GSE84922: SALL4 ensures oocytes maturation by modulating DNA methylation and histone modifications (RNA-Seq)

  • Organsim mouse
  • Type RNASEQ
  • Target gene
  • Project ARCHS4

Splat-like 4 (Sall4) plays important roles in maintaining pluripotency of embryonic stem cells and in various developmental processes. Here, we find that the SALL4 null oocytes fail to undergo maturation to form fully-grown oocytes (FGOs) and subsequent meiosis resumption. We further discover that the loss of maternal SALL4 causes failure in establishment of DNA methylation. Moreover, we demonstrate that SALL4 modulates H3K4me3 and H3K27me3 modifications by regulating the expression of Kdm5b, Kdm6a and Kdm6b. Taken together, SALL4 plays pivotal roles in oocyte epigenetic maturation. SOURCE: Shaorong Gao (gaoshaorong@tongji.edu.cn) - Tongji University
