These characteristics are in contrast to the expression pattern of phenotypic markers presented by the epithelial-like ovarian cancer cell lines Ovcar3 and Caov3 (high e-cadherin and MUC1 expression, no vimentin expression and a localization of actin to cell-cell junctions), and by the Skov3 cell line which presented a mixed pattern of marker expression (no e-cadherin expression, low MUC1 expression, considerable vimentin expression and a localization of actin to cell-cell junctions). The gene discussed is MUC1; the disease is ovarian cancer.
