ABSTRACT
Objective To investigate the expression of cyclin dependent kinases 5(CDK5)in the temporal lobes of the epilepsy patients and to explore the possible roles of CDK5 in the pathogenesis of refractory epilepsy.Methods The brain tissues of intractable epilepsy(IE)were studied by fluorescence quantative polymerase chain reaction(FQ-PCR)for CDK5 mRNA,while immunohistochemistry and Western blot were used to study the protein expression.Nonepileptogenic control brain tissues were used for comparison.Results FQ-PCR analysis showed that the expression of CDK5 mRNA in epilepsy patients was significant higher than those in the control group.And immunohistochemistry showed that the protein mainly existed in the neuron and glial.At the 35000 relative molecular mass,Western blot could been seen that there is a limpid strap.The optical density of CDK5 in IE(temporal lobe 1.4293?0.1839,hippocampus 2.0733?0.4738)was significantly higher than that in the control(temporal lobe 0.9680?0.4147, hippocampus 1.4030?0.6160,P
