Transcription profiling of liver and white adipose tissue from mice fed standard or test diets with or without monosodium glutamate in their water

ABSTRACT: C57BL/6J mice were from The Jackson Laboratory (Maine, USA) and were housed/caged and fed a standard chow diet until 6 weeks of age whereupon they were placed in one of 4 different dietary regimens for a period of 3 weeks prior to mating. Mice were housed under pathogen-free conditions of 21± 1°C, 40 to 60% humidity, and a 12 h-12 h light/dark cycle. The 4 diet regimens used in this study were: [1] ad lib Standard Chow (Control diet) with ad lib drinking water. [2] Ad lib Standard Chow, with ad lib drinking water containing 0.64 mg/ml (97 mg/Kg body weight) monosodium glutamate (MSG diet). [3] Ad lib Test Diet Purina 5001 with 20% 55-HFCS (5B4K, Purina, USA), and ad lib drinking water (HFCS diet). [4] Ad lib Purina 5001 with 20% 55-HFCS, and ad lib drinking water containing 0.64 mg/ml (97 mg/K body weight) monosodium glutamate (HFCS+MSG diet). See Table 1 for diet composition. Following mating, the 4 groups of dams were maintained on their respective diets throughout the gestation and nursing period. Male offspring used in these experiments were weighed, then weaned onto the same diets and maintained in this regimen until they reached either 16 or 32 weeks of age. Total RNA was prepared from the liver and visceral white adipose tissue (WAT) taken from 16-week-old mice in the 4 different diet groups using Qiagen RNeasy Kit (Qiagen USA) according to the manufacturer’s instructions and stored at -80 o C.
