Researchers have unveiled a novel method to sort out weight problems by focusing on fats absorption within the small gut. The cutting-edge nanoparticle system, engineered to ship therapeutic molecules on to the digestive tract, has proven important potential to stop diet-induced weight problems. The work is revealed within the journal Superior Science.
Offered at UEG Week 2024, the examine focuses on an enzyme known as Sterol O-acyltransferase 2 (SOAT2), which performs a crucial position in fats absorption within the small gut. By inhibiting this enzyme within the small gut, the examine affords a promising therapeutic method to cut back fats absorption and doubtlessly forestall weight problems.
Regardless of in depth analysis into fats metabolism, efficient inhibitors of intestinal fatty acid uptake have till now remained elusive. “For years, researchers have studied fat metabolism, but finding an effective way to block fat absorption has been difficult,” defined lead researcher Dr. Wentao Shao. “While most strategies focus on reducing dietary fat intake, our approach targets the body’s fat absorption process directly.”
The analysis group developed an revolutionary supply system utilizing nanoparticles—a tiny capsule comprised of a polymer core, coated in a protecting shell.
The system was designed to effectively carry small interfering RNAs (siRNAs) to the small gut, the place they’ll scale back SOAT2 expression, inhibiting fats absorption. In mouse fashions, the animals handled with the nanoparticle remedy absorbed much less fats and prevented weight problems, even on a high-fat weight loss plan.
“This oral treatment offers several advantages,” mentioned Dr. Shao. “It’s non-invasive, has low toxicity, and it has high potential for better patient compliance compared to current obesity treatments, which are often invasive or difficult to maintain. This makes it a promising alternative.”
The examine additionally uncovered the underlying mechanism by which SOAT2 regulates fats absorption. Inhibition of SOAT2 within the small gut triggers degradation of CD36, a protein chargeable for transporting fats. This course of includes each mobile stress and the recruitment of E3 ligase RNF5, an enzyme that enhances CD36 degradation.
Earlier research have proven that blocking hepatic SOAT2 results in fats accumulation within the liver, whereas this intestine-specific method circumvents that danger, providing a safer and extra centered therapy for weight problems.
Professor Zhaoyan Jiang, examine supervisor, defined, “One of the most exciting aspects of this therapy is its ability to target fat absorption in the intestines without affecting the liver. This is important because previous studies showed that blocking SOAT2 in the liver can lead to fat buildup there—a risk our treatment avoids by focusing only on intestinal SOAT2.”
Wanting forward, the analysis group plans to check the nanoparticle system in bigger animal fashions to verify its effectiveness and security for potential use in people.
“We believe that this nanoparticle system represents a breakthrough in obesity management, offering a new solution that tackles both fat metabolism and diet-related weight gain, potentially ushering in a new era of more effective treatments,” Professor Jiang concluded.
