Phosphorylation3
- Dr. Otto Warburg first described, more than 80 years ago, that a fundamental biochemical difference between tumor cells and their normal counterparts was that tumor cells rely on aerobic glycolysis for ATP generation, unlike most normal differentiated cells of the body, which use mitochondrial oxidative phosphorylation. (aacrjournals.org)
- Treg cells rely less on glycolysis, but rely on oxidative phosphorylation to produce energy. (medicaltrend.org)
- In the case of cancer-associated metabolic reprogramming, cancer cel s preferentially metabolize glu- cose through glycolysis rather than oxidative phosphorylation, even in the presence of oxygen [11-13]. (who.int)

Excess2
- In glucagonoma syndrome, glucagon levels are well in excess of 500 pg/mL and are reported to increase even further with the administration of intravenous tolbutamide. (medscape.com)
- It also has the ability to convert excess glucose into fatty acids for long-term energy storage. (proprofs.com)
Diabetes6
- Human investigations suggest that fenugreek can be beneficial as an adjunct in controlling high blood glucose and lipid levels in people with diabetes. (lww.com)
- At the molecular and structural level, mitochondrial biogenesis and mitochondrial function are altered in diabetes, as well as in insulin-resistant relatives of type 2 diabetic subjects ( 1 , 2 ). (diabetesjournals.org)
- Overall, our results illustrate that both exercise and antioxidant intervention improve blood glucose control in diabetes by promoting redox balance, despite different levels of redox state(s). (elifesciences.org)
- These results indicate that the AMPK signaling activation, combined with oxidative damage markers, could act as sentinel biomarkers, reflecting the threshold of redox balance that is linked to effective glucose control in diabetes. (elifesciences.org)

- In non-adipose tissues lacking perilipin-1 the role of HSL is less well characterized and the enzyme expression is low. (imingo.net)
Lactic acid7
- Although the immunological status of the two environments is quite different, their metabolic status is similar: both are hypoxic, with elevated levels of lactic acid and other metabolic by-products, and low nutrient content. (medicaltrend.org)
- describing that compared with normal tissues, lactic acid is in tumor and inflammation. (medicaltrend.org)
- In IMIDs, lactic acid is produced by mesenchymal fibroblasts and metabolically active infiltrating immune cells, and is a key driver of the microenvironment of inflammatory tissues. (medicaltrend.org)
