Structural basis of PKM2 regulation [PDF]
Alterations in cell metabolism are a characteristic of many cancers. Cancer cells are metabolically rewired to support their rapid growth (Kim and Dang, 2006; Vander Heiden et al., 2009). The best-characterized metabolic phenotype observed in tumor cells is aerobic glycolysis, also known as the Warburg effect, which is a shift of ATP generation from ...

PKM2 and the Tricky Balance of Growth and Energy in Cancer [PDF]
In this issue of Molecular Cell, Lv et al. (2011) identify a novel feedback mechanism in which increased glycolysis induces the acetylation and chaperone-mediated autophagic degradation of the glycolytic regulator PKM2, revealing a novel metabolic feedback loop that drives tumor growth.

Lack of Evidence for PKM2 Protein Kinase Activity [PDF]
The role of pyruvate kinase M2 (PKM2) in cell proliferation is controversial. A unique function of PKM2 proposed to be important for the proliferation of some cancer cells involves the direct activity of this enzyme as a protein kinase; however, a detailed biochemical characterization of this activity is lacking. Using [(32)P]-phosphoenolpyruvate (PEP)

PARP14 promotes the warburg effect in hepatocellular carcinoma by inhibiting JNK1-dependent PKM2 phosphorylation and activation [PDF]
Most tumour cells use aerobic glycolysis (the Warburg effect) to support anabolic growth and evade apoptosis. Intriguingly, the molecular mechanisms that link the Warburg effect with the suppression of apoptosis are not well understood.

PKM2 promotes reductive glutamine metabolism
Pyruvate kinases M (PKM), including the PKM1 and PKM2 isoforms, are critical factors in glucose metabolism. PKM2 promotes aerobic glycolysis, a phenomenon known as " the Warburg effect". The purpose of this study was to identify the roles of PKM2 in regulating cellular metabolism.The CRISPR/Cas9 system was used to generate the PKM-knockout cell model ...

PKM2 dephosphorylation by Cdc25A promotes the Warburg effect and tumorigenesis [PDF]
AbstractMany types of human tumour cells overexpress the dual-specificity phosphatase Cdc25A. Cdc25A dephosphorylates cyclin-dependent kinase and regulates the cell cycle, but other substrates of Cdc25A and their relevant cellular functions have yet to be identified.

PKM2-mediated metabolic reprogramming of microglia in neuroinflammation. [PDF]
Abstract Microglia, the resident immune cells of the central nervous system, undergo metabolic reprogramming during neuroinflammation, playing a crucial role in the pathogenesis of neurological disorders such as Parkinson’s disease. This review focuses on Pyruvate Kinase M2 (PKM2), a key glycolytic enzyme, and its impact on microglial ...

Altered mitochondrial function and energy metabolism is associated with a radioresistant phenotype in oesophageal adenocarcinoma [PDF]
Neoadjuvant chemoradiation therapy (CRT) is increasingly the standard of care for locally advanced oesophageal cancer. A complete pathological response to CRT is associated with a favourable outcome.

The Role of PKM2 in Diabetic Microangiopathy
Diabetic microangiopathy is among the most common complications affecting patients with diabetes, and includes both diabetic retinopathy (DR) and diabetic nephropathy (DKD). Diabetic microangiopathy remains a persistent threat to the health and quality of life of affected patients.
