Abstract:
Objective:To investigate effect of artesunate(ART)on high glucose(HG)induced trophoblast cell damage and its mechanism.Methods:Human trophoblast cells HTR-8/SVneo were separated into control group,HG group,ART low concentra-tion group,ART high concentration group and ART high concentration+lysophosphatidic acid(LPA)group.CCK-8 method was applied to detect cell viability.Flow cytometry was applied to detect cell apoptosis.ELISA was applied to detect levels of TNF-α,IL-1β and IL-10.Reagent kits were used to detect levels of lactate dehydrogenase(LDH),malondialdehyde(MDA)and superoxide dismutase(SOD).Western blot was applied to detect expressions of Bax,Bcl-2,Ras homolog gene family member A(RhoA),Rho associated coiled coil containing protein kinase(ROCK)1 and ROCK2.Results:After treatment with 0.4～1.6 μmol/L ART,activity of HTR-8/SVneo cells were increased(P<0.05).ART greatly enhanced activity of HTR-8/SVneo cells induced by HG,and cell viability was most significantly increased under 1.6 μmol/L ART treatment(P<0.05).Compared with control group,activity of HTR-8/SVneo cells,IL-10,SOD and Bcl-2 levels were reduced in HG group,apoptosis rate,TNF-α,IL-1β,LDH,MDA,Bcl-2,RhoA,ROCK1 and ROCK2 levels were increased(P<0.05).Compared with HG group,activity of HTR-8/SVneo cells,IL-10,SOD and Bcl-2 levels were increased in ART low and high concentration groups,apoptosis rate,TNF-α,IL-1β,LDH,MDA,Bcl-2,RhoA,ROCK1 and ROCK2 levels were decreased(P<0.05).Compared with ART high concentration group,activity of HTR-8/SVneo cells,IL-10,SOD and Bcl-2 levels were decreased in ART high concentration+LPA group,apoptosis rate,TNF-α,IL-1β,LDH,MDA,Bcl-2,RhoA,ROCK1 and ROCK2 levels were increased(P<0.05).Conclusion:ART can inhibit inflammatory response and oxidative stress of trophoblast cells and reduce cell apoptosis,whose mechanism may be related to inhibition of RhoA/ROCK signaling pathway.
