Densitometric analyses of 3-7 Western blots are shown in Supplement Fig. S2 and demonstrate the differences among the cell lines, with the strong expression of Akt2 in PANC-1, A549, and H1299 cells and the very low expression of Akt3 in BxPC-3, COLO-357, PANC-1 pancreatic, and H2122 and HCC-44 lung carcinoma cells. Here, AKT3 is linked to lung carcinoma.
