The Effects Of Oxidative Stress On P75ntr Signaling In Dopaminergic Neurons, Cassandra Marie Escobedo
The Effects Of Oxidative Stress On P75ntr Signaling In Dopaminergic Neurons, Cassandra Marie Escobedo
Online Theses and Dissertations
The p75 neurotrophin receptor (p75NTR) is responsible for implementing cellular death during embryonic development and in response to cellular injury. The receptor has been recognized as a contributor of neurodegeneration in numerous pathological conditions. Cleavage of p75NTR by Tumor Necrosis Factor converting enzyme (TACE) and γ-secretase has been observed to be associated with an increase in neurodegeneration. In a previous study, p75NTR was discovered to become activated in sympathetic neurons in response to oxidative stress induced by 4-hydroxynonenal (HNE) in a ligand-independent mechanism. Furthermore, cleavage of the receptor was demonstrated to contribute to the death of sympathetic neurons following oxidative …
Molecular Basis Of Sex Differences In Cardiac Hypertrophy And Heart Failure, Maya James
Molecular Basis Of Sex Differences In Cardiac Hypertrophy And Heart Failure, Maya James
Online Theses and Dissertations
Transforming growth factor beta ligands and receptors are known to be pro-hypertrophic and pro-fibrotic factors in the heart, and are known to contribute to the development of cardiac hypertrophy and heart failure. It is well established that premenopausal females possess a lower incidence of these pathologies. We and others have observed a greater level of fibrosis in male hearts compared to female hearts in rodent models of cardiac hypertrophy. It is well established that estrogen is cardioprotective in that it can prevent the development of cardiac hypertrophy, as well as abrogate the development of heart failure following sustained cardiac hypertrophy. …
Efficiency Of The Targetron Gene Knockout System As A Transformative Protocol For The Mutagenesis Of Listeria Monocytogenes, Hilaree Noele Frazier
Efficiency Of The Targetron Gene Knockout System As A Transformative Protocol For The Mutagenesis Of Listeria Monocytogenes, Hilaree Noele Frazier

The process of using electroporation to introduce plasmid DNA into host cells is a valuable molecular technique that is increasingly employed in labs worldwide. Electroporators are generally small and relatively inexpensive, making them attractive systems to use for a variety of purposes. Electroporation protocols are numerous in the published literature and encompass all cell types, from prokaryotic bacterial cells to eukaryotic human cells. The TargeTron Gene Knockout System by Sigma-Aldrich is an affordable option for the electroporation of numerous bacterial species. However, its use in Listeria monocytogenes has not been extensively characterized. Here we sought to discuss the effectiveness of …
Characterization Of Pregnancy Induced Cardiac Hypertrophy In Rats, Patricia Holden
Characterization Of Pregnancy Induced Cardiac Hypertrophy In Rats, Patricia Holden
Online Theses and Dissertations
During pregnancy, an increase in blood volume occurs to compensate for fetal development, resulting in cardiac hypertrophy. For the majority of women, this physiological cardiac hypertrophy resolves following pregnancy. Prolonged cardiac hypertrophy can lead to heart failure. We propose that by studying the biochemical mechanisms that mediate healthy cardiac remodeling associated with pregnancy, we will gain a better understanding of mechanisms involved in pathological cardiac hypertrophy. To determine the biochemical changes that occur during pregnancy induced cardiac remodeling, we subjected rats to timed matings and collected morphological and biochemical data from not pregnant, 19 days pregnant, and 24 hours postpartum. …
