Evaluation of transcriptional biomarkers using a high-resolution regression approach : Concentration-dependence of selected transcripts in copper-exposed freshwater mussels (Anodonta anatina)
We tested concentration-dependence of selected gene transcripts (cat, gst, hsp70, hsp90, mt and sod) for evaluation as biomarkers of chemical stress. Contrary to the common approach of factorial designs and few exposure concentrations, we used regression across a high-resolution concentration series. Specifically, freshwater mussels (Anodonta anatina) were acutely (96 h) exposed to Cu (13 nominal
