Chmp1 Negatively Regulates Epidermal Growth Factor Signaling In The Drosophila Wing, Meagan Elisabeth Valentine
Chmp1 Negatively Regulates Epidermal Growth Factor Signaling In The Drosophila Wing, Meagan Elisabeth Valentine
Theses, Dissertations and Capstones
A critical step in cellular signaling through transmembrane receptors is the down-regulation of activated receptors through the multivesicular body (MVB) pathway to the lysosome. MVB generation is mediated by the highly conserved ESCRT (0, I, II, and III) protein complexes. Though the ESCRT-III complex provides the core function of the ESCRT machinery, it is the least characterized of the ESCRT complexes. The Chmp1 protein is an ESCRT-III component and a putative tumor suppressor that has been linked to pancreatic and renal cancers in humans. However, published data on Chmp1 activity are conflicting and its role during tissue development is not …
Mda-9/Syntenin: From Glioblastoma Pathogenesis To Targeted Therapy, Timothy P. Kegelman
Mda-9/Syntenin: From Glioblastoma Pathogenesis To Targeted Therapy, Timothy P. Kegelman
Theses and Dissertations
The most common malignant glioma, glioblastoma multiforme (GBM), remains an intractable tumor despite advances in therapy. Its proclivity to infiltrate surrounding brain tissue contributes greatly to its treatment failure and the grim prognosis of patients. Radiation is a staple in modern therapeutic regimens, though cells surviving radiation become more aggressive and invasive. Consequently, it is imperative to define further the cellular mechanisms that control GBM invasion and identify promising novel therapeutic targets. Melanoma differentiation associated gene-9 (MDA-9/Syntenin) is a highly conserved PDZ domain-containing scaffolding protein that promotes invasion and metastasis in human melanoma models. We show that MDA-9/Syntenin is robustly …
Examining The Role Of G Protein-Coupled Estrogen Receptor 1 (Gper) Activation In 17beta-Estradiol-Mediated Protection In Traumatic Brain Injury, Nicole Day
All ETDs from UAB
Traumatic brain injury (TBI) affects millions of persons per year, potentially leading to permanent disability or death, and exacts a staggering financial toll. Despite the severity of this public health problem, there are no clinically proven pharmacotherapeutics available that effectively attenuate the secondary neurochemically-mediated damage that follows the initial biomechanical insult. In addition, the heterogeneous nature of TBI and complexity of secondary injury cascades suggest that a polytherapeutic approach could be a powerful strategy with which to simultaneously target more than one deleterious pathway. Recently, sex steroid hormones have sparked interest as possible neuroprotective agents after traumatic injury. One of …
