The Claim
In HT29 human colon cancer cells, acute glucose deprivation at 1.1 mM reduces cellular NADH levels, increases NAD+ levels, decreases the NADH/NAD+ ratio, reduces lactate production, and diminishes lactate dehydrogenase activity, indicating impaired aerobic glycolysis under low-glucose conditions.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When HT29 human colon cancer cells are deprived of glucose at 1.1 mM, their NADH levels drop, NAD+ levels rise, the NADH/NAD+ ratio falls, lactate production decreases, and lactate dehydrogenase activity is reduced, indicating a suppression of aerobic glycolysis.
See the scientific wording
In HT29 human colon cancer cells, acute glucose deprivation (1.1 mM) reduces cellular NADH levels and increases NAD+ levels, leading to a decreased NADH/NAD+ ratio, which is associated with reduced lactate production and diminished lactate dehydrogenase activity, indicating impaired aerobic glycolysis under low-glucose conditions.
When sugar levels drop, cells can't make enough pyruvate from glucose, so they can't convert pyruvate into lactate. This stops the recycling of NAD+ from NADH, causing NADH to drop and NAD+ to rise. Without enough NAD+, the enzyme that makes lactate can't work, so lactate production falls and the cell's sugar-burning process slows down.
What the research says
1 studyWhen colon cancer cells don't get enough sugar, they can't make energy the usual way, so they produce less of a chemical called lactate and have less NADH, which means their sugar-burning process slows down.
