This invention provides methods for reducing the amount of Dnmt3L in a cell, obtaining a cell having a reduced amount of Dnmt3L, and cells, tissues, organs and non-human transgenic mammals having a reduced amount of Dnmt3L. This invention further provides related methods for producing a mammalian zygote in vitro which, upon successful subsequent development in utero, gives rise to a mammal having a reduced susceptibility to an abnormality associated with epigenetic instability. This invention further provides methods for determining the amount of Dnmt3L in a cell, and methods for determining whether agents bind to Dnmt3L or decrease the amount of Dnmt3L in a cell. Finally, this invention provides related nucleic acids and compositions. |
