What this research studies

If you have kidney cancer, UCLA researchers are studying whether tumors need the amino acid asparagine to keep growing. They lower asparagine around tumors using enzymes (L-asparaginase), by reducing dietary asparagine, and by using metformin to block the tumor’s ability to make asparagine. Most experiments so far use tumor cells and mice to measure tumor growth and molecular responses. If findings are promising, the team may move toward treatments or early human testing that target tumor metabolism.

Who could benefit from this research

Good fit: People with renal cell carcinoma (kidney cancer), particularly those whose tumors rely on altered amino acid metabolism, would be the most relevant candidates for related trials.

Not a fit: Patients whose tumors do not depend on asparagine or who cannot tolerate therapies like L-asparaginase or metformin may not benefit.

Why it matters

Potential benefit: If successful, this could slow kidney tumor growth and lead to new metabolic treatment options that add to existing therapies.

How similar studies have performed: Preclinical mouse and cell studies in lung, breast, and pancreatic cancers have shown that lowering asparagine can block tumor growth, and L-asparaginase is already used in some leukemias, but applying these approaches to kidney cancer is relatively new.
