Objective To investigate the effects of As_2O_3 on expression of NF-κB p65, survivin and caspase-3 in human breast infiltrating duct carcinoma xenograft model on nude mice. Methods A human breast infiltrating duct carcinoma model on nude mice was established and the nude mice were divided randomly into three groups: control group, DDP group and As_2O_3 group (1.5 and 3.0 mg/kg concentrations). The expression of survivin mRNA was detected with the method of in situ hybridization and the expressions of NF-κB ...
