Effect of G2E3 knockout and SUV39H2 knockout on gene expression and heterochromatin repeats DNA transcription in HeLa cells.

Project description:To investigate the correlation between G2E3 and SUV39H2 in regulating gene expression and heterochromatin repeats DNA transcription, we generated G2E3 knockout HeLa cells line and SUV39H2 knockout HeLa cells line by the CRISPR-Cas9 system essentially as described (Ran et al., 2013), and performed gene expression profiling analysis and repeats DNA transcription profiling analysis using data obtained from RNA-seq.

LncRNA Gas5 directs SUV39H2 to establish heterochromatin and maintain genome stability

Project description:Constitutive heterochromatin, characterized by histone H3 lysine 9 trimethylation (H3K9me3), is essential for genome stability, pluripotency, and developmental fidelity. While the SUV39H histone methyltransferases catalyze H3K9me3 deposition, their locus-specific targeting mechanisms remain unclear. Here, via RNA depletion or RNA-binding affinity mutation, we establish that RNA binding is indispensable for SUV39H2 recruitment to chromatin and H3K9me3 maintenance in mouse embryonic stem cells (ESCs). Through RNA immunoprecipitation sequencing (RIP-Seq) and functional validation, we identify the long non-coding RNA Gas5 as a specific SUV39H2 interactor. Depletion of Gas5 or disruption of the SUV39H2–RNA interaction leads to the loss of self-renewal capacity of ESCs, abolishes H3K9me3 enrichment, along with profound genomic instability, mitotic errors, and γH2AX foci accumulation. These findings reveal a critical lncRNA-dependent mechanism governing the SUV39H2–H3K9me3 axis, which directly couples RNA metabolism to the preservation of pluripotency and genome integrity in stem cells.

ATAC-seq of DP thymocytes from Suv39h1 and Suv39h2 double knockout chimeric mice

Project description:H3K9me3-dependent heterochromatin is critical for the silencing of repeat-rich pericentromeric regions and also has key roles in repressing lineage-inappropriate protein-coding genes for healthy cellular function. Within all eukaryotic nuclei, heterochromatin and euchromatin are spatially segregated, with euchromatin typically located in the nuclear interior and heterochromatin at the nuclear periphery. Here we investigate the changes in DNA accessibilty in the absence of H3K9me3-dependent heterochromatin by performing ATAC-seq in primary immune cells deficient in both Suv39h1 and Suv39h2 (Suv39DKO), the major mammalian histone methyltransferase enzymes which catalyse heterochromatic H3K9me3 deposition.

Specificity, propagation and memory of pericentric heterochromatin in mouse fibroblasts

Project description:We assembled a quantitative map for the abundance and interactions of 16 factors related to PCH in living cells and found that stably bound complexes of the histone methyltransferase Suv39h1/2 demarcate the PCH state. From the experimental data we developed a predictive mathematical model that explains how chromatin-bound Suv39h1/2 complexes act as nucleation sites and propagate a spatially confined PCH domain with elevated histone H3 trimethylation levels via chromatin dynamics. Enrichment of HP1, Suv39h1/h2, H3K9me3 and H3K36me3 was assessed by ChIP-seq in NPCs derived from ESCs showing differential occupation at intergenic major satellite repeats and enrichment of heterochromatin factors. ChIP-seq of HP1, Suv39h1, Suv39h2, H3K9me3, H3K36me3 in NPCs
