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 ...

All proteins are built from the same 20 amino acids. One of these, cysteine, was assumed not to have been present at the origin of life. In a new study, scientists have recreated how cysteine was ...

A new research perspective was published in Aging, titled "Trioxidized cysteine and aging: a molecular binomial that extends far beyond classical proteinopathic paradigms." Oxidative stress ...

Pennington Biomedical researchers have identified cysteine, a sulfur-containing amino acid, as a key factor in weight loss. The study, published in Nature Metabolism, reveals that calorie-restrictive ...

Mice genetically engineered to lack the ability to make the amino acid cysteine, and fed a cysteine-free diet, lost 30 percent of their body weight in just one week, a new study shows. Published ...

Scientists found that reducing cysteine can turn stored white fat into brown fat. Scientists in the United States have discovered a biological "switch" that could play a vital role in weight loss. The ...
