  • Title: miR-411 contributes the cell proliferation of lung cancer by targeting FOXO1.
    Author: Zhao Z, Qin L, Li S.
    Journal: Tumour Biol; 2016 Apr; 37(4):5551-60. PubMed ID: 26572153.
    Abstract:
    Lung cancer is the leading cause of cancer deaths worldwide; the study of microRNAs gives new hope for lung cancer treatment. miR-411 has been demonstrated to be an independent prognostic factor for lung adenocarcinoma, but the role and regulatory mechanism are largely unknown. In the present study, we found miR-411 was overexpressed in the lung cancer cells; overexpression of miR-411 promoted anchorage-dependent and anchorage-independent growths of lung cancer, while miR-411 knockdown reduced this effect. Further study showed forkhead box O1 (FOXO1) was a target of miR-411. Overexpression of miR-411 suppressed the expression of FOXO1; the effect of suppression was abrogated when the mutation occurred in the 3'UTR of FOXO1. Knockdown of FOXO1 in cells which miR-411 was inhibited recapitulated the phenotype of miR-411 overexpression. Taken together, our study revealed miR-411 promoted cell proliferation of lung cancer by targeting tumor suppressor gene FOXO1 and miR-411 might be a potential target for lung cancer therapy.
