• on a standard chow diet, 9 week-old mice given an injection of diphtheria toxin, with a second injection 1 week later, to ablate oxytocin-expressing neurons (lesioned mice), showed comparable body weight through 20 weeks of age
|
• when 9 week-old mice were given an injection of diphtheria toxin, with a second injection 1 week later, and maintained on a high fat diet following treatment, males displayed comparable body weight to controls up to 14 weeks of age, then develop higher body weight relative to controls at 22 weeks of age; in contrast, females show no difference in body weight compared to controls up to 22 weeks of age
|
• diphtheria toxin-treated males (lesioned) show significantly higher fat mass; lean masses are comparable
|
N |
• average daily food consumption measured over one week in control and lesioned (diphtheria toxin-treated) males are similar on normal chow and high fat diets
• treatment of control and lesioned mice with MTII (melanocortin receptor agonist) reduced feeding in the dark to similar degrees in both cohorts
|
• when 9 week-old mice were given an injection of diphtheria toxin, with a second injection 1 week later, and maintained on a high fat diet following treatment, males displayed comparable body weight to controls up to 14 weeks of age, then develop higher body weight relative to controls at 22 weeks of age; in contrast, females show no difference in body weight compared to controls up to 22 weeks of age
|
• lesioned mice on a high fat diet show lower oxygen consumption during a 2 day period of high fat diet, particularly during the dark cycle, compared to controls; during a 2 day period on normal chow diet, oxygen consumption is comparable between the two genotypes
|
• after overnight fasting, leptin administration caused a 25% reduction in 2-hour feeding in lesioned mice and had no significant effect on 4- and 24-hour feeding whereas control mice treated with leptin showed a 25% decrease in 2- and 4-hour feeding and blunted 24-hour feeding by 20%
