Abstract
Osteosarcoma is the most common primary malignancy to arise from bone. The pathogenesis of osteosarcoma is unclear, and new therapy molecular target is needed. The miRNAs researched suggested that miRNAs are involved in the pathogenesis of osteosarcoma. MiR-141, which belong to miR-200 family, take a part in tumorigenesis. However, the role of miR-141 in the pathogenesis of osteosarcoma remained unclear. In this study, we focused on the miR-141 in osteosarcoma and found that the expression of miR-141 is lower in osteosarcoma. Overexpression of miR-141 not only inhibits osteosarcoma cell proliferation but also induces cell apoptosis. It is estimated that miR-141 played its role via ZEB1 and ZEB2. In all, miR-141 played a osteosarcoma-suppressing role via ZEB1 and ZEB2. Our finding may elucidate the miRNAs mechanism in osteosarcoma and provide a new molecule target for osteosarcoma therapy.
