DNMT1 and cancer: miR‐185 is a highly conserved microRNA encoded on human chromosome 22 and widely recognized as a tumor suppressor in multiple cancers, such as lung, liver, breast, and colorectal cancers.[25, 26]miR‐185 exerts its tumor‐suppressive effects by targeting oncogenes such as IGF1R, DNMT1, and components of the Wnt pathway.[25, 26] Consistent with these findings, we observed that miR‐185 inhibits NPC progression.
