Abstract
Chromosome conformation capture (3C) methods are central to understanding the link between nuclear structure and function, and the physical interactions between distal regulatory elements and promoters. However, no one method is appropriate to address all biological questions, as each variant differs markedly in resolution, reproducibility, throughput and biases. A thorough appreciation of the strengths and weaknesses of each technique is critical when choosing the correct method for a specific application or for gauging how best to interpret different sources of data. In addition, the analysis method must be carefully considered, as this choice can profoundly affect the output. In this Review, we describe and compare the different available 3C-based approaches, with a focus on the analysis of mammalian genomes.

Supplementary Figure 1 Chromatin, 4C and NG Capture-C data for the alpha globin locus in mouse erythroid cells.
The DNaseI hypersensitivity track (green), marking open chromatin, is shown at the top. Below are ChIP-seq profiles for H3K4me3, H3K4me1 and CTCF, that highlight promoters, enhancers and CTCF binding sites respectively (Hughes et al., 2014).
The raw and normalized 4Cseq profiles are shown below (van der Werken et al., 2012). The NG Capture-C profiles are an average of 4 replicates in erythroid cells and 3 ES cell replicates. The bottom track shows significant differences (-log10 p value) between the interaction profiles when the gene is active (erythroid cells) and inactive (ES cells). The data can be analysed by DESeq2, which is used for comparative analysis of several different types of count based sequencing data, particularly RNAseq.
Supplementary Figure 2 Chromatin data for the Sox2 locus in mouse ES cells.
The DNaseI hypersensitivity track, marks open chromatin and nonspecifically highlights regulatory elements. Below are ChIP-seq profiles for H3K4me1, H3K4me3, mediator (Med1) Oct-4, Nanog, and CTCF, which allow the DNAseI hypersensitive sites to be defined further.
A cluseter of hypersensitive sites 85-111kb from the promoter of the gene are defined as a superenhancer in ES cells by Whyte et al., 2013. However, the gene has several other cell type specific regulatory, which extend nearly 1Mb away from the promoter. These tend to be with CTCF sites (highlighted in purple) although there is an additional element potential regulatory element bound by Nanog and Oct4 (HS+683).
ES cell data: DNAseI-seq (ENCODE UW); ChIP-seq H3K4me1 and H3K4me3 (ENCODE/LICR); CTCF (LICR GSM918748); MED1 (Young lab GSM1038259), Sox2 (Young lab GSM1082341), Nanog (Young lab GSM1082342), Oct4 (Young lab GSM1082340)
