The Role Of Yes-Associated Protein 1 In Ovarian Physiology And Pathology, Xiangmin Lv
The Role Of Yes-Associated Protein 1 In Ovarian Physiology And Pathology, Xiangmin Lv
Theses & Dissertations
Ovarian granulosa cells are the major somatic components of the ovarian follicle. Proper proliferation and differentiation of ovarian granulosa cells are essential for successful follicle development. Accumulating evidence indicates that the Hippo-YAP signaling pathway plays critical roles in both development and tumorigenesis of several organs. The present study aims to investigate the role of Yes-associated protein 1 (YAP) in ovarian granulosa cell proliferation, differentiation, and malignant transformation. At first, we found that nuclear YAP (active) was highly expressed in proliferative granulosa cells, whereas cytoplasmic YAP (inactive) was detected mainly in terminally-differentiated luteal cells. Further studies suggested that endogenous YAP activity …
Novel Therapeutic Strategies For Treatment Of Castration-Resistant Prostate Cancer, Matthew A. Ingersoll
Novel Therapeutic Strategies For Treatment Of Castration-Resistant Prostate Cancer, Matthew A. Ingersoll
Theses & Dissertations
Prostate cancer (PCa) remains the most commonly diagnosed solid tumor and is the third leading cause of cancer-related death in United States men. While androgen deprivation therapy is the current standard-of-care treatment for metastatic PCa, most patients eventually relapse and develop castration-resistant (CR) tumors, for which there is currently no effective treatment. Therefore, synthesis of novel therapeutic agents and identification of alternative target proteins are necessary to improve treatment. Herein, I investigate the efficacy of novel imidazopyridine and statin derivatives as alternative therapeutic compounds. These molecules not only inhibit androgen receptor signaling, but also block activation of the AKT axis, …
Understanding The Chondrogenic Potential Of Articular Chondrocytes, Krishna Sarma
Understanding The Chondrogenic Potential Of Articular Chondrocytes, Krishna Sarma
Theses & Dissertations
Articular cartilage is a smooth, visco-elastic, aneural, avascular tissue made of water, an exquisitely organized framework of proteoglycans, glycosaminoglycans, and collagen fibrils and articular chondrocytes. It’s beautiful organization and composition provide it with the flexibility and strength to cover, protect and lubricate the ends of long bones in a diarthrodial joint. Cartilage homeostasis relies on articular chondrocytes to translate the mechanical forces of daily activity into efficient remodeling of the extracellular matrix. Age, joint injury, or other insulting factors can progressively incapacitate articular chondrocytes, resulting in cartilage lesions that devolve to degenerative joint disease. Therefore, the central idea explored in …
Foxo3 Increases Mir-34a To Cause Palmitate-Induced Cholangiocyte Lipoapoptosis., Sathish Kumar Natarajan, Bailey A. Stringham, Ashley M. Mohr, Cody J. Wehrkamp, Sizhao Lu, Mary A. Smith, Dee Harrison-Findik, Justin L. Mott

Nonalcoholic steatohepatitis (NASH) patients have elevated plasma saturated free fatty acid levels. These toxic fatty acids can induce liver cell death and our recent results demonstrated that the biliary epithelium may be susceptible to lipotoxicity. Here, we explored the molecular mechanisms of cholangiocyte lipoapoptosis in cell culture and in an animal model of NASH. Treatment of cholangiocytes with palmitate (PA) showed increased caspase 3/7 activity and increased levels of cleaved poly (ADP-ribose) polymerase and cleaved caspase 3, demonstrating cholangiocyte lipoapoptosis. Interestingly, treatment with PA significantly increased the levels of microRNA miR-34a, a pro-apoptotic microRNA known to be elevated in NASH. …

Neuropilins (NRPs) are non-tyrosine kinase cell surface glycoproteins expressed in all vertebrates and widely conserved across species. The two isoforms, such as neuropilin-1 (NRP1) and neuropilin-2 (NRP2), mainly act as coreceptors for class III Semaphorins and for members of the vascular endothelial growth factor family of molecules and are widely known for their role in a wide array of physiological processes, such as cardiovascular, neuronal development and patterning, angiogenesis, lymphangiogenesis, as well as various clinical disorders. Intriguingly, additional roles for NRPs occur with myeloid and lymphoid cells, in normal physiological as well as different pathological conditions, including cancer, immunological disorders, …
