The purpose of this study was to evaluate the anticancer efficacy of interferon β in combination with low dose of cisplatin on human cervical cancer progression, as well as its principal action mechanism. The combination treatment synergistically potentiated the effect of interferon β on cell growth inhibition and DNA damage on HeLa cells by repressing NF-κB/p-Akt signaling. Synergistic targeting of these pathways has a therapeutic potential. Further, the combination treatment ameliorated the expression of pro-apoptotic Bax, and decreased the expression of anti-apoptotic protein Bcl-2. Additionally, the expression of active PARP was significantly increased and MMP-9 level was decreased in combination group as compared to the expression seen for the treatment with interferon β or cisplatin alone. Results demonstrate that the synergistic inhibitory effects of interferon β and low dose of cisplatin on human cervical cancer cells and also suggest that the inhibition of NF-κB/p-Akt signaling pathway plays a critical role in the anticancer effects of combination treatment along with the induction of PARP. Therefore, the combination of interferon β and cisplatin may be a useful treatment for human cervical cancer, with a greater effectiveness than other treatments.
