PKM2 in carcinogenesis and oncotherapy
Tumor cell metabolism is characterized by abundant glucose consumption and aerobic glycolysis. And pyruvate kinase M2 (PKM2) plays a decisive role in glycolysis, significantly contributing to the Warburg effect, tumor growth, angiogenesis, cell division, metastasis and apoptosis.

Nuclear PKM2 regulates the Warburg effect [PDF]
Pyruvate kinase is a rate-limiting glycolytic enzyme. The PKM1 and PKM2 isoforms result from mutually exclusive alternative splicing of the PKM pre-mRNA. PKM2 rather than PKM1 regulates the Warburg effect and tumorigenesis by poorly understood mechanisms.

STAT3, a hub protein of cellular signaling pathways, is triggered by β-hexaclorocyclohexane [PDF]
Background: Organochlorine pesticides (OCPs) are widely distributed in the environment and their toxicity is mostly associated with the molecular mechanisms of endocrine disruption.

PKM2: A gatekeeper between growth and survival [PDF]
Pyruvate kinase catalyzes the transfer of a high-energy phosphate group from phosphoenol pyruvate (PEP) to generate pyruvate and ATP, a reaction that is the rate-limiting step of the glycolytic pathway. The PKM1 alternatively-spliced isoform is ubiquitously expressed whereas the PKM2 isoform is normally highly expressed only in embryos and ...

Targeting Glycolysis with Epigallocatechin-3-Gallate Enhances the Efficacy of Chemotherapeutics in Pancreatic Cancer Cells and Xenografts. [PDF]
Pancreatic cancer is a complex disease, in need of new therapeutic approaches. In this study, we explored the effect and mechanism of action of epigallocatechin-3-gallate (EGCG), a major polyphenol in green tea, alone and in combination with current ...

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.

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.

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.

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.

FOXM1D potentiates PKM2‐mediated tumor glycolysis and angiogenesis [PDF]
Tumor growth, especially in the late stage, requires adequate nutrients and rich vasculature, in which PKM2 plays a convergent role. It has been reported that PKM2, together with FOXM1D, is upregulated in late‐stage colorectal cancer and associated with metastasis; however, their underlying mechanism for promoting tumor progression remains elusive ...
