Web31 mrt. 2024 · Glioblastoma (GBM) is an aggressive brain cancer with a median survival time of 14.6 months after diagnosis. GBM cells have altered metabolism and exhibit the Warburg effect, preferentially producing lactate under aerobic conditions. After standard-of-care treatment for GBM, there is an almost 100% recurrence rate. Hypoxia-adapted, …
WebCoupling glycolysis and mitochondrial tricarboxylic acid cycle, pyruvate dehydrogenase (PDH) complex (PDHC) is highly responsive to cellular demands through multiple mechanisms, including PDH phosphorylation. PDHC also produces acetyl-CoA for protein acetylation involved in circadian regulation of metabolism. Thiamine (vitamin B1) … Web2 apr. 2024 · The proteins LDHA, PDK1, PKM2, HEX I, HEX II and PFKFB2 – which are enzymes involved in the regulation of glycolysis – were upregulated during hypoxia. However, these proteins, except LDHA, showed no significant difference in expression in PMSCs overexpressing Lin28 (Figure 2A ).
Web10 apr. 2024 · Glycolysis generates only two ATP molecules per glucose molecule, whereas oxidative phosphorylation produces up to 36 ATPs per glucose molecule . In cancer cells, a large proportion of the available pyruvate is reduced into lactate and only a few pyruvate molecules enter the TCA cycle for oxidative phosphorylation [ 5 , 6 , 29 ]. Web18 mrt. 2024 · LDHA (LDH5, M-LDH or M4) is predominantly found in anaerobic tissues like the skeletal muscle and the liver. LDHA needs a higher pyruvate concentration for the maximum enzyme activity. It means...
