NTRK1 and ovarian carcinoma: A comparison between basal conditions of A2780 cells (epithelial ovarian cancer cell line) and HOSE cells (epithelial cells from human inactive ovary) show that miR-23b levels are lower in the A2780 cell line (Figure 3B, p < 0.05), suggesting that the higher expression of NGF and TRKA in A2780 cell line could affect miR-23b levels.
