Differential gene expression profiles in peripheral ...
The genes had different expression between healthy people and acute myocardial infarction.We aimed to identify the differentially expressed genes involved in acute myocardial infarction in Northeast Chinese Han people.We used microarrays to detail the global programme of gene expression to identify the differentially gene between the patients with acute myocardial infarction and healthy people in Northeast Chinese Han people

Mutual Antagonistic Relationship Between Prostagland...
PGE2 is a major mediator of inflammation and is present at high concentrations in the synovial fluid of rheumatoid arthritis (RA) patients. PGE2, acting through the EP4 receptor, has both pro- and anti-inflammatory roles in vivo. To shed light on this dual role of PGE2, we investigated its effects in whole blood and in primary human fibroblast-like synoviocytes. Gene expression analysis in human leukocytes, confirmed at the protein level, revealed an EP4-dependent inhibition of the expressio...

Integrated Network and Microarray Analysis to Identi...
A significant proportion of acute myocardial infarction (MI) patients develop heart failure (HF). Early identification of patients at risk of developing HF after MI would be a major breakthrough. An approach combining the power of biological information networks and the precision of microarray analysis was undertaken to identify biomarkers of HF. A set of three new biomarkers of HF was identified and provided significantly improved prediction accuracy than microarray or network analysis alone...

Microarray predictor of response to infliximab in rh...
We sought to find a gene-expression multigene predictor of response to infliximab therapy in Rheumatoid Arthritis patients. Using internal and external cross-validation systems we have built and validated an 8-gene predictor for response to infliximab.

Early and long-standing rheumatoid arthritis: molecu...
At a given time, rheumatoid arthritis (RA) is a heterogeneous disease and its underlying molecular mechanisms is still poorly understood. Because previous microarrays studies have only focused on late RA stages, we aimed to compare the biological and molecular profiles in early and long-standing (LS) RA. Synovial biopsies obtained by arthroscopy were performed in 4 early untreated RA patients, 4 LS treated RA patients and 7 control patients. Extracted mRNA were linearly amplified and used fo...

Activation of mTOR controls the loss of TCRζ in lupu...
CD3-positive T cells were negatively isolated from 10 SLE patients and 9 healthy controls without SLE. All of the SLE samples and control samples were compared with one another to identify baseline differences in expression due to the disease. Next, T cell preparations from 4 of the control subjects were stimulated with either Nitric Oxide (NOC-18) 600 uM for 24hr or stimulated through CD3/CD28 for 24hr to determine which genes were responsive to these signaling mechanisms. Here, we show th...

Interactions of cytokines in peripheral blood cells ...
SLE patients are always with various disease manifestation. Various cytokines are pointed interacting and playing pathological roles in SLE although the etiopathology is still obscure. In this study, we aimed to investigate the effects of cytokine interactions in the immune response of SLE patients. Overexpressed interferon-inducible(IFI) genes were confirmed in peripheral blood from SLE patients. Using network-based analysis on the immune response-related genes, several networks including cy...
