To reveal the role of Nuclelin (Ncl) downstream of mutant KRAS in shaping the proteome of Pancreatic Ductal Adenocarcinoma (PDAC) cells, we carried out a quantitative proteomics 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). Tandem Mass Tagging (TMT) was employed for quantitative analysis of Dox induced (24hrs) vs. non-induced iKras-PDAC cells, from control or Nucleolin depleted settings. Two independent siRNA oligos were used against Ncl. All samples barcoded and pooled together using TMT 6plex labelling kit (Thermo).
