In summary, these evidences suggest that OXPHOS is required for … WebMay 31, 2024 · Abstract. Cancer cells have upregulated glycolysis compared with normal cells, which has led many to the assumption that oxidative phosphorylation (OXPHOS) is downregulated in all cancers. However, recent studies have shown that OXPHOS can be also upregulated in certain cancers, including leukemias, lymphomas, pancreatic ductal …

WebThis may imply that COPD AMs may have more available glucose intermediates to harness glycolysis in the absence of OXPHOS to generate the ATP required for efferocytosis. Consistently, oligomycin, an inhibitor of OXPHOS, suppressed efferocytosis in MDMs, whereas inhibiting glycolysis suppressed efferocytosis only when OXPHOS was blocked. WebUncoupling between glycolysis and oxphos involves the partitioning between pyruvate (the primary substrate for glucose-driven oxphos) and lactate. Lactate is generally thought to be a terminal metabolite for glycolysis that must be converted back to pyruvate in the cytosol to serve as a substrate for oxphos ( Nelson and Cox, 2024 ), though this ... the douglas house houghton
