In colorectal cancer (CRC), miR-17-5p was shown to be highly expressed in CAF exosomes that were transferred to tumour cells leading to targeting of RUNX3 (RUNX family transcription factor 3) which was demonstrated to effect the interaction with MYC and subsequent binding to the TGF-β1 (transforming growth factor beta 1) promoter leading to pathway activation and tumour progression [74]. Here, MYC is linked to neoplasm.
