Regulation Of Cancer Metastasis By Protein Kinase D1: A Global Regulatory Cascade, Aditya Ganju
Regulation Of Cancer Metastasis By Protein Kinase D1: A Global Regulatory Cascade, Aditya Ganju
Theses and Dissertations (ETD)
Protein Kinase D1 (PKD1) is a serine threonine kinase which is downregulated in Prostate, Breast and Colon Cancer. It functions as a tumor suppressor in different cancer cells. Downregulation of PKD1 is known to be associated with aggressiveness of the cancer. PKD1 is known to regulate many key oncogenic signaling pathways such as E-cadherin, β-catenin and Androgen Receptor signaling pathways. Aberrant expression of these oncogenic pathways leads to transformation of cells from normal to malignant phenotype, thereby leading to increased proliferation, growth and metastasis to distant organs of these cancer cells. Literature evidence also points to the fact that E-cadherin …
Antibiotic Drug Discovery With An Eye Towards Overcoming Drug Resistance, Daniel Towner Hoagland
Antibiotic Drug Discovery With An Eye Towards Overcoming Drug Resistance, Daniel Towner Hoagland
Theses and Dissertations (ETD)
As a species, humans have become ever reliant on the use of antibiotics to facilitate our everyday lives. The widespread emergence of resistance to currently used antibiotics is commonly attributed to an over use in our society. Such resistance, coupled with a lack of innovation and production of novel antibiotic drugs, threatens to return humanity to an era similar to one before the discovery of the first antibiotics. The need to find new agents to be used in this fight is paramount, as well as learning from our recent failures to produce such compounds. This document will highlight my efforts …
Discoveries Of Targets And Novel Agents For The Treatment Of Ischemic Retinopathy And Neovascular Disease, Jordan Javad Toutounchian
Discoveries Of Targets And Novel Agents For The Treatment Of Ischemic Retinopathy And Neovascular Disease, Jordan Javad Toutounchian
Theses and Dissertations (ETD)
Diabetic retinopathy (DR) and age-related macular degeneration (AMD) are among the most common causes of blindness in adults. Vision loss can occur during the advanced stages of DR and AMD as a consequence of unregulated and dysfunctional growth of new blood vessels, or neovascularization (NV) in the retina or choroid. NV can also be triggered by numerous other ocular insults and diseases including radiation retinopathy (RR) and retinal vein occlusion. These latter cases are generally less common but, like DR and AMD, they are characterized by an initial injury, chronic inflammation, and ischemia which perpetuates episodes of retinal neovascularization (RNV). …
Repeated Zolpidem Treatment Effects On Sedative Tolerance, Withdrawal, Mrna Levels, And Protein Expression, Brittany T. Wright
Repeated Zolpidem Treatment Effects On Sedative Tolerance, Withdrawal, Mrna Levels, And Protein Expression, Brittany T. Wright
Theses and Dissertations (ETD)
Zolpidem and benzodiazepines (BZs) potentiate the inhibitory action of gamma-Aminobutyric acid (GABA) by allosterically binding to GABAA receptors (GABAAR). Prolonged use of GABAAR positive allosteric modulators (PAM) can lead to behavioral tolerance, the diminished response to the same drug dose with repeated use, and withdrawal, a group of symptoms that occur due to abrupt end of drug treatment. Zolpidem is a short-acting, non-BZ GABAAR PAM whose potential for tolerance and withdrawal is unclear. Zolpidem demonstrates sedative efficacy similar to BZs and has become a main treatment of insomnia in lieu of BZs. Zolpidem replaced BZs due to lower incidences of …
Hit Identification For Pkcζ Inhibitors: Structure-Based Optimization, Virtual Screening, And Biological Evaluation, Xiaoxin Wu
Theses and Dissertations (ETD)
Protein kinase C ζ (PKCζ) is believed to be a promising target for the treatment of some diseases, including inflammatory diseases, obesity and diabetes. Hit identification of PKCζ inhibitors was conducted by structure-based modification, virtual screening and biological evaluation. Among all the compounds selected and synthesized, compound JW-1-60A showed moderate activity against PKCζ at 30 μM and 100 μM. The molecular modeling studies showed that the binding mode of JW-1-61A was very close to the binding mode of JP-3-149, a reported PKCζ inhibitor with very potent activity, which might partially explain the moderate activity of JW-1-61A. Based on the structure …
