Background
POU5F1 (Oct3/4, POU class 5 homeobox 1) belongs to POU homeobox transcription-factor family and sustains pluripotency and self-renewal of embryonic stem cells. As core pluripotency regulator, Oct3/4 cooperates with Sox2 and Nanog, binds Oct-Sox cis-elements to activate stem-ness programs and repress differentiation-associated genes. Its expression is restricted to early embryo, ESC and iPSC. Dosage of Oct3/4 delicately controls stem-cell fate; either elevation or reduction induces differentiation. It is nearly absent in most adult tissues but re-activated in cancer stem cells to sustain oncogenic stemness.
