摘要
Abstract
Objective To investigate the effects of Guilu Erxian Jiao(GLJ)and its disassembled formulations on the autophagy mecha-nism of degenerative chondrocytes via the AMPK/mTOR signaling pathway.Methods Wild-type and mTOR KO mouse chondrocytes were cultured in vitro using enzyme digestion.IL-1β was used to induce F2 generation chondrocytes to establish a model of degenerative chondrocytes.The mouse chondrocytes were randomly divided into blank group,model group,Turtle and Deer group,Turtle Shell group,Deer Antler group,CKO group,Turtle and Deer+CKO group,Turtle Shell+CKO group,and Deer Antler+CKO group.Af-ter 24 h of serum intervention,chondrocyte viability was detected by CCK-8 method;immunofluorescence method was used to detect chondrocyte PARP expression;laser confocal microscopy was used to observe chondrocyte LC3B fluorescence intensity;qPCR method was used to detect chondrocyte AMPK,mTOR,COL2A1 mRNA expression;Western-Blot was used to detect chondrocyte AMPK,p-AMPK,mTOR,p-mTOR,COL2A1 protein expression.Results Compared with the model group,all intervention groups showed in-creased cell viability,enhanced LC3B fluorescence intensity,reduced PARP average fluorescence intensity,increased AMPK and COL2A1 protein and mRNA expression,and decreased mTOR and mRNA expressions(P<0.05).Compared with the GLJ group,the GLJ+CKO group exhibited higher cell viability,increased LC3B fluorescence intensity,decreased PARP fluorescence intensity,in-creased AMPK,COL2A1 and mRNA expressions,elevated p-AMPK protein expression,reduced mTOR and mRNA expressions,and decreased p-mTOR protein expression(P<0.05).Compared with the GB group,the LJ group exhibited higher cell viability,reduced LC3B fluorescence intensity,increased PARP fluorescence intensity,decreased AMPK and mRNA expression,increased COL2A1 and mRNA expression,decreased p-AMPK protein expression,and increased mTOR and mRNA expressions(P<0.05).The GB+CKO group showed enhanced cell viability,increased LC3B fluorescence intensity,decreased PARP fluorescence intensity,elevated AMPK and COL2A1 protein and mRNA expression,increased p-AMPK protein expression,and reduced mTOR protein,mTOR mRNA,and p-mTOR protein expressions(P<0.05).Compared with the LJ group,the LJ+CKO group showed improved cell viability,increased LC3B fluorescence intensity,decreased PARP fluorescence intensity,elevated AMPK and COL2A1 protein and mRNA expression,in-creased p-AMPK protein expression,and reduced mTOR protein,mTOR and mRNA,and p-mTOR protein expressions(P<0.05).Conclusion Guiban enhances chondrocyte autophagy and inhibits apoptosis,while Lujiao promotes chondrocyte proliferation and extra-cellular matrix(ECM)synthesis.GLJ demonstrates superior efficacy compared to Guiban and Lujiao,with its mechanism linked to the AMPK/mTOR pathway activation.关键词
