We find that physiological levels of Kras(G12D) induce ductal lesions that recapitulate the full spectrum of human pancreatic intraepithelial neoplasias (PanINs), putative precursors to invasive pancreatic cancer.
Oncogene-directed increased expression of Nrf2 is a new mechanism for the activation of the Nrf2 antioxidant program, and is evident in primary cells and tissues of mice expressing K-Ras(G12D) and B-Raf(V619E), and in human pancreatic cancer.
Importantly, FGTI-2734 inhibited the growth of xenografts derived from four patients with pancreatic cancer with mutant KRAS (2 G12D and 2 G12V) tumors.
KRAS G12D point mutation plays an important role in the incidence of non-small-cell lung cancer (NSCLC) as well as colorectal cancer, pancreatic cancer and breast cancer.
