GREB1 and ESR1 expression in epithelial ovarian cancers. a GREB1 and ESR1 mRNA were examined by QPCR in snap-frozen ovarian tumours, with gene expression normalized to PPIA (N = 4–5 per subtype). Very low expression was seen in four early-passage cultures of human ovarian surface epithelial cells. b In a tissue microarray of four major EOC histological subtypes (N = 20 each), GREB1 was expressed with similar proportions across all subtypes and did not correlate with ESR1 expression (see Fig. 7).
