Transcriptional Profiles Induced by the Aryl Hydrocarbon Receptor Agonists 2,3,7,8-Tetrachlorodibenzo-p-dioxin, 2,3,7,8-Tetrachlorodibenzofuran and 2,3,4,7,8-Pentachlorodibenzofuran in Primary Rat Hepatocytes

Transcriptional profiling of primary rat hepatocytes exposed to high and low doses of three compounds, as well as untreated cells. All samples were co-hybridized with DMSO controls. A direct two-color experiment design, with each treated sample co-hybridized with a DMSO control. Hepatocytes derived from two animals were used as biological replicates. Four microarrays were completed for each chemical/dose combination. The four replicate arrays represent two dye-swapped microarrays for each of the two animals.
