Histone acetylation role

WebbL’acétylation est associée à une activation de la transcription et est facilement réversible grâce à l’action des histones désacétylases (HDAC). La méthylation, quant à elle, peut s’effectuer soit sur des lysines soit sur des arginines et peut consister en l'ajout d'un, de deux ou de trois groupements méthyls. WebbN2 - Acetylation and deacetylation of histone and several non-histone proteins are the two important processes amongst the different modes of epigenetic modulation that are involved in regulating cancer initiation and development. Abnormal expression of histone deacetylases (HDACs) is often reported in various types of cancers.
