Method

293T or A-498 cells were transfected with 50 ng wild-type or mutant luciferase reporters and miR-520h mimics/miR-NC and pcDNA3.1-c-Myb/pcDNA3.1, along with 10 ng Renilla luciferase vector with the PEIpro reagent, respectively. After 48 h, luciferase activity was detected.

Abstract

Renal cell carcinoma (RCC) is the third most common urological cancer with highly metastatic potential. MAGI1 plays an important role in stabilization of the adherens junctions and has been confirmed to suppress invasiveness and metastasis in multiple cancers in clinic. However, its expression and anti-metastatic ability in RCC are still unclear. In this study, we demonstrated that MAGI1 was markedly decreased in the RCC and indicated poor survival. Furthermore, we found that MAGI1 suppressed the invasion and migration of human RCC cells. Mechanistic investigations revealed that MAGI1 stabilized the PTEN/MAGI1/beta-catenin complex to inhibit beta-catenin signaling pathway. Moreover, MAGI1 was targeted by miR-520h which was transcriptionally activated by c-Myb. Collectively, our findings suggested that MAGI1mediated tumor metastasis through c-Myb/miR-520h/MAGI1 signaling pathway in RCC.
