Application of Microarray Technique in Toxicology / 环境与健康杂志

ABSTRACT

Toxicogenomics is a new undertaking in the pursuit of human genomics relevant to health risk from environmental toxicants and related stress, and also is a new scientific subdiscipline derived from a combination of the fields of toxicology and genomics. Microarray technique, i. e. gene-chip technique includes gene-chip development, pretreatment of detected samples, probe hybridization, detection data analysis. The microarray technique in toxicology mainly was applied to identification of potential hazardous substances, screening for mechanism of action, dose-response relationship assessment, identification of interaction among chemical mixtures, biomarker of exposure and biomarker of susceptibility. Microarray technique has been used to study biomarker for human bladder cancer, to study fingerprints of gene regulation associated with cadmium chloride, benzo(a) pyrene and trichloroethylene. fn this paper, a new automated and multi-applied molecular biology workstation, NanoChip biomolecular system was introduced .
