摘要:
目标: abyiatic Acid Aciatic Acid Aciatic Acid Aciatic Acid Aciatic Aciatic Aciactiac(aa),以抑制肺部和肝纤维的影响,同时还对fibris(fibris)进行了影响。 We aimed to investigate whether AA could inhibit overpressure-induced cardiac fibrosis in spontaneous hypertension rats (SHRs).
METHOD: SHRs were treated with AA (20 mg kg day) for 12 weeks and cultured cardiac fibroblasts (CFs) were treated with Ang II (10mol/l)体外。测量氧化应激的标记,并用Sirius红色染色评估心脏纤维化的程度。使用商业测定套件测量了超氧化物歧化酶(SOD),丙二醛(MDA),活性氧香料(ROS)和谷胱甘肽(GSH)的水平。检测到胶原膜。 The expression of relative protein and mRNA was measured by Western blot and real-time PCR, respectively.
RESULTS: AA reduced systolic blood pressure, attenuated myocardial hypertrophy, reduced college deposition and the expression of collagen I and III, connective tissue growth factor, and plasminogen activator inhibitor-1,在mRNA和蛋白水平中,抑制TGF-β1表达,SMAD2/3的磷酸化以及SMAD7表达的增加。 AA降低了丙二醛和活性氧香料,同时增加了超氧化物歧化酶和谷胱甘肽的活性,并伴随着核TR的升高核因素红细胞2相关因子2(NRF2)以及血红素加氧酶(HO-1)和NAD(P)H脱氢酶[Quinone] 1(quinone] 1(NQO-1)的表达)的ANSLESTO Moreover, pretreating CFs with siRNA for Smad7 or Nrf2 both partially reversed the inhibition of AA on Ang II-induced cardiac fibrosis.
CONCLUSION: AA attenuates pressure overload-induced cardiac fibrosis via enhancing of Nrf2/HO-1 and suppressing TGF-β1/Smads磷酸化。
