Based on the weighted average (WA) method of scoring, GAS6 expression was stronger in epithelial ovarian cancers (EOC; n = 172) and ovarian borderline tumours (OBL; n = 40) than in ovarian surface epithelium (OSE; n = 6) or normal fallopian tubes (Tube; n = 3) (P = 4.97 × 10−5) (Figure 1(a)). Here, GAS6 is linked to ovarian carcinoma.
