摘要


We investigated that microRNA (miRNA)-141 protects against epilepsy-induced apoptosis and its reaction mechanism. The serum expression of miRNA-141 in epilepsy model mice and control volunteer was measured by quantitative reverse-transcription polymerase chain reaction. We found that miRNA-141 serum expression was upregulated in patients with epilepsy. Overexpression of miRNA-141 induced nerve cell apoptosis, suppressed proliferation, promoted caspase-3/9, Bax and p53 protein expression, and reduced silent information regulator 1 (SIRT1) protein expression in vitro model. In addition, the downexpression miRNA-141 using si-miRNA-141 reduced nerve cell apoptosis and increased proliferation, suppressed caspase-3/9, Bax and p53 protein expression, induced SIRT1 protein expression. SIRT1 inhibitor (nicotinamide) decreased SIRT1, reduced the effects of miRNA-141 on nerve cell apoptosis in vitro model of epilepsy through SIRT1/p53. SIRT1 agonist also reduced the effects of miRNA-141 overexpression on nerve cell apoptosis in vitro model of epilepsy through SIRT1/p53. Our preliminary findings indicate that anti-miRNA-141 protects against epilepsy-induced apoptosis via SIRT1/p53 expression.
