OBJECTIVE To estimate the genetic influence on the occurrence of radiologic osteoarthritis (ROA) in the knees, hips, and hands and disc degeneration of the spine in the general population. METHODS A random sample of 1,583 individuals was drawn to estimate the prevalence of ROA and disc degeneration in the general population. Of 118 probands with multiple(More)
Osteoarthritis affects the whole joint structure with progressive changes in cartilage, menisci, ligaments and subchondral bone, and synovial inflammation. Biomarkers are being developed to quantify joint remodelling and disease progression. This article was prepared following a working meeting of the European Society for Clinical and Economic Aspects of(More)
OBJECTIVE Identify gene expression profiles associated with OA processes in articular cartilage and determine pathways changing during the disease process. METHODS Genome wide gene expression was determined in paired samples of OA affected and preserved cartilage of the same joint using microarray analysis for 33 patients of the RAAK study. Results were(More)
OBJECTIVE To identify novel gene expression networks in blood of osteoarthritis patients compared to controls. METHODS A comprehensive exploration of gene expression in peripheral blood was performed by microarray analysis for a subset of osteoarthritis patients from the Genetics osteoARthritis and Progression (GARP) study in comparison with sex and(More)
OBJECTIVE To study the role of the interleukin-1 beta gene (IL1B) and the IL-1 receptor antagonist gene (IL1RN) in relation to the occurrence of radiographic osteoarthritis (ROA) in the hip, knee, and hand and disc degeneration of the spine. METHODS The study population consisted of a random sample of 886 subjects (ages 55-65 years) from a(More)
OBJECTIVE Several research groups have examined osteoarthritis (OA) association with Interleukin-1 (IL-1) region markers and haplotypes. The results have been suggestive for hand OA, negative for knee OA, and conflicting for hip OA. DESIGN Our aim was to address conflicts employing meta-analytical methods on data from 1238 European-descent cases with(More)
OBJECTIVES To investigate how the genetic susceptibility gene DIO2 confers risk to osteoarthritis (OA) onset in humans and to explore whether counteracting the deleterious effect could contribute to novel therapeutic approaches. METHODS Epigenetically regulated expression of DIO2 was explored by assessing methylation of positional CpG-dinucleotides and(More)
Twin studies suggest that genetic factors play a substantial role in anorexia nervosa (AN) and self-induced vomiting (SV), a key symptom that is shared among different types of eating disorders (EDs). We investigated the association of 25 single nucleotide polymorphisms (SNPs), capturing 71-91% of the common variance in candidate genes, stathmin (STMN1),(More)
BACKGROUND AND OBJECTIVES Chronic widespread pain (CWP) is a common disorder affecting ∼10% of the general population and has an estimated heritability of 48-52%. In the first large-scale genome-wide association study (GWAS) meta-analysis, we aimed to identify common genetic variants associated with CWP. METHODS We conducted a GWAS meta-analysis in 1308(More)
