Effect of Danggui Niantongtang on Autophagy and Apoptosis of Rheumatoid Arthritis Fibroblast-like Synoviocyte
To explore the effect of Danggui Niantongtang (DGNTT) on cell apoptosis and autophagy in rheumatoid arthritis (RA) fibroblast-like synoviocytes (FLS).
Method
2
RA-FLS were isolated and cultured from the synovial tissue of RA patients. The cells were treated with 10% blank serum (blank control group), 10% sera containing low, medium and high doses of DGNTT. Wound healing assa and cell invasion test were applied to observe the effect of RA-FLS invasion technique. The apoptosis and autophagy level of RA-FLS cells was detected by Hoechst33342 method and monodansylcadaverine (MDC) staining. The mRNA and protein expression levels of B cell lymphoma-2 (Bcl-2), Bcl-2 associated X protein (Bax), microtubule-associated protein 1 light chain 3 (LC3), autophagy key molecular yeast Atg6 homolog 1 (Beclin1) were detected by Real-time fluorescence quantitative polymerase chain reaction(Real-time PCR)and Western blot.
Result
2
Compared with the blank control group,each dose of serum could slow down the wound healing and significantly Reduce the number of RA-FLS cells invading the lower chamber(
P<
0.01),the mRNA and protein expression levels of Bcl-2,LC3,Beclin1 were significantly decreased(
P<
0.01), and Bax were significantly increased(
P<
0.01). Hoechst33342 results showed that low, medium and high doses DGNTT could promote RA-FLS cell apoptosis. After MDC staining,autophagosome in low, medium and high doses DGNTT decreased significantly(
P<
0.01).
Conclusion
2
Danggui Niantongtang can effectively inhibit the proliferation of fibroblast-like synoviocytes. Its mechanism may be related to promote apoptosis and inhibit autophagy of fibroblast-like synoviocytes.
