The long-range interactions of cis-regulatory elements (cREs) play a central role in gene regulation. cREs can be characterized as accessible chromatin sequences. However, it remains technically challenging to comprehensively identify their spatial interactions. Here, we report a new method HiCAR (Hi-C on Accessible Regulatory DNA), which utilizes Tn5 transposase and chromatin proximity ligation, for the analysis of open chromatin anchored interactions with low-input cells. By applying HiCAR in human embryonic stem cells and lymphoblastoid cells, we demonstrate that HiCAR identifies high-resolution chromatin contacts with an efficiency comparable to that of in situ Hi-C over all distances range. Interestingly, we found that the “poised” gene promoters exhibit silencer-like function to repress the expression of distal genes via promoter-promoter interactions. Lastly, we applied HiCAR to 30,000 primary human muscle stem cells, and demonstrated that HiCAR is capable of analyzing chromatin accessibility and looping using low-input primary cells and clinical samples. HiCAR utilizes Tn5 transposase and chromatin proximity ligation to capture open chromatin anchored interactions with low-input cells. It requires <10% sequencing depth of Hi-C to call high-resolution chromatin interactions. Interestingly, we found that the “poised” gene promoters exhibit silencer-like function to repress the expression of distal genes via promoter-promoter interactions.
