WebGSH levels are significantly elevated in tissues and cells from Abcc1 −/− mice, and MRP1-overexpressing tumor cells have lower intracellular GSH levels and higher levels of GSH efflux (15, 47, 48). The lower GSH levels in cells expressing MRP1 reduce their antioxidant capacity and, by doing so, can render the cells more susceptible to ... WebOct 10, 2008 · The present review focuses on an analysis of links among GSH, adaptive responses to stress, molecular mechanisms of invasive cancer cell survival and death, and sensitization of metastatic cells to therapy. Experimental evidence shows that acceleration of GSH efflux facilitates selective GSH depletion in metastatic cells.
