The Atheroprotective Impact Of Anti-Mir-33a-5p/3p In Cultured Pro-Inflammatory Endothelial Cells, Kun Huang

All Dissertations

Atherosclerosis is the process of cholesterol buildup within arterial cells, which is considered a leading factor that causes certain cardiovascular diseases. Cholesterol accumulation within pro-inflammatory endothelial cells is thought to induce atherogenesis and accelerate atherosclerosis progression. Evidence suggests inhibiting the microRNA miR-33a in arterial cells may promote atheroprotection via increasing ABCA1 protein expression. MiR-33a is processed into two functional strands, miR-33a-5p and miR-33a-3p. The potential atheroprotective effect of inhibiting miR-33a-5p and/or miR-33a-3p precisely in pro-inflammatory endothelial cells is not fully understood, as data is scant regarding what potential atheroprotective impact ABCA1-dependent cholesterol within pro-inflammatory endothelial cells demonstrates, which occurs via …

Evaluation Of Pierce’S Disease-Resistant Grapevine Cultivars In Upstate South Carolina, Annie Bruno

All Theses

Interest in wine grape production is increasing in South Carolina, but Pierce’s Disease (PD) caused by the xylem-limited bacteria Xylella fastidiosa (Xf) is a major limiting factor. Xf is spread by sap-sucking insect vectors in the Cicadellidae family such as sharpshooters. In the United States, Xf has become endemic to the southeast as global temperatures rise, causing winter temperatures to increase, which allows the bacteria to survive year-round. However, PD-resistant grapevine hybrid cultivars have become available through breeding V. vinifera genes with native American Vitis species that are resistant to Xf. In this study, the PD-resistant grapevine …
