Decitabine treatment reveals a functional role of DNA hypomethylation in organising enhancer-promoter interactions [Promoter Capture Hi-C]

Project description:DNA methylation is one of the most important epigenetic marks and changes in DNA methylation patterns have been associated with many different types of cancer. Recently, three-dimensional (3D) genome organisation has been demonstrated to play a fundamental role in gene regulation. Determining the interplay between DNA methylation and 3D chromatin structure and function is challenging due to the extreme complexity of epigenetic regulation. To study the impact of DNA methylation on 3D genome organization, we performed a time-course of Decitabine treatment in tamoxifen-resistant MCF7 (TAMR) cells. Decitabine was applied daily for 7 days, followed by “recovery” up to 28 days and DNA methylation (EPIC), gene expression (RNA-seq) and promoter-enhancer interactions (PCHi-C) were assessed on day 7 post-Decitabine- and Vehicle-treatment and day 28 “Recovery” and Vehicle treatment in duplicate. Our data revealed a functional link between DNA hypomethylation at distal enhancer regions, enhancer-promoter interactions, and gene regulation.

Promoter Capture Hi-C of mouse ESC and TSC

Project description:Chromatin organisation of trophoblast stem cells (TSC) were compared with that of embryonic stem cells (ESC). The method enriches Hi-C libraries, to detect promoter interactions at restriction fragment level. We prepared Hi-C libraries from TSC and ESC (serum grown) samples and enriched them with a promoter capture bait system that captures ~22.000 promoters. Promoter interactions were then analysed using the GOTHiC pipeline.

Promoter capture Hi-C of CD34+ haematopoietic stem cells

Project description:CD34+ heamatopoietic stem cells were isolated from the bone marrow of two healthy donors undergoing total hip replacement. Promoter capture Hi-C (PCHi-C) was performed on these cells using the protocol according to Mifsud et al. 2015, with the exception that ligation was performed in situ, and a slightly modified bait capture set was used. Bait positions in hg19 are included as an additional file.
