Promising new approach to treating type 2 diabetes

An estimated 462 million people around the world suffer from Type 2 diabetes, a chronic disease in which the body has problems using sugar as a fuel, leading to a buildup of sugar in the blood and chronic health issues.

Rising IBD incidence highlights need for non-invasive biomarkers in diagnosis

The global burden of inflammatory bowel diseases (IBD), primarily Crohn's disease (CD) and ulcerative colitis (UC), continues to rise. Recent data show incidence rates of up to 17.8 cases per 100,000 person-years for CD and even higher for UC, reaching 28.4 per 100,000 person-years. These diseases primarily affect older populations and vary geographically, with higher prevalence rates in highly developed countries.

SCARB2 deficiency disrupts bile acid metabolism and gut microbiome

The study details the connection between SCARB2 deficiency and gastrointestinal dysfunction, revealing that the loss of SCARB2 leads to alterations in bile acid metabolism and dysbiosis in the gut microbiome. This disruption affects the signaling pathway involving FXR, which normally regulates bile acid synthesis and intestinal lipid absorption. The hyperactive FXR in Scarb2-deficient mice leads to a decrease in epithelial cell turnover and lipid malabsorption, particularly impacting the absorption of vitamin E, which is crucial for maintaining neurological health. The researchers further explored the impact of these changes on the gut-liver axis and found alterations in the expression of genes related to bile acid synthesis.
