As indicators of responsiveness to a tumour necrosis factor (TNF)alpha blocking agent (infliximab) are lacking in rheumatoid arthritis, we have used gene profiling in peripheral blood mononuclear cells to predict a good versus poor response to infliximab. Thirty three patients with very active disease (Disease Activity Score 28 >5.1) that resisted weekly(More)
Activation of the complement system generates the anaphylatoxin C5a whose activities are mediated through its binding to the widely expressed C5aR. C5aR mRNA and protein expressions are known to be induced in rat hepatocytes under inflammatory conditions. However, little is known about the role of the C5a/C5aR complex in liver and its involvement during a(More)
INTRODUCTION Rheumatoid arthritis (RA) is a heterogeneous disease and its underlying molecular mechanisms are still poorly understood. Because previous microarray studies have only focused on long-standing (LS) RA compared to osteoarthritis, we aimed to compare the molecular profiles of early and LS RA versus control synovia. METHODS Synovial biopsies(More)
Cirrhotic liver is considered to regenerate less actively than normal liver after hepatic resection. However, the mechanisms responsible for this impaired regeneration and the cross talk of implicated factors still remain unclear. In the present study, mRNA levels for cyclins, growth factors, and cytokines were quantitatively assessed by a RT-PCR method at(More)
BACKGROUND B and T cells play a key role in rheumatoid arthritis (RA) pathophysiology. RasGRP1 and RasGRP3 are involved in T and B cell receptors signaling, and belong to gene combination able to predict infliximab responsiveness, leading to the question of RasGRP1 and RasGRP3 involvement in RA. METHODS RasGRP1 and RasGRP3 expression levels were measured(More)
Daveau. Changes in growth factor and cytokine mRNA levels after hepatectomy in rat with CCl 4-induced cirrhosis. Am.—Cirrhotic liver is considered to regenerate less actively than normal liver after hepatic resection. However, the mechanisms responsible for this impaired regeneration and the cross talk of implicated factors still remain unclear. In the(More)
