Outline of Final Research Achievements |
This study found novel mouse genes (e.g. Kzpi encoding KRAB zinc-finger and Zfpi encoding SCAN-zinc finger) exclusively and zygotically expressed in preimplantation embryos and ES cells. Kzpi-deficient mice showed smaller litter sizes. Interestingly, most imprinted genes were down regulated and the methylation levels of differentially methylated regions (DMRs) were decreased in homozygous ES cells. Kzpi was thus suggested to maintain DMRs against genome-wide demethylation in preimplantation embryos. However, transgenerational phenotypic attenuation of Kzpi-deficient mice was observed: normal methylation patterns of DMRs in Kzpi-deficient blastocyst and ES cells. Zfpi-deficient mice did not show any phenotype, but karyotype analysis revealed chromosomal gaps. Kzpi-deficient ES cells generated a teratoma composed of all the three-germ layer, but gave rise to embryonal carcinoma.
