Association Between Ferroptosis and Epilepsy

8 de abril de 2022 actualizado por: Affiliated Hospital of Jiangnan University

Association Between GPX4 Dependent Ferroptosis Pathway and Epilepsy in School-aged Children

Epilepsy is one of the most common neurologic disorders seen in children, often characterized by recurring seizures. Nearly 10.5 million children worldwide are estimated to have active epilepsy. Children with epilepsy are more likely to have developmental health and developmental comorbidities such as depression, anxiety, attention deficit hyperactivity disorder, learning disabilities, and developmental delay compared to children without epilepsy. Status epilepticus (SE) is the most common life-threatening emergency neurological emergency in children and leads to hippocampal neuronal cell death. The animal model proved SE-induced neuronal cell death in hippocampal CA1 and CA3 regions. Classical drugs like carbamazepine or phenytoin often cause behavioral problems and side effects such as unsteady gait, depression, and irritability. In addition, classical medicine did not protect cognitive function and preferred to drive drug-resistant. Therefore, it is necessary to develop a novel therapy to treat epilepsy. Ferroptosis is a new type of cell death, usually accompanied by a large amount of iron accumulation and lipid peroxidation. It is widely accepted that glutamate-mediated neuronal hyperexcitation plays a causative role in eliciting seizures, and cystine/glutamate antiporter inhibition induces ferroptosis. Hence, investigators hypothesize GPX4 dependent ferroptosis pathway may play a key role in eliciting seizures.

Descripción detallada

To investigate the possible association between GPX4 dependent ferroptosis pathway and epilepsy. Investigators first obtained gene expression of GSE25453 from GEO (https://www.ncbi.nlm.nih.gov/geo), which contained ten medial temporal lobe epilepsy and ten adjacent non-seizure region tissues. Then, investigators further the possible association between GPX4 dependent ferroptosis pathway and epilepsy in school-aged children. Investigators obtained peripheral blood from 20 newly diagnosed untreated school-aged children (6 -12 years) and 20 age-matched healthy controls. Three glutathione peroxidase 4 (GPX4)dependent ferroptosis pathway biomarkers were investigated: Solute Carrier Family 7 Member 11(SLC7A11), GPX4, tumor protein 53 (P53). Western blot and Rt-qPCR were used to investigate the possible changes in these three biomarkers.
