Differential gene expression in anthracene-exposed mummichogs (Fundulus heteroclitus).

The polycyclic aromatic hydrocarbon (PAH) anthracene is present in many estuarine systems at concentrations believed to cause sublethal adverse effects, although its exact mode of toxicity remains unclear. Knowledge of the induction or suppression of specific genes as a result of exposure may be useful in explaining these effects. We have generated a fingerprint of anthracene exposure using the mummichog (Fundulus heteroclitus), a non-migratory estuarine fish species.
