NTRK3 and colorectal carcinoma: In this study, we found the NTRKs gene promoter was more frequently methylated in CRC compared to normal mucosa, which was associated with suppressed expression of NTRK2 and NTRK3. Through a screen of probes targeting NTRKs gene, we identified a specific methylated region within NTRK3 promoter targeted by cg27034819 and cg11525479 that was the most promising prognostic marker for CRC.
