Hypoxia inducible factor-1α expression is associated with hippocampal apoptosis during epileptogenesis.

Abstract Cell apoptosis can cause hippocampal neuronal loss after epileptic seizures. Hypoxia inducible factor (HIF)-1α is an important factor mediating apoptosis after brain injuries, such as cerebral ischemia and traumatic brain injures, but little research has been done on its role in the lithium chloride–pilocarpine induced epileptic model. Here, we used a rat model of pilocarpine-induced status epilepticus (SE) to investigate HIF-1α expression and apoptosis in the hippocampus, and to explore their relationship during epileptogenesis. 120 male Sprague Dawley (SD) rats were treated with lithium chloride–pilocarpine injections and divided into an experimental group (administered by MK-801) and a positive control group (administered by saline). Then the HIF-1α expression and hippocampal apoptosis were investigated by histological confirmation and western blotting at 24 h, 3 d, 7 d and 14 d, respectively. The results showed that the administration of MK-801 significantly reduced ( P P P
