A single amino acid may sit at an unexpected chokepoint in the body’s defense against both cancer and viral infection. Researchers at Rockefeller University report that when levels of arginine fall, ...

A new review in Medical Oncology examines marine microbial arginase as a stable enzyme platform for arginine deprivation ...

A study published July 30, 2026, in the journal Cell by researchers at Rockefeller University reveals a precise molecular mechanism by which a single dietary amino acid — arginine — controls whether ...

The amino acid arginine helps to keep the human body humming, most notably by synthesizing proteins that carry out a range of cellular processes. It’s produced by our bodies and found in common ...

A recent publication in Cell demonstrates that arginine, an amino acid that facilitates various cellular processes, including cellular growth, also promotes tumor growth. The study shows that arginine ...

Chinese scientists have revealed a hidden metabolic partnership between breast cancer cells and immune cells that drives aggressive tumor behavior and resistance to immunotherapies. The study sheds ...

Scientists at Rockefeller University found that low levels of arginine may help cancer cells and viruses evade immune detection by reducing production of MHC-I, a crucial cellular "warning system" ...

Arginine plays a dual role in cancer biology as both a signalling metabolite that activates key pathways, notably mTOR, and as a precursor for nitric oxide, polyamines and other biosynthetic processes ...

Epithelial ovarian cancer (EOC) is the leading cause of death among gynecological malignancies, and the tumors with advanced-stage are frequently characterized by extensive metastasis. Although ...

Treatment with arginine, one of the amino-acid building blocks of proteins, enhanced the effectiveness of radiation therapy in cancer patients with brain metastases, in a proof-of-concept, randomized ...
