Hybridization can lead to phenotypic differences arising from changes in gene expression patterns or new allele combinations. Variation in gene expression is thought to be controlled by differences in transcription regulation of parental alleles, either through cis- or trans-regulatory elements. A previous study among brook charr hybrids from different populations ...

1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) is a potent toxin used to selectively destroy dopaminergic neurons in the substantia nigra and induce parkinsonism. MPTP is metabolised to the 1-methyl-4-phenylpyridinium ion (MPP(+)) in glia, after which it enters the neuron via the dopamine transporter and results in elevated levels of oxidative stress. The mechanism through ...
