Impaired Liver X Receptor alpha phosphorylation affects hepatic chromatin H3K27 acetylation patterns

Project description:Liver X Receptors (LXRα and β) are ligand-activated transcription factors that play a key role in the control of lipid homeostasis, as well as modulation of immunity and inflammation. Besides ligand binding, LXR activity can be regulated by posttranslational modifications, such as phosphorylation. This study aims to assess how changes in the phosphorylation status of LXRα affect the H3K27Ac histone modification, a known marker for active regulatory elements in promoters and enhancers, in livers of mice mice that carry a whole-body phosphorylation deficient-version of LXRα (S196A) compared to wild-type (WT), in response to a high fat-high cholesterol diet.

H3K27 acetylation and gene expression during late spermatogenesis

Project description:ChIP-seq for H3K27 acetylation and RNA-seq were performed during spermatogenesis. We analyzed two representative stages of spermatogenesis: purified pachytene spermatocytes (PS) undergoing meiosis; and postmeiotic round spermatids (RS) from adult testes.

H3K27 Acetylation profile of hypothyroid NCoR1KO mice

Project description:We ablated the expression of the Nuclear Receptor Corepressor 1 specifically in mice livers and rendered them hypothyroid. Then we performed H3K27 acetylation CHIP-Seq. We found decreased H3K27ac in the livers of hypothyroid wild type and NCoR1KO mice. Therefore, we concluded that the thyroid hormone receptor may recruit histone deacetilases independently of NCoR1.

Cytosolic acetyl-CoA promotes histone acetylation predominantly at H3K27 in Arabidopsis

Project description:Acetyl-Coenzyme A (acetyl-CoA) is a central metabolite and the acetyl source for protein acetylation, particularly histone acetylation that promotes gene expression. However, the effect of acetyl-CoA levels on histone acetylation status in plants remains unknown. Here, we show that malfunctioned cytosolic acetyl-CoA carboxylase1 (ACC1) in Arabidopsis leads to elevated levels of acetyl-CoA and promotes histone hyperacetylation predominantly at lysine 27 of histone H3 (H3K27). The increase of H3K27 acetylation (H3K27ac) is dependent on ATP-citrate lyase which cleaves citrate to acetyl-CoA in the cytoplasm, and requires histone acetyltransferase GCN5. A comprehensive analysis of the transcriptome and metabolome in combination with the genome-wide H3K27ac profiles of acc1 mutants, demonstrate the dynamic changes of H3K27ac, gene transcripts and metabolites occurring in the cell by the increased levels of acetyl-CoA. This study suggests that H3K27ac is an important link between cytosolic acetyl-CoA level and gene expression in response to the dynamic metabolic environments in plants.

MCT1-governed pyruvate metabolism is essential for antibody class-switch recombination through H3K27 acetylation

Project description:Monocarboxylate transporter 1 (MCT1) exhibits essential roles in cellular metabolism and energy supply. Although MCT1 is highly expressed in activated B cells, it is not clear how MCT1-governed monocarboxylates transportation is functionally coupled to antibody production during the glucose metabolism. Here, we report that B cell-lineage deficiency of MCT1 significantly influences the class-switch recombination (CSR), rendering impaired IgG antibody responses in Mct1f/fMb1Cre mice after immunization. Metabolic flux reveals that glucose metabolism is significantly reprogrammed from glycolysis to oxidative phosphorylation in Mct1-deficient B cells upon activation. Consistently, activation-induced cytidine deaminase (AID), is severely suppressed in Mct1-deficient B cells due to the decreased level of pyruvate metabolite. Mechanistically, MCT1 is required to maintain the optimal concentration of pyruvate to secure the sufficient acetylation of H3K27 for the elevated transcription of AID in activated B cells. Clinically, we found that MCT1 expression levels are significantly upregulated in systemic lupus erythematosus patients, and Mct1 deficiency can alleviate the symptoms of bm12-induced murine lupus model. Collectively, these results demonstrate that MCT1-mediated pyruvate metabolism is required for IgG antibody CSR through an epigenetic dependent AID transcription, revealing MCT1 as a potential target for vaccine development and SLE disease treatment.
