Researchers at the University of Cologne have demonstrated that, while various cellular states of small cell lung cancer are ...

A single-cell and spatial atlas of 66 breast tumors shows cysteine cathepsins occupy specific immune, epithelial and stromal ...

In an important step during the early evolution of life on Earth, the formation of the amino acid cysteine delivered vital catalysts, which enabled the earliest protein molecules to form in water, ...

Eating a high-fat diet will typically result in weight gain. But a new study published in Nature Metabolism has uncovered an unexpected biological loophole that turns fat storage into fat usage. In ...

A synthetic eight-residue peptide modeled on the cobalt nitrile hydratase metal-binding motif binds Co(II) in two distinct ...

A diet rich in the amino acid cysteine may have rejuvenating effects in the small intestine, according to a new study from MIT. This amino acid, the researchers discovered, can turn on an immune ...

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 ...
