SPINT1 and endometrial carcinoma: Pearson's correlation analysis of the migration distance and matriptase and HAI-1 expression levels in the three endometrial carcinoma cell lines treated with various cisplatin concentrations showed strong correlation (matriptase: r = 0.873, 0.743, and 0.824 in HEC-1A, HEC-1B, and RL-952 cells, respectively, P < 0.01; HAI-1: r = 0.934, 0.830, and 0.824 in HEC-1A, HEC-1B, and RL-952 cells, respectively, P < 0.01).
