Investigating The Role Of Hydrogen Sulfide In The Survival, Growth And Angiogenic Potential Of Clear Cell Renal Cell Carcinoma Cell Lines And Xenografts, Eric Sonke
Electronic Thesis and Dissertation Repository
Clear cell renal cell carcinoma (ccRCC) is characterized by Von Hippel-Lindau (VHL)-deficiency, resulting in pseudohypoxic, angiogenic and glycolytic tumours. Hydrogen sulfide (H2S) is an endogenously-produced gasotransmitter that accumulates under hypoxia and has been shown to be pro-angiogenic and cytoprotective in cancer. It was hypothesized that H2S levels are elevated in VHL-deficient ccRCC, contributing to survival, metabolism, and angiogenesis. Using H2S-specific probes, it was found that H2S levels were higher in VHL-deficient ccRCC cell lines compared to cells with wild-type VHL. Inhibition of H2S-producing enzymes could reduce the proliferation, metabolism …
