (EPC) functions in diabetic mice. Starting at 4 weeks after the onset of diabetes, vehicle or niacin (40 mg/kg/day) was administered daily by gavage to streptozotocin (STZ)-induced diabetic mice and diabetic endothelial nitric oxide synthase (eNOS)-deficient mice. Unilateral hindlimb ischemia surgery was conducted after 2 weeks of vehicle or niacin treatment. Compared to the control group, the niacin group had significantly increased ischemic/non-ischemic limb blood perfusion ratio and higher capillary density. These effects were markedly reduced in STZ-induced diabetic eNOS-deficient mice. Flow cytometry analysis showed impaired EPC-like cell (Sca-1+/Flk-1+) mobilization after ischemia surgery in diabetic mice but augmented mobilization in the mice treated with niacin. Diabetes was induced by administering STZ to FVB mice that received eGFP mouse bone marrow cells to evaluate effects of niacin on bone marrow-derived EPC homing and differentiation to endothelial cells. Differentiation of bone marrow-derived EPCs to endothelial cells in the ischemic tissue around vessels in diabetic mice that received niacin treatment, was significantly increased than that in control group. By in vitro studies, incubation with niacin in high-glucose medium reduced H2O2 production, cell apoptosis, and improved high glucose-suppressed EPC functions by nitric oxide-related mechanisms. Our findings demonstrate that niacin increases blood flow recovery after tissue ischemia in diabetic mice through enhancing EPC mobilization and functions via nitric oxide-related pathways.
