title: Effect of granatin B on the glioma cancer by inducing apoptosis.
abstract: Glioblastoma is a highly malignant cancer of glioma cells. Present study investigates the anti proliferative activity of granatin B on glioma cell by inducing apoptosis. In this study Glioma cell (U87) was used on which anti proliferative activity of granatin B (0, 20, 40 & 80 µM) assessed by 3-(4, 5-dimethylthylthiazol-2-yl)-2,5 diphenyltetrazolium bromide (MTT) assay. Thereafter Apoptosis of glioma cell was assessed by apoptosis detection kit suing flow cytometer, DAPI staining and by estimating the activity of caspase 3 & 9 using caspase 3 & 9 kit. Expression of MMP9 protein was determined through gelatin zymography. Possible mechanism of apoptosis induction was proved by estimating the effect of granatin B with MMP9 agonist on cell proliferation, caspase 3 activity & MMP9 expression on glioblastoma cell. Result of the study suggested that granatin B significantly decreases the cell proliferation of glioma cell compared to 0 µM treated group. It was also observed that treatment with granatin B significantly induces apoptosis and increases the activity of caspase 3 & 9 protein compared to 0 µM treated group. Expression of MMP9 protein was also decreases with granatin B treatment of glima cell. MMP9 agonist significantly reverses the effect of granatin B on cell proliferation, caspase 3 and expression of MMP9 protein in glima cell. Present study concludes the anticancer activity of granatin B on glioblastoma cell by inducing apoptosis.
