According to the classical signal transduction pathway of estrogen, we use Luciferase reporter gene to screen phytoestrogen form Selaginella tamariscina, Pinus massoniana Lamb, Corallodiscus flabellate, Dryopteris sublaeta Ching et Hsu and Leonurus heterophyllus. In this study,the pβgal-Control vector, the pERE-TAL-luc vector, the pCNX2-hERα/pCNX2-hERβvector were transfected into HEK293 cell line. If the components in the herbs combine with the ER, then it could induce the expression of reporter gene controlled by ERE.

根据体内的雌激素信号转导途径，我们选用了以luc为报告基因、ERE为调控序列的重组报告基因载体pERE-TAL-luc，并将其与重组人ERα(humanERα，hERα)表达载体pCXN2-hERα和重组人ERβ(humanERβ，hERβ)表达载体pCXN2-hERβ共转染ER阴性细胞系，建立了靶向ERα或ERβ的细胞水平药物筛选模型，结合小鼠子宫增重实验，对卷柏、松针、益母草、石胆草及贯众等5种中药的植物雌激素作用进行了研究，以期为临床防治更年期综合症等提供准确、科学的实验基础。
