目的
2
探讨细胞外基质(extracellular matrix,ECM)过度沉积在肺血管重塑和肺动脉高压(pulmonary hypertension,PH)中的作用及其分子机制。
方法
2
采用不同浓度(0、1、2、5、10 μg/mL)半乳糖凝集素-3(galectin-3,Gal-3)刺激大鼠肺动脉成纤维细胞(pulmonary artery fibroblasts,PAFs)24 h,或者采用2 μg/mL Gal-3处理PAFs不同时间(0、12、24、48、72 h),酶联免疫吸附试验检测Ⅰ型胶原的蛋白水平;使用GSK-3β siRNA及β-catenin siRNA分别特异性沉默GSK-3β、β-catenin表达,qRT-PCR检测β-catenin mRNA水平,免疫印迹法检测β-catenin蛋白水平,免疫荧光染色检测β-catenin蛋白的亚细胞定位。
结果
2
Gal-3剂量和时间依赖性增加大鼠PAFs培养上清液中的Ⅰ型胶原蛋白;与对照组比较,Gal-3处理组细胞中GSK-3β磷酸化和失活,β-catenin蛋白含量增加(
F=
18.242,
P=
0.000)并从细胞质向细胞核移位。与对照组比较,Gal-3处理组或GSK-3β siRNA组均可增加β-catenin的蛋白水平,但不影响其mRNA水平;与Gal‑3处理组比较,β-catenin siRNA+Gal-3组细胞中的Ⅰ型胶原蛋白水平有所下调(
F
=9.965,
P
=0.028)。
结论
2
Gal-3通过调节GSK-3β/β-catenin信号通路增加PAFs中Ⅰ型胶原的表达,表明干预Gal-3或GSK-3β/β-catenin信号通路在预防和治疗PH方面具有潜在价值。
Objective
2
To investigate the role and molecular mechanism of excessive deposition of extracellular matrix in pulmonary vascular remodeling and pulmonary hypertension(PH).
Methods
2
Rat pulmonary artery fibroblasts(PAFs) were treated with galectin-3(Gal-3) at different concentrations(0,1,2,5,10 μg/mL) for 24 hours or 2 μg/mL Gal-3 for different periods of time(0,12,24,48,72 hours),and ELISA was used to measure the level of collagen type I. Glycogen synthase kinase-3β(GSK-3β) siRNA and β-catenin siRNA were used to specifically silence GSK-3β and β-catenin,respectively;qRT-PCR was used to measure the mRNA level of β-catenin,Western blotting was used to measure the protein level of β-catenin,and immunofluorescent staining was used to determine the subcellular localization of β-catenin.
Results
2
Gal-3 increased the level of collagen type Ⅰ in culture supernatant of rat PAFs in a dose- and time-dependent manner. Compared with the control group,the Gal‑3 treatment group had phosphorylation and inactivation of GSK-3β,a si
gnificant increase in the content of β-catenin(
F
=18.242,
P
=0.000),and the translocation of β-catenin from cytoplasm to nucleus. In addition,compared with the control group,Gal-3 treatment and GSK-3β siRNA increased the level of β-catenin and did not affect the mRNA level of β-catenin,and compared with the Gal‑3 group,the β-catenin siRNA+Gal-3 group had a reduction in the protein level of collagen type Ⅰ in cells(
F
=9.965,
P
=0.028).
Conclusion
2
Gal-3 increases the expression of collagen type I in PAFs by regulating the GSK-3β/β-catenin signaling pathway,suggesting that intervention of Gal-3 or the GSK-3β/β-catenin signaling pathway may have a potential value in the prevention and treatment of PH.
