Abstract:
:Glypican-4 (Gpc4) has been found to play an important role in enhancing miniature excitatory postsynaptic currents (mEPSCs). But, the relationship between Gpc4 and epilepsy is still a mystery. In this study, we investigated the expression patterns of Gpc4 in patients with epilepsy and in a pilocarpine-induced rat model of epilepsy. We also determined if altered Gpc4 expression resulted in increased susceptibility to seizures. Western blotting and immunofluorescent methods were utilized. Gpc4 was significantly increased in patients and epileptic rats induced by pilocarpine injection. According to behavioral studies, downregulation of Gpc4 by Gpc4 siRNA decreased spontaneous seizure frequency, while upregulation of Gpc4 by recombinant Gpc4 overexpression led to a converse result. These findings support the hypothesis that increased expression of Gpc4 in the brain is associated with epileptic seizures.
