Fig. 6From: Hypoxic resistance of KRAS mutant tumor cells to 3-Bromopyruvate is counteracted by Prima-1 and reversed by N-acetylcysteineDecreased GLUT1 external localization by Prima-1 and 3-BrPA exposed for 3Â h to hypoxia in A549 cells is not reverted by 2Â mM NAC. Inmmune fluorescence was used to analyze preferential cell surface (red arrows) or perinuclear localization (white arrows) in p-formaldehyde fixed and permeabilized cells, treated as indicated in each case under hypoxiaBack to article page
