Syk Promotes Tgf-Beta-Induced P-Body Clearance In Breast Cancer Cells Through The Enhancement Of Autophagy, Shana D. Hardy
Syk Promotes Tgf-Beta-Induced P-Body Clearance In Breast Cancer Cells Through The Enhancement Of Autophagy, Shana D. Hardy
Open Access Dissertations
SYK is a protein tyrosine kinase that plays an essential role in the development and activation of immune cells. Its expression, however, is not limited to immune cells. SYK is expressed in a variety of epithelial cell types and epithelial-derived tumors. Reports regarding the role of SYK expression in these diverse cell types and tumors have been opposing. In breast cancer, SYK expression has been overwhelmingly associated with tumor suppression. The loss of Syk expression is observed in invasive breast carcinoma tissue and cell lines and the reintroduction of Syk into metastatic breast cancer cells suppresses tumor growth and metastasis. …
Inhibiting The Interaction Between Grp94 And Myocilin To Treat Primary Open-Angle Glaucoma, Andrew Stothert
Inhibiting The Interaction Between Grp94 And Myocilin To Treat Primary Open-Angle Glaucoma, Andrew Stothert
USF Tampa Graduate Theses and Dissertations
Glaucoma is a neurodegenerative protein misfolding disorder classified by increases in IOP, damage to retinal ganglion cells (RGCs), optic nerve (ON) head damage, and progressive irreversible blindness. Primary open-angle glaucoma (POAG) is the most common form of glaucoma, constituting over 90% of clinical cases. POAG is observed in patients where normal outflow channels, mainly the trabecular meshwork (TM), are exposed at the angle formed by the iris and cornea. However, due to TM cellular dysfunction, aqueous outflow resistance is increased preventing normal circulation of aqueous humor. Recent studies have shown that in 2-4% of POAG cases, increased intracellular levels of …
Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin
Targeting Tau Degradation By Small Molecule Inhibitors For Treatment Of Tauopathies, Mackenzie Martin
USF Tampa Graduate Theses and Dissertations
Tauopathies are neurodegenerative diseases that affect millions of people around the world. Tauopathies include more than 20 neurodegenerative diseases. Some of the most common tauopathies are Alzheimer’s disease (AD), frontotemporal dementia (FTD), chronic traumatic encephalopathy (CTE), Pick’s disease, corticobasal degeneration, progressive supranuclear palsy (PSP), agyrophillic grain disease, and amyotrophic lateral sclerosis (ALS). These diseases can cause significant memory loss, behavioral changes, motor deficits and speech impairments. Tauopathies stem from accumulation of the microtubule associated protein tau (MAPT). Tau stabilizes microtubules and helps with axonal transport. In a disease state tau becomes hyperphosphorylated and truncated leading to its aggregation. More recently …
Axonal Transport And Life Cycle Of Mitochondria In Parkinson's Disease Model, Hyun Sung
Axonal Transport And Life Cycle Of Mitochondria In Parkinson's Disease Model, Hyun Sung
Open Access Dissertations
In neurons, normal distribution and selective removal of mitochondria are essential for preserving compartmentalized cellular function. Parkin, an E3 ubiquitin ligase associated with familial Parkinson’s disease, has been implicated in mitochondrial dynamics and removal. However, it is not clear how Parkin plays a role in mitochondrial turnover in vivo, and whether the mature neurons possess a compartmentalized Parkin-dependent mitochondrial life cycle. Using the live Drosophila nervous system, here, I investigate the involvement of Parkin in mitochondrial dynamics; organelle distribution, morphology and removal. Parkin deficient animals displayed less number of axonal mitochondria without disturbing organelle motility behaviors, morphology and metabolic state. …
