Posttranslational Modifications of Pyruvate Kinase M2: Tweaks that Benefit Cancer
Cancer cells rewire metabolism to meet biosynthetic and energetic demands. The characteristic increase in glycolysis, i.e., Warburg effect, now considered as a hallmark, supports cancer in various ways. To attain such metabolic reshuffle, cancer cells preferentially re-express the M2 isoform of pyruvate kinase (PKM2, M2-PK) and alter its quaternary structure to generate less-active PKM2 dimers....
متن کاملNuclear Pyruvate Kinase M2 Functional Study in Cancer Cells
Cancer cells take more glucose to provide energy and phosphoryl intermediates for cancer progression. Meanwhile, energy-provider function of mitochondria in cancer cells is disrupted. This phenomenon is so-called Warburg effect, which is discovered over eighty years ago. The detail mechanisms for Warburg effect are not well defined. How glycolytic enzymes contribute to cancer progression is not...
متن کاملTumour M2-pyruvate kinase: a gastrointestinal cancer marker.
BACKGROUND Gastrointestinal cancer tumour markers are valuable in the detection of recurrence following resection or in monitoring response to chemotherapy. CEA, CA19-9, CA-50 and CA72-4 are currently available but are nonspecific and have a low sensitivity. 'Tumour M2-pyruvate kinase' was described by Eigenbrodt around 1985. In cancers the active tetrameric form of the M2 isoenzyme of pyruvate...
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 کاملPyruvate kinase M2 at a glance.
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 understa...
