MiRNome of epileptic children suggests the involvement of antioxidant pathways in the neuroprotective role of ketogenic diet

2018

Ketogenic diet (KD) has been used as treatment for refractory epilepsy in children since the 1920s. However, the neuroprotective mechanism of this diet is still unknown. Recent evidence points to a multifactorial effect of KD that involves a decrease of oxidative stress. Mononuclear cells from 14 children with refractory epilepsy, from the Paediatric Hospital “Nino Jesus” in Madrid, were obtained before and after treatment with a ketogenic diet for 6 months. A global analysis of miRNA expression (miRNome) indicates that there are 230 miRNAs which are expressed differently before and after the treatment with KD. If additionally, we restrict the miRNAs with a fold change > |1.3|we obtain 11 r…
