- Pancreatic tumor cells use fructose to divide and proliferate, U.S. researchers said on Monday in a study that challenges the common wisdom that all sugars are the same.
Tumor cells fed both glucose and fructose used the two sugars in two different ways, the team at the University of California Los Angeles found.
They said their finding, published in the journal Cancer Research, may help explain other studies that have linked fructose intake with pancreatic cancer, one of the deadliest cancer types.
"These findings show that cancer cells can readily metabolize fructose to increase proliferation," Dr. Anthony Heaney of UCLA's Jonsson Cancer Center and colleagues wrote.
Heaney said his team found otherwise. They grew pancreatic cancer cells in lab dishes and fed them both glucose and fructose.
Tumor cells thrive on sugar but they used the fructose to proliferate. "Importantly, fructose and glucose metabolism are quite different," Heaney's team wrote.
