H4K20me3 methyltransferase SUV420H2 shapes the chromatin landscape of pluripotent embryonic stem cells

Project description:Heterochromatin, which is a densely packed chromatin state that is transcriptionally silent, is a critical regulator of gene expression. However, it is unclear how the repressive histone modification, H4K20me3, or the histone methyltransferase, SUV420H2, regulate embryonic stem (ES) cell fate by patterning the epigenetic landscape. Here, we report that depletion of SUV420H2 leads to a near complete loss of H4K20me3 genome-wide, dysregulated gene expression, and delayed ES cell differentiation. SUV420H2-bound regions are enriched with repetitive DNA elements, which are de-repressed in SUV420H2 knockout ES cells. Moreover, SUV420H2 regulation of H4K20me3-marked heterochromatin controls chromatin architecture, including fine-scale interactions between gene regulatory elements in pluripotent ES cells. SUV420H2 plays a critical role in stabilizing the three-dimensional (3D) chromatin landscape of ES cells, where loss of SUV420H2 results in A/B compartment switching, perturbed chromatin insulation, and altered chromatin interactions of pericentric heterochromatin, indicative of localized decondensation. In addition, depletion of SUV420H2 resulted in compromised interactions between H4K20me3 and gene regulatory regions. Together, these findings describe a novel role for SUV420H2 in regulating the chromatin landscape of ES cells.

SUV420H2 over-expression affects on gene expression in human breast cancer MDA-MB-231 cells

Project description:Analysis of breast cancer MDA-MB-231 cells stably over-expressing SUV420H2, a histone H4K20 methyltransferase. Several genes were significantly up- or down-regulated. Results provide insight into the molecular mechanism by which H4K20me3 contributes to gene expression. SUV420H2 stably over-expressing MDA-MB-231 cells were cloned. Then total RNA was extracted from the SUV420H2 over-expressing cells and the parental MDA-MB-231 cells.

Loss of SUV420H2-dependent chromatin compaction drives right-sided colon cancer progression [CGH]

Project description:Epigenetic processes regulating gene expression contribute markedly to epithelial cell plasticity in colorectal carcinogenesis. The lysine methyltransferase SUV420H2 comprises an important regulator of epithelial plasticity and is primarily responsible for trimethylation of H4K20 (H4K20me3). Loss of H4K20me3 has been suggested as a hallmark of human cancer due to its interaction with DNMT1. However, the role of Suv4-20h2 in colorectal cancer is unknown.
