a Schematic and (b) RPPA heat map data showing increased pMEKS127, pERKT202/Y204, pAKTT308, and decreased expression of pAKTS273 in lysates from WT, cKrasMod, and cKrasHigh pancreata. c Quantification of RPPA relative expression data. d IHC analysis of pAKTT308 and pERKT202/Y204 in WT, cKrasMod and cKrasHigh pancreata confirms RPPA data that pAKTT308 and pERKT202/Y204 are significantly increased in cKrasMod and cKrasHigh pancreata relative to cKrasLow. e Western blot analysis of downstream signaling pathways in WT, cKrasLow, cKrasMod, and cKrasHigh cultured pancreatic ducts. f Quantification of western blot data normalized to vinculin. g Heatmap and (h) quantification for PTEN relative expression in WT, cKrasMod, and cKrasHigh mice. (i) IHC staining for PTEN of pancreata from cKrasLow, cKrasMod, and cKrasHigh mice (Zoomed in ×40 magnification images in inset). PTEN expression in normal ducts can be seen in cKrasLow, cKrasMod, and cKrasHigh mice. Scale bars are 50 µM.
