Project description: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 manufacturers instructions and stored at -80 o C.<br>

Project description:We fed mice fot 6 weeks with either a high-fat diet or standard chow with sucrose supplemented drinking water We used microarrays to detail the global changes of gene expression induced by the two dietary regimes in liver, adipose and muscle tissues.

Project description:Exposure to high levels of arsenic in drinking water is associated with several types of cancers including lung, bladder and skin, as well as vascular disease and diabetes. Drinking water standards are based primarily on epidemiology and extrapolation from higher dose experiments, rather than measurements of phenotypic changes associated with chronic exposure to levels of arsenic similar to the current standard of 10ppb, and little is known about the difference between arsenic in food as opposed to arsenic in water. Measurement of phenotypic changes at low doses may be confounded by the effect of laboratory diet, in part because of trace amounts of arsenic in standard laboratory chows, but also because of broad metabolic changes in response to the chow itself. Finally, this series contrasts 8hr, 1mg/kg injected arsenic with the various chronic exposures, and also contrasts the acute effects of arsenic, dexamethasone or their combination. Male C57BL/6 mice were fed on two commercially available laboratory diets (LRD-5001 and AIN-76A) were chronically exposed, through drinking water or food, to environmentally relevant concentrations of sodium arsenite, or acutely exposed to dexamethasone. Experiment Overall Design: Male C57BL/6 mice, fed on two commercially available laboratory diets (LRD-5001 and AIN-76A), were chronically exposed through drinking water or food, to environmentally relevant concentrations of sodium arsenite. Another group animals, fed on the AIN 76A diet, was IP injected with dexamethasone (1 mg/kg), sodium arsenite (1mg/kg), both dexamethosone and arsenite, or saline alone.

Project description:We used microarrays to detail the global programme of gene expression in the fetal lung late in gestation, from mothers that had been fed normal chow, high fibre, or acetate in the drinking water. The experiment was designed to examine the hypothesis that metabolites of the mother i.e. acetate could cross the placenta and influence gene transcription in the fetus. Diets used were "Normal chow" (NC) (8720310), or "High-fiber" (SF11-025) (Specialty feeds, Perth, Australia. Acetate (200 mM) was provided in the drinking water and refreshed three times per week. Gene expression in the lung may be affected by metabolites in utero. We examined whole lung of E21 fetuses from high-fiber fed mothers, normal chow fed mothers and acetate in drinking water fed mothers. Added fibre in the diet, or acetate in drinking water, would allow simple comparison with normal chow fed mothers, to determine whether fibre/acetate affected gene transcription in the fetal lung.

Project description:Supporting microarray data for manuscript entitled "OSTEOPONTIN AND PAI-1 EXPRESSION IN MALIGNANT HYPERTENSION: SUPPRESSION BY p38 MAPK INHIBITORS" submitted to the HYPERTENSION journal. Experiment Overall Design: Male spontaneously hypertensive stroke-prone rats (SHR-SP) were obtained from Charles River (Raleigh, NC). At 11 weeks of age, the SHR-SP were randomized into 2 groups, and fed either powdered chow diet (Purina 5001) with water ad lib; or a high-salt/high-fat diet consisting of 1% NaCl in the drinking water and 24.5% fat in the chow (from Harlan TekLad, Madison, Wisconsin). 6 replicate animals per diet per time point.
