A Systems Chemical Biology Approach For Dissecting Differential Molecular Mechanisms Of Action Of Clinical Kinase Inhibitors In Lung Cancer, Natalia Junqueira Sumi
A Systems Chemical Biology Approach For Dissecting Differential Molecular Mechanisms Of Action Of Clinical Kinase Inhibitors In Lung Cancer, Natalia Junqueira Sumi
USF Tampa Graduate Theses and Dissertations
Lung cancer is the second most common cancer type and is associated with high mortality rates. The survival rate for lung cancer patients has increased slowly in the last decade mainly as the result of the development of novel targeted and immune therapies. However, non-small cell lung cancer patients lacking known or actionable driver mutations and small cell lung cancer patients with recurrent disease are still in urgent need of new therapies. Drug repurposing is an efficient way to identify new therapies since it uses clinically relevant small molecule drugs. Determination of off-targets of small molecules is a novel approach …
Determination Of Adamts13 Susceptibility In Type Iia Von Willebrand Disease, Monica Buselli
Determination Of Adamts13 Susceptibility In Type Iia Von Willebrand Disease, Monica Buselli
Dissertations, Masters Theses, Capstones, and Culminating Projects
von Willebrand Disease (vWD) is a bleeding disorder caused by a deficiency in von Willebrand Factor (vWF), a large glycoprotein that assists in coagulation. Specifically, large vWF multimers in the blood stream are key components in starting the coagulation cascade. vWF is cleaved by the metalloprotease ADAMTS13, regulating the multimers size, which hinders vWF’s ability to function properly. The three main types of vWD —Type I, II, and III— are not well defined, and as a result are all similarly treated with plasma-derived vWF replacement therapy. Plasma-derived vWF is a treatment that does not cure the problem but relieves the …
The Role Of Phosphohistidine Phosphatase 1 In Ethanol-Induced Liver Injury, Daniel Richard Martin
The Role Of Phosphohistidine Phosphatase 1 In Ethanol-Induced Liver Injury, Daniel Richard Martin
USF Tampa Graduate Theses and Dissertations
Chronic liver diseases, which includes alcoholic liver disease (ALD), are consistently among the top 15 leading causes of death in the United States. ALD is characterized by progression from a normal liver to fatty liver disease (hepatic steatosis), which can lead to cirrhosis, alcoholic hepatitis, and liver failure. We have identified a novel role of phosphohistidine signaling, mediated through phosphohistidine phosphatase 1 (PHPT1), in the onset of hepatic steatosis. We have identified PHPT1 as a target of selective oxidation following acute ethanol exposure as well as being downregulated following chronic ethanol exposure. We mapped the oxidative modification site and developed …
Proteogenomic Study Of Nitrogen-Fixing Cyanobacterium Anabaena Cylindrica, Yeyan Qiu
Proteogenomic Study Of Nitrogen-Fixing Cyanobacterium Anabaena Cylindrica, Yeyan Qiu
Electronic Theses and Dissertations
Cyanobacteria are gram-negative photosynthetic bacteria. In some filamentous cyanobacteria such as Anabaena cylindrica, every 10th to 20th vegetative cells can differentiate into nitrogen fixing heterocysts. Heterocyst can induce the neighboring cells developing into spore-like akinetes. The specialized cell functions and resourceful networks have contributed to the prosperity of cyanobacteria for over 2 billion years, but the genetic mechanisms for multi-cellular differentiation are barely known, especially for akinete formation. The heterocysts, akinetes and vegetative cells of Anabaena cylindrica were isolated for proteomic study. This study identified a total of 1395 proteins, including 664 proteins from akinetes, 751 proteins from …
Influence Of Dietary Ractopamine And Supranutritional Supplementation Of Vitamin E On Proteome Profile Of Postmortem Beef Longissimus Lumborum Muscle, Hyun Mok Kim
Theses and Dissertations--Animal and Food Sciences
The effects of dietary ingredients on the proteome profile of postmortem beef longissimus lumborum (LL) muscle were evaluated. In the first experiment, the influence of dietary ractopamine on the whole-muscle proteome of beef LL was examined. Five proteins were differentially abundant between ractopamine-fed (RAC) and non-ractopamine fed (CON) groups. The differentially abundant proteins were over-abundant in RAC and were related to muscle structure development (F-actin-capping protein subunit beta-2 and PDZ and LIM domain protein-3), chaperone (heat shock protein beta-1), oxygen transportation (myoglobin), and glycolysis (L-lactate dehydrogenase A chain). These findings indicated that ractopamine influences the abundance of proteins associated with …
