Abstract
Dopamine (DA), a critical neurotransmitter of both the central and peripheral nerve system, plays important roles in a series of biological processes. Dysfunction of dopaminergic signalling may lead to a series of developmental disorders, including attention deficit/hyperactivity disorder, autism and schizophrenia. However, the exact roles of dopaminergic signalling in these diseases are far from fully understood. We analyse the roles of dopaminergic signalling in multiple physiological and pathological processes, focusing on brain development and related disorders. By summarizing current research in this area, we provide guidance for future studies. This review seeks to deepen our understanding of dopaminergic signalling in developmental disorders, which may offer clues for developing more effective therapeutic drugs.

Abstract
A simple and sensitive dopamine (DA) electrochemical sensor was fabricated based on magnetism-assisted modification of screen printed electrode (SPE) with magnetic multi-walled carbon nanotubes (mMWCNTs). The mMWCNTs modified electrodes (mMWCNTs/SPE) combines the advantages of SPE and the simultaneous contribution of magnetic nanoparticles (MNPs) and MWCNTs, increasing sensitivity and selectivity of DA detection. The linearity was found between 5μM to 180μM, with the limit of detection (LOD) of 0.43μM. In the mean time, this modified electrode exhibited excellent selectivity for DA detection with almost no interference from ascorbic acid (AA), which co-exists with DA in many bio-samples and causes common interference. Finally, this novel electrode has been applied to determine DA concentration in spiked human blood serum and satisfactory recovery was found in the range of 97.43-102.94% with the RSDs of less than 2.27%. This work developed a sensitive and reliable electrochemical analytical method based on mMWCNTs/SPE, which exhibits great potential for diagnosis of the diseases related to DA.

[PMID: 20040103 PMCID: PMC2808306 DOI: 10.1186/1471-2350-10-147] [Citation(s) in RCA: 14] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/18/2009] [Accepted: 12/29/2009] [Indexed: 02/02/2023]
Abstract
Background The tumour supressor gene TP53 is thought to be involved in neural apoptosis. The polymorphism at codon 72 in TP53 and the long form variants of the upstream variable number of tandem repeats (uVNTR) polymorphism in the dopamine D4 receptor (DRD4) gene are reported to confer susceptibility to schizophrenia. Methods We recruited 934 patients with schizophrenia and 433 healthy individuals, and genotyped the locus of the TP53 codon 72 and DRD4 uVNTR polymorphisms by combining the polymerase chain reaction-restriction fragment length polymorphism method (PCR-RFLP) with direct sequencing. Results No significant differences were found in the frequency of the genotype of the TP53 codon72 polymorphism between patients with schizophrenia and their controls. However, the long form alleles (≥ 5 repeats) of the DRD4 uVNTR polymorphism were more frequent in patients with schizophrenia than in controls (p = 0.001). Hence, this class of alleles might be a risk factor for enhanced vulnerability to schizophrenia (odds ratio = 3.189, 95% confidence interval = 1.535-6.622). In the logistic regression analysis, the long form variants of the DRD4 polymorphism did predict schizophrenia after the contributions of the age and gender of the subjects were included (p = 0.036, OR = 2.319), but the CC and GG genotypes of the codon 72 polymorphism of TP53 did not. Conclusions The long form variants of the uVNTR polymorphism in DRD4 were associated with schizophrenia, in a manner that was independent of the TP53 codon 72 polymorphism. In addition, given that the genetic effect of the TP53 codon 72 polymorphism on the risk of developing schizophrenia was very small, this polymorphism is unlikely to be associated with schizophrenia. The roles that other single nucleotide polymorphisms (SNPs) in the TP53 gene or in other apoptosis-related genes play in the synaptic dysfunction involved in the pathogenesis of schizophrenia should be investigated.

