USP7 represses lineage differentiation genes of mouse embryonic stem cells through both catalytic and non-catalytic activity [CUT&Tag]

ABSTRACT: USP7, a ubiquitin-specific peptidase (USP), plays an important role in many cellular processes through its catalytic deubiquitination of various substrates. However, its nuclear function to regulate gene expression in mouse embryonic stem cells (mESCs) remains largely unknown. Here, we report that USP7 maintains mESCs identity through both catalytic activity-dependent and -independent repression of lineage differentiation genes. Usp7 depletion attenuates SOX2 level and derepresses lineage differentiation genes thereby compromising mESCs identity. Mechanistically, USP7 deubiquitinates and stabilizes SOX2 to repress mesoendodermal (ME) lineage genes. Moreover, USP7 assembles into RYBP-variant polycomb repressive complex 1 (vPRC1) and contributes to Polycomb chromatin domain-mediated repression of ME lineage genes in a catalytic activity-dependent manner. However, USP7 deficient in its deubiquitination function is able to maintain RYBP binding on chromatin to represses primitive endoderm-associated genes in mESCs. Overall, our study demonstrates that USP7 harbors both catalytic and non-catalytic scaffold activity to repress lineage differentiation genes thereby revealing a previously unrecognized role in controlling gene expression and maintaining mESCs identity.

USP7 represses lineage differentiation genes in mouse embryonic stem cells by both catalytic and non-catalytic activity

Project description:USP7, a ubiquitin-specific peptidase (USP), plays an important role in many cellular processes through its catalytic deubiquitination of various substrates. However, its nuclear function to shape the transcriptional network in mouse embryonic stem cells (mESCs) remains poorly understood. Here, we report that USP7 maintains mESCs identity through both catalytic activity-dependent and -independent repression of lineage differentiation genes. Usp7 depletion attenuates SOX2 level and derepresses lineage differentiation genes thereby compromising mESCs pluripotency. Mechanistically, USP7 deubiquitinates and stabilizes SOX2 to repress mesoendodermal (ME) lineage genes. Moreover, USP7 assembles into RYBP-variant Polycomb repressive complex 1 and contributes to Polycomb chromatin-mediated repression of ME lineage genes in a catalytic activity-dependent manner. Importantly, USP7 deficient in its deubiquitination function is able to maintain RYBP binding to chromatin for repressing primitive endoderm-associated genes. Overall, our study demonstrates that USP7 harbors both catalytic and non-catalytic activity to repress different lineage differentiation genes thereby revealing a previously unrecognized role in controlling gene expression for maintaining mESCs identity.

YG001: A Usp7-Tip60 pathway regulates early adipogenesis

Project description:USP7, a dominant DUB activity in 3T3-L1 adipocytes and in mouse adipose tissue, increases Tip60 protein levels, and deubiquitinates Tip60 both in intact cells and in vitro. Treatment with a pan deubiquitinase (DUB) inhibitor, or knockdown of USP7, decreases adipogenesis. Transcriptome analysis reveals a common set of cell cycle genes to be co-regulated by both Tip60 and USP7. Knock down of either factor results in impaired mitotic clonal expansion, an early step in adipogenesis. These results therefore reveal deubiquitination of a transcriptional coregulator to be a key mechanism in the regulation of early adipogenesis Mature 3T3-L1 adipocytes were subjected to RNAi-mediated knock down with control(C), USP7(U)- or Tip60(T)-specific oligonucleotides. For this, 4 replicates of differentiated 3T3-L1 cells were transfected with Amaxa technology. Two days after transfection cells were washed twice with PBS twice and lysed in 0.5ml Trizol (Invitrogen). mRNA expression of Tip60 and USP7 was assessed by qRT-PCR. Amplified cRNA samples were labeled with either cy3 or cy5 and put on microarray together with and oppositely labeled common reference sample consisting of cRNA derived from undifferentiated 3T3-L1 cells.

Kdm2b maintains murine embryonic stem cell status by recruiting PRC1 complex to CpG islands of lineage genes [ChIP-Seq]

Project description:Polycomb group (PcG) proteins play important roles in repressing lineage-specific genes and maintaining the undifferentiated state of mouse embryonic stem cells (mESCs). However, the mechanisms by which PcG proteins are recruited to their targets are largely unknown. Here, we show that the histone demethylase Kdm2b is highly expressed in mESCs and regulated by the pluripotent factors Oct4/Sox2 directly. Depletion of Kdm2b in mESCs causes de-repression of lineage-specific genes and induces early differentiation. The function of Kdm2b depends on its CXXC-ZF domain, which mediates Kdm2b’s genome-wide binding to CpG islands (CGIs). Kdm2b interacts with the core components of the Polycomb repressive complex 1 (PRC1) and recruits the complex to the CGIs of early lineage-specific genes. Thus, our study not only reveals a novel Oct4/Sox2-Kdm2b-PRC1-CGI regulatory axis and its function in maintaining undifferentiated state of mESCs, but also demonstrates a critical function of Kdm2b in recruiting PRC1 to the CGIs of lineage-specific genes to repress their expression. In this dataset, we include the ChIP-seq data of Kdm2b, Ezh2 and Ring1b in both control and Kdm2b knock down mouse embryonbic stem cells.

Genome-wide maps of Usp16, ubH2A and gene expression profiles in wild type and Usp16 knock out mouse embryonic stem cells (ESCs) and embryoid bodies (EBs)

Project description:Polycomb Repressive Complex 1 and histone H2A ubiquitination (ubH2A) contribute to embryonic stem cell (ESC) pluripotency by repressing lineage-specific gene expression. However, whether active deubiquitination co-regulates ubH2A levels in ESCs and during differentiation is not known. Here, we report that the histone H2A deubiquitinase Usp16 regulates H2A deubiquitination and gene expression in ESCs, and importantly, is required for ESC differentiation. Usp16 knockout is embryonic lethal in mice, but does not affect ESC viability or identity. Usp16 binds to the promoter regions of a large number of genes in ESCs and Usp16 binding is inversely correlated with ubH2A levels and positively correlated with gene expression levels. Intriguingly, Usp16-/- ESCs fail to differentiate due to ubH2A-mediated repression of lineage-specific genes. Finally, Usp16, but not the enzymatically inactive mutant, rescues the differentiation defects of Usp16-/- ESCs. Therefore, this study identifies Usp16 and H2A deubiquitination as critical regulators of ESC gene expression and differentiation.

In this dataset, we include the expression data for control and Kdm2b knockdown mouse embryonic stem cells. We analyzed the gene expression in control and Kdm2b knockdown mouse embryonic stem cells using the Affymetrix MoGene-1_0-st-v1 platform.
