Sugary Signal: Fructose From Senescent Cancer Cells May Drive Ovarian Tumor Spread

A Nature Aging study shows fructose secreted by chemotherapy‑induced senescent ovarian cancer cells acts as a signaling molecule that reduces cell adhesion and promotes detachment and metastasis in cell cultures and mice; altering fructose metabolism blocked movement, and high-fructose intake worsened spread in animals, suggesting dietary fructose restriction and senolytic therapies could improve treatment outcomes—though findings are preclinical and not yet applicable to humans.
