Tgif1 Physiological Levels Limit Β-Cell Distress And Neonatal Diabetes, Creighton J. Friend
Theses and Dissertations
TGIF1 belongs to the superfamily of homeodomain proteins, which regulate a wide variety of biological functions, including cell stemness and specification of cell fate during early development. Perhaps surprisingly, we found that enforced expression in pancreatic progenitor cells during embryogenesis resulted in severe diabetes, hinting at the possibility that TGIF1 might regulate pancreas development. Subsequent genetic experiments targeting β-cells showed that TGIF1 affected β-cell function and homeostasis. Transcriptomic analysis revealed that TGIF1 expression inhibits the expression of essential components of UPR signaling, underscoring a potential mechanism in which TGIF1 disrupts protein folding and secretion. Congruently, TGIF1 expression led to a …
Modification Of Culture Medium And Identification Of Microbial Contaminants For Improved In Vitro Propagation Of Freshwater Mussels, Raquel M. Wetzell
Modification Of Culture Medium And Identification Of Microbial Contaminants For Improved In Vitro Propagation Of Freshwater Mussels, Raquel M. Wetzell
Theses and Dissertations
In vitro propagation efforts play an essential role in conserving and restoring threatened freshwater mussel populations by circumventing the need for a fish host. Across a broad range of taxa, transformation is induced with an artificial M199 medium and rabbit serum. However, such formulation may not be sufficient in culturing critical species with more specific physiological requirements. In this study, multiple serum mixtures were tested to improve in vitro transformation of two freshwater mussel species: yellow lampmussel (Lampsilis cariosa) and tidewater mucket (Atlantaconcha ochracea). These species were selected because they parasitize similar fish host species but …
The Role Of The Mechanical Environment On Cd117+ Endothelial Cell Angiogenesis, Patrick Link
The Role Of The Mechanical Environment On Cd117+ Endothelial Cell Angiogenesis, Patrick Link
Theses and Dissertations
Angiogenesis is a complex process coordinating cell migration, proliferation, and lumen formation. Changes to the microenvironment regulate angiogenesis through mechanotransduction and cytokine signals. In pulmonary hypertension, something in the process becomes abnormal, resulting in changes to the microenvironment and the formation of a glomerulus of dysfunctional capillaries, called a plexiform lesion. Endothelial cells, expressing CD117 (CD117+ EC clones) increase in the plexiform lesions of pulmonary hypertension, independent of pro-angiogenic VEGF signaling. We hypothesize that the mechanical environment and the macromolecular composition of the extracellular matrix, both, contribute to the aberrant angiogenesis. When we changed the mechanical environment, we changed the …
