Groups of differentially regulated 431 genes with known functional class, which are categorized by their transcription directions upon 20 and 60 min exposures. Group I contained 23 genes upregulated upon both exposure times, while group II had 80 genes upregulated at 20 min and no significant changes upon 60 min exposure. Further, group III possessed 26 genes that were upregulated in response to 60 min exposure. Group IV contained 128 genes downregulated upon both exposure times, whereas 95 genes of group V exhibited downregulation after 20 min exposure. Finally, group VI had 79 genes that were downregulated upon 60 min exposure.
