Abstract:
Objective:To explore the effect of Bushen Qiangjin Jiaonang(補腎強筋膠囊,BSQJJN)medicated serum on autophagy in knee osteoarthritis(KOA)chondrocyte model based on the adenosine monophosphate activated protein kinase(AMPK)/mammalian target of rapamycin(mTOR)pathway.Methods:The human primary chondrocytes cultured in vitro were divided into normal group,model group,BSQJJN group,and AMPK inhibitor group.The chondrocytes in normal group were intervened with 10% blank serum,the ones in model group with 10% blank serum and 10 ng/mL interleukin-1β(IL-1β),the ones in BSQJJN group with 10% BSQJJN medicated serum and 10 ng/mL IL-1β,and the ones in AMPK inhibitor group with 10% BSQJJN medicated serum,10 ng/mL IL-1β and 10 μmol/L Dorsomorphin(an AMPK inhibitor).After 24-hour intervention,the chondrocyte proliferation rate,chondrocyte apoptosis rate,and chondrocyte autophagy rate were detected by CCK-8 assay,annexin V-fluorescein isothiocyanate/propidium iodide(FITC/PI)double staining,and dansyl cadaverine method,respectively.Furthermore,the mRNA expression levels of Beclin1,microtubule-associated protein 1 light chain 3B(LC3B),and UNC-51 like autophagy activating kinase 1(ULK1)were detected by real-time fluorescence quantitative PCR technology,and the protein expression levels of Beclin1,LC3B-I,LC3B-II,ULK1,phospho-AMPKα(p-AMPKα),and phospho-mTOR(p-mTOR)were detected by using Western blot.Results:①The chondrocyte proliferation rate.The chondrocyte proliferation rate was lower in model group compared to normal group(P=0.000),and was higher in BSQJJN group compared to model group(P=0.019),and was lower in AMPK inhibitor group compared to BSQJJN group(P=0.002).②The chondrocyte apoptosis rate.The chondrocyte apoptosis rate was higher in model group compared to normal group(P=0.000),and was lower in BSQJJN group compared to model group(P=0.000),and was higher in AMPK inhibitor group compared to BSQJJN group(P=0.000).③The chondrocyte autophagy rate.The chondrocyte autophagy rate was lower in model group compared to normal group(P=0.000),and was higher in BSQJJN group compared to model group(P=0.000),and was lower in AMPK inhibitor group compared to BSQJJN group(P=0.000).④The mRNA expression levels of chondrocyte autophagy-related genes.The mRNA expression levels of Beclin1,LC3B and ULK1 were lower in model group compared to normal group(P=0.002,P=0.001,P=0.003),and were higher in BSQJJN group compared to model group(P=0.008,P=0.005,P=0.012),and were lower in AMPK inhibitor group compared to BSQJJN group(P=0.000,P=0.038,P=0.004).⑤The protein expression levels of chondrocyte autophagy-related genes.The protein expression levels of Beclin1,ULK1,p-AMPKα and the ratio of LC3B-Ⅱto LC3B-Ⅰwere lower,while the protein expression level of p-mTOR was higher in model group compared to normal group(P=0.028,P=0.019,P=0.007,P=0.044,P=0.025).The protein expression levels of Beclin1,ULK1,p-AMPKα and the ratio of LC3B-Ⅱto LC3B-Ⅰwere higher,while the protein expression level of p-mTOR was lower in BSQJJN group compared to model group(P=0.004,P=0.048,P=0.040,P=0.043,P=0.031).The protein expression levels of Beclin1,ULK1,p-AMPKα and the ratio of LC3B-Ⅱto LC3B-Ⅰwere lower,while the protein expression level of p-mTOR was higher in AMPK inhibitor group compared to BSQJJN group(P=0.032,P=0.005,P=0.035,P=0.047,P=0.033).Conclusion:BSQJJN medicated serum may up-regulate the autophagy level of KOA chondrocyte model through the AMPK/mTOR pathway,thereby delaying the progression of KOA.
