Final Report Abstract
The data generated in this collaborative project demonstrate that RNA storage and stability, poly(A) tail dynamics, histone methylation patterns and embryonic genome activation are not (exclusively) timed by ovulation or fertilization, but, at least partly, regulated by events in the growing or maturing oocyte. A delay in ovulation or fertilization desynchronizes oocyte development and fertilization, which may consequently affect the embryonic programs with potentially long-lasting effects.
