Osteosarcoma, one of primary bone tumor in children and young adults, has poor prognosis and drug resistances to chemotherapy. In order to reinforce the conventional therapies and antagonize the osteosarcoma in patients, a novel strategy is required for developing a new treatment. In this study, surfactin, a natural product from Bacillus subtilis, showed the efficiency of cell death in osteosarcoma,...
Long noncoding RNA focally amplified lncRNA on chromosome 1 (FAL1) plays an important role in the development of several human malignancy entities. However, the expression and function of FAL1 in the carcinogenesis and development of osteosarcoma remain unknown. In this study, we detected the FAL1 levels in human osteosarcoma tissues and cell lines by quantitative real‐time polymerase chain reaction...
Osteosarcoma is a very malignant bone tumor which has a high metastatic potential and usually lead to poor prognosis. The adhesion of tumor cells to the endothelium or extracellular matrix (ECM) is an essential step in the metastatic cascade. We investigated the effect of thrombin on the adhesion activity of the osteosarcoma cell line, ROS 17/2.8. Incubation with the low concentrations of thrombin...
The interaction of extracellular matrix with cells plays a key role in the regulation of cell adhesion, migration, proliferation as well as differentiation. Transformed cells express a different profile of adhesion molecules, which may mediate metastasis under specific matrix microenvironment. We here found that ROS 17/2.8 osteosarcoma cells and osteoblasts have different expression of α5 integrin,...
