Project description:Neural development requires crosstalk between signaling pathways and chromatin. In this study, we demonstrate that neurogenesis is promoted by an interplay between the TGFM-NM-2 pathway and the H3K27me3 histone demethylase (HDM) JMJD3. Genome-wide analysis showed that JMJD3 is targeted to gene promoters by Smad3 in neural stem cells (NSCs) and is essential to activate TGFM-NM-2-responsive genes. In vivo experiments in chick spinal cord revealed that the generation of neurons promoted by Smad3 is dependent on JMJD3 HDM activity. Overall, these findings indicate that JMJD3 function is required for the TGFM-NM-2 developmental program to proceed. We immunoprecipitate endogenous Smad3 or JMJD3 proteins from neural stem cells treated with TGFb for 30 minutes.

Project description:ChIP seq of endogenous Smad3 and JMJD3 proteins in mouse embryonic neural stem cells treated with TGFbeta during 30 minutes. Neural stem cells were treated with TGFbeta during 30 minutes, and then chromatin immunoprecipitation was carried out with specific JMJD3 or Smad3 antibodies. Positive and negative controls for each immunoprecipitation were checked before sequencing. Input was used to normalized the sequencing results.

Project description:Neural development requires crosstalk between signaling pathways and chromatin. In this study, we demonstrate that neurogenesis is promoted by an interplay between the TGFβ pathway and the H3K27me3 histone demethylase (HDM) JMJD3. Genome-wide analysis showed that JMJD3 is targeted to gene promoters by Smad3 in neural stem cells (NSCs) and is essential to activate TGFβ-responsive genes. In vivo experiments in chick spinal cord revealed that the generation of neurons promoted by Smad3 is dependent on JMJD3 HDM activity. Overall, these findings indicate that JMJD3 function is required for the TGFβ developmental program to proceed.

Project description:Several signaling pathways require JMJD3 binding to promoters to activate the expression of target genes. Despite the known H3K27me3 demethylase activity of JMJD3 the transcriptional coactivator mechanism remains unclear. Here we reveal that JMJD3 promotes transcription of TGFb responsive genes through regulation of RNAPII progression on gene bodies. ChIPseq experiments demonstrate that upon TGFb treatment, JMJD3 and RNAPII.ser2P colocalyze extensively along intragenic regions of TGF target genes. M-BM- According to these data, genome wide analysis shows that JMJD3 dependent TGF target genes are enriched in H3K27me3 prior to TGF signaling pathway activation. M-BM- Further molecular analysis indicate that JMJD3 removes H3K27me3 and pave the way for the RNAPII.Overall, these findingsM-BM- uncover the mechanism ofM-BM- JMJD3 function in transcriptional activation We performed chromatin immunoprecipitation followed by sequencing (ChIPseq) of H3K27me3 mark in mouse neural stem cells growing under standard conditions. We also performed ChIPseq of elongating RNAPII (Ser2P) and JMJD3 in neural stem cells stimulated with TGFb cytokine.

Project description:The JmjC domain containing protein JMJD3/KDM6B catalyses H3K27me3 and H3K27me2 demethylation. JMJD3 appears to be highly regulated at the transcriptional level and is upregulated in response to diverse stimuli such as differentiation inducers and stress signals. Accordingly, JMJD3 has been linked to the regulation of different biological processes such as differentiation of embryonic stem cells, inflammatory responses in macrophages, and induction of cellular senescence via regulation of the INK4A-ARF locus. Here we show here that JMJD3 interacts with the tumour suppressor protein p53. We find that the interaction is dependent on the p53 tetramerization domain. Following DNA damage, JMJD3 is transcriptionally upregulated and by performing genome-wide mapping of JMJD3, we demonstrate that it binds genes involved in basic cellular processes, as well as genes regulating cell cycle, response to stress and apoptosis. Moreover, we find that JMJD3 binding sites show significant overlap with p53 bound promoters and enhancer elements. The binding of JMJD3 to p53 target sites is increased in response to DNA damage, and we demonstrate that the recruitment of JMJD3 to these sites is dependent on p53 expression. Therefore, we propose a model in which JMJD3 is recruited to p53 responsive elements via its interaction with p53 and speculate that JMJD3 could act as a fail-safe mechanism to remove low levels of H3K27me3 and H3K27me2 to allow for efficient acetylation of H3K27.
