Background: Despite the correlation between changes in the levels of apurinic/apyrimidinic endonuclease/redox effector factor-1 (APE/Ref-1), the DNA base excision repair protein, and ischemic neuronal damage, no studies have addressed the question of whether the overexpression or restoration of APE/Ref-1 may prevent ischemic neuronal cell death in vivo. Therefore, we investigated whether increasing APE/Ref-1 may inhibit the loss of APE/Ref-1 and DNA fragmentation, and prevent neuronal cell death after cerebral ischemia/reperfusion (I/R). Methods: Adult male C57BL/6J mice were subjected to intraluminal suture occlusion of the middle cerebral artery for 1 hour followed by reperfusion. Pre-ischemic treatment of the adenoviral vector harboring an entire APE/Ref-1 gene sequence was introduced intrastriatally. Immunohistochemistry assays in AP sites, and TUNEL were performed. Results: APE/Ref-1 was overexpressed by using adenoviral-vector-mediated APE/Ref-1 in striatum. Pre-ischemic administration of the Adenoviral vector harboring an APE/Ref-1 gene, by 4 or 24 hours after reperfusion, significantly decreased AP site and 8-OHdG, and subsequent inhibited the induction of apoptotic DNA fragmentation at 24 hours after I/R. Conclusion: The overexpression of APE/Ref-1 can prevent induction of apoptotic cell death after I/R. Using adenoviral-vector-mediated APE/Ref-1 could represent a molecular target for prevention of ischemic neuronal cell death.
