    Background: Bipolar affective disorder (BAD) is a psychiatric illness characterized by episodes of mania and depression. Although the etiology is not clear, epidemiological studies suggest it is a result of an interaction of genetic and environmental factors. Despite of enormous efforts and abundant studies conducted, none has yet been identified definitively a gene susceptible to bipolar disorder.

    Methods: Ninety-four Bulgarian patients diagnosed with bipolar disorder and 184 Bulgarian healthy individuals, were used for genotyping of 191 single nucleotide polymorphisms (SNPs) by TaqMan and/or Invader assays. Seventeen SNPs that revealed P value less than 0.05 in the first screening were genotyped using an additional independent set of samples, consisting of 78 BAD cases and 372 controls.

    Results: After applying the Bonferonni correction on genotyping results of 172 cases and 556 controls, only one SNP, rs1800883, in the HTR5A gene revealed a significant level of P value (P=0.000097; odds ratio=1.80 (95%CI, 1.27-2.54); corrected P=0.017).

    Conclusions: Our findings suggest that HTR5A gene could play an important role in the pathogenesis of bipolar disorder in our population. However these findings should be viewed with caution and replication studies in other populations are necessary in support of these findings.

    With dense single-nucleotide polymorphism (SNP) maps for 199 drug-related genes, we examined associations between 4190 SNPs and 38 commonly measured quantitative traits using data from 752 healthy Japanese subjects. On analysis, we observed a strong association between five SNPs within the uridine diphosphate glucuronosyltransferase 1A1 (UGT1A1) gene and serum total bilirubin levels (minimum P-value in Mann-Whitney test=1.82 x 10(10)). UGT1A1 catalyzes the conjugation of bilirubin with glucuronic acid, thus enhancing bilirubin elimination. This enzyme is known to play an important role in the variation of serum bilirubin levels. The five SNPs, including a nonsynonymous SNP-rs4148323 (211G>A or G71R variant allele known as UGT1A1*6)-showed strong linkage disequilibrium with each other. No other genes were clearly associated with serum total bilirubin levels. Results of linear multiple regression analysis on serum total bilirubin levels followed by analysis of variance showed that at least 13% of the variance in serum total bilirubin levels could be explained by three haplotype-tagging SNPs in the UGT1A1 gene.

    Schizophrenia is a complex disease, likely to be caused by a combination of serial alterations in a number of genes and environmental factors. The dorsolateral prefrontal cortex (Brodmann's Area 46) is involved in schizophrenia and executes high-level functions such as working memory, differentiation of conflicting thoughts, determination of right and wrong concepts and attitudes, correct social behavior and personality expression. Global proteomic analysis of post-mortem dorsolateral prefrontal cortex samples from schizophrenia patients and non-schizophrenic individuals was performed using stable isotope labeling and shotgun proteomics. The analysis resulted in the identification of 1,261 proteins, 84 of which showed statistically significant differential expression, reinforcing previous data supporting the involvement of the immune system, calcium homeostasis, cytoskeleton assembly, and energy metabolism in schizophrenia. In addition a number of new potential markers were found that may contribute to the understanding of the pathogenesis of this complex disease.

    Global proteomic analysis of post-mortem anterior temporal lobe samples from schizophrenia patients and non-schizophrenia individuals was performed using stable isotope labeling and shotgun proteomics. Our analysis resulted in the identification of 479 proteins, 37 of which showed statistically significant differential expression. Pathways affected by differential protein expression include transport, signal transduction, energy pathways, cell growth and maintenance and protein metabolism. The collection of protein alterations identified here reinforces the importance of myelin/oligodendrocyte and calcium homeostasis in schizophrenia, and reveals a number of new potential markers that may contribute to the understanding of the pathogenesis of this complex disease.

