δ-Aminolevulinate Dehydratase Activity is Stimulated in a MPTP Mouse Model of Parkinson's Disease: Correlation with Myeloperoxidase Activity.

ABSTRACT: Myeloperoxidase (MPO) is an inducible heme peroxidase responsive to some stress situations. It is already known that its activity is stimulated in neurodegenerative disorders and in the animal model of parkinson's disease (PD) induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP). By contrast, the role of δ-aminolevulinate dehydratase (δ-ALA-D), an essential enzyme for heme synthesis, has not been investigated in the MPTP model. The aim of this study was to investigate the involvement of striatal δ-ALA-D activity in an acute model of PD, induced by MPTP, in C57Bl/6 mice and its correlation with MPO activity. Animals received four MPTP injections (20 mg/kg, i.p.) or saline (vehicle) to induce a PD model. 7 days after MPTP administration, the motor function was evaluated through rot
