Tgfbeta1 And Stat3 As Regulators Of The Ha Synthesis And Signaling Pathway, Brenda Goretty Trevizo
Tgfbeta1 And Stat3 As Regulators Of The Ha Synthesis And Signaling Pathway, Brenda Goretty Trevizo
Legacy Theses & Dissertations (2009 - 2024)
The studies described here explored the role of Transforming Growth Factor Beta-1 (TGFβ1) and Signal Transducer and Activator of Transcription 3 (STAT3) as potential regulators of the Hyaluronic Acid (HA) synthesis and signaling pathway in human mammary cells. Our results support previous findings in which TGFβ1, a well characterized driver of the epithelial-mesenchymal transition (EMT) has been shown to regulate HA synthesis and signaling. Interrogation of The Cancer Genome Atlas (TCGA) indicated HAS2 expression positively correlated with TGFβ1 mRNA expression in breast cancer patients and in breast cancer cell lines. RT-qPCR experiments were used to measure the expression of the …
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.
Using A Novel Multiplexing Method To Track Cell Populations And Cytodifferentiation During Development Of The Submandibular Salivary Gland, Charles Thomas Manhardt
Using A Novel Multiplexing Method To Track Cell Populations And Cytodifferentiation During Development Of The Submandibular Salivary Gland, Charles Thomas Manhardt
Legacy Theses & Dissertations (2009 - 2024)
The development of submandibular salivary glands is complex and requires coordination of specific signaling events. Submandibular salivary glands originate as an epithelial invagination into the adjacent mesenchyme that leads to a single stalk and end bud; this end bud will go through a clefting process. Numerous rounds of clefting will lead to a fully developed salivary gland by this process, which is known as branching morphogenesis. As the gland undergoes morphogenesis, specific cues leading to differentiation of multiple cell types and even epithelial sub classes are required. By the later stages of development the glands are fully innervated, have an …
