AMPK activation counteracts cardiac hypertrophy by reducing O-GlcNAcylation

AMPK activation inhibits cardiac hypertrophy. Here the authors show that this occurs independently of previously proposed mechanisms and that AMPK controls the phosphorylation of the aminotransferase GFAT, thereby preventing cardiac hypertrophy through the reduction of protein O-GlcNAcylation.
