HumanMethylation450 (450k) data for 79 rheumatoid arthritis disease discordant monozygotic twin pairs

ABSTRACT: This project contains genome-wide DNA methylation data generated using the HumanMethylation450 BeadChip (Illumina), for 79 rheumatoid arthritis (RA) discordant monozygotic twin pairs. By investigating disease discordant monozygotic twins, DNA methylation can be assessed without the confounding influence of genetic heterogeneity which often affects case-control epigenome-wide association studies of common diseases. Twins were recruited from two cohorts; Arthritis Research UK in Manchester and TwinsUK in London.

Epigenome wide association study of response to methotrexate in early rheumatoid arthritis patients

Project description:The aim of the study is to identify differentially methylated positions (DMPs) and regions (DMRs) that predict response to Methotrexate (MTX) in early rheumatoid arthritis (RA) patients. DNA from baseline peripheral blood mononuclear cells was extracted from treatment naive RA patients. DNA methylation, quantified using the Infinium MethylationEPIC, was assessed in relation to response to MTX (combination) therapy (deltaDAS28) over the first 3 months in 69 RA patients.

Intra-MZ pair discordance and longitudinal variation of whole-genome scale DNA methylation in adults

Project description:In this study, we used Illumina Infinium HumanMethylation450 Beadchips to compare DNA methylation profiles in blood from 10 pairs of MZ twins and 8 individuals recruited at 0, 3, 6, and 9 months. MZ Group (Group A) contained 10 pairs of MZ twins ranging from 23 to 74 years old, including 8 female and 12 male subjects.Longitudinal study group (Group B) included a pair of MZ (male) twins and 6 unrelated individuals (3 male, 3 female), aged from 24 to 39. Except subject H, all participants in Longitudinal study group (Group B) were recalled every 3 months for 9 months (0, 3, 6, and 9 m). Subject H was studied only at 0, 6, and 9 months. Bisulphite converted DNA from the 60 samples were hybridised to the Illumina Infinium 450k Human Methylation Beadchip

Autoantibody profiling of sera from individuals with Systemic Lupus Erythematosus (SLE) by protein microarray

Project description:We developed a protein microarray to identify autoantigens in Systemic Lupus Erythematosus (SLE). Baculovirus-Sf9 cell expression system was used to create a protein microarray with 1543 full-length human proteins expressed with a biotin carboxyl carrier protein (BCCP) folding tag. We assayed sera from UK and USA SLE individuals (total n=277), age/ancestry matched control cohorts (n=280) and a confounding disease cohort (n=92).

circulating microRNA expression profiles of Kashin-Beck disease, osteoarthritis and rheumatoid arthritis

Project description:We compared the circulating microRNA expression profiles of KBD, osteoarthritis (OA), rheumatoid arthritis (RA) and healthy controls. Blood specimens were collected from 3 KBD patients, 3 OA patients, 3 RA patients and 3 healthy controls. miRNAs expression profiling was performed using Exiqon miRCURY LNATM miRNAs Array.

Osteoarthritic Bone Marrow Lesions exhibit cystic, vascular, osteogenic and chondrogenic changes with upregulated neuronal, inflammatory and matrix gene expression signatures

Project description:Bone marrow lesions (BML) are well described in osteoarthritis (OA) using magnetic resonance imaging (MRI) and associate with pain however, little is known about their role in disease process and pattern of gene expression within the lesions. This study evaluated the gene expression profile of OA BML (n=14) in comparison to normal bone (n=10) by microarray profiling. MR imaging and the MOAKS scoring was used to locate lesions and the scaled axial images were used to sample BMLs. The bone tissue controls were harvested from participants undergoing surgery following trauma.

Illumina HumanmethylationEPIC array analysis in early synovial fibroblasts of RA patients before diagnosis

Project description:In the current study, we compared DNA methylation patterns using the Illumina 850k array technology between normal synovial fibroblasts and synovial fibroblasts from early (veRASF) and late stages of RA (estRASF) and transient, resolving arthritis (rSF). In doing so, we obtained a detailed view of changes in DNA methylation that occur during the development of RA from the earliest clinically apparent stages to established RA with its typical signs and symptoms.

Cell-specific methylation patterns in TB patients and household contacts

Project description:Monocytes and granulocytes were isolated from blood of TB patients and household contacts. DNA was isolated and methylation profile was measured using Illumina HumanMethylation450. House-hold contacts were matched to TB patients by gender and age. From each subject, two profiles (monocytes and granulocytes) were collected.

A novel six-CpGs signature predicts clinical outcome in glioblastomas

Project description:We aimed to identify a clinically useful biomarker using DNA methylation-based information to optimize the management of glioblastoma (GBM) patients. We identified a novel six-CpGs signature that predicts the clinical outcome in GBM. The methylation profiling of 79 GBM patients has been used as a validation cohort to demonstrate the performance and the robustness of the identified six-CpGs signature. The status of the âMGMTâ biomarker, traditionally used by clinicians to predict survival in GBM, is also indicated per sample.
