ABT-737, a B cell lymphoma-2 (Bcl-2) family inhibitor, activates apoptosis in cancer cells. Arsenic trioxide is an apoptosis activator that impairs cancer cell survival. The aim of this study was to evaluate the effect of a combination treatment with ABT-737 and arsenic trioxide on uterine cervical cancer cells. MTT (3-(4,5-dimethylthiazol-2-yl)-25-diphenyltetrazolium bromide) assay revealed that ABT-737 and arsenic trioxide induced a synergistic effect on uterine cervical cancer cells. Arsenic trioxide enhanced ABT-737-induced apoptosis and caspase-7 activation and the ABT-737-mediated reduction of anti-apoptotic protein Mcl-1 in Caski cells. Western blot assay revealed that arsenic trioxide promoted the ABT-737-mediated reduction of CDK6 and thymidylate synthetase in Caski cells. Arsenic trioxide promoted ABT-737-inhibited mitochondrial membrane potential and ABT-737-inhibited ANT expression in Caski cells. However, ABT-737-elicited reactive oxygen species were not enhanced by arsenic trioxide. The combined treatment induced an anti-apoptosis autophagy in SiHa cells. This study is the first to demonstrate that a combination treatment with ABT-737 and arsenic trioxide induces a synergistic effect on uterine cervical cancer cells through apoptosis. Our findings provide new insights into uterine cervical cancer treatment.

Human papillomavirus (HPV) is the primary causative agent for the uterine cervical cancer. The expression of oncoproteins E6/E7 promotes apoptosis inhibition and increases the risk of cervical cancer progression. Some research reported that elevated expression of paxillin (PXN) stimulated cancer growth and invasion. However, the clinical significance of PXN in cervical cancer has not been well characterized so far. We found that PXN mRNA expression and protein level are significantly upregulated in cervical cancer cells compared to adjacent normal cells. Furthermore, the paxillin over-expression was correlated with potential of tumorigenesis and invasion. Cervical cancer cells with increased paxillin expression had an ability to form more tumor clones and were characterized by higher invasiveness as well. Therefore, our findings suggest that paxillin may act as an important prognostic factor for cervical cancer patients as it promotes tumor regeneration and invasion.
