Hi-C Chromatin Interaction Networks Predict Co-expression in the Mouse Cortex

We studied the functional role of three dimensional conformation of the genome in the cell nucleus on gene expression regulation. Long-range chromatin interactions arise as a result of the three-dimensional (3D) conformation of chromosomes in the cell nucleus and can result in the co-localization of co-regulated genes. To assess the influence of 3D conformation on gene co-expression, we used chromatin conformation capture (Hi-C) data from the mouse cortex to build a chromatin interaction network (CIN) of genes. We show that by characterizing the topology of the CIN at different scales it is possible to accurately predict spatial co-expression between genes in the mouse cortex.
