Regulation Of Glioma Cell Migration And Proliferation By A Non-Selective Cation Channel., Arun Kumar Rooj

Two of the most striking features of brain tumors are their unusual ability to robustly proliferate and migrate in the brain. Previous results from our laboratory suggest that glioma cells express a non-selective cation channel that is composed of Epithelial Sodium Channel (ENaC) and Acid Sensing Ion Channel (ASIC) subunits. We hypothesize that this glioma specific current regulates glioma cell migration and proliferation by modulating an intracellular signaling pathway. To test our hypothesis, we have attenuated this cationic conductance by either pharmacological blockers (psalmotoxin-1 and benzamil), or by knocking down expression of a particular subunit of this cross-clade ion channel …

Malignant gliomas are highly invasive brain tumors, which lack effective treatment options. To date, the standard therapy includes surgical debulking followed by chemotherapy and radiation. Despite efforts to eradicate the disease, the median patient survival time is only 14 months. In an attempt to discover novel therapies, research has focused on understanding the heterogeneous biological mechanisms employed by these cells. Uniquely, they do not metastasize through the vasculature or lymphatics like other solid cancers but alternatively, glioma cells utilize the abluminal surface of the vasculature to guide invasion and migration throughout the brain. The intimate association between glioma cells and …