    Bipolar disorder is known to be subject to maternal transmission. Mitochondrial DNA has been suggested as playing a role in the illness. NDUFV2, located on 18p11.31-p11.2, encodes an important subunit of mitochondrial NADH (complex I). Previous studies have reported the association of NDUFV2 with bipolar disorder in the Japanese and Caucasian populations. Whether it is also a susceptible gene in the Chinese population is unknown. To study the role of NDUFV2 in bipolar disorder in the Chinese population, 506 unrelated bipolar patients and 507 unrelated controls of Chinese Han origin were recruited. Six SNPs (rs11661859, rs6506640, rs1156044, rs4148965, rs906807, rs977581) were genotyped using either TaqMan technology or direct sequencing. The haplotype consisting of rs6506640 (-342G > A) and rs906807 (86C > T) was found to be associated with bipolar disorder (global p = 0.012 before corrected, p = 0.030 after 10,000 permutations; individual p (A-T of rs6506640-rs906807) = 0.014 after 100,000 permutations (p = 0.0065 before corrected). The genotype frequency of rs906807 differed between bipolar female patients and female controls (p = 0.012, uncorrected). No other individual associations of SNPs with bipolar were detected. Our study indicated that the regions spanning from the promoter to the exon 2 may contain susceptible polymorphisms which predispose to bipolar disorder.

    Several studies have suggested mitochondrial abnormality in bipolar disorder (BD) and schizophrenia (SZ). We have previously reported the decreased expression of mitochondrial complex I subunit gene, NDUFV2 at 18p11, in lymphoblastoid cell lines (LCLs) from Japanese patients with bipolar I disorder (BDI). Recently it was reported that no differences were found in NDUFV2 mRNA levels in LCLs of Caucasian BDI patients compared with controls. In this study, we tested the altered expression of NDUFV2 in extended Japanese LCLs and LCLs from different ethnic groups. Similar tendency was found in the current study compared with our previous study, since decreased expression of NDUFV2 in LCLs from Japanese patients with BDI was found (p=0.03). We also found that the expressions of NDUFV2 were up-regulated in those from patients with Japanese bipolar II disorder (p=0.001) and the mRNA levels of this gene were down-regulated in Caucasian SZ (p=0.000001) compared with controls. Furthermore, we revealed that the mRNA expression of NDUFV2 in LCLs cultured with valproate, one of mood stabilizers, were significantly increased compared with controls (p=0.02). Our study presented the further evidence of biological significance of NDUFV2 in BD and SZ.

    Telomere shortening is a biomarker of cellular senescence and is associated with a wide range of age-related disease. Oxidative stress is also associated with physiological aging and several age-related diseases. Non-human studies suggest that variants in oxidative stress genes may contribute to both telomere shortening and biological aging. We sought to test whether oxidative stress-related gene polymorphisms contribute to variance in both telomere length and physical biomarkers of aging in humans. Telomere lengths were calculated for 190 (82 men, 108 women) participants aged 79 years and associations with 384 SNPs, from 141 oxidative stress genes, identified 9 significant SNPS, of which those from 5 genes (GSTZ1, MSRA, NDUFA3, NDUFA8, VIM) had robust associations with physical aging biomarkers, respiratory function or grip strength. Replication of associations in a sample of 318 (120 males, 198 females) participants aged 50 years confirmed significant associations for two of the five SNPs (MSRA rs4841322, p=0.008; NDUFA8 rs6822, p=0.048) on telomere length. These data indicate that oxidative stress genes may be involved in pathways that lead to both telomere shortening and physiological aging in humans. Oxidative stress may explain, at least in part, associations between telomere shortening and physiological aging.

    The mitochondrion, conventionally thought to be an organelle specific to energy metabolism, is in fact multifunctional and implicated in many diseases, including cancer. To evaluate whether mitochondria-related genes are associated with increased risk for prostate cancer, we genotyped 24 single-nucleotide polymorphisms (SNP) within the mitochondrial genome and 376 tagSNPs localized to 78 nuclear-encoded mitochondrial genes. The tagSNPs were selected to achieve > or = 80% coverage based on linkage disequilibrium. We compared allele and haplotype frequencies in approximately 1,000 prostate cancer cases with approximately 500 population controls. An association with prostate cancer was not detected for any of the SNPs within the mitochondrial genome individually or for 10 mitochondrial common haplotypes when evaluated using a global score statistic. For the nuclear-encoded genes, none of the tagSNPs were significantly associated with prostate cancer after adjusting for multiple testing. Nonetheless, we evaluated unadjusted P values by comparing our results with those from the Cancer Genetic Markers of Susceptibility (CGEMS) phase I data set. Seven tagSNPs had unadjusted P < or = 0.05 in both our data and in CGEMS (two SNPs were identical and five were in strong linkage disequilibrium with CGEMS SNPs). These seven SNPs (rs17184211, rs4147684, rs4233367, rs2070902, rs3829037, rs7830235, and rs1203213) are located in genes MTRR, NDUFA9, NDUFS2, NDUFB9, and COX7A2, respectively. Five of the seven SNPs were further included in the CGEMS phase II study; however, none of the findings for these were replicated. Overall, these results suggest that polymorphisms in the mitochondrial genome and those in the nuclear-encoded mitochondrial genes evaluated are not substantial risk factors for prostate cancer.

