Effect of Ermiaosan on Function of Human Fibroblast Synovial Cells Induced by TNF-α
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.
