LIFE SCIENCES 2022; 65:1985-1997. [PMID: 35391627 DOI: 10.1007/s11427-021-2076-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Accepted: 01/21/2022] [Indexed: 06/14/2023]
Abstract
The pluripotent state of embryonic stem cells (ESCs) is regulated by a sophisticated network of transcription factors. High expression of KLF17 has recently been identified as a hallmark of naive state of human ESCs (hESCs). However, the functional role of KLF17 in naive state is not clear. Here, by employing various gain and loss-of-function approaches, we demonstrate that KLF17 is essential for the maintenance of naive state and promotes the primed to naive state transition in hESCs. Mechanistically, we identify MAPK3 and ZIC2 as two direct targets repressed by KLF17. Overexpression of MAPK3 or ZIC2 partially blocks KLF17 from promoting the naive pluripotency. Furthermore, we find that human and mouse homologs of KLF17 retain conserved functions in promoting naive pluripotency of both species. Finally, we show that Klf17 may be essential for early embryo development in mouse. These findings demonstrate the important and conserved function of KLF17 in promoting naive pluripotency and reveal two essential transcriptional targets of KLF17 that underlie its function.
