growth/size/body
N |
• at 20-22 weeks of age, mice fed a high-glucose diet (HGD) show no differences in body weight or body mass composition relative to age- and diet-matched wild-type controls
|
• at 20-22 weeks of age, chow-fed mice show reduced fat mass in the overnight fasted and fed states
|
• at 20-22 weeks of age, chow-fed mice show increased lean body mass in the overnight fasted and fed states
|
homeostasis/metabolism
N |
• at 20-22 weeks of age, chow-fed mice show normal energy expenditure (EE) over 3 days (EE includes overnight fasting and 6 h refeeding) and normal plasma insulin and adiponectin levels after overnight fasting and 1 h refeeding
• mice fed a high-glucose diet (HGD) show no changes in EE or plasma insulin levels
|
• at 30 weeks of age, HGD-fed mice show a significantly lower respiratory exchange ratio (RER = VCO2/VO2) during overnight fasting and in the 6 h-refed state, suggesting preferential oxidation of lipids during the dark phase and in the refed state
|
• HGD-fed mice show markedly impaired glucose tolerance
|
• HGD-fed mice show markedly reduced insulin sensitivity
|
• HGD-fed mice show significantly lower plasma adiponectin concentrations
|
• HGD-fed mice show significantly reduced PDE3B (phosphodiesterase 3B, cGMP-inhibited) protein levels in epididymal WAT (eWAT)
|
• HGD-fed mice show significantly reduced mRNA expression of lipid metabolism genes (Dgat1, Acsl1, Acot3, Acot4, Hmgcs1, Abcg1 and Ldlr) and of Pde3b (phosphodiesterase 3B, cGMP-inhibited) in eWAT in the 1 h-refed state
|
• on a standard chow diet, 20-week-old mice fasted overnight and then i.p. injected with 0.3 U/kg insulin show significantly higher plasma fatty acid (FA) levels than similarly treated wild-type controls at 15-, 30- and 60- min postinjection
• similarly, on a chow diet, 20-week-old mice fasted overnight and then i.g. gavaged with 2.5 g/kg glucose to stimulate insulin secretion show significantly higher plasma FA levels than similarly treated wild-type controls at 15-min, but not at 30-min or 60-min, post gavage
|
adipose tissue
• at 20-22 weeks of age, chow-fed mice show reduced fat mass in the overnight fasted and fed states
|
behavior/neurological
N |
• at 20-22 weeks of age, chow-fed mice show normal food intake, as measured over 3 days
