ERK1/2-dependent phosphorylation and nuclear translocation of PKM2 promotes the Warburg effect
2012
Lu and colleagues delineate a pathway through which the PKM2 enzyme promotes aerobic glycolysis, known as the Warburg effect, in cancer cells. They show that EGFR-activated ERK phosphorylates PKM2, leading to its accumulation in the nucleus. Nuclear PKM2 subsequently promotes the c-Myc-dependent upregulation of genes involved in the Warburg effect, resulting in tumour growth.
