A Common Vitamin Helps Cancer Defend Itself – But Could Also Let Us Fight It

University of Würzburg researchers found that vitamin B2 helps cancer cells resist ferroptosis by supporting the FSP1-RFK pathway.

In lab tests, the vitamin B2 mimic roseoflavin disrupted this defense and made cancer cells more vulnerable to ferroptosis.

The findings point to a nutrient-linked survival mechanism in tumors and a possible new angle for cancer treatment by blocking it.
