Effects Of Niacin And Vitamin D On Endothelial Cell Angiogenic Function And Vascular Regeneration During Lipotoxicity, Kia Mae Peters

Electronic Thesis and Dissertation Repository

Observational studies have suggested an association between low levels of niacin and vitamin D and increased cardiovascular disease risk. Both vitamins have been shown to improve endothelial functions and vascular regeneration following vascular injury, however, it appears vitamin D may promote or inhibit neovascularization in a context-dependent manner. We hypothesized that supplementation of vitamin D alone and in combination with niacin, would improve endothelial cell function under lipotoxic conditions and promote revascularization and functional recovery in obese mice with ischemic injury. Matrigel assays, mRNA microarray analyses and growth rate assays were used to investigate angiogenic function of endothelial cells exposed …
