Importantly, FGTI-2734 inhibited the growth of xenografts derived from four patients with pancreatic cancer with mutant KRAS (2 G12D and 2 G12V) tumors.
K-ras<sup>LSL-G12D/+</sup>:: p53<sup>LSL-R172H/+</sup>:: Pdx-1-Cre (KPC) mice are an established model of pancreatic cancer that specifically express mutants of both K-ras and p53 in the pancreas by using Pdx-1-Cre.
The concomitant expression of oncogenic Kras(G12D) and mutant p53 (Trp53(R172H)) in the murine pancreas results in metastatic PDA that recapitulates the cognate features of human pancreatic cancer providing an excellent animal model to identify genes required for tumor progression.
Using the whole-cell recording mode of the patch-clamp technique, functional ion channels were electrophysiologically characterized in PANC-1 (K-ras G12D (+/-), p53 R273C, Deltap16), BxPC-3 (smad4-, p53 Y220C, Deltap16), and MiaPaCa-2 [transforming growth factor-beta receptor type II defect, K-ras G12C(-/-), p53 R248W, Deltap16] human pancreatic cancer cell lines.
