Reprogrammed metabolism is a key feature of cancer cells. The pyruvate kinase M2
(PKM2) isoform, which is commonly upregulated in many human cancers, has been
recently shown to play a crucial role in metabolism reprogramming, gene
transcription and cell cycle progression. In this Cell Science at a glance
article and accompanying poster, we provide a brief overview of recent advances
in understanding the mechanisms underlying the regulation of PKM2 expression,
enzymatic activity, metabolic functions and subcellular location. We highlight
the instrumental role of the non-metabolic functions of PKM2 in tumorigenesis and
evaluate the potential to target PKM2 for cancer treatment.
