The clonal cell lines described (E, H, V, K, M, N and T) were isolated from pancreatic tumors from KPC mice and have been previously described30 . Clonal lines 6419c5, 6694c2, 2838c3 and 6499c4 were derived from KPC mice and have also been previously described24 (link). KPC7940B cells were a gift from G. Beatty (University of Pennsylvania). KPC-MT3 cells were a gift from D. Tuveson (Cold Spring Harbor Laboratory). PATC53 cells were obtained from ATCC. Cells were maintained in high-glucose DMEM (Gibco) supplemented with 10% fetal bovine serum (Corning) and routinely tested for mycoplasma contamination using MycoAlert Plus (Lonza). DMSO, oligomycin, phenformin and aminooxyacetic acid were obtained from Sigma, trans-ISRIB was obtained from Cayman Chemical and GCN2iB was obtained from MedChemExpress. IACS-10759 was obtained from Selleck Chem. KPC clonal lines were genotyped for KrasG12D recombination using primer sets from Jackson Laboratories.
