Decades of studies have shown that epigenetic alterations play a significant role on cancer development both in vitro and in vivo. However, considering that many cancers harbor mutations at epigenetic modifier genes and that transcription factor-mediated gene regulations are tightly coupled with epigenetic modifications, the majority of epigenetic alterations in cancers could be the consequence of the dysfunction or dysregulation of epigenetic modifiers caused by genetic abnormalities. Therefore, it remains unclear whether bona fide epigenetic abnormalities have causal roles on cancer development. Reprogramming technologies enable us to actively alter epigenetic regulations while preserving genomic information. Taking advantage, recent studies have provided in vivo evidence for the significant impact of epigenetic abnormalities on the initiation, maintenance and progression of cancer cells.
