Assessing cell line models for species differences in 6PPD-quinone sensitivity

Coho salmon have been shown to be highly sensitive to the tire transformation chemical 6PPD-quinone, with concentrations contained in stormwater sufficient to induce mortality in up to 90% of the entire fall coho run. Other salmonid species (chinook, sockeye, chum) are much less sensitive to 6PPD-quinone induced mortality. This data examines the varying species sensitivities across salmoids using in vivo exposures in juvenile fish. We then used established cell lines forom these species to assess their suitability for in vitro studies concerning species differences in toxicokinetics using fluorescence and absorbance-based plate assays.
