Summary of "Mammary cancer risk and serum lipid profile of rats supplemented with pomegranate seed oil and bitter melon extract."

The objective of the present study was to determine the influence of dietary supplementation with pomegranate seed oil (PSO) and/or an aqueous extract of dried bitter melon fruits (BME) on breast cancer risk and fatty acid profile in serum of female rats with chemical carcinogen-inflicted mammary tumours. Sprague-Dawley rats (n = 96) were fed control diet or experimental diets supplemented with 0.15 ml PSO/day, BME or jointly PSO and BME. After 21 weeks mammary tumours were subjected to histopathological examination and in serum fatty acids, 8-isoprostaglandin F content and indices of desaturases activity were analysed. Supplementation of the diet with PSO and BME did not inhibit the breast cancer formation. Conjugated linolenic acids (CLnA), present in PSO, were converted into cis-9, trans-11 conjugated linoleic acid (CLA), however, its content was lower in groups treated with a carcinogen. A similar tendency was observed for the content of SFA, MUFA, PUFA, 8-iso PGF and the activity of Δ-desaturase. Enhanced pro-carcinogenic effect of 7,12-dimethylbenz[a]anthracene (DMBA), caused by applied supplements, may be a result of their influence on DMBA metabolism.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the MAMMARY GLAND in animals (MAMMARY GLANDS, ANIMAL).

A group of fatty acids, often of marine origin, which have the first unsaturated bond in the third position from the omega carbon. These fatty acids are believed to reduce serum triglycerides, prevent insulin resistance, improve lipid profile, prolong bleeding times, reduce platelet counts, and decrease platelet adhesiveness.

A synthetic retinoid that is used orally as a chemopreventive against prostate cancer and in women at risk of developing contralateral breast cancer. It is also effective as an antineoplastic agent.

An outbred strain of rats developed in 1915 by crossing several Wistar Institute white females with a wild gray male. Inbred strains have been derived from this original outbred strain, including Long-Evans cinnamon rats (RATS, INBRED LEC) and Otsuka-Long-Evans-Tokushima Fatty rats (RATS, INBRED OLETF), which are models for Wilson's disease and non-insulin dependent diabetes mellitus, respectively.

A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.
