摘要
以3、11、20mmol/L葡萄糖或在5mmol/L葡萄糖浓度时以2.5mg/L球形脂联素孵育INS-1细胞24h,RT—PCR检测PPARα、肉毒碱棕榈酸转移酶1(CPT1)和酰基辅酶A氧化酶(ACO)mRNA的表达。结果显示,随着葡萄糖浓度的升高,INS-1细胞PPARα和CPT1、ACO mRNA的表达降低(均P〈0.05),球形脂联素增加PPARα(0.945±0.153vs0.749±0.069)、CPT1(0.590±0.029vs0.388±0.037)和ACO(1.553±0.131vs1.287±0.224)mRNA的表达(均P〈0.05),可被AMP活化的蛋白激酶(AMPK)抑制剂阿糖腺苷所抑制(分别为0.360±0.113、0.248±0.037和0.942±0.303,均P〈0.05)。
INS-1 cells were treated with 3,11,20 mmol/L glucose or 2.5 mg/L globular adiponectin at the concentration of 5.5 mmoL/L glucose for 24 h. The levels of PPARα, carnitine pahnitoyltransferase I ( CPT1 ) and acyl-CoA oxidase(ACO) mRNA were detected by RT-PCR. The results showed that PPARα, CPTland ACO mRNA expressions were down-regulated with the increase of glucose concentration( all P〈0.05). Globular adiponectin increased PPARα(0. 945±0. 153 vs 0. 749±0. 069), CPTI (0. 590±0. 029 vs 0. 388±0. 037) and ACO ( 1. 553±0. 131 vs 1. 287±0. 224) mRNA expressions( all P〈0.05 ) ,which were inhibited by AMP-activated protein kinase inhibitor adenine 9-β-D-arabinfuranoside(0. 360±0.113,0.248±0. 037 and 0. 942±0. 303, respectively, all P〈0.05 ).
