behavior/neurological
|
• after initial i.p. injection of 3.5 mg/kg ethanol, mutants show longer latencies in regaining righting reflex compared to controls
|
|
• mice show a longer latency to resume locomotion after first i.p. injection of ethanol compared to wild-type
|
|
• prior to alcohol treatment on first and fifth days of testing , mutant withdraw from hot plate at similar pace to controls; 4 hours after injection, mutants move away from hot plate more slowly than controls on both the first and fifth test day

|
behavior/neurological
|
• hyperphagia that normally occurs from ghrelin treatment is severely attenuated in these mice
• food intake was about half that of controls both 1 and 2 hours after ghrelin treatment
• this attenuation in ghrelin-induced food intake still occurred if ghrelin was administered directly into the hypothalamus
|
nervous system
|
• hypothalamus cells fail to increase their number of mitochondria in response to ghrelin treatment where as in wild-type mitochondrial numbers are significantly increased
|
|
• uncoupled oxygen consumption by hypothalamic mitochondria is increased in wild-type mice treated with ghrelin hormone but not in these mutant mice
• total respiratory capacity of these mitochondria also fail to increase in mice treated with ghrelin hormone compared to wild-type which have about a 50% increase in total respiratory capacity
• the membrane potential of mitochondria fail to be lowered by ghrelin treatment as in controls
• hypothalamic mitochondria significantly increase their production of reactive oxygen species in response to ghrelin-treatment unlike in wild-type mice where increases in ROS production are limited

nervous system
|
• ghrelin induced recruitment of miniature inhibitory postsynaptic currents
on GFP-labeled cells within the hypothalamus was significantly elevated in wild-type animals but not in these mice
|
|
• grehlin increases the number of symmetric (inhibitory) synapses and decreases the number of asymmetric (excitatory) synapases found in hypothalamus in wild-type but not mutant mice
