Study Suggests Wider Range of Mahi-Mahi’s Genetic Responses to Oil Exposure
Scientists used novel bioinformatics to investigate molecular-level changes over time and toxicity pathways in mahi-mahi embryos and larvae exposed to Deepwater Horizon oil. They observed that weathered oil (collected from slick skimming operations) induced more pronounced gene expression changes than a non-weathered source oil (collected from the subsea containment system directly over the wellhead). The tools predicted impairment of heart rates and increased pericardial edema which the researchers observed in the fish. The method also predicted disturbances in eye and nervous system development. These results suggest new genetic and developmental toxicity pathways targets associated with Deepwater Horizon oil.
