Electroacupuncture activates the peroxisome proliferators-activated receptor pathway to improve the phenotype of cerebral palsy.

ABSTRACT

AIM: This study explores the efficacy of electroacupuncture (EA) in treating cerebral palsy (CP) in Sprague-Dawley (SD) pups, specifically CP animal models, and its molecular mechanisms. METHODS: Gait analysis and Y-maze were used to detect the improvement of motor ability and cognitive function of CP rats after EA treatment. Transcription sequencing was used to determine the key pathway for EA to improve the symptoms of CP. PPAR agonists were used to verify the causal relationship between the pathway and the improvement of CP phenotype. RESULTS: The motor ability and cognitive function of CP pups were improved after EA treatment. The results of transcriptome sequencing suggest that the improvement of CP phenotype may be caused by the activation of PPAR pathway. PPAR pathway is widely activated in the epithelium of CP pups treated with EA, which is verified by qPCR. Rosiglitazone (Ros), a PPAR agonist, can improve CP phenotype while activating PPAR pathway, which proves the causal relationship between PPAR pathway activation and CP phenotype improvement. CONCLUSION: Our study demonstrated behavioral improvements and enhanced cognitive functions in CP models after EA treatment by activating PPAR pathway, suggesting new perspectives for CP rehabilitation, and providing theoretical support for acupuncture treatment of CP.
