Predictive potential of circulating Ube2h mRNA as an E2 ubiquitin-conjugating enzyme for diagnosis or treatment of Alzheimer’s disease

ABSTRACT: Neurodegenerative disorders are status in which neuronal cell death, miscommunications between synapse, and abnormal accumulation of proteins in the brain. Alzheimer’s disease (AD) is one of the age-related disorders which is most common degenerative disorders today, and strongly involved memory consolidation and cognitive in the brain. Amyloid-β and tau proteins are trigger for AD pathogenesis, and usually use for AD candidate biomarkers in the clinical research. Especially, clinical exam, brain imaging and molecular biological methods are being used to diagnosis for AD. Genome-wide association study (GWAS) is new biomedical method, and use contribute to understanding of many human diseases included brain diseases. Here, we identified ubiquitin conjugating enzyme E2 (Ube2) gene expression in the neuron through GWAS. The subfamilies of Ube2 genetic expression and inborn errors affect ubiquitin proteasome system (UPS) leading to protein degradation in the brain. We found that only Ube2h mRNA transcription was significantly increased in the blood from AD, however we did not find change of Ube2 subfamily genes expression in the blood and brain tissue. These data may provide information of diagnosis or clinical approach, and suggest that cell-free circulating Ube2h mRNA is novel potential biomarker for AD.

Diagnosis of Alzheimer's disease specific phospholipase c gamma-1 SNV by deep-learning based approach for high throughput screening

Project description:Alzheimer’s disease (AD) is a multifactorial disease which is caused by inherited autosomal recessive as familial and late-onset as non-familial changes. However, the genetics of AD underlining variation or mutation are not well understood. Exon skipping through the occurrence of the unpredicted genetic events leads to variation of translation, but the event does not can be exploited for AD diagnosis. We identified a gene as phospholipase c gamma-1 (PLCγ1) with severe genetic modification in AD through deep-learning based high throughput screening which showed single nucleotide variants (SNVs). Genome-wide association study (GWAS) data from AD mouse model demonstrated that AD specific novel SNVs are preferentially occurred H3K27ac accumulated region at PLCγ1 gene body during the brain development. Moreover, exon skipping in mature mRNA was caused by single nucleotide insertion at 27th exon of PLCγ1 gene. In addition, we show mutation site was evolutionally conserved in various species included human which means important region for homeostasis. Collectively, our findings suggest the genetic variation and possibility of diagnosis potent of PLCγ1 for AD.

Transcriptome-wide expression analysis of pooled brain samples of patients with Alzheimer's disease compared to controls

Project description:Brain tissue of 3 patients with Alzheimer's disease (AD) and 3 healthy controls dying without any history of neurological or psychiatric illness was used. The diagnosis of AD was made on the basis of both clinical and neuropathological evidence according to the criteria of the International Working Group (IWG) for New Research Criteria for the diagnosis of AD in the revision of 2014 (IWG-2),16 the NIA-AA diagnostic criteria in the revision of 201117 and the NIA-AA guidelines for the neuropathological assessment of AD. Only cases with typical AD according to IWG-2 criteria were included. Transcriptome-wide expression of AD and healthy control samples was assessed with Affymetrix Human Whole Genome Tiling Array 1.0 Set.

Human iPSC-derived microglia are genetically relevant to Alzheimer’s disease

Project description:Microglia is a primary brain immune cell type that has been implicated in the pathogenesis of neurodegenerative disorders such as Alzheimer’s disease (AD) and neurodevelopmental disorders such as schizophrenia. Generating microglia from human induced pluripotent stem cells (hiPSC) has become an attractive approach to study the microglia-mediated causal mechanism of AD. Among other methods, Brownjohn et al. recently developed a particularly efficient and simple hiPSC-derived microglia (iMG) protocol. However, the transferability of this method to other labs, the transcriptomic similarity of these iMG to primary adult microglia, and their genetic relevance to AD remain unclear. With two hiPSC lines, we demonstrated that the Brownjohn method can efficiently give rise to iMG that were morphologically and functionally like microglia. Our pure iMG were also transcriptionally similar to previously reported iMG lines, as well as fetal and adult microglia. More importantly, we further showed the genetic relevance of iMG to AD using cell type-specific gene expression to partition disease heritability. Contrasting with neuronal and immune cell types, our iMG and several primary microglia and microglia-like cell types were all significantly enriched for AD relevant GWAS loci. These results supported the use of iMG as a valid human cellular model for understanding AD disease progression and a feasible mechanism for generation of AD patient-specific cell types for more precise in vitro analyses, and potentially more effective clinical care.

Expression data from human brain anterior cingulate cortex - including control samples and samples with major depression disorders (20 samples MD2_ACC)

Project description:Major depressive disorder is a heterogeneous illness with a mostly uncharacterized pathology. Large scale gene expression (transcriptome) analysis and genome-wide association studies (GWAS) for single nucleotide polymorphisms have generated a considerable amount of gene- and disease-related information, but heterogeneity and various sources of noise have limited the discovery of disease mechanisms. As systematic dataset integration is becoming essential, we developed methods and performed meta-clustering of gene coexpression links in 11 transcriptome studies from postmortem brains of human subjects with major depressive disorder (MDD) and non-psychiatric control subjects. We next sought enrichment in the top 50 meta-analyzed coexpression modules for genes otherwise identified by GWAS for various sets of disorders. One coexpression module of 88 genes was consistently and significantly associated with GWAS for MDD, other neuropsychiatric disorders and brain functions, and for medical illnesses with elevated clinical risk of depression, but not for other diseases (See publication for details). 20 total samples in 10 pairs were analyzed in postmortem tissue from the anterior cingulate cortex.
