To reveal the impact of mutant KRAS expression on the proteome of Pancreatic Ductal Adenocarcinoma (PDAC) cells, we carried out a timecourse quantitative proteomic analysis of tumour cells isolated from an inducible mouse model of PDAC (iKras PDAC) (Ying et al., 2012). In this model, oncogenic Kras (G12D) expression can be controlled by administration of doxycycline(Dox). Cells were grown in the absence of Dox for 48 hrs, before being treated with or without Dox for 4, 8, 12, 24, and 36 hrs, followed by total lysis and quantitative proteomics analysis using Tandem Mass Tagging (TMT). A total of 2 biological replicate experiments were analysed, with all samples from each replicate barcoded and pooled together using TMT 10plex labelling kit (Thermo).
