HGSOC cells can be characterized by mesenchymal/epithelial status. (A) mRNA expression levels of SNAI1 (Snail; black), CDH1 (E-cad; white), and CDH2 (N-cad; gray bars) in indicated lines relative to fibroblasts by qRT-PCR. β-actin was used for normalization. (B) RNA S/E index: qRT-PCR data from A were combined to describe the ratio between SNAI1 and CDH1 mRNA. (C) Protein levels of Snail and E-cad from Western blot (WB), normalized to α/β tubulin, relative to NCCIT. For each experiment, all samples were run on a single gel. Gels from independent experiments were analysed in parallel. (D) Protein S/E index: WB data from C were combined to describe the ratio between Snail and E-cad. (A–D) Data represent the mean of at least three independent experiments. Error bars, SEM. (E) DIC images of cell lines.