    Laboratory of Cellular and Molecular Pathophysiology, Centre for Addiction and Mental Health, Toronto, Ontario, Canada.

    Background: The nuclear-encoded mitochondrial complex I subunit gene, NDUFV2, has been implicated in the pathogenesis of bipolar disorder (BD) in Japanese by virtue of association of variants in its promoter with BD and decreased NDUFV2 messenger ribonucleic acid (mRNA) levels in B lymphoblasts (BLCL) in BD patients compared to controls. We sought to determine if these same changes occur in non-Japanese populations and, if so, their relationship to altered basal intracellular Ca(2+) ([Ca(2+)](B)) in BLCL from BD patients.

    Methods: Bipolar disorder patients and healthy subjects included 298 subjects of European Caucasian descent. The 5'-nuclease allelic discrimination TaqMan assay was used to detect selected single nucleotide polymorphisms (SNPs) in promoter, introns and 3'UTR regions, spanning the NDUFV2 gene. NDUFV2 mRNA levels and [Ca(2+)](B) in BLCLs were determined.

    Results: The A allele of the NDUFV2 SNP rs1156044 was significantly associated (Bonferroni-corrected) with BD (p = 0.013) but differed in allele (rs1156044 G allele) from that previously reported as associated with BD. There was a trend for elevated BLCL [Ca(2+)](B) associated with SNP rs977581 in BD patients, but NDUFV2 mRNA levels in BLCLs did not differ between patients and controls, nor represented genotypes.

    Conclusions: While genetic variants of NDUFV2 may increase risk for BD, the role of its altered expression and the link to intracellular Ca(2+) abnormalities in BD remains equivocal.

    Background: Non-pathological cognitive ageing is a distressing condition affecting an increasing number of people in our 'ageing society'. Oxidative stress is hypothesised to have a major role in cellular ageing, including brain ageing.

    Results: Associations between cognitive ageing and 325 single nucleotide polymorphisms (SNPs), located in 109 genes implicated in oxidative stress and/or cognition, were examined in a unique cohort of relatively healthy older people, on whom we have cognitive ability scores at ages 11 and 79 years (LBC1921). SNPs showing a significant positive association were then genotyped in a second cohort for whom we have cognitive ability scores at the ages of 11 and 64 years (ABC1936). An intronic SNP in the APP gene (rs2830102) was significantly associated with cognitive ageing in both LBC1921 and a combined LBC1921/ABC1936 analysis (p < 0.01), but not in ABC1936 alone.

    Conclusion: This study suggests a possible role for APP in normal cognitive ageing, in addition to its role in Alzheimer's disease.

    The electron transport chain enzyme complex I may play a role in Parkinson's disease (PD) pathogenesis. Association studies considering whether or not complex I-relevant gene polymorphisms contribute to PD risk are discordant. We evaluated four complex I-relevant gene polymorphisms alternatively reported to associate and not associate with PD (tRNA(Gln) T4336C, ND1 T4216C, ND2 G5460A, and the NDUFV2 exon 2 C182T transition). Our study included 111 PD subjects and 106 controls in central Virginia. Individuals with at least one copy of the NDUFV2 182T allele were more likely to report a PD family history than non-carriers, but aside from this no positive associations were found. Indeed, the tRNA(Gln) 4336C variant occurred more frequently in controls. We also observed that individuals in both groups often carried more than one of the assayed polymorphisms, and for the first time show bigenomic polymorphic variation (between nuclear and mtDNA complex I subunit genes) commonly occurs within individuals. In an exploratory sub-analysis, more control than case women had an ND1 4216C, NDUFV2 homozygous 182C compound genotype. Complex I compound genotype variation commonly occurs and may explain why particular complex I gene polymorphisms associate with PD in some populations but not others.

