Using an enzyme to lower L-serine levels for cancer treatment

Therapeutic enzyme depletion of L-serine for cancer treatment

NIH-funded research University of Texas at Austin · NIH-11060061

This study is looking at a new way to help treat certain types of breast cancer by using a special enzyme to lower levels of L-serine, a nutrient that tumors need to grow, making it easier for patients with luminal/ER+ breast tumors to fight their cancer without having to change their diets too much.

What this research studies

This research investigates the use of a therapeutic enzyme to deplete L-serine, an essential nutrient for tumor growth, as a novel approach to cancer treatment. The study focuses on luminal/ER+ breast tumors, which cannot produce serine on their own and are therefore particularly susceptible to serine deprivation. By employing an engineered human serine dehydratase (eSDH), the research aims to significantly reduce circulating serine levels in the body without requiring drastic dietary changes. This method could potentially inhibit tumor growth more effectively than current dietary approaches.

Who could benefit from this research

Good fit: Ideal candidates for this research are patients diagnosed with luminal/ER+ breast cancer or other cancers that are dependent on L-serine for growth.

Not a fit: Patients with cancers that do not rely on L-serine for growth or those who are not diagnosed with the specified types of cancer may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide a new, effective treatment option for patients with certain types of cancer, particularly those with luminal/ER+ breast tumors.

How similar studies have performed: Other research has shown promise in using enzyme therapies for cancer treatment, making this approach a potentially viable option.
