Lung cancer is the most common type of cancer and the leading cause of death in worldwide. MicroRNAs are known to be key players in a variety of biological processes, including tumorigenesis. In present study, we investigated the effect of miR-361-5p on lung cancer progression. We found that miR-361-5p was down-regulated in lung cancer. Overexpression of miR-361-5p suppressed lung cancer proliferation and invasion. Mechanistically, FOXM1 was identified as a direct target of miR-361-5p. Furthermore, miR-361-5p inhibits EMT-like phenotype through down-regulation of FOXM1 expression in lung cancer cells. In conclusion, our results indicated that miR-361-5p acts as a tumor suppressor in lung cancer.
肺癌是最常见的癌症类型,也是全球范围内导致死亡的主要原因。miRNAs 被认为是多种生物过程中的关键参与者,包括肿瘤发生。在本研究中,我们研究了 miR-361-5p 对肺癌进展的影响。我们发现 miR-361-5p 在肺癌中下调。miR-361-5p 的过表达抑制肺癌的增殖和侵袭。在机制上,FOXM1 被鉴定为 miR-361-5p 的直接靶标。此外,miR-361-5p 通过下调肺癌细胞中 FOXM1 的表达来抑制 EMT 样表型。总之,我们的结果表明 miR-361-5p 作为肺癌中的肿瘤抑制因子发挥作用。
