In the present study, we examined the possible functional relationship between alpha-synuclein and several forms of matrix metalloproteinases (MMPs) in the human dopaminergic neuroblastoma (SK-N-BE) cell line. When SK-N-BE cells were transiently transfected with alpha-synuclein, it was secreted into the extracellular culture media, concomitantly with a significant decrease in cell viability. Also the addition of nitric oxide-generating compounds to the cells caused the secreted alpha-synuclein to be digested, producing a small fragment whose size was similar to that of the fragment generated during the incubation of alpha-synuclein with various MMPs in vitro. Among several forms of MMPs, alpha-synuclein was cleaved most efficiently by MMP-3, and MALDI-TOF mass spectra analysis showed that alpha-synuclein is cleaved from its C-terminal end with at least four cleavage sites within the non-Abeta component of AD amyloid sequence. Compared with the intact form, the protein aggregation of alpha-synuclein was remarkably facilitated in the presence of the proteolytic fragments, and the fragment-induced aggregates showed more toxic effect on cell viability. Moreover, the levels of MMP-3 were also found to be increased significantly in the rat PD brain model produced by the cerebral injection of 6-hydroxydopamine into the substantia nigra. The present study suggests that the extracellularly secreted alpha-synuclein could be processed via the activation of MMP-3 in a selective manner."xsd:string |
