Figure 1: GAS6 is overexpressed in ovarian cancers. (a) Box plot demonstrating GAS6 weighted average expression scores on various ovarian tissues as assessed by immunohistochemistry. Statistical test performed was the Kruskal-Wallis test. OSE: ovarian surface epithelium; CystA: cystadenoma; OBL: ovarian borderline tumour; EOC: epithelial ovarian cancer. (b) Western blots for GAS6 on a panel of ovarian cell lines. Left panel shows original blot, right panel shows relative expression based on densitometric analysis (density of GAS6 divided by density of GAPDH). Results from a representative experiment are shown. Normal cell lines (HOSE6.3 and HOSE17.1) are marked (framed or black bars).
