H3K9me3 and H3K36me3 ChIP-seq in WT and H3.3 G34R mouse ES cells
Sequencing of paediatric gliomas has identified two common substitution mutations (K27M and G34R) in genes encoding histone H3.3. We introduced a single-copy H3.3 G34R targeted mutation in mouse ES cells and observed gains in H3K36me3 and H3K9me3 across the genome. Altered chromatin profiles correlated with enrichment of KDM4 A/B/C, a histone lysine (K9/K36) demethylase. RNA-seq of H3.3 G34R mutant showed disrupted gene expression patterns which also correlated with KDM4 enrichment. Expression of a single copy of H3.3 G34R at endogenous levels was sufficient to genocopy KDM4 triple-KO cells as determined by ChIP-seq and RNA-seq. Overall design: 4 samples - ChIP-seq of H3K9me3 and H3K36me3 in WT control and H3.3 G34R mutant cells
