Sood; Mechanism of the anti-inflammatory effect of anti inflammatory in rheumatic diseases: Colchicine is an alkaloid that is used to alleviate acute gout and to prevent acute attacks of familial Mediterranean fever FMF. However, it is not beneficial when given during the occurrence of an acute episode of FMF.

Treatment of Gout

It is believed that colchicine exerts its anti-inflammatory effect through direct interaction with microtubules. We aim to study the molecular basis of colchicine action by not nsaid the effect of this drug on global gene expression of HUVEC human umbilical vein endothelial cell line cells.

HUVEC cells were exposed to various concentrations of colchicine and were harvested at different time points. Ribonucleic acid was extracted, amplified, reverse transcribed and hybridized to complementary deoxyribonucleic acid microarrrays containing more than 40, probes to human expressed sequence tags.

This approach enabled us to have a global look at the transcriptional response induced by colchicine treatment. The anti-inflammatory effect of colchicine may be mediated not only through direct interaction with microtubules but also through changes at the transcriptional level.

This latter effect apparently requires a is colchicine an anti inflammatory that is not nsaid concentration and a longer time to occur. This can explain the observation that colchicine does not have an immediate effect when given during an acute attack of FMF. Colchicine is an alkaloid that has been used for centuries in acute is colchicine an anti inflammatory that is not nsaid arthritis. In acute gout, colchicine is effective in alleviating not nsaid acute attack and as a prophylactic medication.

In scleroderma, it may decrease is colchicine an anti inflammatory that is not nsaid stiffness of the skin, whereas in amyloidosis it may improve proteinuria and result in regression /discontinuing-wellbutrin-xl-user-reviews.html amyloid deposition in cases where these fibres are deposited [ 3 ].

Perhaps the most effective results of colchicine treatment have been obtained in the prophylaxis is colchicine an anti inflammatory that is not nsaid FMF [ 4 ].

In this disease, it prevents the occurrence of the acute inflammatory episodes inflammatory that fends off the development of amyloidosis. However, it is not effective in controlling acute attacks when administered while they occur. Colchicine consists of three hexameric rings termed A, B and C. The tropolone methyl ester, which is a precise analogue of the ring Colchicine of colchicine, not nsaid bind the tubulin molecule thereby inhibiting its polymerization into microtubules in vitro [ anti ].

Since microtubules are part of the cytoskeleton in almost every eukaryotic cell, the effect of colchicine at the cellular level is generally assumed to stem from its direct interaction with microtubules.

Specifically, its anti-inflammatory effect has been attributed to its disruption of microtubules in neutrophils, thereby inhibiting their migration toward the chemotactic factors. Colchicine, Cronstein et al. Thus, there is growing evidence see more the anti-inflammatory effect of colchicine is multifaceted. In the present study we tried to better understand the molecular basis of the action of colchicine by analysing the effect of this drug on global gene expression.

We exposed HUVEC human umbilical vein endothelial cell line cells to different concentrations of colchicine and examined their is colchicine an anti inflammatory that is not nsaid response using colchicine deoxyribonucleic acid cDNA microarrays. This approach enabled us to take a global view of the transcriptional response induced by colchicine treatment and allowed for click the following article identification of sets of genes that are potentially related to its mechanism of action, beyond its direct interaction with microtubules.

The please click for source were taken at least anti inflammatory days after their last split before exposure to colchicine. They were exposed to three concentrations of colchicine: Controls of Article source cells, using the is colchicine colchicine anti inflammatory that is not nsaid conditions not nsaid time points but without exposure to colchicine, were obtained and processed similarly.

Three replicates were included for the zero time point with no colchicine and duplicates for most colchicine concentrations and time is colchicine an anti inflammatory that is not nsaid.

The microarrays we used comprised 42, elements 42K representing 32, unique Unigene clusters build noreleased 18 January and 11, known genes unique Unigene symbols.

Fluorescent dyes were purchased from Amersham Pharmacia Biotech. Hybridizations were carried out using the standard protocol described previously [ 1012 ]. Experimental inflammatory that can be found at http: Data were analysed using GenePix 5.

Spots /nexium-40-mg-uses-que-serve.html aberrant measurements due to array artefacts or poor quality were manually or automatically flagged and removed from further analysis. For further analysis we retrieved the log 2 ratios of the background-corrected anti, i. We only included genes whose expression varied significantly is colchicine an anti inflammatory that is not nsaid the dataset. Specifically, in at least three samples the expression levels of a gene had to differ more than 3-fold from the mean expression level of all samples.

Hierarchical clustering was applied to the genes and arrays, using the Pearson correlation coefficient as a measure of similarity and average linkage clustering as described previously [ 10121415 ]. Results were visualized using Eisen's TreeView [ 14 ] and custom-made software written in Matlab http: The entire dataset and the results of our analysis are available at our web site at http: Here is a link approach to the identification of genes whose expression patterns are significantly associated with specific characteristics of the samples [ 16 ].

We applied SAM to our dataset in order to identify differential expression patterns between different types of samples. We identified gene ontology GO terms enriched with genes is colchicine an anti inflammatory that is not nsaid expression changed significantly under exposure to colchicine.
