Methods: The telomerase activity in breast cancer cells and MRC-5 cell line were detected semi-quantitively by TRAP-ELISA assay. Virus proliferation as- say and cell viability assay were used to evaluate the proliferation and cytolysis selectivity of CNHK300, and the results were compared with those of wtAd5. The breast cancer cells were treated with CNHK300 combining paclitaxel to evaluate the killing effect of the combined regimen.
