Targeting DNA methylation.
Two nucleoside inhibitors of DNA methylation, azacitidine and decitabine, are now standard of care for the treatment of the myelodysplastic syndrome, a deadly form of leukemia. These old drugs, developed as cytotoxic agents and nearly abandoned decades ago were resurrected by the renewed interest in DNA methylation. They have now provided proof of principle for epigenetic therapy, the final cha...
متن کاملTargeting DNA methylation to the genome.
Proving direct relationships between DNA alterations and phenotypes is challenging. For epigenetics researchers, linking DNA methylation with human disease is no exception. But Patrick Lo looks at how two researchers are developing new methods to try to trace the road from DNA methylation to human biology.
متن کاملSpecific targeting of cytosine methylation to DNA sequences in vivo
Development of methods that will allow exogenous imposition of inheritable gene-specific methylation patterns has potential application in both therapeutics and in basic research. An ongoing approach is the use of targeted DNA methyltransferases, which consist of a fusion between gene-targeted zinc-finger proteins and prokaryotic DNA cytosine methyltransferases. These enzymes however have so fa...
متن کاملDNA Methylation Targeting: The DNMT/HMT Crosstalk Challenge
Chromatin can adopt a decondensed state linked to gene transcription (euchromatin) and a condensed state linked to transcriptional repression (heterochromatin). These states are controlled by epigenetic modulators that are active on either the DNA or the histones and are tightly associated to each other. Methylation of both DNA and histones is involved in either the activation or silencing of g...
متن کاملDNA Methylation and Its Role in the Development of Leukemia
Epigenetic changes play an essential role in cancer pathogenesis. It has been established by next-generation sequencing that more than 50% of the human cancers carry mutations in mechanisms involved in the organization of the chromatin and epigenetic regulations. DNA methylation is among the most common epigenetic changes in leukemia. In contrast to DNA mutations which are passively inherited f...
