MiR-26a enhances metastasis potential of lung cancer cells via AKT pathway by targeting PTEN

► miR-26a level is higher in metastasis tumor tissues than in primary tumor tissues. ► miR-26a enhances lung cancer cell migration and invasion. ► miR-26a modulates metastasis-related gene expression. ► miR-26a activates AKT pathway by PTEN suppression.
