Tgfbeta1 And Stat3 As Regulators Of The Ha Synthesis And Signaling Pathway, Brenda Goretty Trevizo Aug 2020

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 …


Launching The Next Generation : Transcriptional Regulation During Oogenesis, Alicia K. Mccarthy Jan 2020

Launching The Next Generation : Transcriptional Regulation During Oogenesis, Alicia K. Mccarthy

Legacy Theses & Dissertations (2009 - 2024)

Germ cells give rise to gametes and link generations by passing genetic information from parent to offspring. Gametes arise from, in many sexually reproducing organisms, germline stem cells (GSCs) which are set aside early during development. GSCs have an amazing capacity to undergo self-renewal to give rise to a pool of undifferentiated cells, while also differentiating to generate specialized germ cells such as haploid gametes. Upon female GSC differentiation, mitotically dividing germ cells can initiate meiosis, and mature within a follicle. During maturation, the specified oocyte is provided with a trust fund of RNAs and proteins for the next generation …


Regulation Of Gene Expression Through Ribosome-Associated Proteins, Clare Margaret Miller Jan 2020

Regulation Of Gene Expression Through Ribosome-Associated Proteins, Clare Margaret Miller

Legacy Theses & Dissertations (2009 - 2024)

Translation is a crucial mechanism for generating proteins to carry out cellular processes and for ensuring proper cell functions. Ribosomes are at the center of translation and are complex pieces of machinery. They consist of at least 80 core eukaryotic ribosomal proteins, which are conserved from prokaryotes, and four ribosomal RNAs (rRNAs): 18S, 28S, 5,8A 5S. In addition, numerous translation factors aid the ribosome in protein production. While ribosomes are typically described by these core features, they are known to exist in a heterogenous pool with variations in protein composition, modifications of rRNA, and an assortment of non-ribosomal proteins that …

Adaptation Of Vibrio Cholerae O1 To Protective, Lipopolysaccharide-Specific Antibodies In The Intestinal Lumen, Danielle Elizabeth Baranova Jan 2020

Adaptation Of Vibrio Cholerae O1 To Protective, Lipopolysaccharide-Specific Antibodies In The Intestinal Lumen, Danielle Elizabeth Baranova

Legacy Theses & Dissertations (2009 - 2024)

The outer membrane (OM) of Gram-negative enteric pathogens like Vibrio cholerae is a barrier against host defense factors, as well as a sensor of physical and chemical stimuli that the bacteria encounter in the gastrointestinal tract. The OM is also the primary target of the mucosal immune response, which consists of secretory antibodies primarily directed against lipopolysaccharide (LPS). ZAC-3 is a monoclonal antibody (MAb) that targets the conserved core/lipid A region of LPS of the pandemic V. cholerae O1 serotype. In a neonatal mouse model, passively administered ZAC-3 IgG has been shown to reduce the ability of V. cholerae to …


The Guardian Of The Genome : Regulation Of The Enhancer Networks Governing The P53-Mediated Stress Response, Allison Catizone Jan 2020

The Guardian Of The Genome : Regulation Of The Enhancer Networks Governing The P53-Mediated Stress Response, Allison Catizone

Legacy Theses & Dissertations (2009 - 2024)

After fertilization in vertebrates, cells work to build organs, tissues and begin to rapidly differentiate and proliferate. This process is the orchestration of finely tuned signals and perfectly timed gene expression patterns. The first step in gene expression, transcription, is governed by proteins known as transcription factors (TF). TFs are responsible for binding to DNA, altering chromatin structure, and driving activation of other genes based on the organism’s needs. Once the process of development is complete, organisms shift their resources to maintaining homeostasis. Humans regularly encounter outside stressors such as UV radiation, pollution, allergens, and drugs. Cells also accumulate mutations …
