中文摘要:
      目的:探讨非诺贝特(fenofibrate)对血管紧张素Ⅱ(AngⅡ)诱导的肥大心肌细胞的抑制作用及对FoxO1 表达的影响。方法:首 先采用AngⅡ诱导心肌细胞肥大,将细胞分为三组:对照组:未给予任何干预;心肌细胞肥大组:AngⅡ(10-7 mol/L)刺激细胞;治 疗组:先给予fenofibrate (10-5 mol/L),30min 后AngⅡ(10-7 mol/L)刺激细胞。应用蛋白免疫印迹法(western-blotting) 和实时定量 PCR 法(real time PCR)检测各组细胞中转录因子FoxO1 的蛋白质及mRNA 含量,心肌细胞肥大的判断使用脑钠肽(brain natriuret ic pepide BNP)。结果:心肌细胞肥大组的FoxO1 表达较对照组明显降低,而治疗组的FoxO1 表达较心肌肥大组明显升高。结论:非 诺贝特可能通过上调FoxO1 表达,从而抑制心肌细胞肥大。
英文摘要:
      Objective: To investigate effect of fenofibrateon on myocardial hypertrophy induced by angiotensin II (Ang II) and transcription factor FoxO1 expression for theoretical bases of preventing and treating myocardial hypertrophy. Methods: H9C2 cells were divided into 3 groups: nomal control group; hypertrophy group: cells were stimulated by AngⅡ (10-7 mol/L); treatment group:cells were treated with fenofibrate (10-5 mol/L), 30 min before adding AngⅡ (10-7mol/L). The method of western-blotting and real time PCR were adopted to detect the FoxO1 expression. Brain natriuretic pepide (BNP) was the symbol of cardiac myocyte hypertrophy. Results: The mRNA and protein level of FoxO1 decreased significantly in the hypertrophy group compared with that in the normal control and treatment group. Conclusion: Fenofibrate inhibits cardiac myocyte hypertrophy, upregulates the expression of FoxO1.
