J Neurochem. 2009;108:601-10 pubmed publisher..Taken together, we concluded that auto-oxidation of endogenous DA aggravates non-apoptotic cell death induced by over-expression of human mutant A53T alpha-syn in PC12 cells. ..
- Herrera F, Outeiro T. ?-Synuclein modifies huntingtin aggregation in living cells. FEBS Lett. 2012;586:7-12 pubmed publisher..Our results support the idea that co-aggregation of aggregation-prone proteins can contribute to the histopathology of neurodegenerative disorders...
- Golovko M, Faergeman N, Cole N, Castagnet P, Nussbaum R, Murphy E. Alpha-synuclein gene deletion decreases brain palmitate uptake and alters the palmitate metabolism in the absence of alpha-synuclein palmitate binding. Biochemistry. 2005;44:8251-9 pubmed..Thus, alpha-synuclein has effects on 16:0 uptake and metabolism similar to those of an FABP, but unlike FABP, it does not directly bind 16:0; hence, the mechanism underlying these effects is different from that of a classical FABP. ..
- Wakabayashi K, Hayashi S, Yoshimoto M, Kudo H, Takahashi H. NACP/alpha-synuclein-positive filamentous inclusions in astrocytes and oligodendrocytes of Parkinson's disease brains. Acta Neuropathol. 2000;99:14-20 pubmed..The number of inclusions was correlated with the severity of nigral neuronal loss. These findings indicate that abnormal accumulation of NACP/alpha-synuclein in glial cells is a pathological feature of PD related to its progression. ..
