This panel included colon tumour cell lines (SW480, SW620 and HT29); a lung tumor cell line (A549);breast tumour cell lines (MCF7, HCC1937, HCC1954 and MDA-MB-231); endometrial tumour cell lines (HEC1A and HEC1A-ETV5) anda prostate tumor cell line (PC-3).These tumour cell lines are all of epithelial origin; however, the SW620, MDA-MB-231 and PC-3 cell lines are from metastatic sites and have a more mesenchymal-like phenotype together with A549 and HEC1A-ETV5 cells[26, 29–32] (S1 Table). This evidence concerns the gene ETV5 and prostate neoplasm.
