These results suggest that iptakalim may open mitochondrial K (ATP) channels to modulate dopamine transporter and reduce extracellular dopamine levels, thereby it protecting PC12 cells against rotenone-induced injury.

These results are consistent with prior reports suggesting that the selective vulnerability of the substantia nigra to MPTP involves both uptake by the dopamine transporter as well as complex I inhibition, and they show that rotenone produces a unique pattern of central nervous system damage.

The MPP+-induced I (GABA) run-down can be prevented by a DA transporter inhibitor, mazindol, and can be mimicked by a metabolic inhibitor, rotenone.

Tyrosine hydroxylase (TH) and vesicular monoamine transporter 2 (VMAT (2)) were markedly down-regulated, and dopamine transporter (DAT) was up-regulated in the cells.

We demonstrate that expression of all alpha-synuclein isoforms enhances toxicity of general complex I inhibition (rotenone), but only the expression of mutant alpha-synucleins induces significant increased DAT-dependent toxicity of very low concentrations of MPP+ compared to wild-type protein.

The purpose of this study was to determine whether mitochondrial inhibition alters dopamine transporter (DAT) function.
Although all of the toxins inhibited [(3) H] DA uptake, there was a large variation in their inhibitory potencies, the rank order being rotenone>> cyanide> azide> 3-NP>> malonate.

In contrast, when primary cultures of dopaminergic neurons were exposed to AMPH in the presence of subtoxic doses of the mitochondrial complex I inhibitor rotenone, cell death was dramatically increased, mimicking the effects of a known parkinsonism-inducing toxin.
As in earlier studies, AMPH rapidly redistributed vesicular DA to the cytoplasm, where it underwent outward transport through the DA transporter.

Inhibiting DA uptake through dopamine transporter or treating the cell with antioxidants significantly reduced oxidative stress and dopamine toxicity.
Here, we show that overexpression of parkin protected human DA neuroblastoma cell line (SH-SY5Y) against apoptosis induced by DA or 6-OHDA, but not by H (2) O (2) or rotenone.

A human neuroblastoma cell line expressing the dopamine transporter (DAT) was utilized to examine the effects of MPP+ on acute physiologic responses and subsequent cell death.
The lipophilic complex I inhibitor, rotenone, increased proton excretion in both cell lines.

Although a mean lethal dose of MPP (+) led to ROS production in identified dopaminergic neurons, toxic doses of the Complex I inhibitor rotenone did not.
Concurrent with ROS formation, MPP (+) redistributed vesicular DA to the cytoplasm prior to its extrusion from the cell by reverse transport via the DA transporter.

The first group comprehends 6-OHDA e MPTP and recently rotenone, paraquat and epoxomicin treated animals that shows some of human disease characteristics.
Recently has emerged the important role of neuroimaging (Dopamine Transporter SPECT, 18FDopa-PET) as surrogate biomarker of PD progression.

We show that alpha-synuclein knockdown has no effect on cellular survival either under normal growth conditions over 5 days or in the presence of the mitochondrial inhibitor rotenone.
Knockdown does, however, confer resistance to the dopamine transporter (DAT)-dependent neurotoxin N-methyl-4-phenylpyridinium (MPP (+)).

MPTP is metabolized in the brain to MPP (+), which is taken up into dopaminergic neurons via the dopamine transporter and assumed to impair mitochondrial function.
For comparison, the respiratory toxins FCCP, a cyanide analog that uncouples mitochondrial ATP production, and rotenone, a NADH dehydrogenase inhibitor, were also tested.

After this initial finding, we found that IFN-gamma-deficient mice displayed attenuated 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced substantia nigra pars compacta dopaminergic cell loss along with reduced loss of striatal tyrosine hydroxylase and dopamine transporter fiber density.
To examine more mechanistically the role of IFN-gamma in microglial activation, we evaluated the interactions between microglia and dopaminergic neurons in an in vitro mixed microglia/midbrain neuron rotenone-induced death paradigm.
