The Role Of Ca2+/Calmodulin Dependent Protein Kinase Ii, Camk-Ii, In Kidney Morphogenesis, Sarah R. Ingram
The Role Of Ca2+/Calmodulin Dependent Protein Kinase Ii, Camk-Ii, In Kidney Morphogenesis, Sarah R. Ingram
Theses and Dissertations
Autosomal dominant polycystic kidney disease (ADPKD) is one of the most common heritable diseases in the world, characterized by the development of large fluid filled cyst. Treatments for this disease are limited due to a lack of understanding of disease pathogenesis. Ca2+/calmodulin dependent protein kinase II (CaMK-II) is necessary for kidney morphogenesis in zebrafish as well as being a downstream effector of pkd2, one of the genes most commonly mutated in ADPKD patients. The roles of CaMK-II during zebrafish kidney development include regulation of kidney cell migration as well as cloacal cilia stability. The influence of CaMK-II …
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
The Impact Of Aging And Mechanical Injury On Alveolar Epithelial And Macrophage Responses In Acute Lung Injury And Inflammation, Michael S. Valentine
Theses and Dissertations
Patients with severe lung pathologies, such as Acute Respiratory Distress Syndrome (ARDS), often require mechanical ventilation as a clinical intervention; however, this procedure frequently exacerbates the original pulmonary issue and produces an exaggerated inflammatory response that potentially leads to sepsis, multisystem organ failure, and mortality. This acute lung injury (ALI) condition has been termed Ventilator-Induced Lung Injury (VILI). Alveolar overdistension, cyclic atelectasis, and biotrauma are the primary injury mechanisms in VILI that lead to the loss of alveolar barrier integrity and pulmonary inflammation. Stress and strains during mechanical ventilation are believed to initiate alveolar epithelial mechanotransduction signaling mechanisms that contribute …

The Human Intermediate Prolactin Receptor: A Breast Cancer Proto-Oncogene, Jacqueline M. Grible
Theses and Dissertations
The hormone prolactin (PRL) and its receptor (hPRLr) are significantly involved in breast cancer pathogenesis. The intermediate hPRLr (hPRLrI) is an alternatively-spliced isoform, capable of stimulating cellular viability and proliferation. An analogous truncated mouse PRLr (mPRLr) was recently found to be oncogenic when co-expressed with wild-type mPRLr. hPRLrI co-expression with full-length hPRLr (hPRLrL) in MCF10AT cells resulted in robust in vivo and in vitro transformation, while hPRLrI knock-down in MCF7 cells significantly decreased in vitro malignant potential. hPRLrL+I heterodimers displayed greater stability than hPRLrL homodimers, and while being capable of activating Jak2, Ras, and MAPK, they were unable to induce …
Higher Tensile Forces Across Cellular Junctions And An Intact Nuclear Linc Complex Is Required For Epithelial Function And Stability, Fnu Vani Narayanan
Higher Tensile Forces Across Cellular Junctions And An Intact Nuclear Linc Complex Is Required For Epithelial Function And Stability, Fnu Vani Narayanan
Theses and Dissertations
Recent advances in three-dimensional (3D) cell culture systems have provided key insights into the understanding of biochemical and physiological states of native tissue. A significant progress in the field of mechanobiology involves measuring cellular traction forces in a more native 3D environment. However, the effects of mechanical forces exerted across cellular junctions and the nuclear LINC complex, in an organized 3D system has not been investigated thus far. Epithelial cells spontaneously form acini (also known as cysts or spheroids) with a single, fluid-filled central lumen, when grown in 3D matrices. The size of the lumen is dependent on apical secretion …
Disruption Of The Dream Complex Results In Cell Cycle Deregulation, Hayley C. Walston
Disruption Of The Dream Complex Results In Cell Cycle Deregulation, Hayley C. Walston
Theses and Dissertations
The Dimerization Partner, Rb-like, E2F, And MuvB (DREAM) complex was identified in humans due to homology of the genes involved in the D. melanogaster dREAM complex. It assembles during cellular arrest, or G0, to function as a transcriptional repressor of cell cycle genes. It is known that phosphorylation of LIN52 at serine 28 is necessary for the critical DREAM forming interaction between LIN52 and the pocket protein p130. Our laboratory has previously shown that gene editing of LIN52 to replace serine 28 with alanine (S28A) prevents phosphorylation by the kinase DYRK1A and inhibits DREAM formation. Here we have confirmed this …
