In the present study, we investigated the effect of 0, 5, 10, 20 and 40 uM NGF-related inhibitor Ro 08-2750; 0, 10, 100, 200 and 300 uM TrkA-related inhibitor K252a; and 0, 5, 10, 30 and 100 nM P75-related inhibitor LM11A-31 on the gene expression changes of β-catenin in ovarian cancer cells. The gene discussed is NTRK1; the disease is ovarian carcinoma.
