Engineering And Characterizing Proteins: A Dual Study On Canine P53 Protein And Cyan Thermal Protein, Dhruv B. Sitapara
Engineering And Characterizing Proteins: A Dual Study On Canine P53 Protein And Cyan Thermal Protein, Dhruv B. Sitapara
MSU Graduate Theses
This research aims to explore protein development and characterization, focusing on a dual study of canine p53 protein and cyan thermal protein. For the canine p53 protein, the goal is to comprehend its structure to better understand a key component of canine cancers. This multi-step process involved expressing the canine p53 DNA-binding domain in E. coli and purifying it through affinity and ion-exchange chromatography. The purified protein was studied to test the binding of canine p53 protein to human DNA sequences using Surface Plasmon Resonance (SPR) experiments and an Electrophoretic Mobility Shift Assay (EMSA), visualized with a SYBR-safe stain. The …
Tissue And Sex-Dependent Regulation Of Innate Immunity And Rna Editing In Mice, Kelsey R. Kendrick
Tissue And Sex-Dependent Regulation Of Innate Immunity And Rna Editing In Mice, Kelsey R. Kendrick
MSU Graduate Theses
Inflammation occurs as a result of insult or infection within the body. Individual cells respond to inflammation by upregulating genes that help mediate the immune response, such as ADAR1. ADAR1 helps regulate the immune response but also catalyzes a process called RNA editing. RNA editing alters the sequence of select mRNAs to alter the encoded proteins. The result is altered function of the encoded protein, which is often beneficial for the cell. Our goal was to determine how inflammation affects the function of ADAR1. Since we know that the effects of inflammation vary between different organs and sexes, we examined …

Impact Of Sample Conditions On Dna Phosphodiester Backbone Bi/Bii Conformational Equilibrium Dynamics, Autumn C. Pilarski
MSU Graduate Theses
DNA damage, such as single base lesions and mismatches, is highly prevalent within cells. If these DNA damage events are not repaired, they could lead to mutations and thus disease and cancer. Intricate repair mechanisms are in place to fix these damage events, one such being Base Excision Repair (BER) and associated enzyme: Thymine DNA Glycosylase (TDG). The first step of this repair process, recognition of the lesion by TDG, is not well understood. The following thesis presents results to better understand the fundamental biophysical question of how a DNA lesion within a mismatch context is recognized in a million …

Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas
MSU Graduate Theses
The first line of defense against bodily insults, like pathogen invasion, is the innate immune system. Innate immunity sets in motion countless cascades that result in inflammation. Inflammation simultaneously affects multiple biological processes like metabolism and gene expression. Males and females react differently to inflammation. To understand both molecular and physiological sex differences in inflammation, we examined how inflammation affects gene expression and glucose metabolism. Adenosine deaminase acting on RNA (ADAR1) is upregulated by inflammation and catalyzes RNA editing, a process where nucleotides encoded by the genome are modified. ADAR1 also controls the innate immune reaction by decreasing activity of …
