[The role of three-dimensional chromatin structure changes in tumor progression].

The human genome is not a linear structure, but a three-dimensional structure through complex folding and assembly. Chromosome structure capture technology can detect the three-dimensional construction of chromatin. Hi-C sequencing data of various tumors indicate that the chromatin topology associated domains changed during tumor progression and is related to copy number variation. In addition, transformation of the genomic compartment is related to gene expression. However, current researches on three-dimensional structures of tumoral chromatin are still in the stage of exploration, and some conclusions are too superficial to be applied to the clinic immediately, which requires further study.
