Dual roles of PKM2 in cancer metabolism [PDF]
Cancer cells have distinct metabolism that highly depends on glycolysis instead of mitochondrial oxidative phosphorylation alone, known as aerobic glycolysis. Pyruvate kinase (PK), which catalyzes the final step of glycolysis, has emerged as a potential regulator of this metabolic phenotype.

Shmt2: a stat3 signaling new player in prostate cancer energy metabolism [PDF]
Prostate cancer (PCa) is a multifactorial disease characterized by the aberrant activity of different regulatory pathways. STAT3 protein mediates some of these pathways and its activation is implicated in the modulation of several metabolic enzymes.

PKM2 functions as a histone kinase [PDF]
In the presence of oxygen, most differentiated cells generate the energy needed for cellular processes primarily by metabolizing glucose to carbon dioxide by oxidation of glycolytic pyruvate in the mitochondrial tricarboxylic acid cycle. When oxygen becomes limited, differentiated cells produce large amounts of lactate.

Revisiting glucose metabolism in cancer: lessons from a PKM knock-in model
Isoform selection of pyruvate kinase M (PKM), a glycolytic enzyme, influences fates of glucose-derived carbons in cellular metabolic networks. We recently developed novel mouse lines to study PKM isoform function and identified PKM1 as a potential target

PKM2 is not required for colon cancer initiated by APC loss
Background Cancer cells express the M2 isoform of the glycolytic enzyme pyruvate kinase (PKM2). PKM2 expression is not required for some cancers, and PKM2 loss can promote cancer progression; however, PKM2 has been reported to be essential in other tumor

The M2 isoform of pyruvate kinase, highly expressed in tumor cells, is known to engage a feed forward loop with the glycolysis master transcription factor HIF-1α. Gao and co-authors recently showed that dimeric PKM2 localizes to the nucleus in highly proliferating cancer cells, where it regulates in vivo growth by acting as a protein kinase and ...

Pyruvate kinase M2 (PKM2) links metabolic and inflammatory dysfunction in atherosclerotic coronary artery disease; however, its role in oxidized LDL (Ox-LDL)-induced macrophage foam cell formation and inflammation is unknown and therefore was studied. In

Please Keep Me 2uned to PKM2 [PDF]
In this issue of Molecular Cell, Keller et al. (2014) found that binding of the metabolite SAICAR to PKM2 induces the protein kinase activity of an enzyme normally designed to terminate the glycolytic pathway.

Structural insight into mechanisms for dynamic regulation of PKM2 [PDF]
Pyruvate kinase isoform M2 (PKM2) converts phosphoenolpyruvate (PEP) to pyruvate and plays an important role in cancer metabolism. Here, we show that post-translational modifications and a patient-derived mutation regulate pyruvate kinase activity of PKM2 through modulating the conformation of the PKM2 tetramer.
