Docosahexaenoic Acid Alleviates Oxidative Stress-Based Apoptosis Via Improving Mitochondrial Dynamics in Early Brain Injury After Subarachnoid Hemorrhage.

ABSTRACT: Mitochondrial dysfunction is considered a crucial therapeutic target for early brain injury following subarachnoid hemorrhage (SAH). Emerging evidence indicates that docosahexaenoic acid (DHA), an essential omega-3 fatty acid, protects mitochondria in various chronic diseases. This study aimed to investigate the neuroprotective effects of DHA on mitochondrial dynamic dysfunction after EBI using in vivo and in vitro approaches. For in vivo experiments, the rat endovascular perforation SAH model was performed, whereby DHA was administered intravenously 1 h after induction of SAH. Primary cultured neurons treated with oxyhemoglobin (OxyHb) for 24 h were used to mimic SAH in vitro. Our results demonstrated that DHA improved neurological deficits and reduced brain edema in rats with SAH, and at
