Phosphoproteomic Studies Of Smooth Muscle Contraction: Investigation Of Differential Phosphorylation In Relaxed/Contracted Rat Aortic Smooth Muscle Tissue Using Maldi-Tof Ms, Tonya M. Pekar
Theses, Dissertations and Capstones
Many human disorders are associated with the malfunction of smooth muscle tissue, or are related to the capabilities of its proper function—asthma, glaucoma, renal inefficiency, hypertension, and cardiovascular disease. Dysfunctional proteins are frequently implicated as the source of such disorders. As the second highest cause of death in the United States, the epidemic of cardiovascular disease makes the study of smooth muscle of utmost concern.
The capabilities of proteomics and mass spectrometry allow the entire proteome complement of a cell or tissue type to be analyzed at once. This investigation employs such techniques in an effort to better understand the …
A Mechanistic Study Of Myoglobin Nephrotoxicity, Jennifer L. Minigh
A Mechanistic Study Of Myoglobin Nephrotoxicity, Jennifer L. Minigh
Theses, Dissertations and Capstones
Myoglobin is an endogenous protein that can become nephrotoxic under certain conditions such as crush injuries, drug overdose, and seizures where prolonged contraction of muscle leads to cell death and leakage of myoglobin. The mechanism of myoglobin-induced nephrotoxicity is not fully understood. The purpose of this study was to characterize the sequence and mechanistic events associated with the in vitro toxicity of myoglobin in renal cortical slices. Renal tissue was isolated from Fischer 344 rats. Slices of renal cortex were prepared by freehand. These slices were then incubated for 60-180 minutes with myoglobin (0-12 mg/mL) pretreated with 4 mM ascorbic …

Methods Development For The Identification Of Unknown Proteins, Laura Brumfield Neal
Theses, Dissertations and Capstones
The chemistry of transport, storage, energy production, and reproduction in physiological systems is controlled by the actions and interactions of proteins. A species full complement of these amazing machines is often referred to as its proteome. The new science of proteomics utilizes a set of powerful and evolving tools to characterize the nature of the proteome, and further to fully elucidate the functional attributes of the proteins and their associations.
A methodology was developed by combining several proteomic techniques, such as electrophoresis, RP-HPLC, and mass spectrometry, to correctly identity proteins. Three known proteins (myoglobin, albumin, and actin) were employed for …
