目的:
2
二妙散(EMS)对肿瘤坏死因子(TNF)-
α
诱导的人类风湿关节炎(RA)成纤维样滑膜细胞(FLS)增殖、迁移、黏附、侵袭、分泌功能的作用及其可能机制。
方法:
2
TNF-
α
(20 μg·L
-1
)体外诱导RA患者FLS,加入不同质量浓度二妙散(0.2,0.4,0.8 g·L
-1
)作用后,分别采用噻唑蓝(MTT)比色法,transwell迁移、黏附及侵袭实验检测FLS细胞的增殖活性、迁移、黏附及侵袭能力,酶联免疫吸附测定(ELISA)检测细胞上清中白细胞介素(IL)-1
β
的含量。提取FLS中的蛋白,采用蛋白免疫印迹法(Western blot)检测磷酸化Janus激酶1(p-JAK1),p-信号转导与转录激活因子(STAT)1,p-STAT6的蛋白表达水平。
结果:
2
与空白组比较,TNF-
α
(20 μg·L
-1
)能增加FLS细胞的增殖、迁移、黏附、侵袭能力及IL-1
β
分泌(
P
<
0.01);与TNF-
α
组比较,二妙散(0.2,0.4,0.8 g·L
-1
)作用24 h对TNF-
α
诱导的FLS细胞增殖活性没有明显影响,作用24 h内还能明显降低TNF-
α
诱导升高的FLS细胞迁移、黏附、侵袭能力及分泌IL-1
β
(
P
<
0.05);与空白组比较,TNF-
α
能分别诱导p-JAK1,p-STAT1,p-STAT6在FLS中的异常升高(
P
<
0.01),0.2,0.4,0.8 mg·L
-1
的二妙散能明显降低p-JAK1,p-STAT1,p-STAT6的表达水平(
P
<
0.05,
P
<
0.01)。
结论:
2
二妙散可降低FLS细胞增殖、迁移、黏附、侵袭及IL-1
β
的分泌,而其机制可能与JAK/STAT信号通路相关。
Objective:
2
To study the effects of Ermiaosan on migration
adhesion and invasion of human fibroblast-liked synovial cells(FLS) and explore its mechanism.
Method:
2
Using the human FLS as the research object
the nontoxic concentration of FLS.FLS was determined by methyl thiazolyl tetrazolium (MTT) colorimetric assay for the follow-up experiment. The transwell migration
adhesion and transwell invasion test were used to detect the migration and adhesion of the different concentration of Ermiaosan on FLS
respectively. The expression of interleukin (IL)-1 beta of FLS supernatant was detected by enzyme linked immunosorbent assay (ELISA). Protein in FLS was extracted and protein expression levels of phosphorylated Janus kinase 1 (p-JAK1)
p-signal transducer and activator of transcription (STAT1) and p-STAT6 were detected by Western blot.
Result:
2
Compared with control group
tumor necrosis factor(TNF)-
α
(20 μg·L
-1
) increased the proliferation
migration
adhesion
invasion and the secretion of IL-1
β
of FLS (
P
<
0.01). Ermiaosan(0.2
0.4
0.8 mg·L
-1
) had no significant effect on the proliferation of FLS induced by TNF-
α
for 24 h. Within 24 h
the migration
adhesion
invasion
invasion
and secretion of IL-1
β
of FLS cells induced by TNF-
α
were also decreased significantly(
P
<
0.05
P
<
0.01). Compared with the blank group
TNF-
α
could induce abnormal elevation of p-JAK1
p-STAT1 and p-STAT6 in FLS (
P
<
0.01)
while Ermiaosan of 0.2
0.4
0.8 g·L
-1
could significantly reduce the expression levels of p-JAK1
p-STAT1 and p-STAT6 (
P
<
0.05
P
<
0.01).
Conclusion:
2
Ermiaosan can inhibit the migration
adhesion and invasion of FLS
and its mechanism may be related to the inhibition of the secretion of IL-1
β
the mechanism may be related to JAK/STAT pathway.
