A new study from Van Andel Institute reveals that controlling cancer cells’ access to fat molecules could significantly improve the effectiveness of certain cancer treatments. The research, published in Cell Chemical Biology on October 22, 2024, suggests that dietary strategies could potentially be tailored to enhance cancer therapy outcomes.
Summary: Scientists at Van Andel Institute discovered that limiting cancer cells’ access to fats could enhance the effectiveness of treatments targeting ferroptosis, a specific type of cell death. This finding opens new possibilities for developing specialized diets to support cancer therapies.

“We want to make cancer treatment more effective,” said Evan Lien, Ph.D., an assistant professor at VAI and the study’s corresponding author. “The best way to do this is by understanding how cancer cells behave and identifying ways to break through their defenses. Our findings are an important step toward evidence-based diets that could one day augment existing therapies.”
Understanding Ferroptosis and Cancer Cell Death
The research focuses on ferroptosis, a specialized form of cell death that occurs when fat molecules within cancer cells become damaged. This process has gained attention in recent years as a promising avenue for developing new cancer-fighting strategies.
Cancer cells typically manipulate normal cellular processes to their advantage, stealing vital resources like fats to fuel their growth and spread. However, the study demonstrated that when researchers cut off cancer cells’ access to fats, the cells became highly vulnerable to ferroptosis and drugs designed to trigger this type of cell death.
Future Implications and Dietary Applications
The implications of this research could extend beyond the laboratory. “Diet is something that’s relatively easy to modify,” Lien said. “We’re not there yet, but the thing we’re most excited about is how we might be able to use what we learn to one day design diets tailored to different types of treatment. That could be transformative.”
While the initial findings are promising, the research team emphasizes that additional studies are needed to replicate these results in other cancer models. They are currently investigating how different types and amounts of fats might be manipulated through diet to enhance the effectiveness of ferroptosis-inducing treatments.
