INTRO: A new study from researchers at The University of Texas MD Anderson Cancer Center shows that the glucose-fructose mix found in sugary drinks directly fuels metastasis in preclinical models of advanced colorectal cancer. The study was published today in Nature Metabolism.
What are the key findings of this study? A research team led by Jihye Yun, Ph.D., assistant professor of Genetics, studied how sugary drinks may affect late-stage colorectal cancer. Using laboratory cancer models, they compared the effects of the glucose-fructose mix found in most sugary drinks with those of glucose or fructose alone. Only the sugar mix made cancer cells more mobile, leading to faster spread to the liver — the most common site of colorectal cancer metastasis.
The sugar mix activated an enzyme called sorbitol dehydrogenase (SORD), which boosts glucose metabolism and triggers the cholesterol pathway, ultimately driving metastasis. This is the same pathway targeted by statins, common heart drugs that inhibit cholesterol production. Blocking SORD slowed metastasis, even with the sugar mix present. These findings suggest that targeting SORD could also offer an opportunity to block metastasis.
“Our findings highlight that daily diet matters not only for cancer risk but also for how the disease progresses once it has developed,” Yun said. “While these findings need further investigation, they suggest that reducing sugary drinks, targeting SORD or repurposing statins may benefit patients with colorectal cancer.” (MORE - details, no ads)