  • Association of mitochondrial complex I subunit gene NDUFV2 at 18p11 with schizophrenia in the Japanese population.

    Laboratory for Molecular Dynamics of Mental Disorders, Brain Science Institute, RIKEN, Saitama, Japan.

    Schizophrenia and bipolar disorder share common genetic background. Several loci such as 18p11, 13q32, and 22q11-13 were commonly linked with these diseases. Since mitochondrial dysfunction has been suggested in both of these disorders, NDUFV2 at 18p11, encoding a subunit of the complex I, NADH ubiquinone oxidoreductase, is a candidate gene for these diseases. We previously reported that single nucleotide polymorphisms (SNPs) in the upstream region of NDUFV2 were associated with bipolar disorder in Japanese. The association of haplotype consisting of two SNPs, -3542G > A and -602G > A, with bipolar disorder was also seen both in Japanese and the National Institute of Mental Health Pedigrees trios. In this study, 2 polymorphisms, -3542G > A and -602G > A, were investigated in 229 schizophrenic patients as compared with controls. Individual genotypes were not associated with schizophrenia. However, the haplotype consisting of these two SNPs were significantly associated with schizophrenia. These results suggested that inter-individual variation of the genomic sequence of the promoter region of NDUFV2 might be a genetic risk factor common to bipolar disorder and schizophrenia.

    Protein-protein interaction maps provide a valuable framework for a better understanding of the functional organization of the proteome. To detect interacting pairs of human proteins systematically, a protein matrix of 4456 baits and 5632 preys was screened by automated yeast two-hybrid (Y2H) interaction mating. We identified 3186 mostly novel interactions among 1705 proteins, resulting in a large, highly connected network. Independent pull-down and co-immunoprecipitation assays validated the overall quality of the Y2H interactions. Using topological and GO criteria, a scoring system was developed to define 911 high-confidence interactions among 401 proteins. Furthermore, the network was searched for interactions linking uncharacterized gene products and human disease proteins to regulatory cellular pathways. Two novel Axin-1 interactions were validated experimentally, characterizing ANP32A and CRMP1 as modulators of Wnt signaling. Systematic human protein interaction screens can lead to a more comprehensive understanding of protein function and cellular processes.

    Laboratories for Molecular Dynamics of Mental Disorders, Brain Science Institute, RIKEN, Wako, Saitama, Japan.

    Background: Linkage with 18p11 is one of the replicated findings in molecular genetics of bipolar disorder. Because mitochondrial dysfunction has been suggested in bipolar disorder, NDUFV2 at 18p11, encoding a subunit of the complex I, reduced nicotinamide adenine dinucleotide (NADH)ubiquinone oxidoreductase, is a candidate gene for this disorder. We previously reported that a polymorphism in the upstream region of NDUFV2, -602G> A, was associated with bipolar disorder in Japanese subjects; however, functional significance of -602G> A was not known.

    Methods: We screened the further upstream region of NDUFV2. We performed a case-control study in Japanese patients with bipolar disorder and control subjects and a transmission disequilibrium test in 104 parent and proband trios of the National Institute of Mental Health (NIMH) Genetics Initiative pedigrees. We also performed the promoter assay to examine functional consequence of the -602G> A polymorphism.

    Results: The -602G> A polymorphism was found to alter the promoter activity. We found that the other haplotype block surrounding -3542G> A was associated with bipolar disorder. The association of the haplotypes consisting of -602G> A and -3542G> A polymorphisms with bipolar disorder was seen both in Japanese case-control samples and NIMH trios.

    Conclusion: Together these findings indicate that the polymorphisms in the promoter region of NDUFV2 are a genetic risk factor for bipolar disorder by affecting promoter activity.

