METHODS: Transgene expression was analyzed with RT-PCR and Western blotting. For one of the transgenic mouse lines, tissue expression pattern of the transgene was also examined with immunochemical methods. Pathological analysis was used to examine the tissue morphologic phenotype of established transgenic mice. The liver gene expression profile of transgenic mice was analyzed with microchip, and some of bhe differentially expressed genes were verified with RT-PCR. RESULTS: The expressions of hBIF were shown in livers from 6 of 7 transgenic mouse lines. The overexpression of hB1F transgene did not cause pathological changes. Expressions of three genes were up-regulated, while down-regulation was observed for 25 genes. CONCLUSION: The overexpression of hBIF transgene may cause changes of gene expression profiles in the liver of transgenic mice.展开更多
