Wistar Study: Chemotherapy-Induced Senescent Cells Produce Fructose That Drives Ovarian Cancer Spread

03 Aug Wistar Study: Chemotherapy-Induced Senescent Cells Produce Fructose That Drives Ovarian Cancer Spread

Aidan Cole, PhD

MedicalResearch.com: What is the background for this study? What are the main findings?

Dr. Cole: Our lab was interested in what happens in a tumor after chemotherapy treatment when some cells stop proliferating and growing the tumor but are not killed. These are called senescent cells, and they are of particular interest in ovarian cancer because of the prevalence of cancer recurrence and spread after initially responding to treatment.

The biggest finding is we learned how these senescent cells communicate with cancerous cells to get them to loosen their grip on the tumor and spread to other parts of the body. This communication occurs when senescent cells produce a sugar called fructose. For the first time, we’ve shown that a nutrient can be produced in these senescent cells and used by cancer cells in a way that worsens cancer spread. This builds on research previously covered on MedicalResearch.com exploring how senescence in ovarian cancer cells may contribute to chemotherapy resistance.

MedicalResearch.com: What might be the potential clinical implications?

Dr. Cole: I think there could be many clinical implications! Our study highlights fructose as the signal that leads to decreased cholesterol in cancer cells. There are FDA approved drugs that target fructose signaling developed for diabetes and drugs designed to lower cholesterol. Our research raises questions about how those medications should or should not be combined with chemotherapy. Also, fructose is a huge part of the American diet through the prevalence of high fructose corn syrup. It would be very interesting to see if in patients, decreasing fructose consumption is something patients could do to positively impact their prognosis.

MedicalResearch.com: What recommendations do you have for future research as a result of this study?

Dr. Cole: The research is still early, but it’s pretty clear we need to find ways to target the effects of senescent cells after chemotherapy. Now we know about fructose and past research has identified inflammation coming from these cells, but what other ways are senescent cells communicating? Additionally, if these signals can be nutrients like fructose, how does what patients eat and drink influence their cancer progression?

MedicalResearch.com: Is there anything else you would like to add? Any disclosures?

Dr. Cole: One takeaway is that we still don’t know exactly what happens in a tumor after chemotherapy treatment. This is one way a tumor can change after treatment and may give us a lead on how to make treatments more effective. Another is that nutrients like fructose can be used by cancer cells both as food and as signals to change their behavior. How other nutrients, including dietary nutrients, are used and how they change cancer progression is still an open area of research.

Disclosures: None disclosed.
