ABSTRACT
Objective To investigate the effects of subthalamic nucleus (STN)-deep brain stimulation (DBS) on expression of dopamine and adenosine 3'5'-monophosphate-regulated phosphor-protein(DARPP-32) and its phosphorylated proteins in corpus striatum of rat models with levodopa-induced dyskinesia. Methods The rat models of levodopa-induced dyskinesia were set up and were given STN-DBS (stimulation group). The expression of DARPP-32 and its phosphorylated proteins in corpus striatum (damage side and normal side) were detected and compared with sham-stimulation group and sham-operation group. Results There was no significant difference in the expression of DARPP-32 total protein in corpus striatum of rats with dyskinesia among three groups (P>0.05). The expression of Phosphor-Thr34-DARPP-32 protein in the damage side of corpus striatum in stimulation group was significantly lower than that in sham-stimulation group and sham-operation group (P<0.05), while the expression of Phosphor-Thr75-DARPP-32 protein in the damage side of corpus striatum in stimulation group was significantly higher than that in sham-stimulation group and sham-operation group (P<0.05). Conclusion DARPP-32 and its phosphorylated proteins play an important role in the pathogenesis of levodopa-induced dyskinesia.
