PKM2 expression is also up-regulated by Never in mitosis gene A-related kinase 2 (NEK2). NEK2 combines with hnRNP1 or hnRNP2 and promotes the release of exon 10 and activates PKM2. The silencing of NEK2 down-regulates the PKM2 expression ( 2 ).
This gene encodes a protein involved in glycolysis. The encoded protein is a pyruvate kinase that catalyzes the transfer of a phosphoryl group from phosphoenolpyruvate to ADP, generating ATP and pyruvate. PKM2 is regulated on several cellular levels, including gene expression, alternative splicing and post-translational modification. In addition, PKM2 is regulated by key metabolic intermediates and interacts with more than twenty different proteins.
with nuclear PKM2 expression levels, glioma malig-nancy grades, and prognosis. These findings high-light the role of PKM2 as a protein kinase in its nonmetabolic functions of histone modification, which is essential for its epigenetic regulation of gene expression and tumorigenesis. INTRODUCTION

Pkm2 gene expression

The expression of PKM2 has been shown to be influenced by a spectrum of signaling pathways that are stimulated by tumor microenvironment (hypoxia and nutrient status), aberrant oncogenic mutations, growth factors, and hormones. These signaling pathways, through the network of transcription factors, regulate PKM2 expression.


In Specific Aim 1, we will further elucidate the mechanisms underlying PKM2-mediated gene transcription and identify PKM2-regulated expression of genes in cancer cells by genome-wide screening. In Specific Aim 2, we will elucidate the mechanisms underlying PKM2-regulated chromosome segregation.

Docker push multiple tagsOct 01, 2012 · PKM2 also can directly regulate gene expression, as a recent study has shown that PKM2 translocates to the nucleus, forms a complex with β-catenin, and binds the cyclin D1 (CCND1) and MYC promoters to promote transcription in response to epidermal growth factor receptor (EGFR) activation. Dec 27, 2016 · PKM2 and other key regulators of Warburg effect positively correlate with CD147 (EMMPRIN) gene expression and predict survival in multiple myeloma gene expression was induced in the EMT condition, with pref-erential expression of PKM2 compared with PKM1 (Fig. 1D). Western blot analysis indicated that the induction of EMT resulted in decreased CDH1 expression, increased VIM expres-sion, and up-regulated PKM2 (Fig. 1E). We confirmed that the

In addition to regulation of gene expression, the existence of PKM2 in exosomes opens a new venue to study the potential role of this glycolytic enzyme in cell-cell communication and extracellular signal initiation. The expression of PKM2 has been shown to be influenced by a spectrum of signaling pathways that are stimulated by tumor microenvironment (hypoxia and nutrient status), aberrant oncogenic mutations, growth factors, and hormones. These signaling pathways, through the network of transcription factors, regulate PKM2 expression. In Specific Aim 1, we will further elucidate the mechanisms underlying PKM2-mediated gene transcription and identify PKM2-regulated expression of genes in cancer cells by genome-wide screening. In Specific Aim 2, we will elucidate the mechanisms underlying PKM2-regulated chromosome segregation.

Bluemlein et al. (2011) found that expression of PKM2 dominated over PKM1 in malignant tumors, benign tumors, and cancer cell lines. Total PKM expression was generally elevated in cancers compared with controls, but there was no evidence for isoform switching from PKM1 to PKM2 with cancer. PKM2 Antibodies . PKM2 is a pyruvate kinase that catalyzes the production of phosphoenolpyruvate from pyruvate and ATP. PKM2 has been shown to interact with thyroid hormone, and thus may mediate cellular metabolic effects induced by thyroid hormones. « hide 10 20 30 40 50 mskphseagt afiqtqqlha amadtflehm crldidsppi tarntgiict 60 70 80 90 100 igpasrsvet lkemiksgmn varlnfshgt heyhaetikn vrtatesfas 110 120 130 140 150 dpilyrpvav aldtkgpeir tglikgsgta evelkkgatl kitldnayme 160 170 180 190 200 kcdenilwld yknickvvev gskiyvddgl islqvkqkga dflvteveng 210 220 230 240 250 gslgskkgvn lpgaavdlpa vsekdiqdlk fgveqdvdmv fasfirkasd 260 270 280 290 300 ...

PrimePCR™ PreAmp for SYBR® Green Assay: PKM2, Human Reaction: 400 reactions Gene-specific PCR primers for the unbiased preamplification of small quantities of cDNA for subsequent use in downstream gene expression analysis.

PKM2 and metabolic gene expression profiles. a The expression levels of PKM2 in low-PKM2 (< 11.25) patients (light blue) were similar to the controls (gray), whereas the expression levels of PKM2 in high-PKM2 (≥ 11.25) patients (red) were significantly higher than the controls.

Hall county sheriff warrantswith nuclear PKM2 expression levels, glioma malig-nancy grades, and prognosis. These findings high-light the role of PKM2 as a protein kinase in its nonmetabolic functions of histone modification, which is essential for its epigenetic regulation of gene expression and tumorigenesis. INTRODUCTION и In addition to regulation of gene expression, the existence of PKM2 in exosomes opens a new venue to study the potential role of this glycolytic enzyme in cell-cell communication and extracellular signal initiation.

  • Vw golf mk4 door panel removalOn the contrary, PKM2 expression failed to be significantly modulated by WTp53 and its phosphorylated form on Tyr105 is significantly increased after WTp53 knockdown (Fig. 1). Overall, these data let us to hypothesize that the stimulation of mTOR/PKM2 pathway is aberrantly induced by GOF mutant isoforms of p53. Sep 14, 2018 · PKM2 gene expression, and PKM2 in turn interacts with the HIF-1 α subunit and stimulates its transactivation in a feedback loop [ 30 ]. In the present study, we explored the effects of Unlike the PKM2 tetramer (the active form of PKM2 in the cytoplasm), which has high glycolytic activity, the PKM2 dimer (the active form of PKM2 in the nucleus) functions as a protein kinase and promotes tumorigenesis and progression by regulating gene expression .
