Rat pancreatic acinar cells and the whole cell lysates were processed as outlined in Figure 1 legend. Membranes were analyzed using anti-pY410 p130CAS, pY239/240 Shc, pY202/204 p42/44, pThr180/Y182 p38, pYThr183/Y185 JNK and pSer9 GSK3-β. Both a representative experiment of 3 others and the means of all the experiments are shown. * P< 0.05 vs control, # P< 0.05 vs PP2 alone, ∞ P< 0.05 vs PP3 alone and $ P< 0.05 comparing stimulants (CCK or TPA) vs stimulants pre-incubated with PP2 or PP3, respectively.
