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 …

Notch And Mediator Work Together To Direct Hasc Self-Renewal, Jaylen Mumphrey
Master's Theses
Stem cells are unique in that they possess totipotent, pluripotent, or multipotent differentiation capabilities and can also self-renew. Stem cells are in either a state of selfrenewal or differentiation, but never both. If we are able to gain a full understanding of the underlying mechanisms that allow stem cells to remain self-renewing and multipotent, we will better be able to control the fate of cells, ultimately allowing stem cells to be used to their full capabilities in regenerative medicine. My research focuses on MED12 and its effects on Notch signaling. Here we describe the expression profile and activity of MED12, …
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 …
