[The establishment and identification of GPx-1(P198L) gene systemic expression transgenic mice].

Objective: To generate systemic expression human cellular glutathione peroxidase-1 (GPx-1) (198Leu) transgenic mice model in order to investigate the functional variants in GPx-1 gene in oxidative stress-related diseases.
Methods: After linearization with BamnH I and Acc I, the transgenic construct GPx-1 (198Leu) was microinjected into the zygotes of C57BL/6J mice to generate transgenic mice, whose genotype was detected by PCR with specific primers. The GPx-1 gene expression profile was determined by Western blotting.
Results: 13 transgenic founder mice were successfully generated. Western blotting result showed that the protein expression level of 4 transgenic mice in hearts were higher than that of wild type mice.
Conclusion: Human GPx-1PSL transgenic mice was successfully established. This kind of animal model is of significance for making further researches on oxidative stress-related diseases.
