Identification of differentially expressed proteins in striatum of maneb-and paraquat-induced Parkinson's disease phenotype in mouse.Neurotoxicol Teratol. 2007 Sep-Oct; 29(5):578-85.NT
Behavioral, phenotypic and biochemical changes induced by maneb+paraquat (MB+PQ) in experimental animals have shown their role in the etiologies of Parkinson's disease (PD); however, MB+PQ induced neuronal damage at genome and proteome level have not yet been clearly understood. The present study was undertaken to investigate the differential protein expression patterns in control and MB+PQ treated mouse striatum and to identify differentially expressed proteins. Animals were treated with and without MB+PQ, twice a week for three, six and nine weeks and proteome profiles of striatum were compared. Three differentially expressed proteins were identified as complexin-I, alpha-enolase and glia maturation factor-beta (GMF-beta) using 2D-PAGE and mass spectrometry. The differential expressions were also confirmed at transcription level by semi-quantitative RT-PCR. The results suggest the involvement of complexin-I, alpha-enolase and GMF-beta in MB+PQ induced PD phenotype in mouse.
