| Research Abstract |
The purpose of this study is to develop the animal model whose fertility can be controlled through modification of implantation-associated genes. We have been trying to employ two different approaches: 1) introduction of DNA or viral vectors harboring the gene of interest into the uterine cavity, 2) generation of genetically engineered mice whose implantation-related genes can be modulated spatially and temporally. Firstly, we have cloned calcium binding protein D-9K (Cabp9K) gene, which has been implicated in mouse embryo implantation, and generated its mammalian expression vectors as well as antisense oligonucleotides (AS-ODN) against Cabp9K. We also have been trying to establish the optimal condition of introducing the plasmid vectors into the mouse uterine cavity using reporter vectors harboring lacZ or GFP gene. Besides the development of the gene delivery system, we have successfully generated transgenic mice in which the expression of Cre recombinase can be spatially and temporally regulated in the uterus. To evaluate conditional DNA deletion, crossing the transgenic mice with the cActXstopXLacZ reporter mice is now underway.
