The Influence Of Mir-322 On Skeletal Muscle Differentiation, Miles Alexander Soyer
The Influence Of Mir-322 On Skeletal Muscle Differentiation, Miles Alexander Soyer
Legacy Theses & Dissertations (2009 - 2024)
Skeletal muscle plays a crucial role in coordinating voluntary movement and accounts for nearly 50% of total body mass. Dysregulation in skeletal muscle development is known to cause muscle degenerative diseases including the devastating Duchenne Muscular Dystrophy (DMD). The majority of the biological studies investigating muscle development were based on myogenic transcription factors and signaling molecules including: Pax7, Myf5, MyoD, WNT, TGF-β and BMP. After the discovery of non-coding RNAs including microRNAs, it was postulated that these molecules could regulate gene expression and thus affect differentiation and development. MicroRNAs are small non-coding RNAs (~17-25 nucleotides) that regulate gene expression negatively …

The salivary gland is an organ often taken for granted by most people. However, its proper function is essential for several everyday activities, such as speaking, swallowing, and tasting. As such, impaired salivary gland function, such as that caused by Sjögren’s Syndrome or radiotherapy for head and neck cancers, can lead to a significantly reduced quality of life. The cells that produce saliva in salivary glands are known as acinar cells, which arise from proacinar cells generated during embryonic development. As such, in studying the promoter regions of proacinar and acinar genes, it may be possible to identify common transcription …
Chromatin-Signaling Axis Orchestrates The Formation Of Germline Stem Cell Differentiation Niche In Drosophila, Maitreyi Upadhyay
Chromatin-Signaling Axis Orchestrates The Formation Of Germline Stem Cell Differentiation Niche In Drosophila, Maitreyi Upadhyay
Legacy Theses & Dissertations (2009 - 2024)
Stem cells have the unique capability of self-renewing into stem cells and differentiating into several terminal cell types. Loss of either of these processes can lead to aging, progression towards degenerative diseases and cancers. Insight into how self-renewal and differentiation are regulated will have tremendous therapeutic impact. Drosophila is an excellent model system for stem cell study due to the availability of various mutants, markers and RNAi technology. In order to study stem cell biology, we use female Drosophila gonads, whose stem cell population – the germline stem cells (GSCs) gives rise to gametes.
Investigation Into The Function Of Endothelial Cells And Their Signaling In Early Salivary Gland Development, Hae Ryong Kwon
Investigation Into The Function Of Endothelial Cells And Their Signaling In Early Salivary Gland Development, Hae Ryong Kwon
Legacy Theses & Dissertations (2009 - 2024)
Functional vasculature regulates organ formation and regeneration. Perfusion-independent and nutrition-independent endothelial regulation of epithelial patterning is of considerable interest for application in restoring parenchymal function. During murine submandibular salivary gland development, the vasculature co-develops with the epithelium; however, it is still unknown if the vasculature has instructive effects on the epithelium. A systems biological study revealed that endothelial genes are enriched in epithelial clefts, suggesting a potential involvement of endothelial cells in early morphogenesis. Using immunodepletion of the endothelial cells from the mesenchyme of reconstituted glands, a requirement for endothelial cells in epithelial patterning was demonstrated. Specifically, lobule formation was …
