[Impact of PAHs on the expression of PRDX in earthworm (Eisenia fetida)].

A peroxiredoxin6 (PRDX6)-like gene segment has been found in up-regulated cDNA libraries of earthworm Eisenia fetida exposed to benzo[a]pyrene(BaP). Analysis with basic local alignment search tool (BLAST) and phylogenetic analysis revealed that the gene segment contains a characteristic motif which was encoded by Cys, illustrating that this gene segment belongs to PRDX. To verify the response of PRDX in E.
