Abstract
miR-150 has been demonstrated to inhibit tumor progression in various human cancers, including colorectal
cancer, ovarian cancer, and thyroid cancer. However, the role of miR-150 in melanoma remains to be determined. In this study, we found that miR-150 was underexpressed in melanoma tissues and cell lines. Through
transfection of miR-150 mimics, we found that miR-150 significantly inhibited the proliferation, migration,
and invasion of melanoma cells. In mechanism, we found that MYB was a target of miR-150 in melanoma
cells. Overexpression of miR-150 significantly inhibited mRNA and protein levels of MYB in melanoma cells.
Moreover, there was an inverse correlation between the expression of miR-150 and MYB in melanoma tissues.
We also showed that MYB was upregulated in melanoma tissues and cell lines. Through functional experiments, we found that restoration of MYB in miR-150-overexpressed melanoma cells rescued the proliferation, migration, and invasion. Therefore, our findings demonstrated that miR-150 suppressed the proliferation,
migration, and invasion of melanoma cell by downregulating MYB.
