Although cadmium causes hepatotoxicity, its molecular mechanism is unclear. In the present study, transcriptional responses in the liver of C57BL/6J mice given 50 ppm cadmium as a drinking water for 30 days were evaluated with DNA microarray. Serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activities were not elevated following the administration of cadmium. Cadmium increased the expressions of 2 genes and reduced those of 15 genes in the liver of mice before the leading to hepatotoxicity.
