Alterations of apoptosis and autophagy in developing brain of rats with epilepsy: Changes in LC3, P62, Beclin-1 and Bcl-2 levels
چکیده انگلیسی
Current studies have indicated that apoptotic and autophagic signaling pathways are triggered by epileptic seizures, but the precise roles of these processes in epilepsy-induced neuronal loss remain unclear. Identifying a concrete molecular mechanism may help researchers develop relevant epilepsy therapies that are more effective than existing treatments. Autophagy is a type of conserved degradation that contributes to cellular homeostasis. The involved signaling pathways allow us to observe alterations in autophagy and apoptosis during epileptic seizures over time. This study investigated the time-dependent changes in autophagy, apoptosis and neuronal morphology in developing brain of epilepsy model rats. At 48 h after epileptic seizure onset, the number of neurons in neocortex decreased, and the number of apoptotic cells in neocortex increased. The ratio of microtubule-associated protein 1 light chain 3 (LC3) II to LC3 I and Beclin-1 protein levels increased from 12 h to 48 h after epileptic seizure onset. P62 protein and Bcl-2 protein levels decreased from 24 h to 48 h after epileptic seizure onset. The changes in the levels of these autophagy and apoptosis markers indicate that autophagy starts before apoptosis in rats with epilepsy, demonstrating a potential role of autophagy in epilepsy-induced neuronal loss in developing brain.
