MSI-1436

Mice
Male AKR/J mice are randomLy placed on ad libitum 10, 45, or 60% fat kcal diets. After -14 weeks, mice are randomly assigned to three treatment groups (n=5-8 mice/group); MSI-1436 (initial dose of 10 mg/kg with three subsequent weekly doses of 5 mg/kg, intraperitoneally), vehicle (saline, 10 mL/kg, weekly 4×), or pair-fed (PF). PF animals are injected with saline (weekly 4×) and allotted the amount of food consumed daily by MSI-1436-treated animals. On day 23, mice are anesthetized and euthanized for blood and tissue collection, respectively. Plasma is obtained following centrifugation of blood 14,000 rpm for 10 min at 4°C.
Rats
Nine-week-old male Sprague-Dawley rats (225-260 g) with ad libitum access to normal rodent chow are dosed intraperitoneally with MSI-1436 (10 mg/kg, IP) or saline. After an overnight fast, the rats are dosed intraperitoneally with saline or 100 U/kg of insulin. At 30 min after dose, animals are killed, and hypothalami are harvested and homogenized in 1 mL of tissue extraction reagent plus phosphatase and protease inhibitors. Samples are centrifuged (14,000 rpm for 10 min at 4°C), and the protein content of the supernatants are quantitated via BCA kit.
