⁢ ⁣A groundbreaking study from The University of Texas ⁢MD Anderson Cancer Center reveals a direct⁢ link between the glucose-fructose mix in sugary drinks and accelerated ⁢metastasis in ⁣advanced colorectal⁣ cancer. Published today in Nature Metabolism, the research identifies a specific enzyme activated by this sugar combination that drives cancer cell spread.

Key Findings:‍ The Sugar Mix makes a difference

⁤ Researchers,lead by ⁢Jihye Yun,Ph.D., assistant professor of Genetics, investigated the impact of sugary drinks on late-stage⁢ colorectal cancer.⁣ Their experiments compared the effects of a glucose-fructose mix – ⁢the typical composition of many sweetened beverages – to glucose and fructose administered separately.Crucially,only the glucose-fructose combination substantially ⁣increased cancer cell⁢ mobility,leading to faster‍ spread to the liver,the⁤ most frequent site of⁣ colorectal cancer metastasis.

This isn’t⁤ simply ⁤about sugar intake;⁤ the combination of glucose and fructose appears to be the critical factor. The study demonstrates that the sugar mix activates an enzyme called ⁣sorbitol dehydrogenase (SORD). SORD, in turn, boosts glucose metabolism and triggers the cholesterol pathway, ultimately fueling the metastatic process.

SORD: A New Target for Anti-Metastasis Therapies?

⁢ The cholesterol⁣ pathway activated by SORD ⁤is the same one targeted by statins,⁣ commonly prescribed medications for managing high cholesterol. Interestingly,‍ the researchers found that blocking SORD significantly ⁢slowed metastasis, even ‍when the sugar mix was present. This suggests ⁢that inhibiting SORD could represent a novel‍ therapeutic strategy ⁣to combat cancer‍ spread.

“Our findings highlight that daily diet⁢ matters not⁣ only for cancer risk but⁤ also for how the disease progresses once it has developed,” explains Dr. Yun. “This is a critical distinction. We frequently enough focus on prevention, but this research shows that dietary choices can influence the course of the disease even after a diagnosis.”

Understanding⁣ the Mechanism: How Glucose-Fructose Activates SORD

The researchers delved into the biochemical mechanisms underlying the observed effects. The glucose-fructose mix leads to increased ⁤levels of sorbitol, an intermediate metabolite. This sorbitol accumulation activates SORD, which ‍then promotes the synthesis of cholesterol. Elevated cholesterol levels are known to enhance cancer cell migration and invasion, contributing to metastasis.
