N normal phenotype
adipose tissue
• the weight of these fat pads is significantly reduced in these mice on both a chow and a high fat diet
• mice have 45% lower body fat compared to controls at 10 months of age on a normal chow diet
• mice fed a high fat diet have 54% lower body fat than controls
• brown adipose tissue (BAT) appears to be pale and slightly enlarged compared with wild-type BAT at 3 months of age
• white adipocytes from the gonadal region mice have small and multiple lipid droplets compared to the unilocular lipid droplet of wild-type mice
• these adipocytes have defined minuscule lipid droplets distinguishable from each other, and occupy the cytosol like in brown adipocytes
• the sizes of lipid droplets in adipocytes from brown adipose tissue are significantly larger than that of wild-type mice
• the volume of mitochondria that are present in white adipocytes is dramatically increased and are full of straight or slightly wavy cristae that transverse the width of the mitochondria
• mitochondria from these white adipocytes have 2-fold higher mitochondrial oxidation
• white fat pad sizes are significantly smaller compared to littermate controls
• gonadal fat pads are about two-thirds smaller
• total lipid content of white adipose tissue from these fat pads is reduced 6 fold compared to wild-type at 3 months of age
• these fat pads have a dark red color and abundant blood vessel circulation
• the weight of these fat pads is significantly reduced in these mice on both a chow and a high fat diet
• the weight of these fat pads is significantly reduced in these mice on both a chow and a high fat diet
• the weight of these fat pads is significantly reduced in these mice on a chow diet

behavior/neurological
• food intake is 10% higher for these mice

homeostasis/metabolism
• cold exposure over 30 minutes leads to greater drop in body temperature than in wild-type controls
• fasting levels of leptin are also reduced
• mice had significantly lower levels of serum leptin under either a normal chow diet (2.720 pg/ml vs 1.419 pg/ml) or a high fat diet (13.157 pg/ml vs 4.52 ng/ml)
• lower circulating levels of plasma ketone body are found whether mice are fed a chow or a high fat diet, or under fasting conditions
• levels of plasma non-esterified fatty acids are significantly lower for these mice under both normal- and high fat-diets, or under fasting conditions
• fasting plasma levels of triglycerides from mice fed a high fat diet are significantly lower than controls
• female mice have slightly higher body temperature when not fasting, or fasting after being fed a high fat diet
• oxygen consumption is 20% higher in these mice compared to controls
• mice have lower blood glucose levels than controls for 100 minutes after administration of glucose
• mice have lower blood glucose levels for an hour after administration of insulin compared to controls
• the lipolysis rate in white adipose tissue is about double that of controls

integument
N
• despite a lean phenotype, mice do not exhibit dry hair or hair loss at 10 months of age or later
• the weight of these fat pads is significantly reduced in these mice on both a chow and a high fat diet

vision/eye
N
• despite a lean phenotype, mice do not exhibit dry eyes at 10 months of age or later

• fasting plasma levels of triglycerides from mice fed a high fat diet are significantly lower Lepob homozygotes
• mice have lower blood glucose levels compared to Lepob homozygote controls for at least 125 minutes after administration of glucose
• levels of glucose are significantly higher than in wild-type mice given the same amount of glucose
• mice have lower blood glucose levels for 125 minutes after administration of insulin compared to Lepob homozygote controls
• levels of glucose are significantly higher than in wild-type mice given the same amount of insulin
