Genetic Regulation Of Mucoidy In Pseudomonas Aeruginosa, T. Ryan Withers
Genetic Regulation Of Mucoidy In Pseudomonas Aeruginosa, T. Ryan Withers
Theses, Dissertations and Capstones
Cystic fibrosis is a genetic disorder that results from mutations in the CF transmembrane conductance regulator gene. These mutations cause a disruption in the chloride transport in mucosal tissues causing the accumulation of dehydrated mucus, and a decrease in the mucocilliary removal of environmental pathogens within the lungs. Additionally, the accumulation of dehydrated mucus within the lungs provides a hospitable environment for various bacteria, including the Gram-negative opportunistic pathogen Pseudomonas aeruginosa. P. aeruginosa uses the overproduction of a surface polysaccharide called alginate to form a biofilm to evade the host’s immunological defenses. The overproduction of alginate, often referred to as …

Shear Stress Induced Mtor Signaling In Cultured A7r5 Aortic Smooth Muscle Cell Line, Sriram Prasad Mupparaju
Theses, Dissertations and Capstones
Vascular intervention procedures such as balloon angioplasty and stent implantation lead to denudation of endothelium exposing the underlying smooth muscle layer to effects of blood shear stress. The effect of shear stress on smooth muscle cell signaling has not been studied in depth. In this study, we examined time dependent changes in activation of Akt, mTOR and p70S6k related signaling in response to orbital shear stress on cultured A7r5 cells. A7r5 cells cultured to subconfluence on 150mm culture dishes were subjected to orbital shear of 9.8dynes/cm 2 for zero, 5 min, 15 min, 30 min, 1h, 4h and 24h. The …
