Graphic representation of the role of the miR-331-3p/MGAT1 axis in OS malignancy. MiR-331-3p suppressed MGAT1 expression, which resulted in decreased c-myc and Cyclin D1 proteins and decreased OS cells proliferation ability. MiR-331-3p decreased MGAT1 expression, which resulted in an increase in Bax and a decrease in Bcl-2, which was associated with an increase in OS cells apoptosis. Furthermore, miR-331-3p reduced MGAT1 expression levelby interacting with MGAT1 3’UTR, which resulted in decreased EMT, leading to a reduction in OS cells migration, invasion and metastasis capacities.
