Acetylation of MAT IIα represses tumour cell growth and is decreased in human hepatocellular cancer

Folate plays an essential role in dividing cells and is regulated by methionine adenosyltransferase (MAT), where a switch from MAT Iα to MAT IIα expression seems to promote liver cancer progression. Here the authors demonstrate that MAT IIα stability is regulated by acetylation and this regulation is important for tumour growth.
