Abstract

The aim of this study is to establish transgenic mice that specifically over-express human APE1 incardiac, and to provide a tool animal for studying the relationship between the function and mutation of hAPE1 gene and cardiac development and cardiovascular diseases. A cardiomyocyte-specific hAPE1 transgenic construct containing the α-myosin heavy chain (α-MHC) promoter and human A PE1 (hA PE1) gene was generated. The transgenic vector was constructed by insertion of hAPE1 gene under the α-MHC promoter. The transgenic mice were generated by fertilized egg microinjection followed by embryo transplantation and were all maintained on C57BL/6J genetic background. The genotype of transgenic mice was identified using PCR and the expression levels of hAPE1 in different tissues were detected by Western blotting. The results indicated that cardiomyocyte-specific hAPE1 transgenic construct containing the α-myosin heavy chain (α-MHC) promoter and human APE1 (hAPE1) gene were introduced into fertilized zygotes by microinjection, and then the fertilized zygotes were implanted into the oviduct of female mice, establishing a heart specific high expression hAPE1 transgenic mouse line. 40 offspring were obtained and 15 mice carrying the human APE1 gene was identified by PCR. The heart-specific overexpression of hAPE1 was confirmed by Western blotting assay. The present study successfully obtained cardiomyocyte-specific hAPE1 transgenic mice transgenic mice expressing, which provided a useful tool for studying the function of genes in heart development and cardiovascular disease.
