Abstract
Concentration and time-dependent changes in hepatic gene expression were examined in adult, female zebrafish (Danio rerio) exposed to 0, 0.1, 0.7, 4.9mug/L of a model androgen, 17alpha-methyldihydrotestosterone (MDHT). At 24 and 168h, fish were sacrificed and liver was extracted for gene expression analysis using custom Affymetrix GeneChip((R)) Zebrafish Genome Microarrays. In an effort to link gene expression changes to higher levels of biological organization, blood was collected for measurement of plasma steroid hormones (17beta-estradiol (E2), testosterone (T)) and vitellogenin (VTG) using ELISA. Body and ovary weight were also measured. A significant reduction in E2 occurred at 24h
