  • Abstract:MicroRNAs are highly conserved noncoding RNA that negatively modulate protein expression at a posttranscriptional and/or translational level. MicroRNAs play an important role in the development and progression of human cancers, including osteosarcoma. Recent studies have shown that miR-100 was downregulated in many cancers; however, the role of miR-100 in human osteosarcoma has not been totally elucidated. In this study, we demonstrate that the expression of miR-100 was significantly downregulated in human osteosarcoma tissues compared to the adjacent tissues. Enforced expression of miR-100 inhibited cell proliferation, migration, and invasion abilities of osteosarcoma cells, U-2OS, and MG-63. Additionally, miR-100 also sensitized osteosarcoma cells to cisplatin and promoted apoptosis. Furthermore, overexpression of miR-100 decreased the expression of insulin-like growth factor I receptor and inhibited PI3K/AKT and MAPK/ERK signaling. In human clinical specimens, insulin-like growth factor I receptor was inversely correlated with miR-100 in osteosarcoma tissues. Collectively, our results demonstrate that miR-100 is a tumor suppressor microRNA and indicate its potential application for the treatment of osteosarcoma in future.
