Abstract

Objective: The mechanisms underlying the pathogenesis of intractable epilepsy (IE) are still unclear. This study aimed to investigate the role of phosphorylation of Cyclase Response Element Binding Protein (p-CREB)/microRNA-132 (miR-132) signal pathway in the epileptogenesis.

Methods: Temporal lobe epilepsy (TLE) was induced in rodents, and the brain tissues were collected. P-CREB expression was detected by Western blot assay and immunochemistry at 6 h, 24 h, 3 d, 7 d, 14 d, 30 d and 60 d after induced status epilepsy (SE), respectively, and in patients with TLE. The expression of miR-132 was detected by RT-PCR.

Results: The p-CREB and miR-132 were highly expressed in both rats and patients with TLE as compared to controls.

Conclusions: The expression of p-CREB and miR-132 increases in epilepsy rats and patients, suggesting a possible pathogenetic role of p-CREB and miR-132 in TLE via modulating the dendritic plasticity.
