摘要
目的:在系统性硬皮病(SSc)模型小鼠上研究刺山柑乙醇提取物乳膏对Notch通路中重要蛋白Notch1、DLL1和ADAM17的调控作用。方法:给予刺山柑乙醇提取物乳膏冶疗SSc模型小鼠(模型应用BALB/c小鼠皮下注射博莱霉素4 w建立)8 w。小鼠皮肤组织中Notch1 mRNA和蛋白的表达分别采用实时荧光逆转录PCR(qPCR)和免疫组化法测定,DLL1和ADAM17含量采用ELISA法测定。结果:过表达的Notch1 mRNA和蛋白可被450、900 mg·kg^(-1)刺山柑乙醇提取物乳膏抑制,DLL1和ADAM17可被900mg·kg^(-1)刺山柑乙醇提取物乳膏抑制。结论:SSc小鼠受损皮肤Notch通路中过表达的Notch1、DLL1和ADAM17可被刺山柑乙醇提取物乳膏抑制,提示其对SSc Notch通路的过度激活有一定抑制作用。
Objective:To explore the regulation effects of capparis spinosa ethanolic extract cream on expressions of Notch1,DLL1 and ADAM17 in Notch pathway in Systemic Sclerosis(SSc)mice.Methods:SSc modelmice were treated with capparis spinosa ethanolic extract cream(the model was established by subcutaneous injection of bleomycin for 4 w in BALB/c mice)for 8 w.The mRNA expression of Notch1 and protein in mouse skin were detected by real-time reverse transcriptase PCR(qPCR)and immunohistochemical method,respectively.The contents of DLL1 and ADAM17 were measured by ELISA in skin tissue.Results:The mRNA and protein expression of Notch1 were inhibited by 450 and 900 mg·kg^(-1) capparis spinosa ethanolic extract cream and DLL1 and ADAM17 were inhibited by 900 mg·kg^(-1) capparis spinosa ethanolic extract cream.Conclusion:Capparis spinosa ethanolic extract cream could inhibit the Notch pathway in damaged skin of SSc mice by down-regulating the expressions of Notch1,DLL1 and ADAM17,suggesting that the SSc Notch pathway overactivation could be inhibited to some extent.
