I blog on anything to do with stroke. DO NOT DO ANYTHING SUGGESTED HERE AS I AM NOT MEDICALLY TRAINED, YOUR DOCTOR IS, LISTEN TO THEM. BUT I BET THEY DON'T KNOW HOW TO GET YOU 100% RECOVERED. I DON'T EITHER BUT HAVE PLENTY OF QUESTIONS FOR YOUR DOCTOR TO ANSWER.
Cerebral ischemia-reperfusion injury (CIRI) is a brain injury that usually occurs during thrombolytic therapy for acute ischemic stroke and impacts human health. Oxidative stress is one of the major causative factors of CIRI. DhHP-3 is a novel peroxidase-mimicking enzyme that exhibits robust reactive oxygen species (ROS) scavenging ability in vitro. Here, we established in vitro and in vivo models of cerebral ischemia-reperfusion to mechanistically investigate whether DhHP-3 can alleviate CIRI. DhHP-3 could reduce ROS, down-regulate apoptotic proteins, suppress p53 phosphorylation, attenuate the DNA damage response (DDR), and inhibit apoptosis in SH-SY5Y cells subjected to oxygen-glucose deprivation/re-oxygenation (OGD/R) and in the brain of Sprague Dawley rats subjected to transient middle cerebral artery occlusion. In conclusion, DhHP-3 has bioactivity of CIRI inhibition through suppression of the ROS-induced apoptosis.
