Here we propose GEM-FISH, a method for reconstructing the 3D models of chromosomes through systematically integrating both Hi-C and FISH data with the prior biophysical knowledge of a polymer model. Comprehensive tests on a set of chromosomes, for which both Hi-C and FISH data are available, demonstrate that GEM-FISH can outperform previous chromosome structure modeling methods and accurately capture the higher order spatial features of chromosome conformations. Moreover, our reconstructed 3D models of chromosomes revealed interesting patterns of spatial distributions of super-enhancers which can provide useful insights into understanding the functional roles of these super-enhancers in gene regulation. © 2019, The Author(s).enCC BY 4.0 (Attribution)©2019 The Authorshttp://creativecommons.org/licenses/by/4.0/ChromosomesGene expressionPolymersThree-dimensional modelingChromatinFinite element methodFluorescence in situ hybridizationThree dimensional imagingCell linesComputer simulationGeneticsHuman genomearticleAbbas, A., X.
