Title: miR-215 promotes cell migration and invasion of gastric cancer cell lines by targeting FOXO1
Author: Y. Zang, T. Wang, J. Pan, F. Gao

Abstract: Gastric cancer is one of the most common malignant tumor worldwide and has high morbidity and mortality. microRNAs are small, non-coding RNAs which play critical roles in the post-transcriptional regulation of gene expression. In this current study, we used qRT-PCR to detect miR-215 and FOXO1 expression level in 50 paired gastric cancer tissues and found that miR-215 was frequently overexpressed and FOXO1 was down-regulated in GC cancer tissues. Clinicopathological analysis showed that miR-215 expression level was correlated with the progression of tumor invasion and TNM stage. Additionally, transwell invasion assay showed that miR-215 promoted the migration and invasion of gastric cancer cells. We found that miR-215 decreased FOXO1 expression by directly binding to the 3’-untranslated region (UTR) of FOXO1. These results suggest that miR-215 promotes cell migration and invasion of gastric cancer by targeting FOXO1. Therefore, this study provides a promising therapeutic strategy for treating gastric cancer.
