Abstract

Ischemic stroke is a leading cause of global death. The treatment of this disease can inevitably result in reperfusion, thereby triggering cerebral ischemia-reperfusion injury (IRI) and neuronal pyroptosis. Electroacupuncture derived from traditional acupuncture has been proven to have favorable effects on ameliorating brain IRI and pyroptosis. Hence, the goal of the current research was to elucidate the mechanism governing electroacupuncture in cerebral IRI. We employed middle cerebral artery occlusion (MCAO) model to induce brain IRI. Our results revealed that electroacupuncture attenuated IRI in MCAO mice by minishing brain damage and hindering neuronal pyroptosis. Strikingly, it was discovered that electroacupuncture provoked the decrease of succinylation level and enhanced expression of SIRT5. Then, we demonstrated that knockdown of SIRT5 reversed the role of electroacupuncture in cerebral infarct injury and pyroptosis. In terms of mechanism, SIRT5 impeded the succinylation modification of NEK7 at K81 site to downregulate its expression level. Eventually, overexpression of NEK7 abrogated the impacts of electroacupuncture on MCAO mice. In conclusion, this study provided the compelling evidence that electroacupuncture restrained neuronal pyroptosis to mitigate ischemic brain damage via desuccinylating NEK7 in a SIRT5-dependent manner.

期刊介绍: The Brain Research Bulletin (BRB) aims to publish novel work that advances our knowledge of molecular and cellular mechanisms that underlie neural network properties associated with behavior, cognition and other brain functions during neurodevelopment and in the adult. Although clinical research is out of the Journal''s scope, the BRB also aims to publish translation research that provides insight into biological mechanisms and processes associated with neurodegeneration mechanisms, neurological diseases and neuropsychiatric disorders. The Journal is especially interested in research using novel methodologies, such as optogenetics, multielectrode array recordings and life imaging in wild-type and genetically-modified animal models, with the goal to advance our understanding of how neurons, glia and networks function in vivo.
