ATAC-seq analyses with wild-type and PML KO mESCs

Project description:Promyelocytic leukemia (PML) body is a phase-separated nuclear structure composed of various proteins including several chromatin regulators, and physically associates with chromatin, implying its crucial roles for particular genome functions. To investigate functional roles of PML bodies in chromatin organization, we conducted ATAC-seq with wild-type and PML KO mESCs.

ChIP-seq analysis of wild-type and PML KO mESCs

Project description:Promyelocytic leukemia (PML) body is a phase-separated nuclear structure composed of various proteins including several chromatin regulators, and physically associates with chromatin, implying its crucial roles for particular genome functions. To investigate roles of PML bodies in transcriptional regulation, we conducted ChIP-seq analysis for histone modifications, including H3K4me3, H3K27ac, H3K27me3, and H3K9ac with wild-type and PML knockout mESCs.

Recruitment of TRIM33 to cell-context specific PML nuclear bodies regulates Nodal signaling in mESCs

Project description:TRIM33 is a chromatin reader required for mesendoderm differentiation upon activation of Nodal signaling. But, its role in mESCs is still elusive. Here, we found that TRIM33 co-localizes with promyelocytic leukemia nuclear bodies (PML NBs) specifically in mESCs to mediate Nodal signaling-directed transcription of Lefty1/2. We showed that TRIM33 puncta formation in mESCs depends on PML and specific assembly of PML NBs. Moreover, TRIM33 and PML co-regulate Lefty1/2 expression in mESCs. In addition, both PML and mESCs-specific PML NBs are required for TRIM33 recruitment at Lefty1/2 loci. Remarkably, PML NBs directly associate with the Lefty1/2 loci in mESCs. Finally, a TurboID proximity labeling experiment confirmed that TRIM33 is highly enriched in the mESCs-specific PML NBs. Thus, our study provides the mechanistic insight about TRIM33 condensate in regulating Nodal signaling-directed transcription in mESCs, it also reveals that PML NBs recruit distinct sets of client proteins in cell context dependent manner.

Quantitative Analysis of Wild Type(wt) and Setd2 knockout(ko) mESCs Transcriptomes [RNA-Seq]

Project description:Purpose: This study aimed at exploring the deregulated genes in setd2 knockout mESCs compared with wt, more particularly to find the mechanism controlled by setd2,which was required for endoderm differentiation. Methods: Setd2 wt and ko mESCs were generated by deep sequencing, using Illumina GAIIx. Using Avadis NGS (version:1.3) software to analyze the sequence reads that passed quality filter to acquire the expression level of all genes. qRT–PCR validation was performed usingSYBR Green assays. Results: Using an optimized data analysis workflow, we mapped about 80 million sequence reads per sample to the mouse genome (build mm9) and identified 17,827 transcripts in the sted2 wt and ko mESCs. About 2,516 genes were deregulated in setd2 ko mESCs, more than 10 genes were validated using qRT-PCR. Conclusions: Through RNA-seq,we noticed that a subset of genes that related to MAPK signaling pathways were down-regulated in ko mESCs. This provided a bridge to connect setd2 and mESCs endoderm differentiation. One wt and one ko mESCs were generated by deep sequencing, using Illumina GAIIx.

Gene expression profiling of Pml wt and Pml KO mice liver after fasted 6h

Project description:The Pml gene is essential to the formation of PML nuclear bodies, domains which have been associated with various functions such as apoptosis/senescence, DNA repair and cell proliferation( Lallemand-Breitenbach 2010). PML-NBs formation is regulated by cellular stress including oxidative stress(Jeanne 2010, de The 2012). To investigate the role of PML in ROS response in vivo, we analyse the expression difference betweem Pml wt and Pml KO under fasted condition, which easily up-regulate ROS in BALB/cByJ background

Gene expression profiling of Pml wt and Pml KO mice liver with acetaminophen (apap) overdose (300mg/kg) i.p.

Project description:The Pml gene is essential to the formation of PML nuclear bodies, domains which have been associated with various functions such as apoptosis/senescence, DNA repair and cell proliferation( Lallemand-Breitenbach 2010). PML-NBs formation is regulated by cellular stress including oxidative stress(Jeanne 2010, de The 2012). To investigate the role of PML in ROS response in vivo, we analyse the expression difference to the acetaminophen toxicity, which is initiated by ROS, in Pml wt and Pml KO mice.
