However, some studies defined miR-211 as a tumor promoter, by inhibiting the expression of SRC kinase signaling inhibitor 1 (SRCIN1), miR-211 was proved to promote human non-small cell lung cancer [21], and by targeting tumor suppressive gene CHD 5, miR-211 can promote human colon cancer [22, 23]. The gene discussed is ENSG00000280371; the disease is colonic neoplasm.
