New Technology Helps Reveal Inner Workings of Human Genome

Weill Cornell Medicine and New York Genome Center researchers, in collaboration with Oxford Nanopore Technologies, have developed a new method to assess on a large scale the three-dimensional structure of the human genome, or how the genome folds. The genome is the complete set of genetic instructions, DNA or RNA, enabling an organism to function.

Using this method, the researchers demonstrated that cell function, including gene expression, may be affected by groups of simultaneously interacting regulatory elements in the genome rather than pairs of these components. Their findings, published May 30 in Nature Biotechnology, may help shed light on the relationship between genome structure and cellular identity.

“Knowing the three-dimensional genome structure will help researchers better understand how the genome functions, and particularly how it encodes different cell identities,” said senior author Dr. Marcin Imieliński, associate professor of pathology and laboratory medicine and computational genomics in computational biomedicine at…
