الوصف: Objectives: Activation of β3-adrenoceptor (ADRB3) is essential in the process of human adipose tissue browning, but obese subjects suffered from reduced ability of brown adipose tissue activation. The present study aims to detect the adipocyte ADRB3 expression in overweight individuals and the relationship between adipocyte ADRB3 expression and adiposity in adults. Methods: Visceral adipose tissue samples were obtained from 85 subjects who underwent abdominal surgery. ADRB3 mRNA and protein expression levels in mature adipocytes and adipose tissue stromal vascular cells were examined by quantitative real-time PCR and Western blot assay, respectively. UCP-1mRNA expression levels in mature adipocytes were examined by quantitative real-time PCR. Results: The data revealed that ADRB3 mRNA (p = 0.021) and protein (p = 0.025) expression levels in mature adipocytes were significantly higher in the normal-weight than in the overweight group. Similar results were also found for ADRB3 mRNA (p = 0.041) and protein (p = 0.025) expressions of stromal vascular cells. An inverse correlation was verified between mature adipocyte ADRB3 mRNA expression and BMI (r = –0.362, p = 0.012). UCP-1 mRNA expression levels in mature adipocytes were higher in the normal-weight group compared with the overweight group (p = 0.045). Conclusion: Adipocyte ADRB3 expression levels were down-regulated before the onset of obesity, which indicated that the reduction of ADRB3 expression might be the cause of compromised adipose tissue browning and obesity rather than the result. Thus, the interference of the ADRB3 pathway in adipocytes may provide a potential treatment target for obesity.
