Snai1 represses Nanog to promote embryonic stem cell differentiation.

ABSTRACT: 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 with the loss of pluripotency and ESC differentiation [9-11]. During ESC early differentiation, many development-associated genes become upregulated and although, in general, much is known about the pluripotency self-renewal circuitry, the molecular events that lead ESCs to exit from pluripotency and begin differentiation are largely unknown. Snai1 is one the most early induced genes during ESC differ
