Suppression subtractive hybridization complementary DNA libraries identified differentially expressed genes in liver tissue of winter flounder collected from the highly impacted Raritan-Hudson estuary versus those from less industrialized estuaries farther south in New Jersey. Distinct transcript profiles emerged in the fish from these different habitats. A total of 251 clones from the forward (upregulated with anthropogenic impact) and reverse (downregulated with anthropogenic impact) subtracted libraries were sequenced. In the upregulated library immune response transcripts, including complement C-3, C-7, factor H, factor Bf/C2, differentially regulated trout protein 1, and the antimicrobial hepcidin, indicated the pollution-impacted fish were under a high viral or bacterial load. Transcripts for cytochrome P450 1A, P450 3A, and glutathione S-transferase, important components of phase I and II metabolism of xenobiotics, were found in the upregulated-with-pollution library. Vitellogenins I and II and egg envelope protein (zp) appeared to be downregulated. A homologue of the tumor suppressor p33(ING1) (down) and hepatocyte growth factor-like protein (up) may indicate liver damage or hepatocellular carcinoma or hepatoma. These expression patterns, confirmed by quantitative polymerase chain reaction, indicate that transcript analysis is a useful method for assessing the health of local habitats and the organisms therein.
