MiR-185 Inhibits the Proliferation and Invasion of Non-Small Cell Lung Cancer by Targeting KLF7.

ABSTRACT: MicroRNAs (miRNAs) are short endogenous noncoding RNAs that frequently play vital roles in many cancer types. Herein we demonstrated that miR-185 was remarkably downregulated in NSCLC tissues compared with adjacent normal tissues. A lower level of miR-185 was associated with lymph node metastasis. Functional assays showed that upregulation of miR-185 inhibited the proliferation, colony formation, and invasion capacities of NSCLC cells in vitro. Furthermore, we found that miR-185 suppressed the epithelial-mesenchymal transition (EMT) process. Bioinformatics analysis and luciferase reporter gene assays revealed that Kruppel-like factor 7 (KLF7) was the target of miR-185. Overexpression of miR-185 reduced the expression of KLF7 in NSCLC cells. Upregulation of KLF7 partly neutralized the inhib
