Abstract
Ovarian cancer poses a significant therapeutic challenge owing to the lack of specific targets for treatment. New treatment strategies are needed to improve patient outcomes and reduce the toxicity of existing therapies. This study aimed to investigate the synergistic effects of recombi-nant human apurinic/apyrimidinic endonuclease 1/redox factor 1 (rhAPE1/Ref-1) and aspirin on PEO14 and CAOV-3 ovarian cancer cells and human umbilical vein endothelial cells (HUVECs). Specifically, this study examined the mechanisms underlying the effect of rhAPE1/Ref-1 and as-pirin on cell death and the associated pathways. Cell viability was assessed using the MTT assay, and flow cytometry analysis and caspase-3/7 activity assays were conducted to determine apop-tosis. Western blotting was performed to evaluate the cleavage of poly(ADP-ribose) polymerase (PARP). Exposure to aspirin (3 mM) for 24 h did not affect cell viability in PEO14. Co-incubation of aspirin with rhAPE1/Ref-1 in PEO14 cells led to rhAPE1/Ref-1 acetylation and intracellular hyperacetylation. Co-treatment with aspirin (3 mM) and rhAPE1/Ref-1 induced a rhAPE1/Ref-1 concentration-dependent increase in cell death, particularly in PEO14 cells, as well as apoptosis, caspase-3/7 activation, and PARP cleavage. Furthermore, this combination treatment significantly increased paclitaxel-induced PEO14 cell death. Therefore, co-administration with rhAPE1/Ref-1 and aspirin is a potential strategy for ovarian cancer treatment.
