Figure Lengend Snippet: a Cluster heatmap (k-means, 4) of RNA-seq data analyzed with Deseq2 for differential expression (FDR < 0.05) for the indicated cell lines. Heatmap shows z-score normalized counts of differentially expressed PRC2 target genes identified by H3K27me3 positive promoters in WT mESCs ( n = 4986). Based on three independent biological replicates ( n = 3). b MA plots showing mean changes in gene expression from Deseq2 analysis based on three independent biological replicates ( n = 3). Indicated with red dots are significantly upregulated genes in Suz12 KO mESCs filtered with log2 expression fold change> 1 and FDR < 0.05. The mean expression of the upregulated genes in Suz12 KO mESCs are traced in the indicated cell lines. c Bar plot showing the fraction of the 1326 upregulated PRC2 target genes in Suz12 KO mESCs that are fully or partially rescued in the indicated cell lines (see methods for filtering criteria). Statistical significance was calculated using Fisher’s exact test, two-tailed (* p < 0.05; ** p < 0.01; *** p < 0.001, **** p < 0.0001). Source data are provided as a Source Data file. d Bar plot showing the percentage of beating cluster identified on day 10 after induction of embryoid body differentiation in the indicated cell lines. The plot is representative of at least three independent experiments. e Mean H3K4me3 CUT&RUN signals (RPKM) ( n = 2) in indicated cell lines within a 40 Kb window centered on 7732 H3K27me3 positive promoter peaks identified in WT mESCs. f Mean H3K4me3 CUT&RUN signals (RPKM) within 40 Kb window centered on PRC2 target promoters for the H3K9me3-rescued versus non-rescued genes in Suz12 KO mESCs expressing S12 N :SUV2. g Mean H3K9me3 CUT&RUN signal (peak-normalized) within 40 Kb window centered on PRC2 target promoters for the H3K9me3-rescued versus non-rescued genes in Suz12 KO mESCs expressing S12 N :SUV2 ( n = 2). h Heatmaps of sequence depth normalized H3K4me3 CUT&RUN data (blue), SUZ12 ChIP-seq data (S12 N fusion proteins) (red), and peak-normalized H3K9me3 CUT&RUN data (black) at PRC2 target promoters in RBBP5-FKBP12 F36V + Suz12 KO mESCs expressing S12 N :SUV2 treated with dTAG-13 or DMSO for 24hrs. Top: Average plots of the mean signal for the region displayed in heatmaps. i Bar plot of relative gene rescue (%) in RBBP5-FKBP12 F36V + Suz12 KO mESCs expressing S12 N :SUV2 treated with dTAG-13 for 24 h with DMSO treatment for 24 hrs as reference ( n = 3).
Article Snippet: For KDM4 inhibitor experiments, Suz12 KO mESCs expressing S12 N :SUV2 were treated with 50 nM or 100 nM of the KDM4C inhibitor QC6352 (MedChemExpress) for 96 h with media renewal every 24 h. An overview of cell lines can be found in Supplementary Table .
