abstractText | Aggregation of alpha-synuclein is a pathological hallmark of sporadic or familial PD. However, the detailed molecular mechanism responsible for the aggregation of alpha-synuclein has not been properly explored. In the present study, we have identified a novel role of an anti-tumorigenic BTB/POZ domain containing protein-2 (BPOZ-2) in the regulation of alpha-synuclein accumulation in dopaminergic (DA) neurons. MPP(+), an etiological factor for PD, significantly downregulated the expression of BPOZ-2 ahead of alpha-synuclein upregulation. Moreover, siRNA knockdown of BPOZ-2 alone stimulated the aggregation of alpha-synuclein protein; the effect was further induced in presence of MPP(+) in mouse primary DA neurons. Finally, the absence of BPOZ-2 in alpha-synuclein expressing neuronal populations of MPTP-intoxicated mouse and primate nigra indicates that the suppression of BPOZ-2 could be involved in the accumulation of alpha-synuclein protein. |
