Hypothesis

Does early-life rapamycin treatment have sex- and age-specific metabolic effects in UM-HET3 mice?

Conclusion

Early-life rapamycin treatment has long-term, sex- and age-specific effects on metabolic parameters in mice.

Supporting Evidence

  • Male mice treated with rapamycin had lower body weight compared to controls.
  • Rapamycin treatment significantly reduced fat pad weights in males.
  • Fasting glucose levels were significantly raised in treated males at 2 months.
  • By 6 months, fasting glucose levels were significantly reduced in treated mice compared to controls.
  • Glucose tolerance was significantly increased by rapamycin in both sexes at 2 and 6 months.

Takeaway

Giving young mice rapamycin changes how their bodies handle sugar and fat, and these changes are different for boys and girls.

Methodology

UM-HET3 mice were treated with rapamycin from 15 to 56 days of age, and various metabolic parameters were measured.

Participant Demographics

UM-HET3 mice, both male and female.
