eicosapentaenoic acid/breast neoplasms

Dietary supplementation with 4% eicosapentaenoic acid (EPA), a long-chain polyunsaturated fatty acid, suppressed the development of lung metastases in nude mice from MDA-MB-435 human breast cancer cell mammary fat pad solid tumors. Zymography of primary tumor homogenates showed that this inhibition

Numerous studies have shown dietary fatty acids to influence the progression of several types of cancers. The purpose of the present investigation was to examine the influence of various types of fatty acids, including omega-3 fatty acids and a new class of hypolipidemic peroxisome proliferating

Postmenopausal breast cancer survivors are living longer; however, a common class of drugs, aromatase inhibitors (AI), depletes estrogen levels, promotes bone loss, and heightens fracture risk. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) may offset AI effects to bone because of the

To gain some insight into the mechanisms involved in the opposing effects of linoleic acid (LA) and eicosapentaenoic acid (EPA) on the growth and invasiveness of MDA-MB-435 human breast cancer cells, the dynamics of the uptake by cells and the incorporation of [14C]LA and [14C]EPA into major lipid

Cancer cell adhesion to the subendothelial extracellular matrix (ECM) is an important step in metastasis formation. The effect of epidermal growth factor (EGF) and eicosapentaenoic acid (EPA) on adhesion of the highly metastatic MDA-MB-231 human breast cancer cell line to ECM components was examined

The effects of eicosapentaenoic acid (EPA) and an angiogenesis inhibitor (TNP-470) on the suppression of breast cancer cell growth were examined in five human breast cancer cell lines (MDA-MB-231, T-47D, MCF-7, KPL-1, and MKL-F). In all five cell lines, EPA and TNP-470 alone both showed tumor growth

OBJECTIVE To determine the in vitro effects of simultaneously administered LY29400, PD98059, tamoxifen and eicosapentaenoic acid (EPA) on breast cancer cells, and determine their transcutaneous delivery. METHODS Growth assays were performed on MCF-7 cells challenged with IC(50) and permeated

BACKGROUND Tamoxifen resistance is the underlying cause of treatment failure in a significant number of patients with breast cancer. Activation of Akt, a downstream mediator in the phosphatidylinositol 3-kinase (PI3K) signaling pathway has been implicated as one of the mechanisms involved in

Triple-negative breast cancer (TNBC), the most aggressive breast cancer subtype, currently lacks effective targeted therapy options. Eicosapentaenoic acid (EPA), an omega-3 fatty acid and constituent of fish oil, is a common supplement with anti-inflammatory properties. Although it is not a

Epidemiological studies have associated high fish oil consumption with decreased risk of breast cancer (BC). n-3 long chain polyunsaturated fatty acids (n-3 LCPUFA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) found in fish and fish oils exert anti-cancer effects. However, few studies

Obesity is a major risk factor for breast cancer (BC). Obesity-related metabolic alterations such as inflammation and overactivation of the adipose renin-angiotensin system (RAS) may contribute to the progression of BC. Clinically used antihypertensive drugs such as angiotensin-converting enzyme

The type and content of dietary PUFAs have profound influences on the growth rate of transplantable human breast cancers in immunodeficient rodents. Diets enriched in linoleic acid (LA), an (n-6) fatty acid, stimulate tumor growth, whereas dietary fats containing (n-3) fatty acids slow such growth.

Breast cancer is the leading cause of death in women among all cancer types. Obesity is one of the factors that promote progression of breast cancer, especially in post-menopausal women. Increasingly, adipose tissue is recognized for its active role in the tumor microenvironment. We hypothesized

Genistein, a prominent isoflavone in soy products, produced dose- and time-dependent in vitro growth inhibition at high concentrations (at least 185 microM) with an IC50 of 7.0-274.2 microM after 72 h incubation in four breast cancer cell lines (DD-762, Sm-MT, MCF-7 and MDA-MB-231) and one breast
