Aims
We aimed to elucidate the effects and mechanisms of MAT1 in the progression of osteosarcoma, especially for its lung metastasis. Main
Methods
CCK-8 and flow cytometry assays were carried out to detect the proliferation and apoptosis of osteosarcoma cells. Wound healing and transwell assays were used to determine cell migration and invasion abilities. Real time quantitative PCR (RT-PCR) and western blot technologies were applied to detect the expression levels of RNA and protein, respectively. Key finds: The
Significance
This study reveals that high expression of MAT1 closely related to the poor prognosis and malignant clinical process of osteosarcoma patients. MAT1 serves as a promoter in the lung metastasis of osteosarcoma through increasing AKT1 expression. Our study may provide a potent therapeutic target for the lung metastasis of osteosarcoma.
