PHARMACEUTICAL COMPOSITION FOR PARKINSON'S DISEASE CONTAINING PEA-15 FUSION PROTEIN
摘要
Phosphoprotein enriched in astrocytes-15 (PEA-15) is a small protein created in neurons or astrocytic cells in brain. This protein which is a multi-functional protein can increase the cell survival rate thanks to its antiapoptotic and proapoptotic properties. Parkinson's disease is a neurodegenerative disease that dopamine neurons are reduced in substantia nigra in brain. The inventers found out that PEP-1-PEA-15 fusion protein can protect dopamine neurons from oxidation stress in SH-SY5Y neuroblastom cells and animals suffering from Parkinson's disease. It is confirmed that PEP-1-PEA-15 fusion protein can be transferred to SH-SY5Y cells and substantia nigra through western blot analysis. PEP-1-PEA-15 fusion protein prevents the active oxygen species production DNA tessellation induced to MPP+ and induces SH-SY5Y cell survival. Transmitted PEP-1-PEA-15 fusion protein improves the expression level of Bcl-2 protein but reduces the impression level of Bax protein. Also, PEP-1-PEA-15 fusion protein is transmitted to substantia nigra and prevents dopamine neuron cell death in substantia nigra. Therefore, PEP-1-PEA-15 fusion protein can prevent and treat Parkinson's disease.
