Project description:To reveal the risk CNVs of SZ in Chinese population, we recrited and enrolled 100 Chinese family trios with a schizophrenia affected children and both of their father and mother. SZ was diagnosed according to DSM-IV criteria by two independent psychiatrists. There gDNA we screen the genome-wide CNV using Agilent SurePrint G3 Human CGH Microarray Kit (1x1M) and Agilent sex-matched human DNA was used as reference. The CNV were called by ADM-2 statistical algorithms with a threshold of 6.0. We compared the burden of large rare CNVs and found that SZ probands carried more duplications and less deletions. Furtherly, we performed familial inheritance analysis of transmission disequilibrium and de novo CNV detection, validated several associated CNV loci with SZ susceptibility and also identify eight novel loci conferring risk of SZ

Project description:Study objectives: Acute sleep deprivation affects both central and peripheral biological processes. Prior research has mainly focused on specific proteins or biological pathways that are dysregulated in the setting of sustained wakefulness. This pilotexploratory study’s objective wasaimed to provide a comprehensive view of the biological processes and proteins impacted by acute sleep deprivation in both plasma and cerebrospinal fluid (CSF). Methods: We collected plasma and CSF from human participants during one night of sleep deprivation and control normal sleep conditions. 1300 proteins were measured at hour 0 and hour 24 using a high-scale aptamer-based proteomics platform (SOMAomascan) and a systematics biological database tool (Metascape) was used to reveal dysregulated biological pathways. Results: Acute sleep deprivation lead to opposite effects in plasma and CSF, decreasingdecreased the number of upregulated and downregulated differential protein expression and biological pathways and proteins in plasma but increased upregulated and downregulated protein and biological pathwayssing them in CSF. Predominantly affected pProteins and n pathways were associated with that were predominantly affected by sleep deprivation included immune response, inflammation, phosphorylation, membrane signaling, cell-cell adhesion, and extracellular matrix organization. Conclusions: The identified modification across biofluids adds to evidence that acute sleep deprivation has important impacts on biological pathways and proteins that can negatively affect human health. As a hypothesis-driving study, these findings may help with the exploration of novel mechanisms that mediate sleep loss and associated conditions, drive the discovery of new sleep loss biomarkers, and ultimately aid in the identification of new targets for intervention to human diseases.

Project description:Using high-throughput antibody microarray, through cross-sectional sample detection and verification of samples that had undergone physical changes over time, it was found that people with balanced constitution and dampness constitution in Chinese medicine showed differences in serum protein expression. The differences were expressed as the level changes of 19 proteins such as Dectin-2, Siglec-7, AIF and TACI. The research results provided the basis for the scientific expression of traditional Chinese medicine (TCM) constitution.

Project description:Objective: Intellectual disability (ID) is often sporadic, and its complex etiology can make clinical diagnosis difficult. The aims of this study were to detect genomic copy number variations (CNVs) in Chinese patients with ID, and to analyze the correlation between pathogenic CNVs and clinical phenotypes. Methods: After excluding cases of ID caused by chromosomal aneuploidy, metabolic dysfunction, or environmental factors, we enrolled 60 patients with moderate to severe ID. We performed karyotype and single-nucleotide polymorphism (SNP) array analyses for all patients. Finally, we analyzed the relationship between CNVs and phenotype using CNV databases and genotype-phenotype comparisons. Results: Karyotype analysis showed chromosomal terminal abnormalities in five patients and balanced translocations in two patients. Using SNP array analysis for 60 patients, we detected 87 CNVs in 45 patients, which included 16 pathogenic CNVs in 12 patients with a diagnostic yield of 20.0% (12/60). In one patient, we observed 14 regions of homozygosity > 10 Mb to 266 Mb. We detected a large deletion at 16q22.2 or 3q24q25 in each of two patients, in regions that have not previously been associated with specific syndromes. One case carried a 210-kb deletion at 1q21, including only one coding gene, LPPR4, which may be a candidate gene for the ID phenotype. Conclusions: Use of the genome-wide array screening method can improve the detection rate of CNVs, reveal chromosomal abnormalities that have not been well characterized by cytology, and provide a new way to locate genes for patients with the ID phenotype. However, interpretation of CNVs remains a major challenge, which is why we believe that publicly shared data on CNVs and phenotypes can create a rich database of information.

Project description:Identification of genes differentially expressed between human monocyte-macrophages generated in the presence of either GM-CSF (termed M1) or M-CSF (termed M2) Human peripheral blood monocytes from three independent healthy donors (#1, #2 and #3) were isolated by anti-CD14-labeled magnetic microbeads. CD14+ monocytes were cultured for 7 days in RPMI 10% FCS containing either GM-CSF or M-CSF. Total RNA from each condition was extracted and purified using the RNeasy kit (Qiagen). Labelled RNA was used as hybridization probes on human Codelink Whole genome Bioarray. All experimental procedures were performed following manufacturer instructions. Microarrays were scanned with a GenePix 4000B (Axon Instruments) scanner. Scanned images and raw data were processed using the Codelink Expression Software.

Project description:Neprilysin (NEP) is a principal peptidase involved in the degradation of β-amyloid (Aβ), and as such its encoding gene (MME) has been the target of numerous genetic association studies on Alzheimer disease. Here, in order to attempt replication of previous findings we have investigated several single nucleotide polymorphisms (SNPs) that have been claimed to be associated with AD. A key feature of the present study is the complementary investigation of both AD risk and quantitative measures of AD severity, including cerebrospinal (CSF) fluid levels of AP1-42. In contrast to the effects of APOE, none of these measures are detectably influenced by genetic polymorphism in the MME region. We thus, fail to find support for previous results suggesting that MME impacts AD.
