Mhc Diversity Analysis Of Spheniscus Demersus For In Situ And Ex Situ Populations, Antonieta Van Den Berg Monsalve
Mhc Diversity Analysis Of Spheniscus Demersus For In Situ And Ex Situ Populations, Antonieta Van Den Berg Monsalve
Undergraduate Honors Thesis Projects
The South African Penguin has been listed as endangered by the International Union for Conservation of Nature. Major histocompatibility complex (MHC) alleles provide valuable statistics because of their variation in terms of vertebrate genomes and are pertinent to immune and reproductive health. A greater number of MHC alleles correlates with survivability of a population because the genes control the immune and reproductive systems. Legacy research by Otterbein alumni and Dr. Simon Lawrance studied MHC samples from wild, in situ, and captive, ex situ, penguin populations. By comparing these populations' major histocompatibility complexes through biostatistical analysis, contributions to conservation of the …
Probing The Function Of Perilipin 5b, Rebekah Dalton
Probing The Function Of Perilipin 5b, Rebekah Dalton
Undergraduate Honors Thesis Projects
Many modern health issues arise from aberrant lipid metabolism, among these are type II diabetes and non-alcoholic fatty liver disease. One commonality these diseases share is neutral lipid metabolism and storage. Regulation of neutral lipid metabolism is of vital importance in the body, and among the proteins responsible for such regulation are the perilipins. Perilipins are a family of five conserved proteins that are found on the surface of lipid storage droplets and play a central role in the regulation of cellular neutral lipid metabolism. Perilipin 5 specifically, is expressed in tissues with a high capacity for fatty acid oxidation …
Diversity Of The Major Histocompatibility Complex In African Penguins (Spheniscus Demersus) In Situ, Athena Schalk
Diversity Of The Major Histocompatibility Complex In African Penguins (Spheniscus Demersus) In Situ, Athena Schalk
Undergraduate Honors Thesis Projects
The Major Histocompatibility Complex (MHC) is responsible for the immune response in all jawed vertebrates and protects individuals against a variety of pathogens and diseases. Maintaining genetic diversity within the MHC exons is critical to protecting endangered species. African penguins (Spheniscus demersus) are in danger of losing their MHC diversity in isolated populations due to reductions in population size associated with environmental changes and human activity. This study analyzes the diversity within the exons in the DNA encoding the MHC by amplifying the exons through polymerase chain reaction and identifying alleles through denaturing gradient gel electrophoresis. Wild populations of …
Characterization Of The Perilipin 5 C-Terminus, Tim D. Clinton
Characterization Of The Perilipin 5 C-Terminus, Tim D. Clinton
Undergraduate Honors Thesis Projects
The crystallization of protein with subsequent X-Ray crystallography analysis is a powerful technique for uncovering a protein’s structure. This methodology is cutting edge and innovations are being made daily on how to best use the fundamentals of this technique for clearer characterizations. The protein Perilipin 5 could benefit from this technique as properties involving the structure of the molecule are still largely unknown. Knowing the structural aspects of perilipin 5 is important as several research efforts indicate that is a key factor in the regulation of lipolysis, or the breakdown of fats within a biological system. In the life sciences, …
Protein-Protein Interactions In Perilpin 5, Erin K. Hughes
Protein-Protein Interactions In Perilpin 5, Erin K. Hughes
Undergraduate Honors Thesis Projects
Many metabolic diseases contribute to a major part of the health crisis in the US. Type II diabetes mellitus and non-alcoholic fatty liver disease are two examples of metabolic diseases that are contributing to the current health crisis. Key to understanding these diseases and their progression is an understanding of neutral lipid metabolism. Perilipins are a class of five conserved proteins that are key regulators of lipid metabolism and are potentially involved in lipid trafficking within cells. The most recently discovered member of the family is perilipin 5, which is expressed most strongly in tissues that are highly oxidative such …
