Effect of insulin on AQP9 levels in liver. (A) Insulin injection. (Top) Anti-AQP9 immunoblot of liver membranes from three rats killed 24 h after injection of buffer or 5 units/kg regular insulin, as indicated. (Middle) Scanning densities of anti-AQP9 immunoblot. (Bottom) Average blood levels of glucose at death. (B) Streptozotocin pretreatment followed by insulin injection. (Top) Anti-AQP9 immunoblot of liver membranes from three rats killed 9 days after injection of buffer (control), 100 mg/kg streptozotocin (STZ), or streptozotocin followed by 4 days of bidaily injections of 13 units/kg NPH insulin (STZ + ins). (Middle) Scanning densities of anti-AQP9 immunoblot. (Bottom) Average blood levels of glucose at death. Values represent mean ± SD from three rats.
