Effect of conditional triple-knockout of Jmjd2a/Kdm4a, Jmjd2b/Kdm4b and Jmjd2c/Kdm4c or overexpression of KDM4C/JMJD2C mutants with different phase separation ability on gene expression in mouse embryonic stem cells. [HiChIP]

ABSTRACT: To investigate the functions of JMJD2/KDM4 family in mouse embryonic stem cells (mESCs), we treat the the conditional triple-knockout mESCs of Jmjd2a/Kdm4a, Jmjd2b/Kdm4b and Jmjd2c/Kdm4c with 4-hydroxytamoxifen (4-OHT) for 72h. Besides, to investigate whether JMJD2/KDM4 phase separation affects Enhancer-Promoter loops, we generated IDR-truncated JMJD2C/KDM4C (Mut) to disrupt its phase separation ability, and rescued it by by fusing two IDRs in other species (hIDR1 and hIDR2). Further, to investigate whether the functions of JMJD2/KDM4 are catalytic-dependent, we also generated catalytic mutants of JMJD2B and JMJD2C. We overexpressed those phase separation or catalytic mutants in the aboved mESCs separately and TKO endogenous Jmjd2 by adding 4-OHT 72h (for phase separation mutants) or 36h (for catalytic mutants).

Jmjd2a and Jmjd2c regulate H3K9me3 and H3K36me3 at H3K4me3 positive TSSs being essential for ESC self-renewal and embryogenesis (microarray)

Project description:We have characterized the role of the Jmjd2/Kdm4 proteins in embryonic stem cell (ESC) biology, histone methylation and gene regulation. The Jmjd2 proteins are H3K9/H3K36 histone demethylases and three Jmjd2 family members are expressed in ESCs: Jmjd2a/Kdm4a, Jmjd2b/Kdm4b and Jmjd2c/Kdm4c/Gasc1. We find that specifically Jmjd2a and Jmjd2c exert redundant functions, which are essential for ESC self-renewal and early embryonic development. ChIP-seq studies show that Jmjd2a and Jmjd2c both localize to H3K4me3 marked regions, where they have general and widespread roles preventing the accumulation of especially H3K9me3, but also H3K36me3. Jmjd2 catalytic activity is required for ESC maintenance, and increased H3K9me3 levels in knockout ESCs compromise the expression of several Jmjd2a/c targets, including genes that are important for ESC self-renewal. Thus, continual removal of H3K9 promoter methylation by Jmjd2 demethylases represents a novel mechanism ensuring transcriptional competence and stability of the pluripotent cell identity.

Jmjd2c/Kdm4c facilitates the assembly of essential enhancer-protein complexes at the onset of embryonic stem cell differentiation

Project description:Jmjd2/Kdm4 H3K9-demethylases cooperate in promoting mouse embryonic stem cell (ESC) identity. However, little is known about their importance at the exit of ESC pluripotency. Here, we uncover that Jmjd2c facilitates this process by stabilizing the assembly of Mediator-Cohesin complexes at lineage-specific enhancers. Functionally, we show that Jmjd2c is required in ESCs to initiate appropriate gene expression programs upon somatic multi-lineage differentiation. In the absence of Jmjd2c, differentiation is stalled at an early post-implantation epiblast-like stage, while Jmjd2c-knockout ESCs remain capable of forming extra-embryonic endoderm derivatives. Dissection of the underlying molecular basis revealed that Jmjd2c is re-distributed to lineage-specific enhancers during ESC priming for differentiation. Interestingly, Jmjd2c-bound enhancers are co-occupied by the H3K9-methyltransferase G9a/Ehmt2, independently of its H3K9-modifying activity. Loss of Jmjd2c abrogates G9a recruitment and furthermore destabilizes loading of the Mediator and Cohesin components Med1 and Smc1a at newly activated and poised enhancers in ESC-derived epiblast-like cells. These findings unveil Jmjd2c-G9a as novel enhancer-associated factors, and implicate Jmjd2c as a molecular scaffold for the assembly of essential enhancer-protein complexes with impact on timely gene activation.

The Demethylase JMJD2C/KDM4C Localizes to H3K4me3 Positive Transcription Start Sites (ChIP-seq MEFs)

Project description:We have mapped binding sites for the histone demethylase, Jmjd2c/Kdm4c/Gasc1, in mouse embryonic fibroblasts (MEFs) and the impact of Jmjd2c depletion on H3K9me3 and H3K36me3 distributions. ChIP-seq was performed using antibodies recognizing Jmjd2c, H3K9me3 or H3K36me3. Chromatin was obtained from conditional Jmjd2c knockout MEFs cultured in the absence or presence of OHT to induce activation of Cre recombinase and loss of Jmjd2c expression.
