Abstract

Dysregulation of miR‑92a‑3p has been shown to contribute to many tumorigenic processes, and is correlated with tumor progression and prognosis. However, the association between miR‑92a‑3p and the clinicopathological features of Wilms tumorand its regulatory mechanism remain unknown. In the present study, we demonstrated that miR‑92a‑3p was downregulated in Wilms tumor tissues and was significantly correlated with the lung metastasis of patients with Wilms tumor. Furthermore, miR‑92a‑3p mimics suppressed Wilms tumor cell proliferation, migration and invasion by in vitro assays. In addition, miR‑92a‑3p knockdown promoted tumor progression. Moreover, miR‑92a‑3p was shown to target directly the 3'‑UTR of NOTCH1 mRNA by Dual‑Luciferase reporter assays in Wilm's tumor cells. miR‑92a‑3p mimics decreased the expression of mRNA and protein of NOTCH1. miR‑92a‑3p inhibitor enhanced NOTCH1 expression by using western blotting and qPCR. In Wilms tumor tissues, NOTCH1 was highly expressed when compared with that in adjacent non‑tumor tissues. NOTCH1 expression was found to be negatively correlated with miR‑92a‑3p in tumor tissues. Knockdown of NOTCH1 expression reversed the promotive effect of miR‑92a‑3p inhibitor on the cell proliferation, migration and invasion in Wilms tumor. In conclusion, miR‑92a‑3p blocks the progression of Wilms tumor by targeting NOTCH1.
