phenotype observed in females
phenotype observed in males
N normal phenotype
adipose tissue
• in mice fed a high-fat diet at room temperature
• defective beige fat thermogenesis
• reduced [18F] fluorodeoxyglucose uptake in mice fed a high-fat diet indicating reduced thermogenic brown adipose tissue
• mice treated with NE fail to exhibit an increase in oxygen consumption in brown adipose tissue unlike in wild-type tissues
• however, uptake in white adipose tissue is normal

homeostasis/metabolism
N
• mice exhibit normal energy expenditure or energy intake when housed at 22 Celsius
• blunted temperature response to norepinephrine treatment
• after cold-exposure, mice exhibit difficulty maintaining core body temperature compared with wild-type mice
• lower baseline energy expenditure in mice fed a high-fat diet at room temperature
• mice fed a high-fat diet at room temperature exhibit accelerated weight gain compared with similarly treated wild-type mice
• mice treated with NE fail to exhibit an increase in oxygen consumption in brown adipose tissue unlike in wild-type tissues
• in mice fed a high-fat diet at room temperature
• in mice fed a high-fat diet at room temperature

growth/size/body
• in mice fed a high-fat diet at room temperature
• mice fed a high-fat diet at room temperature exhibit accelerated weight gain compared with similarly treated wild-type mice
• in mice fed a high-fat diet

liver/biliary system
• in mice fed a high-fat diet
• in mice fed a high-fat diet
