The Claim
Supplementation with malate and glutamate (5 mM each) restores lactate levels in HT29 colon cancer cells under low glucose conditions (1.1 mM), while supplementation with succinate (5 mM) does not restore lactate levels, indicating that malate catabolism supports aerobic glycolysis under glucose limitation.
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.
In HT29 colon cancer cells grown with low glucose, adding malate and glutamate restores lactate production, but adding succinate does not, showing that malate breakdown sustains lactate generation when glucose is scarce.
See the scientific wording
Supplementation with malate and glutamate (M/G, 5 mM each) restores lactate levels in HT29 colon cancer cells under low glucose conditions (1.1 mM), whereas succinate (5 mM) does not, suggesting malate catabolism supports aerobic glycolysis when glucose is limited.
When sugar is scarce, cells stop making lactate because they run out of pyruvate. Malate and glutamate enter the cell and are converted into pyruvate inside the cytoplasm, which then allows lactate to be made again. This process keeps the cell's energy balance stable. Succinate cannot do this because it goes into a different part of the cell and does not produce pyruvate.
What the research says
1 studyWhen colon cancer cells don’t get enough sugar, they can’t make lactate — but adding malate and glutamate helps them make lactate again, like a backup fuel. Succinate doesn’t help at all.
