Expression profile of higly expressed genes demonstrates a distinct Au response in comparison to As^V and Cd^II. Thirty nine genes, selected on the basis of their expression cut off (>5-fold) under the conditions of Au and heavy metal exposures, demonstrate significant differences in expression patterns under the three conditions. The log(2)-ratio expression values for As^V and Cd^II downloaded from the known database using the Genevestigator were combined with the values from the present data and a heat map was prepared using an online plot tool. Please refer to the Materials and Methods for more information.
