Epigenetic modifications and cancer

kouzarides 2013

Do chromatin and RNA modifications offer therapeutic targets? DNA exists in the cell nucleus wrapped around histone proteins to form chromatin, a structure that must be navigated by the transcriptional machinery in order to ‘read’ the genetic code. The DNA and histones are decorated with many types of covalent chemical modifications, which can affect transcription and other cellular processes. In addition, non-coding RNAs that regulate chromatin function can be similarly chemically modified.

Our lab is involved in characterising the pathways that mediate DNA, RNA and histone modifications. We try to understand the cellular processes they regulate, their mechanism of action and their involvement in cancer.

We recently identified a novel modification of histones, methylation of glutamine, and showed that it regulates transcription; a different histone modification, citrullination, was shown to have a role in pluripotency; a novel RNA methyltransferase (BCDIN3D) was shown to be involved in cancer; and a small-molecule epigenetic inhibitor, I-BET, was shown to displace BET proteins from leukaemia genes and to be effective against MLL-leukaemia. I-BET is currently in clinical trials.
