Nuclear PKM2 regulates the Warburg effect [PDF]
Cell Cycle, 2013 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.

Cells, 2023 Pyruvate kinase M (PKM) 2 was described to interact with the inositol 1,4,5-trisphosphate (IP3) receptor (IP3R) and suppress its activity. To further investigate the physiological importance of the PKM2:IP3R interaction, we developed and characterized HeLa PKM2 knockout (KO) cells.

Pyruvate Kinase M2 and Cancer: The Role of PKM2 in Promoting Tumorigenesis
Frontiers in Oncology, 2020 Pyruvate kinase plays a pivotal role in regulating cell metabolism. The final and rate-limiting step of glycolysis is the conversion of Phosphoenolpyruvate (PEP) to Pyruvate, which is catalyzed by Pyruvate Kinase. There are four isomeric, tissue-specific

PKM2: A gatekeeper between growth and survival [PDF]
Cell Research, 2011 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 ...

Dual roles of PKM2 in cancer metabolism [PDF]
Acta Biochimica et Biophysica Sinica, 2013 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.

Cancer & Metabolism, 2018 Background Alternative splicing of the Pkm gene product generates the PKM1 and PKM2 isoforms of the glycolytic enzyme pyruvate kinase. PKM2 expression is associated with embryogenesis, tissue regeneration, and cancer.

Frontiers in Pharmacology, 2023 Objectives: Dimeric pyruvate kinase (PK) M2 (PKM2) plays an important role in promoting the accumulation of hypoxia-inducible factor (HIF)-1α, mediating aberrant glycolysis and inducing fibrosis in diabetic kidney disease (DKD).

Revisiting glucose metabolism in cancer: lessons from a PKM knock-in model
Molecular & Cellular Oncology, 2018 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

Signal Transduction and Targeted Therapy, 2022 Metastasis is a major cause of colorectal cancer (CRC) mortality, but its molecular mechanisms are still not fully understood. Here, we show that upregulated DDX39B correlates with liver metastases and aggressive phenotypes in CRC.
