Antiadipogenic And Antiobesogenic Effects Of Pterostilbene In 3t3-L1 Preadipocyte Models, Bi̇rgül Gülnar, İpek Canatar, Si̇bel Özdaş
Antiadipogenic And Antiobesogenic Effects Of Pterostilbene In 3t3-L1 Preadipocyte Models, Bi̇rgül Gülnar, İpek Canatar, Si̇bel Özdaş
Turkish Journal of Biology
Since obesity causes at least 2.8 million death each year and is a major risk factor for many diseases, it is critical to evaluate alternative treatment approaches. In this context, studies on the research of natural product-based therapeutics in the fight against obesity are increasing. In this study, it was aimed to evaluate the antiadipogenic and antiobesogenic efficacy of pterostilbene a natural phenolic compound in 3T3-L1 cells. The mature 3T3-L1 adipocytes were exposed to pterostilbene at different concentrations and half-maximum inhibitory concentrations (IC50) were determined by MTT assay. Oil-Red-O staining was applied to determine lipid accumulation. Phase contrast microscopy, Giemsa, …
The Role Of Med31 And Med12 In Directing Adipogenesis Of Human Adult-Derived Mesenchymal Stem Cells, Joseph Straub
The Role Of Med31 And Med12 In Directing Adipogenesis Of Human Adult-Derived Mesenchymal Stem Cells, Joseph Straub
Master's Theses
Selective gene expression is crucial in maintaining the self-renewing and multipotent properties of stem cells. Mediator is a large, evolutionarily conserved, multisubunit protein complex that modulates gene expression by relaying signals from cell type-specific transcription factors to RNA polymerase II. In humans, this complex consists of 30 subunits arranged in four modules: head, middle, tail, and kinase. In our introduction, we show the state of the field of Mediator study with a focus on the critical kinase module. In the following chapters, we used siRNA knockdowns to investigate the roles of the highly-conserved core subunit MED31 and the kinase module …

The Role Of Med12 In Adipogenesis, Caroline Helen Rinderle
The Role Of Med12 In Adipogenesis, Caroline Helen Rinderle
Master's Theses
In order for any function to occur within a cell, transcription factors must be able to interact with genes. When this occurs, genes are expressed, and ultimately, proteins are translated and perform the specific function that needs to be done within the cell. In order for this to occur, genes must interact with transcription machinery. The Mediator complex recruits transcription factors to genes in order to promote cell-type specific gene expression. The Mediator complex is a multi-protein complex consisting of four modules: head, middle, tail, and kinase. The kinase module is known to dissociate from the rest of the complex …
The Role Of Med12 In Adipogenesis Of Human Adipose Stem Cells, Onyekachi Chinelo Idigo
The Role Of Med12 In Adipogenesis Of Human Adipose Stem Cells, Onyekachi Chinelo Idigo
Master's Theses
The interest in adipogenesis stems from the high rate of obesity in the world and the motivation to better understand the process of cell fate in relation to human diseases. Mutations in MED12 lead to developmental disorders and certain malignancies. To date, specific roles of Mediator and MED12 in cell state regulation are unclear, nevertheless, they are critical for understanding stem cell regulation and enhancement of their clinical applications. This study investigates the role of MED12 in relation to the Mediator complex kinase domain to better understand transcriptional control of adipogenesis in hASCs. In this study, MED12 expression was diminished …

Brown adipose tissue (BAT) represents a promising agent to ameliorate obesity and other metabolic disorders. How- ever, the abundance of BAT decreases with age and BAT paucity is a common feature of obese subjects. As brown adipocytes and myoblasts share a common Myf5 lineage origin, elucidating the molecular mechanisms underlying the fate choices of brown adipocytes versus myoblasts may lead to novel approaches to expand BAT mass. Here we identify MyoD as a key negative regulator of brown adipocyte development. CRISPR/CAS9-mediated deletion of MyoD in C2C12 myoblasts facilitates their adipogenic transdifferentiation. MyoD knockout downregulates miR- 133 and upregulates the miR-133 …

FIU Electronic Theses and Dissertations
For the first time in human history, more people worldwide suffer from obesity than are undernourished. Numerous health complications are associated with obesity including cardiovascular disease, Type 2 Diabetes, cancers of reproductive tissues, stroke, depression, anxiety disorders, and Alzheimer’s disease. A deeper understanding of the anti-adipogenic effects and mechanism of action of sesquiterpene lactones may have pharmacological import in the continuing search for therapeutic modalities to ameliorate the effects of this global obesity epidemic.
Dehydroleucodine (DhL), 11,13-dihydro-dehydroleucodine (DH-DhL), and dehydroparashin-B (DhP), sesquiterpene lactones extracted from or derived from compounds extracted from Artemisia douglasiana, were investigated for their anti-adipogenic effects …

Stem cell-based applications have become a popular and promising approach for therapy for a number of disorders including neurodegenerative diseases, degenerative muscle diseases, and osteoporosis, as well as trauma, inflammations, burns, and injuries. Human tooth germ stem cells are an adult stem cell source; they have mesenchymal stem cell properties and show high proliferative and differentiation capacity. Melatonin has been demonstrated to regulate differentiation of human and mouse mesenchymal stem cells into various cell lineages in addition to its other functions in the body. In the current study, the effects of melatonin on osteogenic, neurogenic, adipogenic, chondrogenic, myogenic, and odontogenic …

Influence Of Lactobacillus Rhamnosus Isolated From “Amabere Amaruranu” Cultured Milk On Adipogenesis, Justin E. Kotala
Electronic Theses and Dissertations
This study was performed to test the in vitro effects of a Lactobacillus rhamnosus isolate from “amabere amaruranu”, a traditional Kenyan cultured milk, on 3T3-L1 and Caco-2 cell lines. Cultures of fully mature 3T3-L1 adipocytes were treated with bacterial isolate cell extract (CE), filtered spent broth (FSB) from overnight bacterial culture, or with a PBS control. Expression levels of PPAR³1 and 2, C/EBP±, and ATGL proteins in 3T3-L1 cells were upregulated by FSB treatment. CE treatment did not affect protein expression levels. Expression of MTTP and SREBP-1c proteins in Caco-2 cells showed no change with either treatment. Optical density measurements …

Novel Insights Into The Mechanisms Of Regulation Of Tyrosine Kinase Receptors By Ras Interference 1, Adriana Galvis
FIU Electronic Theses and Dissertations
Receptor-tyrosine kinases (RTKs) are membrane bound receptors characterized by their intrinsic kinase activity. RTK activities play an essential role in several human diseases, including cancer, diabetes and neurodegenerative diseases. RTK activities have been regulated by the expression or silencing of several genes as well as by the utilization of small molecules.
Ras Interference 1 (Rin1) is a multifunctional protein that becomes associated with activated RTKs upon ligand stimulation. Rin1 plays a key role in receptor internalization and in signal transduction via activation of Rab5 and association with active form of Ras. This study has two main objectives: (1) It determines …
