echinoderm microtubule-associated protein -like protein 5 in anterior temporal neocortex of patients with intractable epilepsy

objective(s):emap-like protein 5 (eml5) is a new echinoderm microtubule-associated protein that is expressed in the central nervous system. the aim of this study was to investigate the expression profile of eml5 in the anterior temporal neocortex of patients presenting with intractable epilepsy (ie). materials and methods:western blot assays were performed to determine eml5 expression in 36 surgically resected anterior temporal neocortices of patients with ie and eight control tissues. immunohistochemistry and immunofluorescence were employed to explore protein expression in ie. results:eml5 was highly expressed in both neurons and glial cells of the anterior temporal neocortex of ie patients, whereas only low levels of eml5 were detected in control brain tissues. western blotting showed an enhanced expression of eml5 protein in the anterior temporal neocortex of ie (optical density (od) = 1.8030 ± 0.1335/1.1852 ± 0.2253,p<0.05) compared with normal control tissues. conclusion:the results demonstrate that highly expressed eml5 in the neurons and glial cells of the cortex of patients with epilepsy is associated with microtubular dysfunction after frequent and recurrent seizures.
