目的:探讨维立西呱对缺氧诱导的HL-1小鼠心房肌细胞纤维化的影响及机制研究。方法:在不同时间(0、12、24、48 h)和不同浓度的维立西呱(0、5、10、20、50 μmol/L)的条件下,将HL-1细胞置于细胞缺氧箱进行造模,蛋白印迹检测纤维化蛋白I型胶原蛋白(Collagen Ⅰ)、Ⅲ型胶原蛋白(Collagen Ⅲ)、ɑ-平滑肌肌动蛋白(ɑ-SMA)表达水平。模型建立成功后,将HL-1细胞分为对照组、缺氧组和缺氧+维立西呱组,蛋白印迹检测Collagen Ⅰ、Collagen Ⅲ、ɑ-SMA蛋白以及可溶性鸟苷酸环化酶(sGC)-环磷酸鸟苷(cGMP)-蛋白激酶G1(PKG1)信号通路中可溶性鸟苷酸环化酶1/ɑ3(GUCY1A3)、PKG1、血管扩张剂刺激磷蛋白(VASP)和磷酸化VASP(p-VASP)蛋白表达水平。结果:与缺氧0 h相比,缺氧12 h时HL-1细胞Collagen Ⅰ、Collagen Ⅲ、ɑ-SMA蛋白表达水平最高(t=0.8312,P>0.05;t=3.102,P<0.05;t=6.403,P<0.05)。在缺氧12 h条件下,与维立西呱浓度0 μmol/L相比,维立西呱浓度为50 μmol/L时,Collagen Ⅰ、Collagen Ⅲ、ɑ-SMA蛋白表达明显下降(t=14.10、6.440、9.264,均P<0.05)。与对照组相比,缺氧组Collagen Ⅰ、Collagen Ⅲ、ɑ-SMA蛋白表达均明显升高(t=4.648、6.643、4.551,均P<0.05)。与缺氧组相比,缺氧+维立西呱组Collagen Ⅰ、Collagen Ⅲ、ɑ-SMA蛋白表达均明显降低(t=4.717、4.771、3.367,均P<0.05)。与对照组相比,缺氧组GUCY1A3、PKG1、p-VASP 蛋白表达均明显下降(t=16.56、8.492、7.430,均P<0.05)。与缺氧组相比,缺氧+维立西呱组GUCY1A3、PKG1、p-VASP蛋白表达均明显升高(t=5.876、3.006、4.637,均P<0.05)。3组比较,VASP蛋白表达无显著差异(F=0.5671,P>0.05)。结论:维立西呱可以减轻缺氧诱导的HL-1细胞的纤维化,sGC-cGMP-PKG1信号通路可能参与其中并发挥作用。

Objective: To investigate the effect and mechanism of Vericiguat on hypoxia-induced fibrosis in HL-1 mouse atrial myocytes. Methods: At different times (0, 12, 24, 48 hours) and different concentrations of Vericiguat(0, 5, 10, 20, 50 μmol/L), HL-1 cells were placed in a cell hypoxia chamber for modeling and the expressions of fibrotic proteins Collagen Ⅰ, Collagen Ⅲ, and ɑ-smooth muscle actin(ɑ-SMA) were detected by Western blotting. After the model was successfully established, HL-1 cells were divided into Control group, Hypoxia group and Hypoxia+Vericiguat group. The expressions of Collagen Ⅰ, Collagen Ⅲ, ɑ-SMA, as well as soluble guanylate cyclase 1/alpha 3 (GUCY1A3), protein kinases G1(PKG1), vasodilator stimulated phosphoprotein (VASP), and phosphorylation VASP (p-VASP) in soluble guanylate cyclase (sGC) - cyclic guanosine monophosphate (cGMP) - protein kinase G1(PKG1) signaling pathway were detected by Western blotting. Results: Compared with hypoxia for 0 h, the expressions of Collagen Ⅰ, Collagen Ⅲ, and ɑ-SMA in HL-1 cells at hypoxia for 12 h were the highest (t=0.8312, P>0.05; t=3.102, P<0.05; t=6.403, P<0.05). Under hypoxia for 12 h, compared with 0 μmol/L Vericiguat, the expressions of Collagen Ⅰ, Collagen Ⅲ, and ɑ-SMA decreased significantly when the concentration of Vericiguat was 50 μmol/L (t=14.10, 6.440, 9.264, all P<0.05). Compared with the Control group, the expressions of Collagen Ⅰ, Collagen Ⅲ, and ɑ-SMA in the Hypoxia group were significantly increased (t=4.648, 6.643, 4.551, all P<0.05). Compared with the Hypoxia group, the expressions of Collagen Ⅰ, Collagen Ⅲ, and ɑ-SMA in the Hypoxia+Vericiguat group were significantly decreased (t=4.717, 4.771, 3.367, all P<0.05). Compared with the Control group, the expressions of GUCY1A3, PKG1, and P-VASP in the Hypoxia group were significantly decreased (t=16.56, 8.492, 7.430, all P<0.05). Compared with the Hypoxia group, the expressions of GUCY1A3, PKG1, and p-VASP in the Hypoxia+Vericiguat group were significantly increased (t=5.876, 3.006, 4.637, all P<0.05). There was no significant difference in VASP protein expression among the three groups (F=0.5671, P>0.05). Conclusion:Vericiguat can reduce hypoxia-induced fibrosis in HL-1 cells, and sGC-cGMP-PKG1 signa-ling pathway may be involved and play a role in this process.
