TrkC was markedly induced in ES (A4753, RE-DS, STA-ETA, TC252, TC71, VH67, WE68, and CADO-ES1), breast (Hs578T and SUM159), and colorectal (SW480 and WiDr) cancer cell lines compared to its normal (human mammary epithelial cell (HMLE), MCF10A, CCD-112CoN, and CCD-841 CoN), which do not express TrkC (Fig. 1B). This evidence concerns the gene NTRK3 and cancer.
