To screen environmental response genes related to dental fluorosis, and to provide clues for further researches of the molecular mechanism of fluorosis. The leukocyte gene expression profiles of control group, high-loaded fluoride group and dental fluorosis group were tested using the gene chiR HG-U133A from Affymetrix company. The results were analyzed by bioinformatical methods. Compared with control group, a total of 1057 genes were differentially expressed in high-loaded fluoride group. Of

A total of 964 genes were differentially expressed in dental fluorosis group as compared with control group, including 71 robustly up-regulated genes and 60 robustly down-regulated genes. Compared with high-loaded fluoride group, 633 genes were identified to be differentially expressed in dental fluorosis group. Of these, the number of robustly up-regulated genes and robustly down-regulated genes were respectively 15 and 67. Multiple genes are related to fluorosis.
