FOXH1 Is Regulated by NANOG and LIN28 for Early-stage Reprogramming.

ABSTRACT: FOXH1 is a primitive-streak specifier and ACTIVIN co-effector that plays an important role in development, and positively regulates the generation of human induced pluripotent stem cells (iPSCs) from somatic cells by OCT4, SOX2, KLF4, and MYC (OSKM) transduction. However, the mechanism and upstream regulation for FOXH1 expression in reprogramming are unclear. We found FOXH1 expression plays a significant role to enhance epithelial marker and suppress mesenchymal gene expression in OSKM-mediated human cell reprogramming. Furthermore, NANOG and LIN28 (NL) co-stimulate FOXH1 expression, which correlates with the enhanced reprogramming efficiency by NL-factors. FOXH1 expression is also stimulated by a specific inhibitor for H3K79 methyltransferase DOT1L (iDOT1L) but not by inhibition of the ca
