Reference | Model (KO/TG) | Changes in brown adipose tissue | Whole-body metabolic phenotype |
---|---|---|---|
(12) | TG FoxC2 in fat cells | Higher interscapular BAT and increased expression of C/EBPα, PPARγ, SREBP1, and metabolic rate in TG WAT | Lower HFD-induced weight gain and fat accumulation and improved glucose control |
(63) | SRC1 KO | Higher lipid infiltration and lower expression of UCP1 and PGC1α | Higher HFD-induced weight gain, reduced metabolic rate, and body temperature at 4°C |
(63) | TIF2 KO | Lower lipid infiltration and higher expression of UCP1 and PGC1α | Lower HFD-induced weight gain and fat accumulation and improved glucose control. Higher metabolic rate and body temperature at 4°C |
(14) | SRC3 KO | Lower lipid infiltration and increased mitochondrial number | Lower HFD-induced weight gain and fat accumulation and improved glucose control. Higher metabolic rate, body temperature, and muscle mitochondrial content |
(73) | p107 KO | White fat cells with multilocular lipid droplets and high UCP1 and PGC1α levels | Lower WAT mass and increased metabolic rate |
(87) | BMP7 KO | Lower BAT mass at birth | Mice are not viable after birth |
(87) | BMP7 TG | Increase in brown but not white fat mass | Higher metabolic rate and body temperature and lower weight gain |
(44) | RIP140 KO | Higher expression of UCP1 and CPT1b | Lower HFD-induced weight gain and liver fat accumulation. Higher metabolic rate |
(35) | UCP1-Wnt10b TG | Lack of functional BAT with lower expression of PGC1α and UCP1 | Blunted increase in body temperature after β-agonist stimulation |
(61) | Adipose tissue TG twist-1 | Lower expression of PGC1α and UCP1. Lower metabolic rate and mitochondrial density. Higher lipid infiltration | Higher HFD-induced weight gain and lower body temperature at night |
(61) | Twist-1+/− | Lower lipid infiltration. Higher mitochondrial number and metabolic rate | Lower HFD-induced weight gain and higher body temperature at night |
