Embryonic stem cells (ESCs) depend on extensive regulatory networks to coordinate their self-renewal and differentiation. The polyamine pathway regulator AMD1 was recently implicated in ESC self-renewal and directed differentiation of ESCs to neural precursor cells (NPCs). The polyamines spermine and spermidine are essential for a wide range of biological processes, and their levels are tightly regulated. Here, we review the polyamine pathway and discuss how it can impact polyamine levels, cellular methylation and hypusinated EIF5A levels. We discuss how it could feed into regulation of ESC self-renewal and directed differentiation. We show that in addition to AMD1, a second rate-limiting enzyme in the polyamine pathway, ODC1, can also promote ESC self-renewal, and that both Amd1 and Odc1 can partially substitute for Myc during cellular reprogramming. We propose that both Amd1 and Odc1 are essential regulators of ESCs and function to ensure high polyamine levels to promote ESC self-renewal. 相似文献
