DNA array technology was applied to detect the interactions between environmental chemicals and the cultured human neuroblastoma NB-1 cells. Some environmental chemicals such as cadmium and bisphenol A facilitated the neurite of the cells, others collapsed them. The neurite of the neural cells were unchanged by the exposure to dioxin. However, the levels of the gene expression were changeable by the exposure to not only cadmium and methylmercury but also to dioxin.
Thus, DNA array technology is a powerful mean to analyze the interactions between environmental factors and health.
