AKT1 and Hyperinsulinemia: In conclusion, this study demonstrated that insulin regulated MMP‐2 gelatinolytic activity via its “metabolic” PI3K/AKT and “mitogenic” ERK1/2 signalling pathways in immortalized human pancreatic ductal cell lines, as well as the synergistic effect of hyperinsulinemia and KRAS mutation in the early stage of pancreatic cancer.
