The role of miR‐194 as a tumour suppressor in liver and gastric cancer as well as multiple myeloma was reported previously, and miR‐194 inhibits metastasis in lung cancer cells by targeting bone morphogenetic protein 1 and p27kip1 leading to the inactivation of TGFβ.30, 31, 32, 33. The gene discussed is TGFB1; the disease is lung carcinoma.
