For ITT, the mice were fasted for 8 h under nonanesthetized conditions. Insulin-R (I9278, Sigma-Aldrich, St. Louis, MO, USA) was intraperitoneally injected (0.75 U/kg body weight) and blood samples from the tail vein were collected at 15, 30, 60, 90, and 120 min after insulin injection. Glucose levels were evaluated with Accu-Chek Performa glucometer (Boehringer-Mannheim, Indianapolis, IN, USA).

Glucose and Insulin Tolerance Tests
For ITT, the mice were fasted for 8 h under nonanesthetized conditions. Insulin-R (I9278, Sigma-Aldrich, St. Louis, MO, USA) was intraperitoneally injected (0.75 U/kg body weight) and blood samples from the tail vein were collected at 15, 30, 60, 90, and 120 min after insulin injection. Glucose levels were evaluated with Accu-Chek Performa glucometer (Boehringer-Mannheim, Indianapolis, IN, USA).
Glucose and Insulin Metabolism Assays
Intraperitoneal Glucose tolerance test (IPGTT), intraperitoneal insulin releasing test (IPIRT) and Insulin tolerance test (ITT) IPGTT and IPIRT were performed in mice after they fasted overnight for 16 has described previously (Niu et al., 2008) . At 0, 15, 30, 60, and 120min after glucose (2g/kg body weight for IPGTT or 3g/kg body weight for IPIRT) injection. For IPGTT about 1 mL blood sample was taken from the angular vein for testing blood glucose concentration using an automatic glucometer ACCU-CHEKâ Performa (Roche). For IPIRT about 20 mL blood sample was taken from the angular vein for testing insulin concentrations during IPGTT. Insulin concentration was assayed by an ELISA kit (Millipore). GLP-1 and glucagon were detected using ELISA kit (Millipore and R&D) according to the manufacturer's protocol.
ITT was performed in mice after fasted for 4h. At 0,15, 30, 60, 90, and 120 min after Human regular insulin (Eli Lilly) (0.1 U/ml in saline; 0.75 U/kg body weight) injection, about 1 mL blood sample was taken from the angular vein for testing blood glucose concentration using an automatic glucometer ACCU-CHEKâ Performa (Roche).

Intraperitoneal Glucose and Insulin Tolerance Tests
For insulin tolerance tests (ITT), mice were fasted for 6 h before intraperitoneal injection of 1 mU human insulin/g body weight (Insuman Rapid, Sanofi). Blood glucose levels were measured from tail vein blood before and 15, 30, 45, and 60 min after insulin application (ACCU-CHEK Performa, Roche).

Glucose Reabsorption and TEER Measurement
Trans-epithelial electrical resistance (TEER) is a well-known quantitative technique for measuring the integrity of tight junction dynamics in endothelial and epithelial fault cell culture models. Prior to evaluating the transport properties of drugs and chemicals, TEER levels are used as a reliable indicator of cell barrier integrity. TEER measurements have the advantage of being able to be performed in real time without cell damage. To measure TEER, an insert containing cells cultured on a chip for 14 days was transferred to a 6-well plate and then filled with badges. As TEER values can be affected by external factors such as temperature, paper discharge form, and cell algebra, the measurement was conducted with maximum error [22 (link)].
Glucose and Insulin Tolerance Tests
For ITTs, all mice were starved for 12 h, injected with a bolus of insulin (0.3 unit/kg of body weight), and their blood glucose levels were monitored using a handheld glucometer (ACCU-CHEK Performa, Roche) at 15, 30, 60, and 120 min.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
