The present invention is directed to a method of treating estrogen responsive breast cancer in an individual comprising administering to an individual a therapeutically effective estradiol inhibiting amount of interferon gamma (IFN-γ) and/for a tumor necrosis factor (TNF) antagonist and/or an interleukin-1 (IL-1) antagonists. The invention is based upon the surprising discovery that IFN-γ and/or a tumor necrosis factor (TNF) antagonist and/or an interleukin-1 (IL-1) antagonists inhibit estradiol production in human adipocytes. This discovery is not only important because it allows for the treatment and/or prevention of estrogen dependent breast cancer using IFN-γ, TNF antagonists or IL-1 antagonist each alone or in combination, but also because IFN-γ and/or TNF antagonists and/or IL-1 antagonists can be used in conjunction with standard anti-estrogen therapy, e.g., tamoxifen and/or aromatase inhibitor, to result in lower estrogen levels than seen with standard anti-estrogen therapy alone. Moreover, the ability to lower estrogen levels by means of the present invention, when combined with standard anti-estrogen therapy, provides an important therapeutic option in that it allows the dose of the anti-estrogen to be reduced, reducing the likelihood of side effects and complications commonly seen with anti-estrogen therapy.

The present disclosure describes a study of estrogenic activity present in various plant species, selectively inducing some but not all estrogenic responses in the uterus. Prepubertal female rats were treated sequentially with various extracts or decoctions of different plant species or its vehicle, followed 1 h later by treatment with estradiol-17β (E) or its solvent. Uteri were excised under anesthesia and histologically processed for eosinophil quantification and morphometric evaluation of various uterine responses to estrogen, at 6 or 24 h after hormone or vehicle treatment. Besides extracts or decoctions, pure phytoestrogens were also used. Additionally, human mammary cancer cells MCF-7 or MDAMB-231 were cultured in presence of the extract (or decoction), E, both or solvent and cell proliferation was evaluated. Various extracts or decoction displayed selective estrogenic and/or antiestrogenic action for some but not all parameters of estrogen stimulation in the uterus and inhibited growth of human mammary cells in culture or antagonized the estrogen-induced increase in their growth. Present results reveal, for the first time, a dissociation of responses to estrogen by phytoestrogens, suggesting its possible therapeutic application as estrogenic compounds not inducing cell proliferation and reveal the anticancerous effect of some of the extracts with possible therapeutic relevance. The dissociation of responses to estrogen additionally suggest therapeutic applications in estrogen-related diseases (for instance, premenstrual syndrome, endometriosis, etc.); the inhibition of eosinophil degranulation suggest an application in diseases related to eosinophils (hypereosinophilic syndrome, allergic and hypersensitivity diseases).

The present invention relates to a method for the prevention and treatment of postmenopausal syndrome containing the step of administering a pharmaceutically effective dose of the Aceriphyllum rossii or its fractions to a subject. The present inventors confirmed that the Aceriphyllum rossii extract or its fractions of the invention prepared by using water, alcohol or a mixed solvent thereof could promote the expression of the promoter containing estrogen responsive element (ERE) and accelerated the growth of MCF-7, the human breast tissue originated cell line, suggesting that they had estrogen activity. The inventors further confirmed that the extract or its fractions of the invention had the effect of promoting osteocyte differentiation, so that they could be effectively used for the prevention and treatment of postmenopausal syndrome such as hot flush, osteoporosis and phlebothrombosis caused by estrogen deficiency.
