Na/K-Atpase Alphα1 Regulates Adipogenesis Via Its Conserved Caveolin Binding Motif, Minqi Huang
Na/K-Atpase Alphα1 Regulates Adipogenesis Via Its Conserved Caveolin Binding Motif, Minqi Huang
Theses, Dissertations and Capstones
The Na/K-ATPase (NKA) was identified in 1957 by Dr. Jens C. Skou. It belongs to the P-type ATPase family, which can actively transport ions across cell membranes by using the energy from adenosine triphosphate (ATP) hydrolysis. During the second half of the 20th century, the molecular mechanism of the NKA catalytic cycle was clarified, and the isoform diversity of NKA in different species and organs was identified. The active ion transport through NKA generates cell membrane ion gradients and the electric potential. Hence, the enzymatic function of NKA is critical for cell viability as well as multiple physiological processes including …
Potential Counter Regulatory Effects Of A Gut Microbiota Metabolite In Alleviating Down-Regulation Krüppel-Like Factor 4 In Intestinal Inflammation, Ylva Forslund
Theses, Dissertations and Capstones
Inflammatory bowel disease (IBD) is a medical condition characterized by chronic inflammation of the intestinal epithelium. Krüppel-like factor 4 (KLF4), a zinc finger transcription factor, is vital for maintaining intestinal epithelial homeostasis. KLF4 promotes differentiation of goblet cells that generate the protective mucus layer. Reduced goblet cell number and defective mucus layer are associated with IBD. Shortchain fatty acids (SCFA) are known to play an important role in the maintenance of a strong and healthy intestinal epithelial layer and also in goblet cell differentiation. However, whether the positive effects of SCFAs on goblet cells are mediated, at least partly, via …
Targeting Epigenetic Mechanisms In Endometriosis, Sarah Elizabeth Brunty
Targeting Epigenetic Mechanisms In Endometriosis, Sarah Elizabeth Brunty
Theses, Dissertations and Capstones
Endometriosis is a complex and elusive gynecological disease in which the inner lining of the uterus grows in locations outside of the uterus and forms lesions. It is known to affect 1 in 9 women of reproductive age worldwide. Symptoms of endometriosis include severe pain, heavy periods, and infertility. While multiple theories of origin exist, none fully encompass all aspects of the disease, although all theories agree that this is an inflammation-driven disease. Due to this, many researchers are turning towards epigenetics to explain the initiation and progression of endometriosis. However, what is causing these epigenetic changes is still a …
Epigenetic Role Of Ptip In Mouse Spermatogenesis, Chengjing Liu
Epigenetic Role Of Ptip In Mouse Spermatogenesis, Chengjing Liu
Theses, Dissertations and Capstones
In mammals, spermatogenesis is a biological process inside the testis to produce spermatozoa from spermatogonia. This process is governed by both genetic and epigenetic mechanisms and thus is a powerful system for epigenetic research. Methylation of histone 3 lysine 4 (H3K4) is an epigenetic mark, which has been found to be dynamically modulated in mouse male germ cells during spermatogenesis. Pax2 Transactivation domain Interaction Protein (PTIP) has been recently identified as part of a H3K4 methyltransferase complex. In this study, I hypothesize that PTIP is an essential epigenetic regulator in mouse spermatogenesis. To test this hypothesis, I first established a …
Cerium Oxide Nanoparticles Attenuate Polymicrobial Sepsis Induced Splenic Damage In Male Sprague Dawley Rats, Venkata Vinay Kumar Bandarupalli
Cerium Oxide Nanoparticles Attenuate Polymicrobial Sepsis Induced Splenic Damage In Male Sprague Dawley Rats, Venkata Vinay Kumar Bandarupalli
Theses, Dissertations and Capstones
Sepsis is a serious life threatening medical emergency which, if not treated properly, oftentimes results in organ failure and death. Current sepsis treatment protocols are largely centered on the use of antibiotics and supportive care. Recent studies have suggested that antibiotics fail to be effective for sepsis treatment when administered during hypo-dynamic phase of sepsis that is usually characterized by the presence of a cytokine storm. As such, there is an urgent need to develop novel therapeutic drugs that target the inflammatory cytokines that are secreted as a result of increased reactive oxygen species. Cerium oxide nanoparticles (CeO2) have been …
Chmp1 Negatively Regulates Epidermal Growth Factor Signaling In The Drosophila Wing, Meagan Elisabeth Valentine
Chmp1 Negatively Regulates Epidermal Growth Factor Signaling In The Drosophila Wing, Meagan Elisabeth Valentine
Theses, Dissertations and Capstones
A critical step in cellular signaling through transmembrane receptors is the down-regulation of activated receptors through the multivesicular body (MVB) pathway to the lysosome. MVB generation is mediated by the highly conserved ESCRT (0, I, II, and III) protein complexes. Though the ESCRT-III complex provides the core function of the ESCRT machinery, it is the least characterized of the ESCRT complexes. The Chmp1 protein is an ESCRT-III component and a putative tumor suppressor that has been linked to pancreatic and renal cancers in humans. However, published data on Chmp1 activity are conflicting and its role during tissue development is not …
Characterization Of The Dna-Binding Properties Of Silent Information Regulator 3 Protein, Cotteka Nichisha Johnson
Characterization Of The Dna-Binding Properties Of Silent Information Regulator 3 Protein, Cotteka Nichisha Johnson
Theses, Dissertations and Capstones
The eukaryotic genome is organized into distinct domains with discrete regulatory potential, influenced by the variation in local chromatin structure. An example of chromatin-mediated consequences on gene expression is mating type determination of yeast Saccharomyces cerevisiae, which depends on silencing of specific gene cassettes. Silencing in yeast involves key proteins, amongst which the Silent Information Regulator (Sir) proteins are essential. Sir1p, Sir2p, and Sir4p are recruited to nucleate silencing events, while Sir3p serves as the pivotal factor in spreading the silent state. This investigation characterizes the DNA binding properties of Sir3p using DNA fragments with varying degrees of inherent flexibility, …
