目的
2
探讨淫羊藿苷(icariin,ICA)对骨关节炎(osteoarthritis,OA)软骨细胞功能的影响及其机制。
方法
2
用不同浓度(0.1、0.5、1.0、5.0和10.0 μmol/L)ICA处理软骨细胞后,采用噻唑蓝(methylthiazolydiphenyl-tetrazolium,MTT)法检测软骨细胞活力,选择最适浓度的ICA进行后续实验。利用白细胞介素-1β(interleukin-1β,IL-1β;10 ng/mL)刺激软骨细胞24 h构建OA细胞模型,用最适浓度1 μmol/L
ICA处理细胞。采用实时荧光定量聚合酶链反应(quantitative real-time polymerase chain reaction,RT-qPCR)检测微小RNA-29c(microRNA-29c,miR-29c)的表达水平,蛋白免疫印迹(Western blot,WB)检测Ⅱ型胶原α1链(collagen type Ⅱ alpha 1 chain,COL2A1)蛋白的表达水平,酶联免疫吸附试验(enzyme-linked immunosorbent assay,ELISA)检测细胞培养上清液中基质金属蛋白酶3(matrix metalloproteinase 3,MMP-3)、肿瘤坏死因子α(tumor necrosis factor α,TNF-α)水平,流式细胞术检测细胞凋亡水平。生物信息学网站预测miR-29c的靶基因,采用双荧光素酶报告基因实验验证miR-29c与COL2A1之间的靶向结合作用。通过挽救实验阐明ICA对OA炎症反应及细胞凋亡的影响及作用机制。
结果
2
与Control组相比,IL-1β组软骨细胞上清液中MMP-3(
P<
0.001)和TNF-α(
P<
0.001)含量明显增加,COL2A1的表达水平明显降低(
P<
0.001),细胞凋亡率明显增加(
P<
0.001);与IL-1β组相比,ICA处理组中软骨细胞上清液中MMP-3(
P=
0.001
、P<
0.001)和TNF-α(
P<
0.001
、P<
0.001)含量明显减少,COL2A1的表达水平明显升高(
P<
0.001
、P<
0.001),细胞凋亡率明显降低(
P<
0.001
、P<
0.001)。与Control组相比,IL-1β组软骨细胞中miR-29c表达水平明显上调(
P<
0.001),而ICA处理则明显降低miR-29c表达水平(
P<
0.001)。与miR-NC组相比,miR-29c mimic组中软骨细胞上清液中MMP-3(
P<
0.001)和TNF-α(
P<
0.001)含量明显增加,COL2A1的表达水平显著降低(
P=
0.001),细胞凋亡率显著增加(
P<
0.001),而miR-29c inhibitor组则得到相反的结果。TargetScan7.1数据库显示miR-29c与COL2A1存在结合位点。双荧光素酶报告基因实验表明,miR-29c mimic明显抑制了野生型COL2A1载体的荧光素酶活性(
P
<
0.001),而突变型的荧光素酶活性不受影响(
P
=0.152)。敲低COL2A1可部分逆转下调miR-29c对软骨细胞中MMP-3(
P<
0.001)和TNF-α(
P<
0.001)分泌量,COL2A1蛋白表达水平(
P<
0.001)以及细胞凋亡率(
P<
0.001)的影响。ICA处理可减轻过表达miR-29c对软骨细胞中MMP-3(
P<
0.001)和TNF-α(
P<
0.001)分泌量、COL2A1蛋白表达水平(
P
=0.009)以及细胞凋亡率(
P<
0.001)的影响。
结论
2
ICA能减轻IL-1β诱导的软骨细胞炎症因子的分泌和细胞凋亡的发生,其作用机制可能与miR-29c/COL2A1轴有关。
Objective
2
To investigate the effect of icariin(ICA) on chondrocyte function in osteoarthritis(OA) and its mechanism.
Methods
2
After chondrocytes were treated with different concentrations of ICA(0.1,0.5,1.0,5.0,10.0 μmol/L),methylthiazolydiphenyl-tetrazolium(MTT) assay was used to measure the viability of chondrocytes,and then the optimal concentration of ICA was selected for subsequent experiments. Chondrocytes were stimulated by interleukin-1β(IL-1β,10 ng/mL) for 24 hours to establish a cell model of OA, and then the cells were treated with ICA at the optimal concentration of 1 μmol/L. Quantitative real-time polymerase chain reaction(RT-qPCR) was used to measure the expression level of microRNA-29c(miR-29c);Western blot was used to measure the protein expression level of collagen type Ⅱ alpha 1 chain(COL2A1); Enzyme-linked immunosorbent assay(ELISA) was used to measure the levels of matrix metalloproteinase-3(MMP-3) and tumor necrosis factor-α(TNF-α) in the supernatant of cell culture; flow cytometry was used to measure cell apoptosis rate. Bioinformatics websites were used to predict the target genes of miR-29c, and dual-luciferase reporter assay was used to verify the targeted binding between miR-29c and COL2A1. Functional rescue experiments were used to clarify the effect of ICA on inflammatory response and cell apoptosis in OA and its mechanism of action.
Results
2
Compared with the control
group,the IL-1β group had significant increases in the content of MMP-3(
P<
0.001) and TNF-α(
P<
0.001) in chondrocyte supernatant, a significant reduction in the expression level of COL2A1(
P<
0.001),and a significant increase in cell apoptosis rate(
P<
0.001). Compared with the IL-1β group, the ICA treatment group had significant reductions in the content of MMP-3(
P
=0.001;
P<
0.001) and TNF-α(
P<
0.001;
P<
0.001) in chondrocyte supernatant, a significant increase in the expression level of COL2A1(
P<
0.001;
P<
0.001),and a significant reduction in cell apoptosis rate(
P<
0.001;
P<
0.001). Compared with the control group, the IL-1β group had a significant increase in the expression level of miR-29c in chondrocytes(
P<
0.001), while ICA treatment significantly reduced the expression level of miR-29c(
P<
0.001). Compared with the control group,the miR-29c mimic group had significant increases in the content of MMP-3(
P<
0.001) and TNF-α(
P<
0.001) in chondrocyte supernatant,a significant reduction in the expression level of COL2A1(
P
=0.001),and a significant increase in cell apoptosis rate(
P<
0.001);however, opposite results were obtained for the miR-29c inhibitor group. TargetScan7.1 database showed the existence of binding sites between miR-29c and COL2A1. Dual-luciferase reporter assay showed that miR-29c mimic significantly inhibited the luciferase activity of wild-type COL2A1 vector(
P
<
0.001),but with no influence on the luciferase activity of mutant COL2A1 vector(
P
=0.140). Knockdown of COL2A1 could partially reverse the effect of downregulated miR-29c on the secretion of MMP-3(
P<
0.001) and TNF-α(
P<
0.001), the protein
expression level of COL2A1(
P<
0.001), and cell apoptosis rate(
P<
0.001) in chondrocytes. ICA treatment could alleviate the influence of miR-29c overexpression on the secretion of MMP-3(
P<
0.001) and TNF-α(
P<
0.001), the protein expression level of COL2A1(
P<
0.001), and the apoptosis rate(
P<
0.001) of chondrocytes.
Conclusion
2
ICA can alleviate the secretion of inflammatory cytokines and the apoptosis of chondrocytes induced by IL-1β, which may be associated with the miR-29c/COL2A1 axis..
