摘要: 取单层生长状态良好的犊牛脂肪细胞,分别添加0、2.5、5、15、30、50、100 μg/mL外源牛重组脂联素(adiponectin,ADPN),培养12 h后提取总RNA,采用荧光定量PCR方法检测外源脂联素对脂肪细胞ADPN mRNA和HSL mRNA表达水平的影响。结果显示,随着ADPN添加量的增多,ADPN mRNA相对表达量呈下降趋势;添加ADPN 15 μg/mL时,HSL mRNA的表达量达到峰值,之后呈下降趋势。结果表明体外培养的脂肪细胞中ADPN mRNA表达量受自身的负调节,而添加适量的ADPN可刺激脂肪细胞HSL mRNA的表达。

Abstract: This experiement on adipocyte of calf was adopt to make primary culture,select monolayer growth well adipocyte of calf,then add concentration of the additives was as ADPN: 0,2.5,5,15,30,50,100 μg/mL, after 12 h cultivation,abstract total RNA and test the effect of ADPN on the fat cell of ADPN mRNA and HSL mRNA expression by FQ-PCR method. With increasing the addition of ADPN, expression level of ADPN mRNA decreased; the expression level of HSL mRNA in fat cell was highest when the concentration of ADPN was 15 μg/mL in cell culture media,then decreased. The results showed as follows: the ADPN mRNA expression was regulated by negative regulator itself in adipocyte culture in vitro, but the appropriate amount concentration of ADPN could stimulate adipocyte HSL mRNA expression.

Key words: adiponectin; adipocytes; ADPN mRNA; HSL mRNA
