Distribution of α-synuclein truncations in cells / 中国药理学通报

ABSTRACT

Aim To study of the expression and distribution of four α-synuclein truncations in three cells.Method Four α-synuclein gene truncations were obtained by PCR method,followed by subcloning into the pEGFP-N1 eukaryotic expression vector.Four obtained recombination plasmids were transfected into MN9D cells,PC12 cells and SH-SY5Y cells using Lipofectamine 2000 respectively.The expression and distribution of four α-synuclein truncations were observed by Confocal.Results Distribution of four α-synuclein truncations was discrepant obviously,the truncations,with more C terminal remained,were prone to emerging in nuclei.Conclusion Localization of α-synuclein protein in cells may be related to the C terminal,and the whole C terminal plays an important role in distribution of α-synuclein into nuclei.
