When scientists genetically engineered mice so that they could not generate an amino acid called cysteine, and then fed the mice a diet without any cysteine in it, the mice lost 30% of their body ...

In a new study of mice, researchers have found that an experimental drug that breaks down the amino acid cysteine slows pancreatic tumor growth by causing ferroptosis, an unusual form of cell death. A ...

Consuming fewer calories is largely accepted as a way to improve health and lose weight, but a recently published study in Nature Metabolism points to a specific sulfur-containing amino acid cysteine ...
