ST14 and ovarian carcinoma: We collected ovarian tissue from 18 clinical patients (9 cases of ovarian cancer and 9 cases of normal ovary tissue) to verify the expression of ST14 and TMEFF1 by western blot, and we found that the expression of ST14 and TMEFF1 in ovarian cancer was significantly higher than that in normal tissue (P both < 0.001; Fig. 1G-H).
