Hierarchical cluster analysis of samples grouped into the 4 control and 4 treatment groups. A. Cluster analysis of all genes present on the chip. B. Heat maps represent select genes (statistically differentially expressing, Table-1) from signal transduction, redox balance, oxidative stress and xenobotic metabolism processes. Red bars represent high expression levels, blue represent low expression levels and yellow bars are similar to the normalized median gene expression values.
