The results showed that the expression of M2 markers (CD206, arginase-1, IL10, and CD163) in PMA-treated THP-1 cells administered exosomes derived from CRC cells transfected with anti-miR-934 or miR-934 mimics were apparently lower or higher, respectively, than that in the control groups (Fig. 3j, k). The gene discussed is MRC1; the disease is colorectal carcinoma.
