Protein synthesis costs could account for the tissue-specific effect of sub-lethal copper on protein synthesis in rainbow trout (Oncorhynchus mykiss)
This study investigates protein synthesis and sub-lethal Cu exposure in vivo and in vitro. In vivo only skin protein synthesis was reduced. Although this is a relatively sensing biomarker, the gills and liver were unaffected. Reductions in skin protein synthesis in vitro incurred increased synthesis costs whereas hepatocyte and gill cell protein synthesis costs were marginally affected. We hypothesise the energetic demand of protein synthesis determines tissue sensitivity Since much greater Cu concentrations were required to effect protein synthesis in vitro we also suggest the main use for cell cultures is in understanding toxicity mechanisms rather than for environmental monitoring.
