Scientists at the Rudolf Virchow Centre discovered that vitamin B2 may help cancer cells stay alive. They found that vitamin B2 metabolism can shield cancer cells from destruction.

Vitamin B2 is an essential nutrient for human health, but new research suggests it may also help cancer cells survive. The study was published in Nature Cell Biology and involved scientists at the Rudolf Virchow Centre (RVZ) at Julius-Maximilians-Universität Würzburg (JMU). Vitamin B2, also known as riboflavin, cannot be produced by the body and must come from food sources such as dairy products, eggs, meat, and green vegetables. Once absorbed, vitamin B2 is converted into molecules that help protect cells from oxidative damage and support other important biological functions.

The researchers found that vitamin B2 metabolism plays a crucial role in protecting cancer cells from ferroptosis, a special form of programmed cell death. Ferroptosis occurs when iron-driven damage to cell membranes overwhelms a cell's antioxidant defenses. Cancer cells often avoid this fate by strengthening systems that protect them from oxidative stress.

The study suggests that blocking riboflavin-related pathways could make tumors more vulnerable to ferroptosis and easier to destroy. The researchers tested roseoflavin, a naturally occurring compound produced by bacteria that has a structure similar to vitamin B2. They found that roseoflavin was able to trigger ferroptosis even at low concentrations.

The findings suggest that targeting vitamin B2 metabolism could become a promising new approach for future cancer therapies based on ferroptosis.

Why It Matters

Understanding how vitamin B2 metabolism influences ferroptosis could eventually help scientists better understand a wide range of diseases involving excessive or insufficient cell death, including neurodegenerative diseases and tissue damage following organ transplantation or ischemia-reperfusion injury.
