Genome-wide acetylated histone 3 lysine 9 (H3K9ac) in HDAC3-depleted liver rescued with deacectylase-dead HDAC3 mutants

ABSTRACT: We found that several deacetylase-dead HDAC3 mutants were able to rescue the metabolic phenotype of HDAC3-depleted livers. Here we profile the histone acetylation in the presence of different HDAC3 mutants in mouse liver. Deacetylase-dead HDAC3 mutants, including HAHA, KA, YF and HEBI, were introduced into HDAC3-depleted (Cre) mouse livers by virus along with wild-type (WT) HDAC3 as a control. Livers were harvested at 5 pm (ZT 10) and subjected to ChIP with anti-H3K9ac antibodies followed by deep sequencing.

Histone Deacetylase 3 is an Epigenomic Brake in Macrophage Alternative Activation (ChIP-Seq)

Project description:We report the genomic regions enriched in Histone Deacetylase 3 (HDAC3) in mouse bone marrow derived macrophages. Furthermore, we also report the genomic acetylation pattern on Histone 3, Lysine 9 (H3K9) in macrophages with and without HDAC3 and/or treated with Th2 cytokine IL-4. HDAC3 enriched genomic regions in mouse bone marrow dervied macrophages and H3K9Ac enriched genomic regions in wild-type macrophages and macrophages treated with IL-4 and/or deficient in HDAC3.

HDAC3 preferentially binds to RUNX1 in t(8;21) AML cells and collaborates with RUNX1 to repress AML1-ETO-mediated transcriptional activation

Project description:Human histone deacetylase 3 (HDAC3) plays an important role in gene transcription in diseased human cells, such as leukemia. The t(8;21) chromosomal translocation is one of the most commonly observed genetic abnormalities associated with acute myeloid leukemia. This translocation generates the AML1-ETO fusion protein between the wild-type RUNX1 transcription factor and wild-type ETO transcriptional corepressor. To better understand the role of HDAC3 in t(8;21) leukemogenesis, the human HDAC3-containing complexes were isolated from stably-transfected HeLa cells by using anti-FLAG immunoprecipitation. The resulting complexes were resolved in SDS-PAGE. The components of the complexes were identified using LC-MS/MS. We report here that the human RUNX1 transcription is a component of the HDAC3 complexes. We demonstrate that HDAC3 and RUNX1 collaboratively repress AML1-ETO-mediated transcription. These results reveal new insight into how AML1-ETO, RUNX1, and HDAC3 crosstalk to deregulate gene transcription in t(8;21) leukemia cells.

Gene expression in mouse liver depleted of HDAC3

Project description:Liver-specific depletion of HDAC3 leads to liver steatosis (fatty liver), suggesting disregulation of lipid metabolism. This is correlated with changes in lipid metabolic gene expression. Livers depleted of HDAC3 were removed from 12 week old male HDAC3 fl/fl mice (loxP sites flanking exon 4 to 7 of the HDAC3 gene encoding the catalytic domain of HDAC3) one week after the injection of AAV2/8-Tbg-Cre virus. Livers from the HDAC3 fl/fl mice injected with AAV2/8-Tbg-GFP were used as normal controls. mRNA was extracted from 100mg mouse liver samples and hybridized to Affymetrix microarrays. For each group (HDAC3 depleted liver and normal liver), we have 5 samples from different mice.

Histone Deacetylase 3 is an Epigenomic Brake in Macrophage Alternative Activation (microarray)

Project description:Macrophages, a key cellular component of inflammation, become functionally polarized in a signal- and context-specific manner. Th2 cytokines such as IL-4 polarize macrophages to a state of alternative activation that limits inflammation and promotes wound healing. Alternative activation is mediated by a transcriptional program that is influenced by epigenomic modifications including histone acetylation. To determine if Histone Deacetylase 3 (HDAC3) has a role in macrophage polarization including alternative activation, we have performed global gene expression analysis in macrophages with and without HDAC3 and with or without IL-4 exposure. From this data, we conclude that macrophages lacking histone deacetylase 3 (HDAC3) display a polarization phenotype similar to IL-4 induced alternative activation and furthermore are hyper-responsive to IL-4 stimulation. Mouse bone marrow derived macrophages were obtained from both control and HDAC3 KO animals and treated with vehicle control (BSA) or IL-4 for 24 hours. RNA was isolated and subjected to analysis using an Agilent Whole Genome Microarray Kit.

Gene expression profiling of HDAC3-depleted mouse liver rescued with wild-type exogenous HDAC3

Project description:We have shown that intravenous injection of HDAC3 floxed mice with adeno-associated virus (AAV) expressing Cre depletes hepatic HDAC3, upregulates lipogenic gene expression, and causes fatty liver. When AAV-Flag-HDAC3 wild-type (WT) is co-injected along with AAV-Cre, the exogenous HDAC3 is expressed at endogenous levels and can completely rescue fatty liver phenotype. Here we profile transcriptome of the rescued WT livers in comparison with HDAC3-depleted (KO) livers. 4-months old C57BL/6 male mice were co-injected with AAV-Cre or AAV-Cre plus AAV-Flag-HDAC3. Mice were fed ad libitum and harvested at 5 pm (ZT10) at 2-weeks post-injection. Liver total RNA was extracted and hybridized to Affymetrix Mouse Gene 1.0ST array.
