OBJECTIVE: To observe the effect of taurine treatment in rats with monosodium glutamate (MSG)-induced obesity. METHODS: Rats with MSG-induced obesity were administered taurine for five weeks. The Lee's index, food intake, blood pressure, body temperature, body mass index (BMI), fat weight, and triglyceride (TG), low density lipoprotein (LDL), and high density lipoprotein (HDL) levels were compared. The PGC-1α expression levels in white and brown adipose were measured using reverse transcription polymerase chain reaction and western blotting, and pathological changes in the arcuate nucleus and liver were examined. RESULTS: Compared with the model group, BMI, TG, and LDL in the high and low taurine dose groups were significantly lower, while HDL was higher. Body temperature in the taurine treatment groups was higher, and blood pressure was lower. The weight of brown fat in the taurine treatment groups was significantly higher than in the model group, while the white fat weight was significantly lower. Compared with the control group, the PGC-1α levels in white and brown adipose were higher in the taurine treatment groups and more significantly up-regulated in brown adipose. DISCUSSION: This study suggests that taurine prevents obesity in MSG-treated rats and may be closely associated with energy metabolism.
