Abstract

It has previously been reported that KU60019, as a highly effective radiosensitizer, inhibits the DNA damage response and blocks radiation‑induced phosphorylation of key ataxia telangiectasia mutated targets in human glioma cells. The present study investigated whether KU60019 affects cell physiological activities and strengthens the efficacy of doxorubicin‑induced DNA damage. It was demonstrated that the compound suppressed the proliferation of MCF‑7 cells and significantly increased chemosensitization. In addition, KU60019 (without doxorubicin) inhibited MCF‑7 cell motility and invasion, potentially by acting on the phosphorylated‑Akt and E‑cadherin signaling pathways. Although the majority of MCF‑7 cells were arrested at the G1/S phase following treatment with KU60019, the combination of the two compounds did not result in such a marked effect on the cell cycle. In conclusion, KU60019 is a potent chemosensitizer in combination with doxorubicin, therefore, it may provide a promising strategy for non‑invasive breast cancer.
