Hi-C Analysis to Identify Genome-Wide Chromatin Structural Aberration in Cancer

Hi-C is a method that analyzes genome-wide chromatin structure using next-generation sequencer. Chromatin structure is crucial for regulating transcription or replication, and Hi-C has revealed the hierarchical chromatin structures, such as loop, domain , and compartment structures. Aberrant alteration of these structures causes disease, and a number of structural aberrations in cancer cells have been reported recently. Besides, Hi-C can identify chromosome rearrangements that frequently occurred in cancer. Therefore, Hi-C is a powerful technique to analyze epigenomic and genomic aberrations in tumorigenesis. Here we will introduce the basic protocol of Hi-C in experimental and analytical aspects.
