Core Tip
Core Tip: Bile acids play an important role in the amelioration of type 2 diabetes following duodenal-jejunal bypass (DJB), and are elevated significantly in the serum postoperatively. Bile acids in the peripheral circulation reflect the amount of bile acids in the gut. Therefore, a further investigation of luminal bile acids following DJB is of great significance. Here we performed DJB in a high-fat diet/streptozotocin-induced diabetic rat model and demonstrated that DJB achieved rapid and durable improvement in glucose tolerance and led to increased total luminal bile acid concentrations with preferentially increased proportion of farnesoid X receptor (FXR) - inhibitory bile acids within the common limb. Intestinal ceramide synthesis was repressed with decreased serum ceramides, and this phenomenon could be partially antagonized by luminal supplementation of FXR activating bile acid (chenodeoxycholic acid). There observations suggest a novel mechanism of bile acids in metabolic regulation after DJB.
