Endogenous protein marking method used for Chip-seq genome-wide binding spectrum

The invention relates to an endogenous protein marking method applied to genome-wide binding spectrum analysis. The method comprises the steps of designing sgRNA for upstream and downstream 50bp regions of an encoding termination site of an NCOA1 gene; verifying cutting efficiency of sgRNA mediated Cas9 by an experiment; building an anti-estrogen therapy tolerant MCF-7 breast cancer cell model; by utilizing a CRISPR/Cas9 homologous recombination technology, selecting and using effective sgRNA and DNA donors, and introducing a Flag tag in the 3' end of the ER alpha co-transcription factor NCOA1 gene; and establishing a stable cell line with the Flag tag. Compared with the prior art, the method has the advantages that gene editing is performed by utilizing the CRISPR/Cas9 technology, so that the tag insertion efficiency of the gene editing is greatly improved; more importantly, chromatin structure parameters are introduced for designing sgRNA, so that effective cutting of Cas9 at a target site of a genome is ensured; and positive clone screening is performed by adopting DNA sequencing and RT-PCR sequencing methods, so that the positive clone identification step is simplified and the manpower and material resources for screening are reduced.

Method of treating estrogen responsive breast cancer

InactiveUS20050002900A1Inhibit estradiol productionLower estrogen levelsOrganic active ingredientsPeptide/protein ingredientsTreatment choicesSide effect
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.

Hormonal implants treatment of the breast cancer

An improved method and products for the hormonal treatment of breast cancer by breast implants of anti-estrogens and steroid hormones in formulations as fused with a lipoid carrier or encapsulated in microcapsules or in Silastic capsules is provided. Such breast implants renders a constant slow-release of their contents to the breast tissue for extended periods by biodegradation and diffusion. It facilitates higher breast tissue concentrations of anti-estrogen and hormonal compositions. Because of their high concentration in the breast and lower systemic distribution, tumor control is much improved and the their systemic toxicity is minimized. An added beneficial effect of these breast implants on breast cancer is mediated by the inhibition of hypothalamic-pituitary LHRH, FSH and LH secretion by these composition's systemic contents. It is also an effective prophylaxis against breast cancer. Furthermore, it reduces the cost of hormonal treatment of breast cancer. Anti-estrogen hormonal implants to the breast as concomitant hormonal treatment with conventional radiation therapy also facilitates improved tumor control and cure rates of breast cancer.

Antiestrogenic glyceollins suppress human breast and ovarian carcinoma proliferation and tumorigenesis

InactiveUS20080200537A1Preventing minimizing development growthBiocideAnimal repellantsDiseaseStress induced
The flavonoid family of phytochemicals, particularly those derived from soy, has received attention regarding their hormonal activity and their effects on human health and disease. The types and amounts of these compounds in soy and other plants are controlled by both constitutive expression and stress-induced biosynthesis. The health benefits of soy may therefore be dependent upon the amounts of the various hormonally active phytochemicals present. We have identified increased biosynthesis of the isoflavonoid phytoalexin compounds, Glyceollins I, II and III, in soy plants grown under stressed conditions (elicited soy), which exhibit marked anti-estrogenic effects on ER function. Here we demonstrate that specific glyceollins, isolated from elicited soy, displayed anti-estrogenic activity, suppressing basal and estrogen stimulated colony formation of ER-positive estrogen dependent breast cancer cells and inhibiting ER-dependent gene expression of progesterone receptor (PgR) and stromal derived factor-1 (SDF1 / CXCL12). Examining the effects of glyceollin on in vivo tumor formation / growth we demonstrate the ability of glyceollins to significantly suppress basal and estrogen-stimulated tumor growth of ER-positive MCF-7 breast and BG-1 ovarian carcinoma cells in ovariectomized female nude mice. We further demonstrate that the effects of glyceollins on suppression of tumor growth correlate with inhibition of estrogen stimulated PgR expression. In contrast to the uterotropic activity of tamoxifen the glyceollins displayed no uterine agonist activity. The Glyceollin (I-III) compounds may represent an important component of the health effects of soy as well as represent novel anti-estrogens useful in the prevention or treatment of breast and ovarian carcinoma.
