Open TG-GATEs (in vivo repeat dosing)


ABSTRACT: The Toxicogenomics Project was a 5-year collaborative project (2002-2007) by a consortium comprising the Japanese government and several pharmaceutical companies. The project produced the 'Toxicogenomics Project-Genomics Assisted Toxicity Evaluation system' (TG-GATEs), a large-scale database of transcriptomics and pathology data potentially useful for predicting the toxicity of new chemical entities. Conventional in vivo toxicology data was collected from single dose and repeat dosing studies on rats, and gene expression measured for the liver (and kidney in some cases). To provide information on species differences, gene expression was also measured in rat and human hepatocytes treated with the chemicals in vitro. Approximately 130 chemicals, primarily medicinal compounds, were tested at multipe doses. Gene expression was analysed using Affymetrix GeneChip arrays. The gene expression data has been submitted in four parts: in vivo single dose (E-MTAB-799), in vivo repeat dosing, in vitro rat (E-MTAB-797) and in vitro human (E-MTAB-798). This submission comprises the in vivo, repeat dosing studies.

Please note that the European Bioinformatics Institute (EBI) was not involved in the Toxicogenomics Project in any way, acting only to submit the transcriptomics data to Array Express. Queries about the project can be addressed to the consortium directly via 'opentggates@nibio.go.jp'. This dataset is part of the TransQST collection.

One expected result from toxicogenomics technology is to overcome the barrier because of species-specific differences in prediction of clinical toxicity using animals. The present study serves as a model case to test if the well-known species-specific difference in the toxicity of coumarin could be elucidated using comprehensive gene expression data from rat in-vivo, rat in-vitro, and human in-vitro systems. Coumarin 150 mg/kg produced obvious pathological changes in the liver of rats after repe  ...[more]
