RNA sequencing data of Ing4;Ing5 compound mutant embryonic mouse hearts (ING4 and ING5 are essential for histone H3 lysine 14 acetylation and epicardial cell lineage development)

ABSTRACT: Inhibitor of growth 4 and 5 (ING4 and ING5) are chromatin-binding proteins in the KAT6A, KAT6B and KAT7 histone acetyltransferase protein complexes. Heterozygous mutations in the KAT6A or KAT6B gene cause human disorders with cardiac defects, but the contribution of their chromatin adaptor proteins to development is unknown. We found that Ing5-/- mice had isolated cardiac ventricular septal defects. ING4 and ING5 are structurally similar proteins, suggesting a degree of redundancy. Combined loss of ING4 and ING5 caused developmental arrest at embryonic day E8.5, loss of histone H3 lysine 14 acetylation (H3K14ac) and a reduction in H3K23ac levels. Ing4+/-Ing5-/- hearts showed a paucity of epicardial cells and epicardium-derived cells, failure of myocardium compaction and coronary vasculature defects, accompanied by a reduction in the expression of epicardium genes. Our findings suggest that ING4 and ING5 are essential for heart development and promote epicardium and epicardium-derived cell fates and mutation of the human ING5 gene as a possible cause of isolated ventricular septal defects.

RNA sequencing data of Ing4;Ing5 double knock-out embryonic mouse hearts

Project description:Inhibitor of growth 4 and 5 (ING4 and ING5) are chromatin-binding proteins in the KAT6A, KAT6B and KAT7 histone acetyltransferase protein complexes. Heterozygous mutations in the KAT6A or KAT6B gene cause human disorders with cardiac defects, but the contribution of their chromatin adaptor proteins to development is unknown. We found that Ing5–/– mice had isolated cardiac ventricular septal defects. ING4 and ING5 are structurally similar proteins, suggesting a degree of redundancy. Combined loss of ING4 and ING5 caused developmental arrest at embryonic day E8.5, loss of histone H3 lysine 14 acetylation (H3K14ac), a reduction in H3K23ac levels and disruption of developmental gene expression in Ing4–/–Ing5–/– compared to control embryos. E12.5 Ing4+/–Ing5–/– hearts showed a paucity of epicardial cells and epicardium-derived cells, failure of myocardium compaction and coronary vasculature defects, accompanied by a reduction in the expression of epicardium genes compared to control hearts. In addition, a reduction in the expression of genes required for cell adhesion, both in whole E8.75 Ing4–/–Ing5–/– embryos and in E10.5 Ing4+/–Ing5–/– hearts compared to controls was observed. In vitro assessment of fibroblast and proepicardium explants revealed cell spreading and outgrowth defects. Our findings suggest that ING4 and ING5 are essential for heart development and promote epicardium and epicardium-derived cell fates and mutation of the human ING5 gene as a possible cause of isolated ventricular septal defects.

ING4 ChIP-chip in HT1080 cells

Project description:Aberrations in chromatin dynamics play a fundamental role in tumorigenesis, yet relatively little is known of the molecular mechanisms linking histone lysine methylation to neoplastic disease. ING4 (Inhibitor of Growth 4) is a native subunit of an HBO1 histone acetyltransferase (HAT) complex and a tumor suppressor protein. Here we show a critical role for the specific read-out of histone H3 trimethylated at lysine 4 (H3K4me3) by the ING4 PHD finger in mediating ING4 gene expression and tumor suppressor functions. The interaction between ING4 and H3K4me3 augments the acetylation activity of HBO1 on H3 tails, and drives H3 acetylation at ING4 target promoters to effect a DNA damage-dependent gene expression program. Further, ING4 facilitates apoptosis in response to genotoxic stress and inhibits anchorage-independent cell growth, and these functions are dependent on ING4 interactions with H3K4me3. Together, our results demonstrate a mechanism for brokering crosstalk between H3K4 methylation and histone H3 acetylation, and reveal a new molecular link between chromatin modulation and tumor suppressor mechanisms.

The histone acetyltransferase KAT6B is required for haematopoietic stem cell development and function

Project description:The histone lysine acetyltransferase KAT6B (MYST4, MORF, QKF) is the target of recurrent chromosomal translocations causing haematological malignancies with poor prognosis. Using Kat6b germline deletion and overexpression in mice, we determined the role of KAT6B in the haematopoietic system. We found that KAT6B sustained the fetal haematopoietic stem cell pool but did not affect viability or differentiation. KAT6B was essential for normal levels of histone H3 lysine 9 (H3K9) acetylation but not for a previously proposed target, H3K23. Compound heterozygosity of Kat6b and the closely related gene, Kat6a, abolished haematopoietic reconstitution after transplantation. KAT6B and KAT6A cooperatively promoted transcription of genes regulating haematopoiesis, including the Hoxa cluster, Pbx1, Meis1, Gata family, Erg and Flt3. In conclusion, we identified the haematopoietic processes requiring Kat6b and showed that KAT6B and KAT6A synergistically promoted HSC development, function and transcription. Our findings are pertinent to current clinical trials testing KAT6A/B inhibitors as cancer therapeutics.
