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 …
Sex-Dependent Effects Of Induced Acute Inflammation On Glucose Homeostasis And Rna Editing Enzymes, Christian A. Rivas
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 …
Tissue And Sex-Specific Rna Editing During Induced Acute Inflammation, Claire E. Nichols
Tissue And Sex-Specific Rna Editing During Induced Acute Inflammation, Claire E. Nichols
MSU Graduate Theses
A-to-I RNA editing is a process where select adenosine (A) nucleotides are deaminated by an editing enzyme, ADAR, to become inosines (I) in RNA transcripts. RNA editing can affect the sequence of the encoded protein and the regulation of the RNA. ADAR1 also plays a role in regulating innate immunity and its expression is upregulated during inflammation. Current data on the effects of increasing ADAR1 on RNA editing is limited, and most studies are completed only in male animals. We are interested in expanding RNA editing data to include female animals. Lipopolysaccharide (LPS) was used to induce acute inflammation and …
The Role Of Rna Editing Within Calcium-Dependent Activator For Secretion 1 In Large Dense Core Vesicle Fusion, Kaylee M. Mathiason
The Role Of Rna Editing Within Calcium-Dependent Activator For Secretion 1 In Large Dense Core Vesicle Fusion, Kaylee M. Mathiason
MSU Graduate Theses
Calcium-dependent activator protein for secretion 1 (CAPS1) is involved in synaptic vesicle and large dense core vesicle fusion by bridging vesicles and the plasma membrane prior to vesicle fusion and cargo release. CAPS1 is subject to a post-transcriptional modification called RNA editing. RNA editing recodes a single amino acid in the region of the protein that interacts with the vesicle. This recoding event within CAPS1 has cellular consequences in neurons where edited CAPS1 overexpression increases basal secretion from neural synaptic vesicles. Our goal was to investigate how RNA editing within CAPS1 affects large dense core vesicle secretion in an insulinoma …
