KRT8 and neoplasm: The expression of human tumour compartment markers (Fig. 1b) was concordant with the known features of the tested cell lines: SK-BR-3 had the highest expression of Her2; MCF7, CAMA-1, T47D and ZR-75-1 had the highest expression of luminal proteins (ER and Keratin 8/18); MDA-MB-231 and MDA-MB-468 expressed the highest levels of basal/mesenchymal markers (EGFR and/or Vimentin) (Fig. 1b).
