Project description:<p>BACKGROUND: Single ventricle congenital heart disease (SVCHD) is a severe form of cardiac malformation in which there is only one functional ventricle. The Fontan operation is the current standard of care for SVCHD. Almost all patients who have undergone the Fontan operation develop liver fibrosis at a young age, resulting in a condition known as Fontan-associated liver disease (FALD). The pathogenesis and mechanisms underlying FALD remain little understood, hindering development of effective therapies.</p><p>OBJECTIVES: We aimed to present a comprehensive multiomic analysis of human FALD, thereby revealing the fundamental biology and pathogenesis of FALD. </p><p>METHODS: We recently generated a single-cell transcriptomic and epigenomic atlas of human FALD using snRNA-ATAC-seq, which revealed profound metabolic reprogramming in FALD. Here we applied liquid chromatography-mass spectrometry (LC-MS) based untargeted metabolomics to unveil the metabolomic landscape of human FALD, using liver samples/biopsies from age and gender-matched healthy donors and FALD patients (n=12 per group). Extracted liver metabolites were analyzed by C18 high performance liquid chromatography (HPLC) and hydrophilic interaction chromatography (HILIC) followed by high resolution MS on Orbitrap. Statistical and bioinformatics analyses were performed to identify altered metabolites and metabolic pathways in FALD. These results were integrated with recently published snRNA-ATAC-seq and serum metabolomics datasets to present a comprehensive multiomic atlas of FALD. </p><p>RESULTS: We discovered profound metabolic abnormalities in livers of patients with early-stage FALD, particularly amino acid metabolism, peroxisomal fatty acid oxidation, cytochrome P450 system, glycolysis, TCA cycle, ketone body metabolism and bile acids metabolism. Integrated analyses with liver snRNA-ATAC-seq and serum metabolomics data unveiled the transcriptional mechanisms driving this metabolic reprogramming and the crosstalk between liver and the rest of the body. Comparison with human metabolic dysfunction-associated fatty liver disease (MAFLD) and metabolic dysfunction-associated steatohepatitis (MASH) revealed dysregulated amino acid metabolism as a common metabolic abnormality. </p><p>CONCLUSIONS: Our comprehensive multiomic atlas of human FALD reveals the fundamental biology and pathogenesis mechanisms of FALD.</p>

Project description:Aging is a universal biological phenomenon linked to many diseases, such as cancer or neurodegeneration. However, the molecular mechanisms underlying aging, or how lifestyle interventions such as cognitive stimulation can ameliorate this process, are yet to be clarified. Here, we performed a multi-omic profiling, including RNA-seq, ATAC-seq, ChIP-seq, EM-seq, SWATH-MS and single cell Multiome scRNA and scATAC-seq, in the dorsal hippocampus of young and old mouse subjects which were subject to cognitive stimulation using the paradigm of environmental enrichment. In this study we were able to describe the epigenomic landscape of aging and cognitive stimulation.

Project description:We describe an assay for transposase-accessible chromatin using sequencing (ATAC-seq), based on direct in vitro transposition of sequencing adaptors into native chromatin, as a rapid and sensitive method for integrative epigenomic analysis. ATAC-seq captures open chromatin sites using a simple two-step protocol with 500–50,000 cells and reveals the interplay between genomic locations of open chromatin, DNA-binding proteins, individual nucleosomes and chromatin compaction at nucleotide resolution. We discovered classes of DNA-binding factors that strictly avoided, could tolerate or tended to overlap with the nucleosome. Using ATAC-seq maps of human CD4+ T cells from a proband obtained on consecutive days, we demonstrated the feasibility of analyzing an individual’s epigenome on a timescale compatible with clinical decision-making. We examined chromatin structure using ATAC-seq in 2 cell types (GM12878 cell line, purified CD4+ T cells).

Project description:We report the IFN-induced dynamics in murine splenic B cells. Male C57BL/6 mice were injected subcutaneously with 10,000U IFNa and spleens were removed at 90min. B cells were negatively isolated using magnetic beads and profiled for the chromatin configuration by ATAC-seq. Profilings of chromatin configuration by ATAC-seq (0 and 90min, biological duplicate for each).

Project description:In patients with hepatocellular carcinoma (HCC) meeting the Milan criteria, liver transplantation (LT) is an effective therapy. This study aims to define the survival-related molecular biological features helping precisely identifying the patients with HCC beyond the Milan criteria who have acceptable outcomes. In the derivation cohort (n = 122), integrated analyses of tumor tissues are conducted using RNA sequencing (RNA-seq), proteomic landscape and transposase-accessible chromatin sequencing (ATAC-seq). Based on transcriptomics, three subgroups that significantly differ in overall survival were identified in the derivation cohort, and these findings are validated in an independent cohort. In-depth bioinformatics analysis using RNA-seq and proteomics reveals that the promotion of cancer stemness by cancer-associated fibroblasts (CAFs) can be responsible for the negative biological characteristics observed in high-risk HCC patients. The ATAC-seq identifies key factors regulating transcription, which may bridge CAF infiltration and stemness. Finally, we demonstrate that the CAF-derived CXCL12 sustains the stemness of HCC cells by promoting XRCC5 through CXCR4.

Project description:We over-expressed an epigenetic regulator in a glioblastoma (GBM) primary culture from an adult patient. These GBM cells have cancer stem cell phenotypes, as they have self-renewal properties and tumor initiation potential when transplanted in immunocompromised mice. ATAC-seq was performed on cells over-expressing the epigenetic regulator and control cells expressing EGFP. ATAC-Seq on glioblastoma cells that over-express EGFP or an epigenetic regulator.

Project description:The t(7;12) AML subtype in pediatric patients is associated with upregulation of homeodomain protein MNX1 as the initiating event for leukemogenesis. In this study, we investigated the downstream targets of MNX1 and their relationship to the histone modifications previously observed to be mediated by MNX1. Using a comprehensive approach combining TMT mass spectrometry, RNA-Seq, qPCR, ACT-seq, ATAC-seq, and ChIP-qPCR, we identified PBXIP1 along with its associated pioneer transcription factor PBX1 and PBX4 as downstream targets of MNX1. MNX1 binding to the Pbx1 promoter triggered its transcriptional activation, which was associated with an increase in the activating histone mark H3K4me3 and a decrease in the repressive mark H3K27me3 at the promoter site. Notably, despite the transient nature of MNX1’s promoter interaction, these histone marks persisted, suggesting a “hit-and-run” epigenetic remodeling mechanism. Enrichment of PBX motifs within MNX1-induced H3K4me1, H3K4me3, and ATAC-seq peaks underscores the pivotal role of the PBX family in MNX1-mediated chromatin dynamics. This was further confirmed by showing that MNX1-induced PBX1 expression could be downregulated using the Sinefungin inhibitor, a pan-methyltransferase inhibitor, that also prevent leukemia development. Our findings provide insights into how MNX1-driven epigenetic modifications are connected to its downstream targets and may offer new avenues for therapeutic intervention in t(7;12) AML.
