Chromosome conformation capture technologies and their impact in understanding genome function

Résumé

It has been more than a decade since the first chromosome conformation capture (3C) assay was described. The assay was originally devised to measure the frequency with which two genomic loci interact within the three-dimensional (3D) nuclear space. Over time, this method has evolved both qualitatively and quantitatively, from detection of pairwise interaction of two unique loci to generating maps for the global chromatin interactome. Combined with the analysis of the epigenetic chromatin context, these advances led to the unmasking of general genome folding principles. The evolution of 3C-based methods has been supported first by the revolution in ChIP and then by sequencing-based approaches, methods that were primarily tools to study the unidimensional genome. The gradual improvement of 3C-based methods illustrates how the field adapted to the need to gradually address more subtle questions, beginning with enquiries of reductionist nature to reach more holistic perspectives, as the technology advanced, in a process that is greatly improving our knowledge on genome behavior and regulation. Here, we describe the evolution of 3C and other 3C-based methods for the analysis of chromatin interactions, along with a brief summary of their contribution in uncovering the significance of the three-dimensional world within the nucleus. We also discuss their inherent limitations and caveats in order to provide a critical view of the power and the limits of this technology.
