| Summary: | (PAHS) associated with crude oil induce CYPIAI gene a contaminant gradient. Interestingly, the CYPIAI MRNA data and EROD activity were detected in all species, though the and ethoxyresorufin-0-deethylase (EROD) activity (a CYPIAI at the study sites. All three assays were sensitive bands did not correlate with EROD activity in the same fish biomarker of exposure to PAHs in aquatic and marine differences between the near and far stations as expected for environments. Several benthic marine fish and invertebrates exhibited some inter- and intraspecies differences, expression, and this response has been utilized as a extracts in rat hepatoma H-4-IIE cells. CYPIAI MRNA levels hepatoma H-4-IIE cells also indicated low PAH contamination Higher molecular weight Polycyclic aromatic hydrocarbons indicators of PAH contamination. Invertebrate exposure to PAHs was estimated by determining MRNA levels using a CDNA probe derived from rainbow trout, or "far", >3000 m). Hepatic tissues were analyzed for CYPIAI PAH contamination at these sites. Intensities of the MRNA platforms in the northwest Gulf of Mexico and subdivided with relative response intensities were low, indicating minimal respect to distance from the platforms (i.e. "near", <100 m response) was also determined in the fish species. species. Bioanalysis of invertebrate extracts in rat species. The results indicated that there were no consistent suggesting genetic differences in this gene in various fish the dose-dependent induction of EROD activity by invertebrate were collected in the vicinity of offshore petroleum |
