Witryna29 wrz 2014 · This is the second irreversible reaction of the glycolytic pathway and a major glycolysis checkpoint. 11 PFK1 is stimulated by ADP/AMP, whereas citrate, long-chain fatty acids, lactate and ATP act ... Witryna30 gru 2024 · Aerobic glycolysis is associated with proliferation in many biological contexts, yet what drives this phenotype has not been fully explained. Luengo et al. show that cells engage in aerobic glycolysis when the demand for NAD+ exceeds the demand for ATP, which leads to impaired NAD+ regeneration by mitochondrial respiration.

Witryna11 kwi 2024 · Hepatic IDH2-deficiency inhibited gluconeogenesis and glycogenesis, but promoted glycolysis and β-oxidation. (A-B) Intraperitoneal pyruvate injection for intraperitoneal pyruvate tolerance tests (IPPTT) was conducted with WT and IDH2 LKO mice after SD or HFD consumption, and AUC was respectively calculated. n = 5–7 … Witryna20 sty 2024 · The NAD + and NADH (NAD(H)) redox couple is essential for a variety of electron-exchange-dependent biochemical reactions, particularly redox reactions involving oxidoreductase-mediated hydride ...
WitrynaCryptococcus neoformans is a human fungal pathogen that adapts its metabolism to cope with limited oxygen availability, nutrient deprivation and host phagocytes. To gain insight into cryptococcal metabolism, we optimized a protocol for the Seahorse Analyzer, which measures extracellular acidification rate (ECAR) and oxygen consumption rate … Witryna13 sie 2024 · Thiamine, one of the water-soluble vitamins, is especially important in glucose metabolism. It acts as a cofactor for enzymes that break down glucose for energy production (Figure 6.3.1 ). Additionally, thiamine plays a role in the synthesis of ribose from glucose and is therefore required for RNA, DNA, and ATP synthesis.
