Caloric Restriction and Ketogenic Diet Therapy for Epilepsy: A Molecular Approach Involving Pathway and K Channels

Epilepsy is a neurological disorder in which, in many cases, there is poor pharmacological control of seizures. Nevertheless, it may respond beneficially to alternative treatments such as dietary therapy, like the ketogenic diet or caloric restriction. One of the mechanisms of these diets is to produce a hyperpolarization mediated by the adenosine triphosphate (ATP)-sensitive potassium (K) channels (K channels). An extracellular increase of K prevents the release of Ca by inhibiting the signaling of the pathway and the translocation of β-catenin to the cell nucleus. ligands hyperpolarize the cells by activating K current by Ca. Each of the diets described in this paper has in common a lower use of carbohydrates, which leads to biochemical, genetic processes presumed to be involved in the reduction of epileptic seizures. Currently, there is not much information about the genetic processes implicated as well as the possible beneficial effects of diet therapy on epilepsy. In this review, we aim to describe some of the possible genes involved in pathways, their regulation through the K channels which are implicated in each one of the diets, and how they can reduce epileptic seizures at the molecular level.
