Essential Amino Acid (Eaa) Regulation Of Skeletal Muscle Protein Turnover With Age, Mary Komp May 2022

Essential Amino Acid (Eaa) Regulation Of Skeletal Muscle Protein Turnover With Age, Mary Komp

Graduate Theses and Dissertations

Skeletal muscle (SM) is vital for both long term health and quality of life. Recent research suggests an increase in catabolic signals with age triggers pathologic conditions, such as sarcopenia. Although results from in vitro studies model how EAA can regulate muscle protein synthesis (MPS), the relevance of these models to muscle protein breakdown (MPB) and the presence of physiological EAA concentrations remains to be established. Therefore, the objective of this study was to determine the effects of a low, normal, and supra physiological dose of EAA (0.2, 1.0, and 3.0 x EAA) in a young (passages 2-10) and aging …


The Effect Of Epa And Dha On Skeletal Muscle Physiology And Energy Balance, Saeed Jebor Ghnaimawi Dec 2020

The Effect Of Epa And Dha On Skeletal Muscle Physiology And Energy Balance, Saeed Jebor Ghnaimawi

Graduate Theses and Dissertations

Eicosapentaenoic acid (EPA) and Docosahexaenoic acid (DHA) supplementation commonly suggested during pregnancy confers many health benefits on offspring and more recently improves fetal BAT development and induces myoblast trans-differentiation into adiopocytes through activating PPARs expression. Embryonic myoblast is a highly flexible cell showing great capacity to change its phenotype into adipocyte in response to EPA and DHA supplementation in many in vitro models. However, a little is known about the identity of derived adipocytes, whether, they change into brown or white adipocyte, and in vivo evidence is still missing. Given that the myogeneis process is initiated at the mid of …


Nutritional Supplementation And Skeletal Muscle Health In Chronic Diseases, Hexirui Wu May 2020

Nutritional Supplementation And Skeletal Muscle Health In Chronic Diseases, Hexirui Wu

Graduate Theses and Dissertations

Prevalence of chronic diseases in the United States keeps increasing in recent years. There are approximately four in ten adults having chronic diseases in America. Chronic diseases include obesity, aging, heart diseases, cancer and many others. This thesis mainly focuses on obesity and aging. Skeletal muscle performance is impaired in obesity and aging conditions. One common reason causing this could be higher fat mass and lower muscle mass. However, there is no study showing what pathways are involved in the imbalance of body composition. Therefore, the first objective of the thesis is to determine gene expression of selected pathways in …


Liver Transcriptomic Analysis After Short- And Long-Term Feeding Of Soy Protein Isolate And Its Ability To Reduce Liver Steatosis In Obese Zucker Rats, Melisa Kozaczek May 2020

Liver Transcriptomic Analysis After Short- And Long-Term Feeding Of Soy Protein Isolate And Its Ability To Reduce Liver Steatosis In Obese Zucker Rats, Melisa Kozaczek

Graduate Theses and Dissertations

According to the Centers for Disease Control and Prevention (CDC) the prevalence of obesity in adults in the United States during 2017-2018 was a 42.4%, a high number considering all the risks factors associated with this disorder, such as cardiovascular disease, insulin resistance, diabetes type 2, and fatty liver disease, among others. Fatty liver disease is the accumulation of lipids in the liver that can account for more than 5 to 10% of the liver’s weight. There are two types of fatty liver disease, alcoholic fatty liver disease (AFLD), and non-alcoholic fatty liver disease (NAFLD). AFLD is the detrimental accumulation …