    The National Institutes of Health's Mammalian Gene Collection (MGC) project was designed to generate and sequence a publicly accessible cDNA resource containing a complete open reading frame (ORF) for every human and mouse gene. The project initially used a random strategy to select clones from a large number of cDNA libraries from diverse tissues. Candidate clones were chosen based on 5'-EST sequences, and then fully sequenced to high accuracy and analyzed by algorithms developed for this project. Currently, more than 11,000 human and 10,000 mouse genes are represented in MGC by at least one clone with a full ORF. The random selection approach is now reaching a saturation point, and a transition to protocols targeted at the missing transcripts is now required to complete the mouse and human collections. Comparison of the sequence of the MGC clones to reference genome sequences reveals that most cDNA clones are of very high sequence quality, although it is likely that some cDNAs may carry missense variants as a consequence of experimental artifact, such as PCR, cloning, or reverse transcriptase errors. Recently, a rat cDNA component was added to the project, and ongoing frog (Xenopus) and zebrafish (Danio) cDNA projects were expanded to take advantage of the high-throughput MGC pipeline.

    Laboratory for Molecular Dynamics of Mental Disorders, Brain Science Institute, RIKEN, Saitama, Japan.

    Linkage of bipolar disorder with 18p11 has been replicated by several investigators. A nuclear-encoded mitochondrial complex I subunit gene, NDUFV2, is one of the candidate genes in this locus, since the possible pathophysiological significance of mitochondrial dysfunction in bipolar disorder has been suggested. The objective of our study was to clarify the association between the NDUFV2 gene and bipolar disorder. We performed the real-time quantitative reverse transcription polymerase chain reaction (RT-PCR) for NDUFV2 mRNA expression in lymphoblastoid cell lines derived from patients with bipolar disorder and healthy controls. We also screened novel polymorphisms using denaturing high performance liquid chromatography (D-HPLC) and PCR-direct sequencing method. Detected five single nucleotide polymorphisms (SNPs) were genotyped. A decrease of the expression level of NDUFV2 gene was found in patients with bipolar I disorder compared with controls (P = 0.006). We also found that the haplotype frequencies of the four polymorphisms in the upstream region of NDUFV2 were significantly different between bipolar disorders and controls (P = 0.0001). Our findings suggest that polymorphisms of the NDUFV2 gene may be one of the genetic risk factors for bipolar disorder.

    Respiratory chain complex I deficiencies represent a genetically heterogeneous group of diseases resulting from mutations in either mitochondrial or nuclear DNA. Combination of denaturing high performance liquid chromatography and sequence analysis allowed us to show that a 4-bp deletion in intron 2 (IVS2+5_+8delGTAA) of the NDUFV2 gene (encoding NADH dehydrogenase ubiquinone flavoprotein 2) causes complex I deficiency and early onset hypertrophic cardiomyopathy with trunk hypotonia in three affected sibs of a consanguineous family. The homozygous mutation altering the consensus splice-donor site of exon 2 resulted in 70% decreased NDUFV2 protein and complex I deficiency. While mutation in a number of genes encoding complex I subunits essentially result in neurological symptoms, this first mutation in NDUFV2 is strikingly associated with cardiomyopathy, as previously observed in the unique case of NDFUS2 mutations.

    NADH:ubiquinone oxidoreductase (complex I) is an extremely complicated multiprotein complex located in the inner mitochondrial membrane. Its main function is the transport of electrons from NADH to ubiquinone, which is accompanied by translocation of protons from the mitochondrial matrix to the intermembrane space. Human complex I appears to consist of 41 subunits of which 34 are encoded by nDNA. Here we report the cDNA sequences of the hitherto uncharacterized 8 nuclear encoded subunits, all located within the hydrophobic protein (HP) fraction of complex I. Now all currently known 41 proteins of human NADH:ubiquinone oxidoreductase have been characterized and reported in literature, which enables more complete mutational analysis studies of isolated complex I-deficient patients.

    We analyzed the gene encoding the 24-kDa subunit of mitochondrial complex I, which has been implicated in the pathogenesis of Parkinson disease (PD). We set out to identify a polymorphism in the 24-kDa subunit gene (NDUFV2) in patients with PD and determine whether genetic polymorphism of this gene is associated with a higher risk of PD. The subjects comprised 126 patients with PD, and the control group comprised 113 unrelated individuals without neurodegenerative disorders. A novel polymorphism (Ala29Val) in the mitochondrial targeting sequence of NDUFV2 was found in patients with PD. The distribution of the three genotypes was significantly different between the two groups (chi 2 = 7.53, df = 2, P = 0.023). The frequency of homozygotes for the mutation was significantly higher in PD patients (23.8%) than in control subjects (11.5%, Fisher's exact test, P = 0.0099 < 0.01). The risk of developing PD associated with homozygosity for this mutation was calculated as 2.40 (95% CI: 1.18-4.88). NDUFV2 constitutes one genetic risk factor for PD, and the mutation may well be a cause of complex I deficiency in this disease.

