Project description:Zfp281 is a partner protein of Nanog. To identify potential target genes of Zfp281, we generated Zfp281 null ESCs using gene targeting, and compared transcriptomic changes between multiple lines of wildtype, heterozygous and null ESCs. Total 8 ESC lines: 3 wildtype lines, 2 heterozygous lines, and 3 null lines.

Project description:Pluripotent cell identity comprises a spectrum of cell states including naive and primed states, which are typified by mouse embryonic stem cells (ESCs) and epiblast-derived stem cells (EpiSCs), respectively. Here we define a pluripotent cell fate (PCF) gene signature based on RNA-seq analysis associated with naive and primed pluripotency acquisition, and identify Zfp281 as a key transcriptional regulator for primed pluripotency and also as a barrier to achieve the naive pluripotency of both mouse and human ESCs. RNA sequencing analysis was performed in WT and Zfp281 null mouse embryonic stem cells under different pluripotent culture conditions. RNA-seq Experiments were carry out in two biological replciates. Genome binding/occupancy profiling of Zfp281 was performed in mouse embryonic stem cells by ChIP sequencing.

Project description:Embryonic stem cells (ESCs) derived from preimplantation blastocysts have unique self-renewal and multilineage differentiation properties that are controlled by key components of a core regulatory network including Oct4, Sox2, and Nanog. Understanding molecular underpinnings of these properties requires identification and characterization of additional factors that act in conjunction with these key factors in ESCs. We have previously identified Zfp281, a Krüppel-like zinc finger transcription factor, as an interaction partner of Nanog. We now present detailed functional analyses of Zfp281 using a genetically ablated null allele in mouse ESCs. Our data show that while Zfp281 is dispensable for establishment and maintenance of ESCs, it is required for their proper differentiation in vitro. We performed microarray profiling in combination with previously published datasets of Zfp281 global target gene occupancy and found that Zfp281 mainly functions as a repressor to restrict expression of many stem cell pluripotency genes. In particular, we demonstrated that deletion of Zfp281 resulted in upregulation of Nanog at both the transcript and protein levels with concomitant compromised differentiation of ESCs during embryoid body culture. Chromatin immunoprecipitation experiments demonstrated that Zfp281 is required for Nanog binding to its own promoter, suggesting that Nanog-associated repressive complex(es) involving Zfp281 may fine-tune Nanog expression for pluripotency of ESCs.

Project description:Cell-fate decisions and lineage commitment in early embryonic development are governed by comprehensive gene-regulatory programs. However, the molecular details leading to initial segregation of different lineages remain unclear. In the second cell-fate decision, epiblast (EPI) and primitive endoderm (PrE) lineages are formed from the pluripotent inner cell mass (ICM) cells at blastocyst stage. Here, we demonstrated that the pluripotency transcription factor Zfp281 is a barrier in embryonic stem cells (ESCs) to PrE lineage differentiation. Zfp281 is expressed in extraembryonic endoderm cells (XENs), the ex vivo derivatives of PrE. But knockdown of Zfp281 doesn’t affect either maintenance or expression of the PrE master regulators in XENs. Using an in vitro differentiation protocol, we revealed that knockout of Zfp281 significantly increased the efficiency of ESC to XEN derivation. Using a Zfp281 rescue line for the knockout cells, we further confirmed that effects of elevated efficiency of XEN derivation is specifically due to loss of Zfp281. Mechanistically, we revealed that Zfp281 interacts with components in the polycomb repressive complex 2 (PRC2), and recruits PRC2 to promoters of PrE master regulators GATA4 and GATA6 for transcriptional and epigenetic repression. Taken together, our results demonstrated a novel role of Zfp281 in second cell-fate decision in embryonic stem cell differentiation.

Project description:How CD4+ lineage gene expression is initiated in differentiating thymocytes remains poorly understood. Here, we show that the paralog transcription factors Zfp281 and Zfp148 control both this process and cytokine expression by T helper cell type 2 (TH2) effector cells. Genetic, single-cell, and spatial transcriptomic analyses showed that these factors promote the intrathymic CD4+ T cell differentiation of class II major histocompatibility complex (MHC II)–restricted thymocytes, including expression of the CD4+ lineage–committing factor Thpok. In peripheral T cells, Zfp281 and Zfp148 promoted chromatin opening at and expression of TH2 cytokine genes but not of the TH2 lineage–determining transcription factor Gata3. We found that Zfp281 interacts with Gata3 and is recruited to Gata3 genomic binding sites at loci encoding Thpok and TH2 cytokines. Thus, Zfp148 and Zfp281 collaborate with Gata3 to promote CD4+ T cell development and TH2 cell responses. This SuperSeries is composed of the SubSeries listed below.
