Expression of Circadian Perl and Per2 Genes in the Liver and Breast Tumor Tissues of HER2eu Transgenic Mice of Different Age

摘要

The expression of Per1, Per2, and Cry1 circadian genes in the liver and breast tumors were studied by real-time PCR in FVB/N mice of different age transfected with HER-2eu gene. The expression of Per1 and Per2 genes in breast tumor tissue decreased in comparison with their expression in the lever. The expression of these genes decreased with age in both the liver and tumor tissue.
