phenotype observed in males
N normal phenotype
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

N normal phenotype
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
