GPC1 and colorectal carcinoma: Although miR‐96‐5p and miR‐149 may regulate many genes and these genes may also be involved in the tumour growth, the regulatory effect of these two miRNAs on the secretion of GPC1 positive exosomes supports the feasibility of using CRC cell cultures for future mechanism studies of exosome release from cells and obtaining large amounts of exosomes for therapeutic purposes.
