growth/size/body
N |
• rescue of the increased weight gain, of the fat stores, of hyperphagia and of the increased linear length seen in single Mc4r homozygotes
|
homeostasis/metabolism
respiratory system
N |
• rescue of the depressed respiratory exchange ratio seen in single Mc4r homozygotes
|
growth/size/body
N |
• animals do not show significant changes in body weight up to 11 weeks of age
|
behavior/neurological
N |
• food intake shows no significant difference compared to controls
|
nervous system
N |
• deletion of Lepr in Slc17a6 neurons does not alter IPSC amplitude in Agrp neurons; IPSC frequency is decreased (not significantly) in Agrp
• excitatory postsynaptic currents (sEPSCs and mEPSCs) in Pomc1 neurons are not affected by Lepr deletion in Slc17a6 (glutamatergic) neurons
|
homeostasis/metabolism
adipose tissue
N |
• no increase in fat mass is observed at 10 weeks