Insights Into The Cellular Trafficking Of Perilipin 5, Hannah M. Bailey
Insights Into The Cellular Trafficking Of Perilipin 5, Hannah M. Bailey
Undergraduate Honors Thesis Projects
Perilipins are a family of five proteins found on the surface of lipid storage droplets in nearly all tissues. These proteins act as cofactors for lipases and scaffolding for other proteins involved in lipid metabolism. In addition to the lipid droplet surface, members of the perilipin family have been found in the cytosol, endoplasmic reticulum, plasma membrane and mitochondria. The localization of these proteins is in part due to the phosphorylation state of the perilipin in question. Many other biological processes occur through kinase pathways, which have numerous cellular outcomes. Recently, perilipin 5 has been shown to localize to the …
Inquiry Into Perilipin-5a Expression In Triacylglycerol Rich Vs Normal Fed Mouse Tissue, Kobi Agyepong
Inquiry Into Perilipin-5a Expression In Triacylglycerol Rich Vs Normal Fed Mouse Tissue, Kobi Agyepong
Undergraduate Honors Thesis Projects
The steep rise in both childhood and adult obesity over the past three decades has moved to the forefront of public consciousness in recent years. This development has generated a marked increase in general health awareness and lifestyle changes for a vast number of individuals, most notably in the form of increased physical activity and diet alterations. The latter point is especially salient in a biochemical context, because of the myriad factors that can result in “fat accumulation”. Chief among these factors is the Perilipin 5A gene, (known as PLIN5A) which encodes the protein Perilipin 5A of the Perilipin family …
Iron Metabolism Genes In Browsing And Grazing Rhinoceroses: Implications For Iron Overload Disorder, Lorien Salyer
Iron Metabolism Genes In Browsing And Grazing Rhinoceroses: Implications For Iron Overload Disorder, Lorien Salyer
Undergraduate Honors Thesis Projects
Iron overload disorder is a serious condition that affects many animals of conservation interest, including rhinoceroses. Iron overload disorder is only found in browsing rhinos (African black, Diceros bicornis, and Sumatran, Dicerorhinus sumatrensis) but not in grazing species (African white, Ceratotherium simum, and greater one-horned, Rhinoceros unicornis). Iron overload is connected with many of the other health issues seen in captive browsing rhinoceroses, so it is vitally important that the iron metabolism process is studied to improve the existing husbandry procedures of these critically endangered animals. The objective of this study was to characterize genes related to …
Evidence Of A Perilipin 5 Splice Variant, Brodie Ranzau
Evidence Of A Perilipin 5 Splice Variant, Brodie Ranzau
Undergraduate Honors Thesis Projects
Alternative splicing occurs throughout the human genome, leading to multiple proteins from a single gene. The resulting proteins can be nearly identical or vastly different in how they function. Alternative splicing within the perilipin family has been observed in perilipins 1 and 3, giving rise to proteins with varying functions. In the course of our studies on perilipin 5, an immunoblot signal was observed that corresponded to an approximately 35 kDa protein. Western blot analysis of this protein has revealed its expression in C2C12 cultured myoblasts and in heart and liver mouse tissue. Further analysis of perilipin 5 cDNA through …
The Effect Of Red Maple Leaf Toxicosis On Reduced Glutathione Levels In Equine Erythrocytes In Vitro, Madeline A. Rohl
The Effect Of Red Maple Leaf Toxicosis On Reduced Glutathione Levels In Equine Erythrocytes In Vitro, Madeline A. Rohl
Undergraduate Honors Thesis Projects
Red maple leaf toxicosis is an equine blood disorder resulting from the consumption of wilted red maple (Acer rubrum L.) leaves by horses. Compounds within the leaves of red maple have oxidative effects on equine erythrocytes and can cause hemolysis of erythrocytes, the conversion of hemoglobin to methemoglobin, and the production of Heinz bodies. Reduced glutathione is important in the protection of equine erythrocytes from these oxidative events; however, in the presence of red maple toxin, glutathione is rapidly oxidized and is unavailable. The objective of this study is to determine whether the presence of vitamin C alters levels …
