| Notes | 37-1156/R Objective To investigate the effects of suppressor of cytokine signaling-1（ SOCS1） gene silencing on cell proliferation,invasion and chemotherapeutic drugs sensitivity of human bladder cancer cells. Methods Human bladder cancer cell line T24 cells were randomly divided into three groups： the interference group（ which was transfected by recombinant plasmid p U-SOCS1-siRNA）,control group（ which was transfected by negative control plasmid） and blank group without any treatment. RT-PCR and Western blotting were used to detect the SOCS1 mRNA and protein expression in human bladder cancer cell line（ T24） after transfection. The cell proliferation rate was detected by MTT assay,flow cytometry was used to detect the cell cycle and cell apoptosis rate; the invasive ability of T24 cells in vitro was evaluated by Transwell migration assay and the change of chemosensitivity was determined by MTT. Results Compared with the other groups,after silencing SOCS1 in the interference group,the expression levels of SOCS1 |
