Cluster analysis of gene expression after DEN treatment. The expression of 50 genes was clustered by hierarchical clustering after DEN treatment. Results of 4 h and 28 days were analyzed separately. The color displays show the log2 (expression ratio) as (1) red when the treatment sample is up-regulated relative to the control (vehicle) sample, (2) blue when the treatment sample is down-regulated relative to the control sample and (3) white when the log2 (expression ratio) is close to zero.
