Analysis of peripheral blood mononuclear cells (PBMCs) from osteoarthritis (OA) patients. Patients participated in the Genetics osteoARthritis and Progression (GARP) study. Results provide insight into the feasibility of using gene expression profiling of PBMCs to detect the onset of OA.

(Submitter supplied) By performing a comprehensive exploration of peripheral blood by microarray analysis from a subset of the Genetics osteoARthritis and Progression (GARP) study in comparison with sex and age-matched healthy controls we have identified disease specific gene expression networks. Our data hint at the relevance of apoptosis as an etiological factor in osteoarthritis onset, thereby qualifying expression profiling of blood as a useful tool to understand the underlying molecular mechanisms of osteoarthritis.

(Submitter supplied) One of the top priorities of the swine industry worldwide is to decrease the susceptibility of its animals to infectious diseases. There is therefore now an increased focus on the production of more “robust” animals, which have lower susceptibility to a broad range of infectious diseases. One general measure of immune competence is the proliferative response of peripheral blood mononuclear cells (PBMC) to mitogenic stimulation. more...

(Submitter supplied) Purpose: The goal of the study was to integrate verified signals from previous genetic association studies with gene expression and pathway analysis for discovery of new candidate genes and signalling networks, relevant for rheumatoid arthritis (RA). Method:RNA-seq based expression analysis of 377 genes from previously verified RA-associated loci was performed in blood cells from 5 newly diagnosed, non-treated RA patients, 7 patients with treated RA and 12 healthy controls. more...

(Submitter supplied) The aim of this study was to compare gene expression between two pathological groups of human synovial fibroblasts (SF) from rheumatoid arthritis (RA) and osteoarthritis (OA) synovial tissues with normal SF from healthy individuals (HSF). We used microarray expression profiling in SF cultured from OA, RA and normal synovial tissues. We found larger numbers of transcripts with differential expression in OASF compared to the other groups than in RASF compared to HSF. more...

(Submitter supplied) The aim of this study is to identify, for the first time, the genome-wide DNA methylation profiles of human articular chondrocytes from OA and healtly cartilage samples. Genome wide DNA methylation profiling of normal and osteoarthritic samples. The Illumina Infinium 27k Human DNA methylation Beadchip v1.2 was used to obtain DNA methylation profiles across approximately 27,000 CpGs in cartilage knee samples. more...

(Submitter supplied) We had previously demonstrated an increased proapoptotic effect of Imatinib (STI571) in combination with Amifostine (AMI) in K562 cell line. In this study we used genomic scale gene expression profiling to monitor changes at transcriptional level in K562 cells during the treatment with AMI+STI571. We identified a transcriptional repressor of survival genes, known as BTF, which triggers a pro-apoptotic signal, potentially helpful to overcome the resistance to STI571. more...

(Submitter supplied) The purpose of our study was to better understand the genetic mechanism of oncogenesis for human colorectal cancer and to identify potential new tumour markers of use in clinical practice. Results: Comparing cancerous tissues with normal colonic mucosa we identified 584 known genes (3%) differentially expressed to a significant degree (p<0.001). Many of the transcripts that were more abundant in tumours than in non-neoplastic tissues appear to reflect important events for colon carcinogenesis. more...
