WebIn particular, the early findings that a variety of tumor suppressor genes (TSGs) are targets of DNA hypermethylation in cancer led to the proposal of a model in which aberrant DNA methylation promotes cellular oncogenesis through TSGs silencing. However, recent genome-wide analyses have revealed that this classical model needs to be reconsidered. WebSep 7, 2024 · RNA-directed DNA methylation is a fundamental epigenetic gene silencing phenomenon almost found in all living organisms ( Wassenegger et al., 1994 ).
