Regulation Of Mpcs And Kat8 During Adipogenesis And Nutritional Regulation, Jasmine Burrell
Regulation Of Mpcs And Kat8 During Adipogenesis And Nutritional Regulation, Jasmine Burrell
LSU Doctoral Dissertations
Obesity is a global epidemic characterized by an expansion of adipose tissue. Adipose tissue, composed of adipocytes and a stromal vascular fraction, is an endocrine organ that regulates whole body homeostasis. Obesity leads to the dysregulation of adipocytes and is often associated with increased susceptibility to metabolic diseases such as Type II diabetes mellitus (T2DM). Understanding the mechanisms by which adipocyte function and development are regulated is crucial. Mitochondrial pyruvate carriers (MPCs) are transmembrane proteins that transport pyruvate from the cytosol into the mitochondrial matrix to generate acetyl CoA. Although MPCs have been studied extensively, their roles in adipocytes are …

Abstract: Background: Methylxanthines including caffeine and theobromine are widely consumed compounds and were recently shown to interact with bovine copper-containing amine oxidase. To the best of our knowledge, no direct demonstration of any interplay between these phytochemicals and human primary amine oxidase (PrAO) has been reported to date. We took advantage of the coexistence of PrAO and monoamine oxidase (MAO) activities in human subcutaneous adipose tissue (hScAT) to test the interaction between several methylxanthines and these enzymes, which are involved in many key pathophysiological processes. Methods: Benzylamine, methylamine, and tyramine were used as substrates for PrAO and MAO in homogenates …

Several therapeutic products based on mesenchymal stem cells (MSCs) have been translated into clinical applications. MSCs should undergo in vitro culture before a sufficient quantity can be achieved. Hence, both expansion kinetics and the biological characteristics of derived cells from primary culture are pertinent to their applications. In the present study, MSCs were isolated from rat bone marrow and adipose tissue (designated as bMSCs and aMSCs, respectively) and cells were comparatively analyzed regarding cell morphology, proliferation, colony formation, differentiation potential, and immunophenotype following the long-term subculture. No apparent differences could be noticed concerning the morphology between bMSCs and aMSCs. The …

Current procedures used for skin injury reepithelization have yet to improve. At present, stem cell-based therapies provide great potential in repairing different damaged tissues due to the multipotent character of these cells. This study aimed to investigate the in vitro differentiation capacity of human adipose-derived stem cells (ASCs) into epidermal cells and to evaluate their interaction with HaCaT keratinocytes in coculture experimental models that mimicked the living environment of human skin. The mesenchymal phenotype of isolated stem cells was indicated by their spindle-shaped morphology and the expression of specific surface markers CD73, CD90, and CD105. After 21 days of cultivation …

Mesenchymal stem cells (MSCs) can be found in many types of adult tissues such as the bone marrow, adipose, placenta, liver, and periosteum. Recently, adipose tissue-derived MSCs (ADMSCs) have become one the most preferred MSC types because of their fast proliferation rate, abundance, and high plasticity for variable cell types. It is known that ADMSCs are able to differentiate into various cells, including osteoblasts, so they are quite promising for orthopedic clinical trials. The present study aimed to compare the osteogenic differentiation conditions of MSCs from human adipose tissue (hADMSC) and those of MSCs from rat adipose tissue (rADMSC). Therefore, …

Sexual dimorphism in body weight, fat distribution, and metabolic disease has been attributed largely to differential effects of male and female gonadal hormones. Here, we report that the number of X chromosomes within cells also contributes to these sex differences. We employed a unique mouse model, known as the “four core genotypes,” to distinguish between effects of gonadal sex (testes or ovaries) and sex chromosomes (XX or XY). With this model, we produced gonadal male and female mice carrying XX or XY sex chromosome complements. Mice were gonadectomized to remove the acute effects of gonadal hormones and to uncover effects …

In this study, our aim was to develop a new simple technique for isolation of mesenchymal stem cells from adipose tissue. For this purpose, mesenchymal stem cells were isolated from rat adipose tissue by using the primary explant culture technique. When the cells became confluent, they were passaged 4 times by using the standard trypsinization method with trypsin/EDTA solution. Cells at second passage were characterized by using immunofluorescence staining against CD13 and CD29 markers. The results showed that these cultured cells were positive for CD13 and CD29 markers. Flow cytometry analysis was also done against CD29, CD90, CD54, MHC Class …
