The Mechanism of Yiyaobi Ⅱ Mediating KLF2 Regulation of PI3K/Akt/mTOR Pathway on the Expression and Biological Behavior of Rheumatoid Arthritis Mouse Model
摘要
Abstract
Objective:To investigate the effect of Yiyaobi Ⅱ on the expression and biological behavior of mouse model of rheumatoid arthritis by mediating KLF2 regulation of PI3K/Akt/mTOR pathway.Methods:A total of 80 Kunming mice were divided into control group,model group,Yiyaobi Ⅱ group,low dose group and high dose group.Except the control group,RA model was established by intradermal injection of Freund's complete adjuvant in the left posterior toe of the other groups.Yiyaobi Ⅱ group,low,and high dose groups were given corresponding doses of drugs by intragastric administration on the first day of successful modeling for 3 months,and control group and model group were given equal volume of normal saline.After the experi-ment,PEL,joint inflammation score and toe volume were measured.The levels of KLF2,PI3K,Akt and mTOR were determined by RT-PCR,Western blot and immunohistochemistry.Results:The PEL of the model group was lower than that of the control group,while the arthritis inflammation score and paw volume were higher than those of the control group(P<0.05).In the low-and high-dose Yiyaobi Ⅱ groups,the PEL was higher,and the arthritis inflammation score and paw volume were lower compared to the model group(P<0.05).With increasing doses of Yiyaobi Ⅱ,PEL increased,while the arthritis inflammation score and paw vol-ume decreased(P<0.05).The expression of KLF2,PI3K,Akt,and mTOR mRNA and proteins in the ankle cartilage of the model group was higher than in the control group(P<0.05).In the low-and high-dose Yiyaobi Ⅱ groups,the expression of these markers was lower than in the model group(P<0.05),with ex-pression levels decreasing as the dose increased(P<0.05).Conclusion:Yiyaobi Ⅱ has a significant thera-peutic effect on rheumatoid arthritis in mice,notably inhibiting synovitis and inflammation in the ankle carti-lage.The mechanism is associated with suppressing the activation of the KLF2-PI3K-Akt-mTOR pathway in rheumatoid arthritis.关键词
