EPCAM and neoplasm: To define the effect of RHOJ on protein expression in EMT tumour cells, we performed proteomics analysis of EPCAM+ and EPCAM− FACS-isolated primary tumour cells from Lgr5creERKrasG12Dp53cKORosa-YFP mice and YFP+EPCAM− cells that were transduced with viruses expressing control or Rhoj shRNA in untreated conditions and 24 h after cisplatin/5FU administration.
