Research Abstract

We focused on DNase II as a candidate DNase executing autophagic cell death after hypoxic-ischemic (H-I) brain injury. To understand the molecular properties of DNase II, particularly the processing, we prepared a polyclonal antibody against mouse DNase II. Furthermore we succeeded in generating double knockout mice lacking both CAD (Caspase-activated DNase) and DNase II (CAD-/-DNase II mice). Using CAD-/-DNase II neonatal and adult mice, we examined H-I brain injury and found that DNA laddering was detectable in the ipsilateral hippocampus, indicating nuclear DNA in the damaged neurons was fragmented by a DNase other than CAD.
