The transcriptional modulator H2AFY marks Huntington's disease activity in men and mice

ABSTRACT: To accelerate the development of disease-modifying therapeutics for Huntington’s disease (HD), a dynamic biomarker of disease activity and treatment response is critically needed. Venous cellular whole blood from 8 patients with Huntington's disease (HD) and 6 control subjects were collected in PAXgene tubes (Wiagen, Valencia, CA). RNA was isolated from whole blood using the PAXgene blood RNA kit (Qiagene) with DNase treatment. The biotinylated complementary RNA was fragmented and hybridized to Affymetrix human genome U133A microarrays. The Affymetrix .CEL files were normalized to “all probe sets” in a standardized matter, and scaled to 100 by the MAS5 5.0 algorithm implemented in the Bioconductor package.

Huntington disease (HD) is a progressive neurodegenerative disease that affects 30,000 individuals in North America. Treatments that slow its relentless course are not yet available, and biomarkers that can reliably measure disease activity and therapeutic response are urgently needed to facilitate their development. Here, we interrogated 119 human blood samples for transcripts associated with HD. We found that the dynamic regulator of chromatin plasticity H2A histone family, member Y (H2AFY) is ...[more]

Hdac4 interactome in Huntington's Disease

Project description:Hdac4 has been found to modulate symptoms in Huntington's Disease (HD) mouse models through an uknown mechanism unrelated to any enzymatic activity. We investigated the protein-protein interactions to gain insight into the role of Hdac4 in HD.

Transcriptomics data of blood and brain from the YAC128 Huntington's disease mouse model [brain]

Project description:Therapeutic development for Huntington's disease (HD) would benefit from a method to monitor disease progression and treatment efficacy, ideally using blood biomarkers. Previously, HD-specific signatures were identified in human blood which adequately represented signatures in human brain, showing biomarker potential. Since drug candidates are normally first screened in rodent models, we aimed to identify HD-signatures in blood and brain of YAC128 HD mice and validate these with our previously identified human signatures. In both brain and blood, we identified HD-associated modules using Weighted Gene Co-expression Network Analysis (WGCNA) representing various biological processes previously associated with HD. Disease-related processes in blood and brain showed substantial overlap, including processes related to protein modification, cell cycle, RNA splicing, nuclear transport and vesicle-mediated transport. Moreover, the disease-associated processes shared between mouse blood and brain were highly comparable to those previously identified in human blood and brain. In addition to shared pathology, we identified HD-associated blood modules showing blood-specific pathology.

Huntington's disease biomarker progression profile identified by transcriptome sequencing in peripheral blood

Project description:In this study we investigated the suitability of blood to identify HD transcriptomic biomarkers, validated the outcome in an independent cohort and derived a first empiric panel of biomarkers capable of predicting HD motor scores. Finally we examined whether patient gene expression profiles could provide information about HD affected biological pathways. Examination of differentially expressed genes in peripheral whole blood using linear modelling of gene expression data (3 DGE) against UHDRS total motor scores of Huntington's Disease mutation carriers and controls.

Differential expression analysis of miRNAs expressed in blood and CSF of Huntington's disease [miRNA array]

Project description:Huntington’s disease (HD) is an autosomal-dominant neurodegenerative disorder caused by the CAG expansion in the Huntingtin (HTT) gene. Several studies have shown the potential of microRNAs as biomarkers in neurodegenerative diseases. However, no bona fide microRNAs have been identified as promising diagnostic biomarkers for HD. As part of the PREDICT-HD project, here we performed NanoString on blood samples of 115 pre-manifest HD cases and 111 controls in an effort to provide promising biomarkers for the diagnostic of HD or the disease processes tracking. The results showed that five miRNAs (miR-1252, miR-433, miR-553, miR-138-5p and miR-2053) are significantly differentially expressed in pre-manifest gene-positive HD cases vs. gene-negative controls. We also explored the miRNAs associated with HD severity by correlating the miRNA expression with CAP scores of 115 pre-manifest HD samples and found that 41 and 24 miRNAs are negatively and positively correlated with CAP scores significantly. Furthermore, target gene set of miR-138 and miR-433 , its co-expressed mRNAs in ROSMAP, and differentially expressed mRNAs of HD reveal four overlap genes (CASP7, CNOT6L, TMED and FERMT2). In summary, our study provides new insights into biomarker of Huntington’s disease by analyzing the cross-sectional miRNA expression data in blood.
