So the objective of this study is to apply antisense oligonucleotide for Livin gene to investigate the effect of inhibition Livin expression on proliferation and apoptosis of human bladder cancer cell 5637 in vivo and in vitro, and to further explore the mechanisms under the phenomenon, and to provide a theoretical basis for treatment of bladder cancer using antisense oligonucleotide with Livin as a target gene. This evidence concerns the gene BIRC7 and urinary bladder cancer.
