The present invention is based on the determination of the global changes in gene expression in tissues or cells exposed to known toxins, in particular hepatotoxins, as compared to unexposed tissues or cells as well as the identification of individual genes that are differentially expressed upon toxin exposure.
The invention includes methods of predicting at least one toxic effect of a compound, predicting the progression of a toxic effect of a compound, and predicting the hepatoxicity of a compound. Also provided are methods of predicting the mechanism of toxicity of a compound. In a further aspect, the invention provides probes comprising sequences that specifically hybridize to genes in Table 3 as well as solid supports comprising at least two of the said probes.
本发明的基础是确定暴露于已知毒素(特别是肝毒素)的组织或细胞与未暴露的组织或细胞相比基因表达的总体变化,以及鉴定暴露于毒素时表达不同的单个基因。
本发明包括预测化合物的至少一种毒性效应、预测化合物毒性效应的进展以及预测化合物肝毒性的方法。还提供了预测化合物毒性机制的方法。在另一个方面,本发明提供了包含与表 3 中的基因特异性杂交的序列的探针以及包含至少两种所述探针的固体支持物。
