Description
Analysis of gene expression profile in peritoneal macrophage extracted from LPS or PBS challenged DUSP3-/- and WT mice. DUSP3 deletion protects mice from sepsis and endotoxemia. We performed a microarray analysis to get insights into the differentially regulated pathways between WT and KO under inflammatory conditions.

Description
Rheumatoid arthritis (RA) is an inflammatory joint disorder that results in progressive joint damage when insufficiently treated. In order to prevent joint destruction and functional disability in RA, early diagnosis and initiation of appropriate treatment with Disease-Modifying Antirheumatic Drugs (DMARDs) is needed. However, in daily clinical practice, patients may initially display symptoms of arthritis that do not fulfil the classification criteria for a definite diagnosis of RA, or any other joint disease, a situation called Undifferentiated Arthritis (UA). Out of the patients with UA, 30 to 50% usually develop RA, and early identification of these remains a challenge.

Description
Objective: Rituximab displays therapeutic benefits in the treatment of rheumatoid arthritis (RA) patients resistant to TNF blockade. However, the precise role of B cells in the pathogenesis of RA is still unknown. In this study we investigated the global molecular effects of rituximab in synovial biopsies obtained from anti-TNF resistant RA patients before and after administration of the drug.
Publication Title
Rituximab treatment induces the expression of genes involved in healing processes in the rheumatoid arthritis synovium.

Description
TNF antagonists are routinely used in severe rheumatoid arthritis (RA) patients who failed conventional DMARD therapy. According to large clinical trials, the three available drugs (adalimumab, infliximab and etanercept) display similar effects in terms of efficacy, tolerability and side effects. These studies also indicate that about 25% of RA patients treated with TNF-antagonists do not display any significant clinical improvement.
Publication Title
Gene expression profiling in the synovium identifies a predictive signature of absence of response to adalimumab therapy in rheumatoid arthritis.

Description
TNFalpha and IL1beta play a pathogenic role in rheumatoid arthritis. Both cytokines are known to activate cytokine and metalloproteinase secretion by synovial fibroblasts. In the present study, we wanted to investigate whether TNFalpha and IL1beta displayed differential effects on cultured Fibroblast-like Synovial Cells derived from RA patients. Global gene expression analyses indicated that both cytokines induced similar genes in these cells.

Description
The role of stem cells in solid tumors remains controversial. In colorectal cancers (CRC), this is complicated by the conflicting top-down or bottom-up hypothesis of cancer initiation. We profiled the expressions of genes from the top (T) and bottom (B) fractions of the crypt in morphologically normal-appearing colonic mucosa (M) and contrasted this to that of matched mucosa adjacent to tumors (MT) in twenty three sporadic CRC patients. In thirteen patients, the genetic distance (M-MT) between the B fractions is smaller than the distance between the T fractions indicating that the expressions of significant genes diverge further in the top fractions (B<T). In the remaining ten patients, the reverse is observed (B>T).
Publication Title
Human colorectal cancer initiation is bidirectional, and cell growth, metabolic genes and transporter genes are early drivers of tumorigenesis.
