Parkinson’s disease is representative neurodegenerative disorder in recent century. We investigated that the improvement effect of Korean propolis extracts on Parkinson’s disease and its protein signal tranduction in SH-SY5Y neuroblastoma cells. To apply MPTP in which caused Parkinson’s disease and propolis extracts, we evaluated the optimal concentration by cell viability assay. MPTP and propolis extracts concentration is 1 mM and 10 μg/mL for SH-SY5Y, respectively. 1 mM of MPTP were triggered aggregation of α-synuclein and apoptosis. However, simultaneously treatment of propolis extracts with MPTP was inhibited aggregation of α-synuclein and apoptosis signaling. By Western blotting analysis, propolis extracts decreased the ubiquitination, PARP and caspase-3 activation. And propolis extracts prevented the releasing of cytochrome C from mitochondria to cytosol fraction and Inhibited Bak fragmentation. Especially, although phosphorylation of ERK, SAPK/JNK and p38 was strongly increased by MPTP, propolis extracts was inhibition phophorylation of ERK and SAPK/JNK. In this study, we verified that the novel function of propolis extracts in Parkinson’s disesase improvement. Furthermore, we claified the signaling molecule change of Parkinson’s disease-related apoptosis by MPTP and propolis extracts. Therefore, we suggested that propolis extracts is a useful substance with functional components for improvement of neurodegenerative disease.
