phenotype observed in females
phenotype observed in males
N normal phenotype
• by 67 weeks of age the mortality rate is about 15% in both males and females compared to 0% in heterozygous and non-transgenic mice

• significant increase in body weight by 6 to 7 weeks of age
• females and males are 119 and 37% heavier than age-matched non-transgenic controls by 69 weeks of age
• at 24 weeks of age, mean lengths of female and male mice are increased by about 11 and 7%, respectively

adipose tissue
• increase in both total amount and percent of body fat
• increase in both total amount and percent of body fat

• increased about 10-fold compared to non-transgenic controls
• increased by 95% compared to non-transgenic controls
• elevation in the LDL but not HDL, serum cholesterol levels
• develops by 9 weeks of age
• in mice older than 8 weeks
• detected at 6 weeks of age prior to onset of obesity and in mice over 8 weeks of age

• mice consume 57% more food than non-transgenic controls
• however, no change in energy expenditure is detected
• in a resident-intruder assay latencies to first biting attacks are shorter and duration of biting attacks are longer compared to non-transgenic controls
