摘要:Oral squamous cell carcinoma (OSCC) is a malignant solid tumor characterized by hypoxia. Autophagy is considered to play a protective role in cancer cells under hypoxia. A variety of microRNAs (miRNAs) that play a critical role in tumorigenesis have been identified. However, the underlying mechanisms of miR-150 in OSCC development remain unclear. In this study, we observed decreased downregulated expression of miR-150 in association with increased expression of BNIP3 in CAL-27 cells under hypoxia. Hypoxia induced the initiation of the BNIP3-mediated autophagic process, and overexpression of miR-150 inhibited hypoxia-induced autophagy. In addition, we demonstrated that miR-150 inhibited autophagy by negatively regulating the expression of the BNIP3 gene. Collectively, our study identified miR-150 as a key modulator of autophagy by inhibiting BNIP3 in OSCC cells.
