HGF and lung cancer: miR‐1‐3p and miR‐206 have been identified as tumour suppressors in various human cancers, including lung cancer.6, 12, 17, 18, 23, 24 Exogenous expression of these two miRNAs could significantly reduce cell motility and invasiveness.25 In this study, we evaluated miR‐1‐3p and miR‐206 expression in HGF stimulation of PC‐9 and HCC827 cells.
