Abstract

It is well established that altered expression of microRNAs (miRs) is critical in numerous human cancer types. Nevertheless, the molecular mechanisms of many miRs are yet to be elucidated. In the present study, reverse transcription‑quantitative polymerase chain reaction and western blot analyses, and cell migration assays were performed to verify dysregulation of miR‑373 in melanoma and its biological function. The transcriptional level of miR‑373 was identified to be upregulated in melanoma tissues and cell lines compared with nevus and normal melanocytes. miR‑373 was identified to function as an oncomiR, promoting melanoma cell migration. Notably, miR‑373 was observed to suppress its downstream gene salt‑inducible kinase 1 (SIK1) through directly binding the 3'‑untranslated region of SIK1 expression. Furthermore, reduced SIK1 expression was identified to be responsible for the oncogenic effect of miR‑373. In conclusion, the present study indicates that miR‑373 functions as an oncomiR to promote melanoma progression through targeting SIK1 expression. This may provide a new therapeutic approach for melanoma.
