Here, we intended to appraise the functional influence of microRNA-142-5p (miR-142-5p) in retinoblastoma. MiR142-5p was declined, and MYCN was upregulated in retinoblastoma tissues and cells. Moreover, miR142-5p restricted cell proliferation, migration, invasion, and enhanced cell apoptosis in retinoblastoma cells. MYCN was adversely controlled by miR-142-5p. Besides, the inhibition of miR-142-5p-mediated effects on retinoblastoma progression were blocked by MYCN overexpression in retinoblastoma cells. This research illustrated that miR-142-5p restricted retinoblastoma progression via interacting with MYCN. (c) 2021 Elsevier Inc. All rights reserved. 收起
