Abstract
A dynamic reorganization of epigenetic regulation takes place during cellular reprogramming. Given that reprogramming does not require changes in the underlying genome information, reprogramming technology can be used to actively modify the epigenetic regulation and thus is useful for studying the genome-epigenome relationship. Cancer cells harbor both genetic and epigenetic alterations. Although the causal role of genetic aberrations on cancer development has been well characterized by reverse genetics in vivo, the impact of epigenetic abnormalities remains to be fully understood, especially in vivo. Recent genome-wide sequencing studies have identified frequent mutations at epigenetic modifier genes, thus indicating that epigenetic alterations in cancer could be the consequence of genetic mutations. However, recent studies that utilized reprogramming technology for cancer research have demonstrated cellular context-associated epigenetic regulation that is independent of genetic mutations and plays a critical role on both the development and maintenance of cancer cells. In this review, we propose that reprogramming technology could be a powerful tool for dissecting the role of epigenetic regulation in cancer biology.
