Researchers at The Wistar Institute discovered that chemotherapy-induced senescent ovarian cancer cells release fructose, which signals nearby cancer cells to detach and spread. The fructose reduces cholesterol in cell membranes, weakening the adhesion that keeps tumor cells together. The finding, published in Nature Aging, could point toward new strategies to prevent cancer recurrence, which accounts for 90% of cancer deaths.

  • Chemotherapy-induced senescent ovarian cancer cells secrete fructose, which signals neighboring cancer cells to detach and metastasize.
  • Fructose reduces cholesterol in cancer cell membranes, weakening adhesion and enabling spread—an effect unrelated to fructose's role as fuel.
  • The finding targets cancer recurrence, which causes 90% of cancer deaths, and suggests new intervention strategies.
  • Research was published in Nature Aging and is being widely covered across mainstream and scientific media outlets.

“Cancer can be just like the killer in a horror movie – it may seem like he's been destroyed forever by the Good Guy, but then he pops back up again to terrorize.”

“Similarly, chemotherapy is designed to kill cancer cells, but some of them still survive treatment by entering a state known as cellular senescence.”
