RNA-Seq profiling of Sirt1 deficient mouse oocytes to investigate Sirt1 role in maternal-zygotic transition

Sirtuin-1 (Sirt1), a NAD+-dependent histone deacetylase, exhibits several properties of a versatile driver of maternal-zygotic transition, due to its epigenetic and non-epigenetic substrates. The study was aimed at the dynamics of Sirt1 in early embryos and the contribution to maternal-zygotic transition. A conditional Sirt1-deficient knock-out mouse model was used. Females were hormonally stimulated and used as oocyte donors. oocytes were parthenogenetically activated and Sirt1-/- two-cell embryos were used for transcriptomic analysis.
