Super-enhancer landscape profiling in primary colorectal carcinoma

ABSTRACT: Purpose: Examine H3K27ac enhancer and super-enhancer landscape differences between primary colorectal carcinoma and adjacent normal mucosa towards the identification of novel downstream targets. Methods: H3K27ac ChIP-seq and RNA-seq were performed on fresh primary colorectal carcinoma samples and normal colonic mucosa, from human patient samples. Results: We identified 2026 total super-enhancers in our cohort, between primary colorectal and normal mucosa. We quantified differences in H3K27ac signal within this space, between tumor and normal, and identified putative downstream target genes through integration with sample matched RNA-seq using a positive linear correlation model to identifty putative target genes.

Enhancer Mapping in Chronic Lymphocytic Leukemia

Project description:<p>In this study we profile the epigenomic enhancer landscapes of CLL B cells (CD19+/CD5+) harvested from peripheral blood of patients from our Center. Included are results of ChIPseq profiling using chromatin immunoprecipitation of the enhancer histone mark H3K27ac (acetylated lysine 27 on histone H3), and open chromatin profiles using ATAC-seq (assay for transposase accessible chromatin). These profiles are used to define the global enhancer and super enhancer landscape of CLL B cells, and to derive active transcription factor networks associated with this disease. Also included are H3K27ac ChIP-seq and ATAC-seq datasets for non-CLL B cells obtained from the peripheral blood of normal adult donors.</p>

Single cell 3' RNA sequencing of 23 Korean colorectal cancer patients

Project description:For the understanding intrinsic cancer cell signatures and the surrounding microenviroment, we provide single-cell 3' RNA sequencing dataon 63,689 cells from 23 CRC patients with 23 primary colorectal cancer and 10 matched normal mucosa samples. Analysis of primary colorectal cancer and normal mucosa samples depicts a comprehensive cellular landscape of colorectal cancer and potential cellular interaction, which would be a valuable resource for the development of therapeutic strategies.

Enhancer profiling of glioblastoma uncovers core oncogenic dependency and therapeutic opportunity [RNA-seq]

Project description:Here, by mapping H3K27ac deposition, we analyze the active regulatory landscapes across primary GBM biopsies, normal brain tissues, and cell line counterparts. Analysis of differentially regulated enhancers, especially super-enhancers between GBM and normal brain tissues, as well as among GBM samples with matched RNA-sequencing data, uncovered unrecognized layers of oncogenic core transcriptional dependency and inter-tumor heterogeneity. Moreover, we demonstrate the functional relevance of leading candidates of super-enhancer-driven transcriptional factors, long non-coding RNAs, and druggable targets in GBM. Through profiling of transcriptional enhancers, our integrative study provides clinically relevant insights into GBM molecular classification, pathogenesis, and therapeutic innovations.
