A Common Sugar May Help Cancer Cells Break Free and Spread
Researchers found cisplatin can make dormant ovarian cancer cells release fructose-rich signals that help nearby cells detach and spread, with NDUFA5 required for the effect.
- On July 30, 2026, a Wistar Institute study published in Nature Aging found that cisplatin chemotherapy forces ovarian cancer cells into dormancy, triggering them to release fructose that signals nearby cells to spread.
- Platinum-Based chemotherapy often fails to prevent recurrence because metastasis accounts for roughly 90% of ovarian cancer deaths. While initial treatment response is typically strong, the cancer frequently returns and spreads throughout the abdominal cavity.
- Researchers discovered senescent cells produce fructose as a chemical signal driving cancer spread. In mice, a high-fructose diet increased metastasis, suggesting nutrition may influence cancer progression in previously unrecognized ways.
- Statins, taken by 39 million Americans, weakened connections between cancer cells in the study, prompting researchers to investigate potential interference with chemotherapy. Senior author Katherine Aird, Ph.D., professor and co-leader of the Molecular and Cellular Oncogenesis Program in the Ellen and Ronald Caplan Cancer Center at The Wistar Institute, cautioned against stopping prescribed medications.
- Though these findings are preclinical and require human validation, Aird said future interventions could include repurposing diabetes drugs or limiting processed fructose intake. Additional research is necessary to confirm whether these biological mechanisms drive cancer progression in patients.

A Common Sugar May Loosen Cancer Cells and Help Them Spread
Chemotherapy may kill most ovarian cancer cells, but the few that survive can turn dangerously active. By releasing fructose, they may help nearby tumor cells break free and spread. Researchers at The Wistar Institute uncovered this unexpected chain reaction while studying treatment-induced cellular senescence, a state in which damaged cancer cells stop dividing but remain [...]
A common sugar may help cancer cells break free and spread
Chemotherapy-surviving ovarian cancer cells may release fructose to help neighboring tumor cells loosen, escape, and spread. The discovery suggests that sugary diets and cholesterol-lowering drugs could influence cancer progression, though the effects have not yet been confirmed in patients.
A new study from the Wistar Institute in the United States has uncovered an unexpected link between fructose, a common sugar in the diet, and the spread of an aggressive form of ovarian cancer.
Fructose May Help Ovarian Cancer Spread After Chemo, New Study Finds
New research links fructose to ovarian cancer spread after chemo in mice, pointing to a protein that could be a drug target. The post Fructose May Help Ovarian Cancer Spread After Chemo, New Study Finds appeared first on StudyFinds.
