Nuclear translocation of the tumor marker pyruvate kinase M2 induces programmed cell death.
Cancer cells often fail to respond to stimuli that normally activate their intrinsic apoptotic machinery. Moreover, they are able to adapt to hypoxia by changing their glycolytic rate. Pyruvate kinase (PK) is a rate-limiting enzyme in glycolysis that is converted to a less active dimer form of PKM2 isoenzyme during oncogenesis. Here, we show that both somatostatin and the structural analogue TT...

متن کاملPyruvate kinase M2-specific siRNA induces apoptosis and tumor regression
The development of cancer-specific therapeutics has been limited because most healthy cells and cancer cells depend on common pathways. Pyruvate kinase (PK) exists in M1 (PKM1) and M2 (PKM2) isoforms. PKM2, whose expression in cancer cells results in aerobic glycolysis and is suggested to bestow a selective growth advantage, is a promising target. Because many oncogenes impart a common alterati...
متن کاملExtracellular Pyruvate Kinase M2 regulates tumor angiogenesis
Pyruvate kinase M2 (PKM2) has been studied for decades on its role in cancer metabolism. Re-cently, PKM2 is highlighted again for its new function: promoting gene transcription by acting as a pro-tein kinase. Moreover, the PKM2 levels in patient circulation have been used as a diagnostic marker formany types of cancers. However, it remains unclear whether PKM2 in blood circulati...
متن کاملTumor M2 pyruvate kinase: a tumor marker and its clinical application in gastrointestinal malignancy.
Proliferating cells, in particular tumor cells, express a dimeric isoenzyme of pyruvate kinase, termed Tumor M2 pyruvate kinase. In the last few years, much attention has been paid to this novel tumor marker that can be determined in EDTA-plasma and in the feces. It has been used in diagnosis and surveillance of a variety of malignant diseases. As compared with the established tumor markers, Tu...
