This study explored the phytoestrogen-like effect of Siwu Decoction(SWD) and the estrogen receptor(ER)-mediated molecular mechanism based on network pharmacology and in vivo experiment. The active components and targets of SWD were retrieved from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP), and related targets of "estrogen" from GeneCards and Online Mendelian Inheritance in Man(OMIM). Cytoscape and STRING were employed to construct the protein-protein interaction(PPI) network and "chemical component-target-disease" network and core targets were identified, followed by Gene Ontology(GO) term enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment of the core targets by R software.

Along with the age growth and aging of the body, women will suffer from menopausal syndrome during menopause. In addition to the significant changes in the genital system, there are also pathological manifestations in estrogen target points including bone, nerve and cardiovascular systems, due to the imbalance of Yin and Yang.

The key proteins in PI3 K/AKT signaling pathway mediated by GPER were detected by Western blot and immunofluorescence technique.

Curcumin, a polyphenolic compound isolated from turmeric, has been shown to have anti-fibrotic effects in various organs. We and others have demonstrated that curcumin beneficially affects the development of fibrosis.

The aim of this study is to observe the effect of carnosol on cell proliferation and its estrogen receptor α and β's specific regulation and mediation mechanisms with ER positive breast cancer T47D cell.

This study is carried out to explore the antioxidant effect of carnosol in bovine aortic endothelial cells (BAECs) via ER pathway. The ER subtype specific estrogenic effect of carnosol was further demonstrated by luciferase reporter gene assay in human embryonic kidney (HEK) 293 cells.

Objective: To observe and evaluate the phytoestrogenic effects and its mechanism of psoralen in estrogen receptor (ER) alpha and beta positive T47D and ishikawa cells.
Method: The proliferation rate of T47D influenced by 1 x 10(-5) mol x L(-1) to 1 x 10(-9) mol x L(-1) psoralen and that of Ishikawa influenced by 1 x 10(-6) mol x L(-1) and 1 x 10(-7) mol x L(-1) psoralen were analyzed by MTT assay. PR mRNA expression in T47D was quantified by RT-PCR assay.

Objective: To explore the phytoestrogenic effects of ten kinds of Chinese medicine including flos carthami, radix cyathulae, radix salviae miltiorrhizae, fructus ligustri lucidi, fructus lycii, radix clycyrrhizae, herba cistanches, herba epimedii, fructus psoraleae and semen cuscutae.
Method: 240 female Kunming mice weighting 9 - 12 g were randomly divided into two main groups A and B. A group was divided into 12 small groups: 1 solvent control group, 1 diethylstilbestrol control group and 10 Chinese medicine groups.
