For example, by targeting TLR2, miR‐154 inhibits the ectopic proliferation and migration of CRC cells.26 Additionally, miR‐377, miR‐381, and miR‐409, another three members of the miR‐154 gene family, are involved in either invasion or drug sensitivity.27, 28 In this regard, as a member of the miR‐154 gene family, we have reasons to speculate miR‐487b is likely to play a role in cancer. This evidence concerns the gene TLR2 and cancer.