Abstract
BACKGROUND The dopaminergic pathway may be of interest in assessing risk of non-small cell lung cancer (NSCLC). Dopamine receptors are expressed in alveolar epithelial cells and human lung tumours, and dopamine inhibits both cell proliferation in vitro and growth of lung tumour xenografts in nude mice. Moreover, dopamine selectively inhibits the vascular permeability and angiogenic activity of vascular endothelial growth factor (VPF/VEGF). The bioavailability of dopamine is regulated by dopamine receptors D2 (DRD2), D4 (DRD4) and dopamine transporter 1 (DAT1/SLC6A3) genes. METHODS We have analysed 10 single nucleotide polymorphisms in DRD2, DRD4 and DAT1/SLC6A3 genes in relation to lung cancer risk in a case-control study of smoking subjects. The study subjects were 413 healthy individuals from general population and 335 NSCLC cases. Both cases and controls were Caucasians of Norwegian origin. RESULTS We demonstrate that DRD2 polymorphisms -141Cdel, 3208G>T, TaqIB; DRD4 -521C>T and DAT1/SLC6A3 -1476T>G are associated with a two- to five-fold increased NSCLC risk. The variant alleles of DRD2 1412A>G and 960C>G had protective effects. CONCLUSION The dopamine receptor/transport gene polymorphisms are associated with the risk of NSCLC among smokers. The data show that the polymorphisms resulting in lower dopamine bioavailability were associated with increased risk of NSCLC.

Abstract
The human p53 tumor suppressor gene (TP53) is considered as a candidate susceptibility gene for schizophrenia because of its functions in neurodevelopment. To test for an association between TP53 and schizophrenia, both the case-control study and the transmission disequilibrium test (TDT) were performed on genotype data from eight polymorphisms in TP53. Our samples included 286 Toronto schizophrenia cases and 264 controls, and 163 Portuguese nuclear families. In the Toronto case-control study significant differences of allele frequencies of the CAA Ins/Del (p=0.027) and the 16bp Ins/Del (p=0.022) were detected. In TDT analysis we found significant differences for transmission of the CAA Ins/Del (p=0.017) in Portuguese schizophrenia families. Haplotype analysis also showed a significant association between TP53 and schizophrenia. These results provide further evidence that TP53 may play a role in the pathogenesis of schizophrenia.

Abstract
Cocaine abuse is a significant problem in the United States, including its use by approximately 1% of pregnant women. Cocaine acts as an indirect agonist of dopamine at the dopamine transporter, resulting in the presence of excess dopamine in the synapse. Since synaptic dopamine can rapidly oxidize to form free radicals, it was hypothesized that exposure to this drug might produce damage in dopaminergic systems such as the substantia nigra pars compacta, damage to which is a hallmark of Parkinson's disease. To test this hypothesis we exposed mice both in utero and as adults to cocaine and examined its effects on the nigrostriatal system. We found that exposure to cocaine both in utero or as adults did not affect substantia nigra cell number, but did make these neurons more susceptible to the parkinsonian toxin 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine. We also found long-lasting changes in D2 receptor mRNA levels as well as changes in the monoamine transport system and several growth factors. This work suggests that use of cocaine might be a predisposing factor for development of Parkinson's disease in both adults exposed chronically as well as in individuals exposed prenatally.

Abstract
It has been reported that male mice are more susceptible to the neurotoxic effects of methamphetamine (MA) upon the nigrostriatal dopaminergic (NSDA) system. Since MA utilizes the dopamine transporter (DAT) to exert its effects, in the present study, we tested for differences in the dynamics of DAT function between male and female mice as an approach to understand some of the bases for this sex difference in MA-induced NSDA neurotoxicity. To accomplish this goal, in Experiment 1, the amount of dopamine (DA) obtained following DA infusion into the superfused striatal tissue fragments of male and female mice was measured while in Experiment 2 responses to the DA uptake blocker, nomifensine (NMF), were assessed in these preparations. The differences obtained to these treatments demonstrate that marked differences in DA transporter activity exist between male and female mice. When combining the DA and DOPAC measures from these two experiments, the data suggest that the female mice show a more active and efficient recovery and vesicular packaging of extracellular DA. These findings have important implications for sex differences in NSDA functions and responses to neurotoxins which enter the neurons via the DAT.

