Enhanced lipid deposition with increased lipid droplet sizes of brown adipose tissue in Sqstm1tm2.1Jmos/Sqstm1tm2.1Jmos Tg(Fabp4-cre)1Rev/0 mice

homeostasis/metabolism
• at room temperature and during acute cold exposure
• in mice fed standard chow but not a high fat diet
• in mice fed standard chow or a high fat diet

adipose tissue
• in mice fed standard chow
• however, fat mass is normal in mice fed a high fat diet
• impaired nonshivering thermogenesis above brown adipose tissue treated with the selective beta-3 adrenergic receptor agonist CL-316,243

cellular
• fewer and shorter cristae displaced to the periphery with varying degrees of disorientation in the mitochondria of brown adipose tissue
• in the mitochondria of brown adipose tissue
• decreased oxidative capacity in the mitochondria of brown adipose tissue

growth/size/body
• in mice fed a high fat diet
• however, lean mass is normal in mice fed standard chow
• in mice fed standard chow or a high fat diet

liver/biliary system
• in mice fed standard chow or a high fat diet

behavior/neurological
N
• mice fed standard chow or a high fat diet exhibit normal food intake
• reduced locomotor activity (total and mean dark but not mean light)
