The Role Of Human Endogenous Retroviruses In Renal Cell Carcinoma, Michele D. Tisdale
The Role Of Human Endogenous Retroviruses In Renal Cell Carcinoma, Michele D. Tisdale
Biological Sciences Theses & Dissertations
Human endogenous retroviruses make up approximately 8-9% of the human genome. A number of expressed HERVs, those that are actively transcribing, have been associated with various cancers. Suppression mechanisms that control HERV expression often fail or become more permissive in tissues where expression should be restricted. Previous studies have identified HERV expression in breast cancer tissues, whereas normal tissue HERV expression remained suppressed. In addition, studies of DNA hypermethylation have correlated with the ability to contribute to cancer development. Hypermethylation of several tumor suppressor genes occurs frequently in cancers and alterations in promoter regions could contribute to the development of …
Inhibition Of Yeast Hexokinase By The Antimalarial Drug Artemisinin: Probing Mechanism Of Action With A Model Enzyme, Jennifer S. Spence
Inhibition Of Yeast Hexokinase By The Antimalarial Drug Artemisinin: Probing Mechanism Of Action With A Model Enzyme, Jennifer S. Spence
Biological Sciences Theses & Dissertations
A leading infectious cause of death, malaria threatens approximately half of the world's population, and drug-resistant strains of Plasmodium falciparum have created immense difficulty in chemotherapy of the disease. The artemisinin (ART) class of antimalarials may represent a powerful solution. In addition to their safety, effectiveness, and moderate cost, they are the only drugs in use for which there has been no widespread evidence of clinical resistance. The exact parasiticidal mechanism of ART is highly contested, but evidence suggests that protein alkylation may play a role in cytotoxicity. in vitro essays were performed using yeast hexokinase (HK) to demonstrate a …
Immediate Effect Of Heel-Pain Orthosis And An Augmented Low-Dye Taping On Plantar Pressures And Pain In Subjects With Plantar Fasciitis, Tracy Andus
Human Movement Sciences & Special Education Theses & Dissertations
Research has been done investigating plantar pressures and pain in subjects with pathologies after the application of orthoses and arch taping. To date, however, no study has been conducted investigating plantar pressures and pain in subjects with plantar fasciitis after the application of the augmented low-dye taping (ALD) in comparison to a heel-pain orthosis (HPO). Therefore, the purpose of this study was to determine the effects of the ALD in comparison to a HPO on pain, peak plantar pressure (PPP), and mean plantar pressure (MPP) under multiple areas of the foot in subjects with plantar fasciitis while walking and jogging. …
Mechanisms Of Regulation Of Proximal Tubule Sodium Transporters In Obesity-Induced Hypertension, Marta A. Ambrozewicz
Mechanisms Of Regulation Of Proximal Tubule Sodium Transporters In Obesity-Induced Hypertension, Marta A. Ambrozewicz
Theses and Dissertations in Biomedical Sciences
Hypertension is one of the common complications of obesity. Using a rat model of diet induced obesity and hypertension we investigated some of the mechanisms that are involved in regulation of blood pressure in obesity. The first aim of this study was to determine the role of proximal tubule transporters on the renal sodium handling in obese hypertensive (OP) and lean normotensive (OR) rats. An acute increase in renal perfusion pressure resulted in a blunted natriuretic response in OP vs. OR rats and indicated that increased sodium reabsorption in the proximal tubule is casual, at least in part, for hypertension …
