WebIncreased concentration of plasma phenylalanine (PHE) concentrations. In classic PKU, the PHE is usually >1200. PHE concentrations are between 900 and 1200 μmol/L in moderate PKU, ∼600–900 μmol/L in mild PKU, and 360–600 μmol/L in hyperphenylalaninemia due to BH4 deficiency or other causes. Tyrosine concentrations may be low. WebOct 21, 2024 · The reliance of tumor cells on aerobic glycolysis is one of the emerging hallmarks of cancer. Pyruvate kinase M2 (PKM2), an important enzyme of glycolytic pathway, is highly expressed in a number of cancer cells. Tumor cells heavily depend on PKM2 to fulfill their divergent energetic and biosynthetic requirements, suggesting it as …
