All ETDs from UAB
The most common and most malignant gliomas are the Grade IV Glioblastoma Multiforme (GBM), characterized by a highly proliferative tumor mass and extremely invasive phenotype that allows for profuse dispersal of tumor cells throughout the brain. GBM cells must specifically regulate their cell volume to thrive within the edematous tumor mass and infiltrate throughout the tortuous extracellular spaces of the brain. These rapid and directed volume changes are governed by the controlled flux of potassium and chloride ions across the cell membrane, which move osmotically obliged water. The goal of this dissertation was to investigate the role of calcium-activated potassium …
