|
| Organism |

|
| Treatment protocol |
As described in the paper. Briefly, mice were fasted for 10 h and were given 2 g/kg BM of PO (Landkrone, Germany) or water (VCL) per gavage. Lateral tail vein blood samples were obtained prior to treatment and 2 hours after. 6 hours after treatment, mice were euthanized with isoflurane and a vena cava-blood sample was collected, centrifuged at 4 °C, and plasma aliquots were immediately frozen in liquid nitrogen. Liver was dissected and immediately snap frozen in liquid nitrogen. For mice undergoing an hyperinsulinemic-euglycemic clamp, a permanent jugular vein catheter was placed in male C57BL/6NTac mice, while under ketamine/xylazine-anesthesia. 6-7 days later, mice were fasted for 10 hours, then received 2g/ kg BM PO or VCL via gavage. 6 hours later, unrestrained, conscious mice underwent euglycemic hyperinsulinemic clamp.
After 110 minutes of primed-continuous [3-3H]glucose infusion (1.85 kBq/min), a blood sample was collected to determine plasma insulin, glucose and [3-3H] glucose concentrations for calculating basal EGP. A [3-3H]glucose infusion (3.7 kBq/min) containing insulin (15 pmol/kg·min-1; HumulinR, Lilly, USA) was started. Blood glucose concentrations were measured every 10 minutes and target glycemia established by adjusting the GIR. At minute 120, 2-deoxy-D-[1-14C]glucose (370 kBq) was injected IV, to assess rates of tissue specific glucose uptake (Rg). Mice were euthanized by means of an IV ketamine/ xylazine injection. Liver was collected, immediately snap-frozen in liquid nitrogen, and stored at -80°C.
