Metabolism within the tumor microenvironment and its implication on cancer progression: an ongoing therapeutic target [PDF]

open access: yes, 2018
Since reprogramming energy metabolism is considered a new hallmark of cancer, tumor metabolism is again in the spotlight of cancer research. Many studies have been carried out and many possible therapies have been developed in the last years.

Integrative Omics Defines Metabolic Biomarkers and Genetic Regulatory Mechanisms of Mortality Risk

open access: yesAdvanced Science, EarlyView.
Understanding mortality mechanisms remains a fundamental challenge. Through multi‐omics analysis of a three‐generation chicken model, are identified 45,585 mQTLs and establish a 16‐metabolite predictor of mortality. An inflammation‐growth trade‐off and evolutionarily conserved pathways involving butyrate–microbiota interactions and L‐cysteine's dual ...

Secreted Pyruvate Kinase M2 Promotes Lung Cancer Metastasis through Activating the Integrin Beta1/FAK Signaling Pathway

open access: yesCell Reports, 2020
Summary: Cancer cell-derived secretomes have been documented to play critical roles in cancer progression. Intriguingly, alternative extracellular roles of intracellular proteins are involved in various steps of tumor progression, which can offer ...

Pyruvate kinase M2-specific siRNA induces apoptosis and tumor regression [PDF]

open access: yes, 2011
Online supplemental material is available at http://www.jem.org/cgi/content/full/jem.20111487/DC1.The development of cancer-specific therapeutics has been limited because most healthy cells and cancer cells depend on common pathways. Pyruvate kinase (PK)

PKM2 regulates Gli1 expression in hepatocellular carcinoma

open access: yesOncology Letters, 2014
Hedgehog (Hh) signaling and the pyruvate kinase isoenzyme M2 (PKM2 or M2-PK) are often involved in tumorigenesis and growth. Aberrant activation of Hh signaling is found in a variety of malignancies. In tumor cells, PKM2 determines whether glucose is used for the synthesis of cellular building blocks or the production of lactate for energy regeneration;

Forsythoside E Alleviates Liver Injury by Targeting PKM2 Tetramerization to Promote Macrophage M2 Polarization

open access: yesAdvanced Science, EarlyView.
Here, the study shows for the first time that Forsythoside E (FE) can promote PKM2 tetramerization by binding to its K311 site. Furthermore, it induces metabolic reprogramming of macrophages and inhibits NLRP3 expression. Finally, it can alleviate sepsis‐induced liver injury by promoting M2 anti‐inflammatory polarization.

HSP90 promotes cell glycolysis, proliferation and inhibits apoptosis by regulating PKM2 abundance via Thr-328 phosphorylation in hepatocellular carcinoma

open access: yesMolecular Cancer, 2017
Background Heat shock protein 90 (HSP90) functions as a well-known onco-protein to regulate protein conformation, stability and degradation. Pyruvate kinase M2 (PKM2), a critical regulator of the metabolism, growth and metastasis of cancer cells, has ...

One-carbon metabolism in cancer [PDF]

open access: yes, 2017
Cells require one-carbon units for nucleotide synthesis, methylation and reductive metabolism, and these pathways support the high proliferative rate of cancer cells.

Differentiated T Lymphocytes and Cancer Cell Mitochondrial Metabolism to Enhance Radioimmunotherapy by a Biomimetic Nanozyme System

open access: yesAdvanced Science, EarlyView.
T cell membrane‐coated MgCO3/Fe‐CD nanozyme loaded with TEPP‐46 (TFMP) enhances breast cancer radioimmunotherapy by reprogramming mitochondrial metabolism in T cells and tumors. It targets PD‐L1, converts H2O2 into ROS, neutralizes acidity, and releases Mg2⁺/TEPP‐46 to boost T cell activation.

2-Oxo-N-aryl-1,2,3,4-tetrahydroquinoline-6-sulfonamides as activators of the tumor cell specific M2 isoform of pyruvate kinase [PDF]

open access: yes, 2011
Compared to normal differentiated cells, cancer cells have altered metabolic regulation to support biosynthesis and the expression of the M2 isozyme of pyruvate kinase (PKM2) plays an important role in this anabolic metabolism.
