ABSTRACT
BACKGROUND:
Increasing evidence has shown that the dysregulation of miRNAs is involved in the pathogenesis of retinoblastoma (RB). This present study was aimed to investigate the significance of miR-375 in RB progression, and the underlying mechanism. MATERIALS ANDMETHODS:
The miR-375 expression was detected by RT-PCR. CCK-8 assay and transwell assays were used to measure RB cell viability, migration, and invasion. The downstream gene of miR-375 was verified by luciferase reporter assay. Western blot was applied to detect the related proteins of MAPK1/MAPK3 signalling pathway.RESULTS:
MiR-375 was decreased significantly in RB tissues, and its down-regulation was associated with the poor prognosis of RB patients. Over-expression of miR-375 inhibited RB cell proliferation, migration, and invasion. More importantly, miR-375 modulated ERBB2 expression negatively, and ERBB2 was confirmed as the target of miR-375. Moreover, ERBB2 overturned the inhibitory effect of miR-375 mimic on the progression of RB. MiR-375 mimic suppressed RB progression via inhibiting the activation of MAPK1/MAPK3 signalling pathway.CONCLUSIONS:
MiR-375 inhibited RB progression through targeting ERBB2 and suppressing MAPK1/MAPK3 signalling pathway, which might be a new target for the clinical treatment strategy.Palavras-chave
