How cancer cells fuel their growth
Scientists surprised to find that amino acids, not sugar, supply most building blocks for tumor cells.
Although cells consume glucose and the amino acid glutamine at very high rates, the researchers found that those two molecules contribute little to the mass of new cells — glucose accounts for 10 to 15 percent of the carbon found in the cells, while glutamine contributes about 10 percent of the carbon. Instead, the largest contributors to cell mass were amino acids, which make up proteins. As a group, amino acids (excluding glutamine) contribute the majority of the carbon atoms found in new cells and 20 to 40 percent of the total mass.
I can’t recall any of my #FuckCancer reading pointing to amino acids at all.
Most of it has focused on mutations, possible points of inhibition, and connections to glucose and glutamine.
Now I’m totally confused.
