Expression of HSP27 in CA1 area of hippocampus in temporal lobe epilepsy model

To explore the expression of heat shock protein 27 (HSP27) in the CA1 area of hippocampus in temporal lobe epilepsy (TLE) so as to elucidate the relationship between HSP27 and epileptogenesis of TLE. The model of TLE was induced by lithium-pilocarpine in the experiment group. And the rats were further divided into the STLE and non-STLE groups based upon the absence or presence of recurrent spontaneous seizure in the next 30 days. Total protein fractions from CA1 area of hippocampus were successively obtained through tissue homogenates abstraction. The HSP27 expression in the CA1 area of hippocamp from three groups was semi-quantitatively analyzed by Western blot. And the expression of HSP27 in CA1 area was detected by pre-embedding immunogold electron microscopy. Expression of HSP27 in the hippocampus CA1 area as detected by Western blot was in accord with that by immunogold electron microscopy. Relative optical density values were 0.912 ± 0.011, 0.431 ± 0.011 and 0.428 ± 0.010 respectively. And gold particle
