What’s more, increased expression of miR-184-3p (Fig. 5m) and decreased expression of Cd206 (Fig. 5n) in tumor tissues in the miR-184-3p OE & hnRNPA2B1 KD group were confirmed by qRT-PCR, and the secretion of IL-10 detected by ELISA was also significantly reduced (Fig. 5o). The gene discussed is HNRNPA2B1; the disease is neoplasm.
