Niflumic acid inhibits the proliferation,migration and invasion of glioma U87 cells

AIM To investigate the effect of niflumic acid （NFA） on human glioma U87 cells and to clarify the potential mechanism. METHODS The U87 cells were cultured in vitro and divided into blank control group， and 50， 100 and 200 μmol/L NFA groups. MTT assay was performed to determine the viability of cells in various groups. Migration and invasion abilities were measured by real-time cell analysis （RTCA）. RESULTS The results of MTT assay showed that compared with blank control group， the viability of U87 cells was increased after treatment with NFA for 12 h （P<0.05 or P<0.01）， while the viability was significantly decreased after treatment with NFA for 24 and 48 h （P<0.05 or P<0.01） in a concentration-dependent manner. The results of RTCA showed that compared with control group， the cell migration and invasion abilities were inhibited in 100 and 200 μmol/L NFA groups （P<0.05 or P<0.01） and the inhibitory effects were more obvious in 200 μmol/L NFA group （P<0.01）. CONCLUSION NFA inhibits the viability， migration and invasion of human glioma U87 cells.
