ChIATAC is an efficient strategy for multi-omics mapping of 3D epigenomes from low-cell inputs

Abstract: Connecting genes to their cis-regulatory elements has been enabled by genome-wide mapping of chromatin interactions using proximity ligation in ChIA-PET, Hi-C, and their derivatives. However, these methods require millions of input cells for high-quality data and thus are unsuitable for many studies when only limited cells are available. Conversely, epigenomic profiling via transposase digestion in ATAC-seq requires only hundreds to thousands of cells to robustly map open chromatin associated with transcriptio… Show more

“…In order to develop a single cell method to simultaneously capture chromatin interactions and epigenomic states, we have previously established a bulk-cell dual-omic method called ChIATAC( 22 ). ChIATAC captures open chromatin loci similar to ATAC-seq( 23 ) and chromatin interactions between those loci simultaneously.…”

“…Micro‐Capture‐C (MCC) 50 and Tiled‐MCC 51 technologies, both of which are based on Micro‐C, were developed for high‐resolution chromatin interaction of specific loci. As needed, other derivative technologies centred on specific factors (e.g., TFs or histones) or specific elements (e.g., promoter or enhancer regions) were established, such as ChIA‐PET, 52 HiChIP, 53 Capture Hi‐C, 54 ChIATAC, 55 and others (Figure 2). Furthermore, the development of single‐cell Hi‐C technology allowed us to detect thousands of chromatin contacts in single cells 56 .…”

“…The number of photoconverted cells is at user discretion and can be adjusted to fit the experimental parameters. Multiple sequencing techniques are becoming readily available to produce analyses from low cell inputs [67][68][69]. These approaches provide novel sequencing feasibility to broadly define mechanistic cellular differences within smaller subpopulations.…”
