Abstract
We previously reported that Kras-driven Y1 tumor cells exhibit an unlikely association of high basal levels of K-Ras-GTP with cell cycle arrest by Fibroblast Growth Factor 2 (FGF2). Furthermore, in Y1 cells, experimental ectopic expression of an inducible dominant negative mutant, Ras-N17, reduced K-Ras-GTP basal levels and rescued FGF2 mitogenic activity (Costa et al. 2008; Salotti et al…
