=====Kainic acid===== Kainic acid (KA) is an excitotoxic agent commonly used to induce [[epilepsy]] in [[rodent]]s. The relationship between KA-induced neuronal damage and Golgi complex fragmentation has not been investigated, leaving a major gap in our understanding of the molecular mechanism underlying the development of pathophysiology in epilepsy. Kaneko et al cultured primary [[rat]] [[cortical neuron]]s either in ambient condition (control) or treated with a range of KA doses to reveal whether [[Golgi complex]] fragmentation impaired neuronal function. The half-life maximal inhibitory concentration (IC 50) value of KA was detected to be approximately 5 μM, whereby at these concentrations, KA impaired neuronal viability, which was closely associated with initial Golgi complex fragmentation and subsequent reduction in both the expression and glycosylation patterns of [[Reelin]]. These findings implicate that Golgi complex fragmentation and Reelin dysfunction are key contributors to neuronal cell death in the early stage of epilepsy pathophysiology, thereby representing as novel disease [[biomarker]]s, as well as potent therapeutic targets for epilepsy ((Kaneko Y, Sullivan R, Dailey T, Vale FL, Tajiri N, Borlongan CV.
