Poly(ADP-ribose) polymerase activation mediates 1-methyl-4-phenyl-1, 2,3,6-tetrahydropyridine (MPTP)-induced parkinsonism.

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a neurotoxin that causes parkinsonism in humans and nonhuman animals, and its use has led to greater understanding of the pathogenesis of Parkinson's disease. However, its molecular targets have not been defined. We show that mice lacking the gene for poly(ADP-ribose) polymerase (PARP), which catalyzes the attachment of ADP ribose units fro...

The clinical syndrome of striatal dopamine deficiency. Parkinsonism induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP).

Exposure to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) produces a syndrome that resembles Parkinson's disease. To compare the biochemical abnormalities produced by this compound in human beings with those occurring in Parkinson's disease, we examined biogenic amine metabolites in cerebrospinal fluid and urine from six patients with MPTP-induced parkinsonism and eight patients with Park...

Neuropharmacological approach against MPTP (1-methyl-4-phenyl-1,2,3,6- tetrahydropyridine)-induced mouse model of Parkinson's disease.

Parkinson's disease (PD) is a common neurodegenerative disease that appears essentially as a sporadic condition. PD is well known to be a chronic and progressive neurodegenerative disease produced by a selective degeneration of dopaminergic neurons in the substantia nigra pars compacta. The main clinical features of PD include tremor, bradykinesia, rigidity and postural instability. Most insigh...

SIRT2 enhances 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced nigrostriatal damage via apoptotic pathway

Sirtuins are NAD-dependent protein deacetylases that were shown to have protective effects against different age-related diseases. SIRT2 is a strong deacetylase that is highly expressed in brain. It has been associated with neurodegenerative diseases. MPTP (1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine) is a dopaminergic neurotoxin that displays clinical features of Parkinson's Disease (PD). MPT...

Adaptive acetylcholinesterase splicing patterns attenuate 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine-induced Parkinsonism in mice.

Balanced dopaminergic cholinergic interactions are crucial for proper basal ganglia function. This is dramatically demonstrated by the worsening of Parkinson's disease symptoms following acetylcholinesterase (AChE) inhibition. Typically, in the brain, the synapse-anchored synaptic AChE (AChE-S) variant is prevalent whereas the soluble readthrough AChE (AChE-R) variant is induced in response to ...
