Project description:Primary human foreskin fibroblasts (HFF) were infected with wild-type simplex virus 1 (HSV-1) strain 17 at a multiplicity of infection (MOI) of 10. ATAC-seq libraries were prepared starting with 50,000 cells per condition following the protocol described by Buenrostro et al., Nature Methods 2013
Project description:Chromatin immunoprecipitation coupled with tagmentation followed by next-generation sequencing (ChIPmentation-seq) for histone H3 lysine 4 trimethylation (H3K4me3) was performed in human primary fibroblasts. H3K4me3 is a mark of active promoters and was used to identify open, transcriptionally active chromatin in primary dermal fibroblasts isolated from healthy donors.
Project description:Bulk ATAC-seq was performed on fibroblasts from 8 different healthy mouse tissues such as bone, epididymal and inguinal fat pads, omentum, liver, lung and lymph node. This data was used to examine tissue specific chromatin landscapes in fibroblasts.
Project description:We have obtained fibroblast cultures from old adult human donors, including Alzheimer patients. The fibroblasts were reprogrammed into directly induced neurons (iNs) to serve as an adult-like and age-equivalent model for aging and neurodegeneration. We also generated iPSCs and rejuvenated iPSC-derived induced neurons from a subset of the same cohort as controls. The cells were analyzed using several assays, including mRNA-Seq, ATAC-Seq and DNA methylation EPIC array analysis.
Project description:We report the application of the assay for transposase-accessible chromatin using sequencing (ATAC-seq) for the profiling of open chromatin human primary lung cell types implicated in lung disease pathology, such as chronic obstructive pulmonary disease. We generated chromatin accessibility profiles for human primary bronchial epithelial cells, small airway epithelial cells, alveolar type II pneumocytes, and lung fibroblasts using Omni-ATAC-seq. We further profiled open chromatin in a commonly used bronchial epithelial cell line (16HBE14o-) to evaluate the correlation with primary cell profiles and confirm the technical improvements using Omni-ATAC-seq vs Fast-ATAC-seq. We used these profiles to evaluate the enrichment of COPD risk variants in lung-specific open chromatin regions (OCRs) and generated cell type-specific regulatory predictions for >6,500 variants corresponding to 82 COPD GWAS loci.
Project description:ATAC-seq of 79 primary samples obtained from human acute leukemias, namely AML, T-ALL and mixed myeloid/lymphoid leukemias with CpG Island Methylator Phenotype (CIMP). Moreover, ATAC-seq of CD34+ HSPCs from 3 healthy donors are included. ATAC-seq was performed as described (Buenrostro et al., 2013) with a modification in the lysis buffer to reduce mitochondrial DNA contamination. Due to patient confidentiality considerations, the raw data files for this dataset have been deposited to the EGA controlled-access archive under the accession numbers EGAS00001007094 (study); EGAD00001011050 (dataset).
