Project description:Methotrexate (MTX) is an anti-folate drug used to treat inflammatory diseases such as rheumatoid arthritis. The changes induced by MTX were profiled within EA.hy 926 cells grown in normal (Hi) and low (Lo) folate. Several inflammatory genes were up regulated and several mitosis related genes were down regulated.

Project description:Oligo microarrays were used to access the transcription profiling of the rheumatoid arthritis patients under two different therapeutic approaches, aiming to evaluate if the cDNA microarray study is able to differentiate responders and non-responders to therapies. In the first experiment (MTX therapy) we analyzed 25 patients from which 8 were classified as MTX responders and 17 MTX non-responders. In the second experiment from the 17 MTX non-responder patients, 8 were non-responders and 9 were responders to additional anti-TNF therapy.

The changes induced by MTX were profiled within EA.hy 926 cells grown in normal (Hi) and low (Lo) folate. Several inflammatory genes were up regulated and several mitosis related genes were down regulated. Hi and Lo cells were grown to confluence and maintained in fresh medium for 24 hours prior to treatment with 0.5uM MTX for 48 hours.

Project description:This microarray study was conducted along with SATORI study, the clinical trial evaluated 125 patients with active RA with an inadequate response to low dose of MTX. Patients were allocated to receive either Tocilizumab(TCZ) 8 mg/kg every 4 weeks (TCZ group) or MTX 8 mg/week (MTX/control group) for 24 weeks. Gene expression profiles (GEP) of 112 patients - 54 patients from TCZ group and 58 patients from MTX group - were obtained in this study.

Project description:A summary of the work associated to these microarrays is the following: The need for an integrated view of all data obtained from high-throughput technologies gave rise to network analyses. These are especially useful to rationalize phenomena in terms of how external perturbations propagate through the expression of genes. To address this issue in the case of drug resistance, we constructed Biological Association Networks of genes differentially expressed in cell lines resistant to methotrexate (MTX). Seven cell lines representative of different types of cancer including colon cancer (HT29 and Caco2), breast cancer (MCF7 and MDA-MB-468), pancreatic cancer (MIA PaCa-2), erythroblastic leukemia (K562) and osteosarcoma (Saos-2), were used. The differential expression pattern between sensitive and MTX-resistant cells was determined by microarrays covering the whole human genome and analyzed with the GeneSpring GX software package, v.7.3.1. Genes deregulated in common in the two colon cancer cell lines studied, were subject of Biological Association Networks construction. Dikkopf homolog-1 (DKK1) was a clear node of this network, and functional validations of this target using a siRNA showed a chemosensitization toward MTX. Members of the UDP-glucuronosyltransferase 1A (UGT1A) family formed a network of differentially expressed genes in the two breast cancer cell lines studied. siRNA treatment against UGT1A showed also an increase in MTX sensitivity. Eukaryotic translation elongation factor 1 alpha 1 (EEF1A1) was a gene overexpressed in common among the pancreatic cancer, leukemia and osteosarcoma cell lines, and siRNA treatment against EEF1A1 produced a chemosensitization toward MTX. Biological Association Networks identified DKK1, UGT1As and EEF1A1 as important gene nodes in MTX-resistance. Treatments using iRNA technology against these three genes show chemosensitization toward MTX.
