A prostate cancer chromatin interaction map


ABSTRACT: A high-resolution 3D epigenomic map reveals insights into the creation of the prostate cancer transcriptome Prostate cancer (PCa) is the leading cancer among men in the United States. To understand gene regulation in 3D, chromatin interactions in prostate cancer cell is measured using in situ Hi-C. To better understand the impact of chromatin structure on regulation of the prostate cancer transcriptome, we developed high-resolution chromatin interaction maps in normal and prostate cancer cells using in situ Hi-C. By combining the in situ Hi-C data with active and repressive histone marks, CTCF binding sites, nucleosome-depleted regions, and transcriptome profiling, we identified topologically associating domains that changed in size and epigenetic states between normal and prostate cancer cells. Moreover, we identified normal and prostate cancer-specific enhancer-promoter loops and involved transcription factors. This creation of 3D epigenomic maps will enable a better understanding of prostate cancer biology and mechanisms of gene regulation.
