Mammalian target of rapamycin up-regulation of pyruvate kinase isoenzyme type M2 is critical for aerobic glycolysis and tumor growth. Therefore, pyruvate kina… PKM2 has been shown to be the cytosolic receptor for thyroid hormone (Kato et al., 1989). Several transcriptional factors have been reported to regulate the activity of the PKM promoter, which contains five putative binding sites for SP1 and SP3. Shikonin treatment inhibits glucose consumption and lactate release, and so induces tumor cell death. Plasma membrane-localized PK is sufficient to close K ATP … Glucose-stimulated increase in cytoplasmic pH precedes increase in free Ca2+ in pancreatic beta-cells. Comprehensive alpha, beta and delta cell transcriptomes reveal that ghrelin selectively activates delta cells and promotes somatostatin release from pancreatic islets. Consequently, these miRNAs mediate a switch in expression of the PKM gene from the PKM2 isoform to PKM1, which results in a reduced glycolysis rate and promotes the glucose flux into oxidative phosphorylation, consequently leading to impaired cancer cell growth (Sun et al., 2012).

"Pyruvate kinase doesn't change how much fuel comes into the cell, it just changes how that fuel is used," says Merrins. miRNAs, noncoding RNAs that bind to specific target mRNAs and promote their degradation and/or hinder their translation, provide another means for regulating PKM2 mRNA. During cytokinesis, Aurora B phosphorylates PKM2 at T45, which is required for the localization of PKM2 and its interaction with MLC2 in the contractile ring region of mitotic cells; this leads to PKM2‐mediated phosphorylation of MLC2 at Y118. ]; a Odyssey Fellowship from The University of Texas MD Anderson Cancer Center (to W.Y. While we look forward to a new year, join us as we reflect on the triumphs of the last 12 months. Genetic defects of this enzyme cause the disease known as pyruvate kinase deficiency. There are four isomeric, tissue-specific forms of Pyruvate Kinase … No evidence for a shift in pyruvate kinase PKM1 to PKM2 expression during tumorigenesis. The gene that causes pyruvate kinase deficiency is called the PKLR gene that is located on chromosome … PKM2, cancer metabolism, and the road ahead. Pyruvate kinase deficiency is inherited in an autosomal recessive fashion, which means that a child must inherit a gene with a disease-causing mutation from both parents to develop the disorder. Activation of AKT in PTEN‐deficient fatty livers results in the binding of PPARγ to PPAR response elements (PPRE) in the promoter region of both PKM and the hexokinase‐2 (HK2) gene, and contributes to liver steatosis, hypertrophy and hyperplasia (Panasyuk et al., 2012).

Glycolysis preferentially inhibits ATP-sensitive K+ channels in isolated guinea pig cardiac myocytes. mTOR inhibition reverses Akt-dependent prostate intraepithelial neoplasia through regulation of apoptotic and HIF-1-dependent pathways. Importantly, PKM2 has recently been found to translocate into the nucleus upon mitogenic and oncogenic stimulation (Lv et al., 2013; Yang et al., 2012c). This phosphorylation primes the binding of Rho‐associated protein kinase 2 (ROCK2) to MLC2 and subsequent ROCK2‐dependent MLC2 S15 phosphorylation. Both miR‐133a and miR‐133b target the PKM transcript, and these miRNAs have been found to be significantly reduced in tongue squamous cell carcinoma cells, resulting in PKM2 overexpression (Wong et al., 2008). The SUMO-E3 ligase PIAS3 targets pyruvate kinase M2. It is the last … Red cell pyruvate kinase deficiency is the most common cause of hereditary nonspherocytic hemolytic anemia. Further studies are therefore warranted to understand the distinct regulatory effects of different PKM2 activators on cells. Upon EGFR activation, activated extracellular signal‐regulated kinase 1 and 2 (ERK1/2) binds to the region that is encoded by exon 10 of PKM2 through a docking groove in ERK1/2, resulting in phosphorylation of S37 of PKM2, but not PKM1. Fructose-1,6-bisphosphate is an allosteric activator … If you have any questions or concerns, please do not hestiate to contact the Editorial Office. DOI: https://doi.org/10.1016/j.cmet.2020.10.007.

Decreased PKM2 pyruvate kinase activity has been shown to result in PEP‐dependent histidine phosphorylation and activation of phosphoglycerate mutase (PGAM1), as well as in reduced levels of PEP‐dependent ATP production; this metabolic switch might provide an alternate glycolytic pathway that decouples ATP from PEP‐mediated phosphotransfer, thereby allowing for the high rate of glycolysis to support the anabolic metabolism (Vander Heiden et al., 2010b). Shikonin and its analogs inhibit cancer cell glycolysis by targeting tumor pyruvate kinase-M2. KCl -permeabilized pancreatic islets: an experimental model to explore the messenger role of ATP in the mechanism of insulin secretion. Furthermore, a Phase II clinical trial with a peptidic inhibitor of PKM2 has been initiated to evaluate the potential of PKM2 as a therapeutic target in patients with refractory metastatic renal cell carcinoma, and encouraging results have been obtained (Porporato et al., 2011). Furthermore, in primary mouse embryonic fibroblasts in which PKM2 was deleted, PKM1 expression is upregulated and impairs nucleotide production and the ability of cells to synthesize DNA and progress the cell cycle, suggesting that an appropriate level of PKM2 expression is important for normal cell proliferation (Lunt et al., 2015). Red blood cells carry oxygen to all parts of the body. This phosphorylation leads to the recruitment of the Bub3–Bub1 complex to the outer kinetochore protein Blinkin (also known as CASC5), which acts as a receptor for Bub proteins; this regulation exerts a precise control over the kinetochore–spindle attachment and the mitotic (spindle assembly) checkpoint, and, subsequently, accurate chromosome segregation and proliferation of tumor cells (Jiang et al., 2014a). Pyruvate kinase is an enzyme found within red blood cells … In addition to its well‐known role in glycolysis, PKM2 has also been reported to be involved in other cellular functions. Our group has reported that nuclear PKM2 interacts with c‐Src‐phosphorylated β‐catenin Y333 and enhances the transactivation activity of β‐catenin, highlighting the importance of PKM2 as a transcriptional co‐activator (Yang et al., 2011) (see poster).
