Sall1 Regulates Embryonic Stem Cell Differentiation in Association with Nanog*
Sall1 is a multi-zinc finger transcription factor that regulates kidney organogenesis. It is considered to be a transcriptional repressor, preferentially localized on heterochromatin. Mutations or deletions of the human SALL1 gene are associated with the Townes-Brocks syndrome. Despite its high expression, no function was yet assigned for Sall1 in embryonic stem (ES) cells. In the present study...
متن کاملComparing the Expression Levels of Alkaline Phosphatase, Gfra1, Lin28, and Sall4 Genes in Embryonic Stem Cells, Spermatogonial Stem Cells, and Embryonic Stem-Like Cells in Mice
Background and purpose: Spermatogenesis is a well-organized process that is influenced by a variety of factors. Alkaline phosphatase, and Gfra1, Lin28, and Sall4 genes are among the key players in this interconnected process. This study aimed to investigate the expression levels of Gfra1, Lin28, and Sall4 genes in embryonic, spermatogonial, and embryonic stem-like (ES-like) cells in mice. Mate...
متن کاملNanog A New Recruit to the Embryonic Stem Cell Orchestra
In this issue of Cell, and add a new transcriptional operating system to the known Oct4 and Stat3 systems required for early embryonal stem cell potency and self-renewal. Nanog, a homeobox transcription factor, plays a crucial role in the second embryonic cell fate specification following formation of the blastocyst.
متن کاملSnai1 represses Nanog to promote embryonic stem cell differentiation
Embryonic stem cell (ESC) self-renewal and pluripotency is maintained by an external signaling pathways and intrinsic regulatory networks involving ESC-specific transcriptional complexes (mainly formed by OCT3/4, Sox2 and Nanog proteins), the Polycomb repressive complex 2 (PRC2) and DNA methylation [1-8]. Among these, Nanog represents the more ESC specific factor and its repression correlates w...
متن کاملDax1 and Nanog act in parallel to stabilize mouse embryonic stem cells and induced pluripotency
Nanog expression is heterogeneous and dynamic in embryonic stem cells (ESCs). However, the mechanism for stabilizing pluripotency during the transitions between Nanog(high) and Nanog(low) states is not well understood. Here we report that Dax1 acts in parallel with Nanog to regulate mouse ESC (mESCs) identity. Dax1 stable knockdown mESCs are predisposed towards differentiation but do not lose p...
