⁢ ⁣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.