Abstract
Free cytoplasmic dopamine may be involved in the genesis of neuronal degeneration in Parkinson's disease and other such diseases. We used SH-SY5Y human neuroblastoma cells to study the effect of dopamine on cell death, activation of stress-induced pathways, and expression of alpha-synuclein, the characteristic protein accumulated in Lewy bodies. We show that 100 and 500 microM dopamine causes a 40% and 60% decrease of viability, respectively, and triggers autophagy after 24 hr of exposure, characterized by the presence of numerous cytoplasmic vacuoles with inclusions. Dopamine causes mitochondrial aggregation in adherent cells prior to the loss of functionality. Plasma membrane and nucleus also maintain their integrity. Cell viability is protected by the dopamine transporter blocker nomifensine and the antioxidants N-acetylcysteine and ascorbic acid. Dopamine activates the stress-response kinases, SAPK/JNK and p38, but not ERK/MAPK or MEK, and increases alpha-synuclein expression. Both cell viability and the increase in alpha-synuclein expression are prevented by antioxidants; by the specific inhibitors of p38 and SAPK/JNK, SB203580 and SP600125, respectively; and by the inhibitor of autophagy 3-methyladenine. This indicates that oxidative stress, stress-activated kinases, and factors involved in autophagy up-regulate alpha-synuclein content. The results show that nonapoptotic death pathways are triggered by dopamine, leading to autophagy. These findings should be taken into account in the search for strategies to protect dopaminergic neurons from degeneration.

Abstract
A variety of mechanisms have been proposed as explanations for the distinctive neuropathology of Parkinson's disease, such as increased iron levels, increased oxidant stress or decreased antioxidant defences. The vulnerability of dopamine-containing neurons towards cell death has attracted much attention to the dopamine molecule itself as one of the probable neurotoxic factors leading to neurodegeneration. The similarity between apomorphine and dopamine with regards to their chemical, pharmacological and toxicological properties provided a basis for investigating the nature of the toxicity of the former agent. In this study the CHO-K1 cell line was exposed to different concentrations of apomorphine, and markers of cell death and apoptosis were studied. Apomorphine reduced cell proliferation in a dose-dependent fashion after 72 h incubation. Furthermore, apomorphine induced dose-dependent cell death at concentrations of 10-50 microM. The CHO-K1 line showed specific markers of apoptosis such as the typical DNA laddering phenomenon on agarose gel, morphological changes of apoptotic nuclei as described by in situ end labelling, and annexin binding. These data strongly suggest that apomorphine, like dopamine, elicits its cytotoxic effect with an apoptotic mechanism.

Abstract
Neuronal NMB cells were used to determine changes in gene expression upon treatment with dopamine. Twelve differentially expressed cDNAs were identified and cloned, one of them having 99.4% sequence homology with isoform 2 of a voltage-dependent anion channel (VDAC-2). The known role of VDAC, a mitochondrial outer-membrane protein, in transport of anions, pore formation, and release of cytochrome C prompted us to investigate the possible role of VDAC gene family in dopamine-induced apoptosis. Semi-quantitative PCR analysis indicated that expression of the three VDAC isoforms was reduced by dopamine. Immunoblotting with anti-VDAC antibodies detected two VDAC protein bands of 33 and 34 kDa. Dopamine decreased differentially the immunoreactivity of the 34 kDa protein. Whether the decrease in VDAC expression influence the mitochondrial membrane potential (Delta(Psi)(m)) was determined with the dye Rhodamine-123. Dopamine indeed decreased the mitochondrial Delta(Psi)(m), but the maximum effect was observed within 3 h, prior to the decrease in VDAC mRNA or protein levels. Cyclosporin A, a blocker of the mitochondrial pore complex, prevented the decrease in Delta(Psi)(m), but did not rescue the cells from dopamine toxicity. To elucidate possible involvement of protease caspases in dopamine-induced apoptosis, the effect of the caspase inhibitor z-Val-Ala-Asp(Ome)-FMK (zVAD) was determined. zVAD decreased dopamine toxicity, yet it did not rescue the mitochondrial Delta(Psi)(m) drop. Dopamine also decreased ATP levels. Finally, transfection of NMB cells with pcDNA-VDAC decreased the cytotoxic effect of dopamine. These findings are in agreement with the notion that the mitochondria, and VDAC, are important participants in dopamine-induced apoptosis.
