ORGANISM(S): Homo sapiens 
The experiment was aimed at identification of genes whose expression is upregulated in human colon cancer C85 cells during the process of establishment of methotrexate-induced senescence.

We investigated the influence of genome position on propensity to amplify. First, we integrated a mutant form of DHFR into different positions in the human genome, challenged cells with methotrexate and then studied the genomic alterations arising in drug resistant cells. We observed site specific d...

Methotrexate (MTX) serves as the primary treatment for rheumatoid arthritis (RA), though its mechanism of action is not yet fully understood. The goal of this study was to map the cellular and molecular changes triggered by MTX across different points in time. Using a prospective longitudinal design...

cea06-02_folate - methotrexate treatment - global analysis of the folate metabolism in Arabidopsis - Treatment of cells of Arabidopsis by methotrexate which is an inhibitor of the synthesis of the folate. Consequently, the pool of folates presents a strong reduction. The goal of this project is to l...

This SuperSeries is composed of the following subset Series: GSE9947: Transcriptional analysis of Leishmania infantum methotrexate resistant strains using full-genome DNA microarrays GSE9948: Transcriptional analysis of Leishmania major methotrexate resistant strains using full-genome DNA microarray...
ORGANISM(S): Leishmania infantum 
Comparison of transcript abundance between control (untreated) and methotrexate treated S3 Drosophila cells and ovaries disected from female flies. S3 cells were exposed to 0 or 5.2 X 10^-8 M MTX for 4 days then harvested. Flies were exposed to 0 or 5 ppm MTX for 5 days then ovaries were dissected....

This SuperSeries is composed of the following subset Series:; GSE11440: Role of Caveolin 1, E-Cadherin, Enolase 2 and PKCa on resistance to methotrexate in human HT29 colon cancer cells; GSE16066: Networking of differentially expressed genes in CaCo2 human colon cancer cells resistant to methotrexat...

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...