    At least 34 complex I subunits of the electron transport chain are encoded by the nuclear genome, but only 14 of these have been mapped in the human. To rapidly map additional subunits, we have performed a combination of database mining and direct "wet" experimentation to identify intron and/or 5' upstream genomic DNA regions for 16 complex I genes. Wet experimentation was applied to 5 genes, and involved direct PCR amplification of introns by inter-exon PCR or splinkerette based PCR walking. Database mining was applied to 11 genes, and entailed the identification of incompletely spliced mRNAs and genomic CpG island clone sequences. This data was in files that carried no documentary description of the non-exon regions. Non-exon sequences were thus derived for 15 complex I genes and used to design functional gene specific PCR assays. Radiation hybrid mapping of these PCRs located 15 complex I genes to chromosomes l, 4, 5 (2 genes), 7 (2 genes), 8, 9 (2 genes), 11, 14, 16 (2 genes), 18, and 19.

    The structural organization of the entire human nuclear encoded gene for the 24-kDa iron-sulfur subunit of mitochondrial NADH-ubiquinone oxidoreductase (Complex I) and its chromosomal localization were determined. The gene contains 8 exons spanning 31.5 kb. The 5' flanking region sequenced lacks typical CAAT and TATA boxes but contains three putative GC boxes and there is one GC box at the beginning of the first intron. The sequences matching completely with the NRF-1 binding site and Mt elements were not identified in the flanking region. This gene was assigned to human chromosome 18 at region p11.3, by fluorescent in situ hybridization.

  • Molecular cloning and characterization of the active human mitochondrial NADH:ubiquinone oxidoreductase 24-kDa gene (NDUFV2) and its pseudogene.

    Two distinct loci for the 24-kDa subunit of the mitochondrial NADH:ubiquinone oxidoreductase (complex I of the respiratory chain) were detected in the human genome: a transcribed gene from chromosome 18 and an inactive locus on chromosome 19. Cosmid clones containing the functional gene (NDUFV2) and the pseudogene (NDUFV2P1) were isolated. The NDUFV2 gene spans approximately 20 kb and contains 8 exons. Refined mapping of both NDUFV2 genes by FISH resulted in an assignment of the NDUFV2 gene to 18p11.2-p11.31 and of the NDUFV2P1 gene to 19q13.3-qter. The nucleotide sequence of the NDUFV2P1 pseudogene differs from the cDNA sequence by the lack of the methionine initiator codon, an additional 165 bp of the first intron sequence, and a 1-nucleotide deletion.

  • Mitochondrial NADH-ubiquinone reductase: complementary DNA sequences of import precursors of the bovine and human 24-kDa subunit.

    The 24-kDa subunit of mitochondrial NADH-ubiquinone reductase (complex I) is an iron-sulfur protein that is present in the flavoprotein or NADH dehydrogenase II subcomplex. It is a nuclear gene product and is imported into the organelle. A group of human patients with mitochondrial myopathy have been shown to have reduced levels of subunits of complex I in skeletal muscle mitochondria, and in one patient the 24-kDa subunit appears to be absent (Schapira et al., 1988). To investigate the genetic basis of this type of myopathy, cDNA clones have been isolated from a bovine library derived from heart and liver mRNA by hybridization with two mixtures of 48 synthetic oligonucleotides 17 bases in length that were designed on the basis of known protein sequences. The recombinant DNA sequence has been determined, and it encodes a precursor of the mature 24-kDa protein. The N terminus of the mature protein is preceded by a presequence of 32 amino acids that has properties that are characteristic of mitochondrial import sequences. The sequence of the mature protein deduced from the cDNA contains a segment of nine amino acids that was not determined in an earlier partial protein sequence analysis. The bovine clone has been employed as a hybridization probe to identify cDNA clones of the human homologue of the 24-kDa protein. Its DNA sequence has also been determined, and it codes for a protein that is closely related to the bovine protein.(ABSTRACT TRUNCATED AT 250 WORDS)
