METHODS: Nerve growth factor-treated-rat adrenal pheochromocytoma cells of the line PC12 were co-incubated with 6-hydroxydopamine (6-OHDA), 1-methyl-4-phenylpyridinium ion (MPP (+)), and rotenone for 24 hours.

Oxidative stress induced by the neurotoxins MPTP, paraquat, maneb, and rotenone causes lipid peroxidation and protein misfolding that affects cell death through members of the Bcl-2 family.
Of the familial mutations identified thus far, two of the loci encode proteins associated with ubiquitin-proteasome degradation of misfolded proteins (Parkin and Uch-L1), and two encode proteins associated with mitochondria and oxidative stress (DJ-1 and PINK1).

Two of these genes are involved in the ubiquitin mediated pathway of protein degradation and the third one is a highly expressed protein in the synaptic terminal and is called alpha-synuclein.
In animal models, it has been shown that use of the household pesticide which is known to contain rotenone, causes PD.

Prolyl hydroxylation of hypoxible-inducible factor alpha (HIF-alpha) proteins is essential for their recognition by pVHL containing ubiquitin ligase complexes and subsequent degradation in oxygen (O (2))-replete cells.
Furthermore, cells treated with mitochondrial inhibitors, such as rotenone and myxothiazol, provided direct evidence that PHDs remain active in hypoxic cells lacking functional mitochondria.

In this cell line, neuronally differentiated by nerve growth factor, Parkin overproduction protected against cell death mediated by ceramide, but not by a variety of other cell death inducers (H (2) O (2), 4-hydroxynonenal, rotenone, 6-OHDA, tunicamycin, 2-mercaptoethanol and staurosporine).
Protection was abrogated by the proteasome inhibitor epoxomicin and disease-causing variants, indicating that it was mediated by the E3 ubiquitin ligase activity of Parkin.

Mutations in the ubiquitin ligase-encoding Parkin gene have been implicated in the pathogenesis of autosomal recessive Parkinson disease.
In comparing primary cultures of skeletal muscle derived from parkin knock-out and wild-type mice, we have found the absence of parkin to result in greater sensitivity to mitochondrial stressors rotenone and carbonyl cyanide 3-chlorophenylhydrazone, without any alteration in sensitivity to calcium ionophore or hydrogen peroxide.

We have recently shown that parkin (an E3 ubiquitin ligase) and PINK1 (a serine/threonine kinase) affect one other's stability, solubility, and tendency to form cytoprotective aggresomes (Um et al., 2009).
Consistent with our previous findings from parkin knockout mice, rat models of PD (6-hydroxydopamine-, rotenone-, or MG132-induced PD) were also associated with an increase in soluble and insoluble PINK1 levels as well as enhanced formation of parkin aggregates.

Among the five PD-linked genes identified so far, parkin, a protein-ubiquitin E3 ligase, appears to be the most prevalent genetic factor in PD.
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.

Naive and transfected cells were exposed to oxidative stress induced by rotenone, SIN-I, FeCl (2,) and to proteasomal inhibition by lactacystin.
Proteasomal inhibition caused a dose-dependent decrease in viability and induced protein aggregates formation containing alpha-synuclein and ubiquitin.

Treatment with rotenone, an inhibitor of complex I, resulted in an increase of detergent-resistant alpha-synuclein aggregates and a reduction in ATP level.

Increased ROS formation is known to induce protein degradation through the ubiquitin-proteasome pathway.
Formation of ROS was attenuated by rotenone, an inhibitor of the mitochondrial electron transport chain, nitro-l-arginine methyl ester, an inhibitor of nitric oxide synthase, and SB 203580, a specific inhibitor of p38 mitogen-activated protein kinase (p38 MAPK), which also attenuated total protein degradation.

In addition to inhibiting the mitochondrial respiratory chain, toxins known to cause Parkinson's disease (PD), such as 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine and rotenone, also strongly depolymerize microtubules and increase tubulin degradation.
Here we report that parkin, a protein-ubiquitin E3 ligase linked to PD, was tightly bound to microtubules in taxol-mediated microtubule coassembly assays.

Furthermore, proteasome inhibitor MG132 prevented the down-regulation of survivin expression and STAT3 dephosphorylation by deguelin, suggesting that the action mechanism of deguelin involves the degradation of survivin and phosphorylated STAT3 through the ubiquitin/proteasome pathway.

Depolymerization of microtubules by PD toxins such as rotenone disrupts vesicular transport.
On the other hand, parkin, one of the most frequently mutated genes in PD, encodes for a protein-ubiquitin E3 ligase that strongly binds to microtubules.

Epidemiological studies have suggested a correlation of pesticides and Parkinson's disease (PD) while genetic and biochemical studies have implicated the ubiquitin-proteasome system (UPS) in the pathogenesis of PD.
Six out of 25 representative pesticides, including rotenone, ziram, diethyldithiocarbamate, endosulfan, benomyl, and dieldrin, showed inhibitory effects on proteasome activities at low concentrations (10 nM to 10 microM).

The basis of neuronal vulnerability, degeneration, and sparing in PD are unknown, but there is increasing evidence to suggest that the ubiquitin-proteasome system (UPS) plays an important role in the pathogenesis of the disorder.

Nevertheless, Parkin-deficient mice could be more sensitive to other neurotoxins, such as rotenone or MPTP, which have different mechanisms of action; therefore, identifying conditions that precipitate parkinsonism specifically in Parkin-deficient mice would increase the utility of this model and could provide insight into the mechanism of AR-JP.
