Glucose catabolism in liver tumors induced by c-MYC can be sustained by various PKM1/PKM2 ratios and pyruvate kinase activities

Cancer Research, 2017
Different pyruvate kinase isoforms are expressed in a tissue-specific manner, with pyruvate kinase M2 (PKM2) suggested to be the predominant isoform in proliferating cells and cancer cells. Due to differential regulation of enzymatic activities, PKM2 but

Uhrf1‐Mediated PKM2 Degradation via Ubiquitination Alleviates Inflammation and Pyroptosis in Inflammatory Bowel Disease

Advanced Science, EarlyView.
Uhrf1‐mediated PKM2 ubiquitination and degradation repressed the nuclear translocation of PKM2, and EPT served as a molecular glue capable of targeting the Uhrf1–PKM2 complex to alleviate the IBD course, suggesting that the Uhrf1–PKM2 axis was a previously unrecognized strategy for treating IBD.

Enzymatic Activity Assay Development for Pyruvate Kinase

, 2019
Pyruvate kinase (PK) is an enzyme that catalyzes the last step in the process of glycolysis. PK transfers the phosphate group from phosphoenolpyruvate to ADP, thereby generating one molecule of ATP and pyruvate.

The Cancer Cell Metabolic Reprogramming Remodels the Tumor Microenvironment: Molecular Mechanisms and Therapeutic Strategies

Advanced Science, EarlyView.
This review elucidates how cancer cell metabolic reprogramming—across glucose, lipid, amino acid, and nucleotide pathways—remodels the tumor microenvironment to suppress anti‐tumor immunity and promote immune escape. Targeting these metabolic axes offers promising strategies to overcome immunotherapy resistance and enhance cancer treatment.

Generation of a High Number of Healthy Erythroid Cells from Gene-Edited Pyruvate Kinase Deficiency Patient-Specific Induced Pluripotent Stem Cells

Stem Cell Reports, 2015
Pyruvate kinase deficiency (PKD) is a rare erythroid metabolic disease caused by mutations in the PKLR gene. Erythrocytes from PKD patients show an energetic imbalance causing chronic non-spherocytic hemolytic anemia, as pyruvate kinase defects impair ...

Apparent inhibition of pyruvate kinase by phosphocreatine and phosphoarginine

, 1979
Addition of a non-dialysable, heat-labile and acid-precipitable factor which was not absorbed on DEAE-cellulose column, could restore the sensitivity of the chromatographed muscle pyruvate kinase from Marphysa sanguinea towards phosphocreatine inhibition.

DIXDC1 Promotes Lymphatic Metastasis and Resistance to Cuproptosis in Bladder Cancer Through Mediating DLAT

Advanced Science, EarlyView.
DIXDC1 drives bladder cancer progression by binding and stabilizing DLAT. This axis enhances NEK7 and CCNE2 mRNA stability to promote proliferation and lymphatic metastasis, while limiting copper‐induced DLAT oligomerization to reduce cuproptosis sensitivity, identifying DIXDC1 as a potential target linking metastasis with cuproptosis resistance ...

AARS1‐Mediated H3K27 Lactylation Rewires Glycolysis to Sustain Aggressive and Recurrent Bladder Cancer

Advanced Science, EarlyView.
AARS1 drives PI3K–AKT–mTOR‐dependent glycolysis in bladder cancer, promoting lactate accumulation, increased lactylation, H3K27la enrichment at the HK2 promoter, and HK2 transcription. HK2 reinforces glycolysis, sustaining a metabolic–epigenetic program associated with tumor progression, recurrence, and metastasis.
