Role Of Transient Receptor Potential Channels In Epithelial Morphogenesis In Chick Embryo, Trinity Q. Waddell
Role Of Transient Receptor Potential Channels In Epithelial Morphogenesis In Chick Embryo, Trinity Q. Waddell
Theses and Dissertations
Transient Receptor Potential channels (TRP) are a superfamily of cationic specific ionchannels that are regulated by various stimuli such as temperature, pH, mechanical stress, ligandsand ion concentration. The role of TRP channels in disease states such as autosomal dominantpolycystic kidney disease, cancer metastasis, and developmental defects lend credence to thebelief that they play an important part in epithelial morphogenesis events. The development ofsomites, neural tube closure and migration of neural crest cells to form things such as the faceand heart is a good developmental model for the aforementioned cellular processes. We haveshown that TRP channels can be found in the …
Forward Chemical Genetics Drug Screen Yields Novel Proteases And Proteolytic Inhibitors Of Hgf–Induced Epithelial–Mesenchymal Transition, Jeffrey Thomas Schuler
Forward Chemical Genetics Drug Screen Yields Novel Proteases And Proteolytic Inhibitors Of Hgf–Induced Epithelial–Mesenchymal Transition, Jeffrey Thomas Schuler
Theses and Dissertations
Hepatocyte Growth Factor (HGF)–induced Epithelial–Mesenchymal Transition (EMT) is a complex cellular pathway that causes epithelial cell scattering by breaking cell–cell contacts, eliminating apical–basal polarity, and replacing epithelial markers and characteristics with mesenchymal markers. Early EMT events include a brief period of cell spreading, followed by cell compaction and cell–cell contact breaks. A forward chemical genetics drug screen of 50,000 unique compounds measuring HGF–induced cell scattering identified 26 novel EMT inhibitors, including 2 proteolytic inhibitors. Here, we show that B5500–4, one of the EMT inhibitors from the screen, blocks HGF–induced EMT by a predicted blocking of the protease furin, in addition …
Inhibition Of Pim And Axl Kinases As Potential Treatments For A Variety Of Hematological Malignancies And Solid Tumors, Kent James Carpenter
Inhibition Of Pim And Axl Kinases As Potential Treatments For A Variety Of Hematological Malignancies And Solid Tumors, Kent James Carpenter
Theses and Dissertations
This thesis is divided into three chapters. In each case, the goal is to achieve inhibition of a growth kinase (PIM or AXL) and subsequent arrest of cell growth and induction of apoptosis (in vitro cell culture models) or decrease in tumor volume (in vivo xenograft studies). Chapter one and chapter two discuss inhibition of proviral integration site for Moloneymurine leukemia virus (PIM) kinases. The three PIM kinases, PIM-1, PIM-2, and PIM-3, are a subfamily of serine/threonine kinases that are known to be involved in signaling pathways as downstream effectors of signal transducer and activator of transcription-5 (STAT5) signaling and …
