[Conjugated linoleic acid as a potential protective factor in prevention of breast cancer].

Numai utilizatorii înregistrați pot traduce articole

Cancers are the second leading cause of deaths in Poland, among both women and men. Breast cancer is the malignancy most frequently diagnosed in women. In 2008 mammary cancer was diagnosed in up to 14 500 patients. It is also the second most common cause of cancer deaths among women in our country.

Inhibition of stearoyl-CoA desaturase activity by the cis-9,trans-11 isomer and the trans-10,cis-12 isomer of conjugated linoleic acid in MDA-MB-231 and MCF-7 human breast cancer cells.

Conjugated linoleic acid (CLA) is a collective term for a group of positional and geometric conjugated dienoic isomers of linoleic acid. CLA has been shown to have strong inhibitory effects on mammary carcinogenesis both in vitro and in vivo. In this study, we investigated the regulation of human

Chemometric analysis of the interactions among different parameters describing health conditions, breast cancer risk and fatty acids profile in serum of rats supplemented with conjugated linoleic acids.

We investigated how different doses of conjugated linoleic acids applied for various periods of time influence breast cancer risk and fatty acids profile in serum of rats treated or not with 7,12-dimethylbenz[a]anthracene (DMBA). We also search for interactions among parameters describing health

Conjugated linoleic acid (CLA) inhibits expression of the Spot 14 (THRSP) and fatty acid synthase genes and impairs the growth of human breast cancer and liposarcoma cells.

Spot 14 (THRSP, S14) is a nuclear protein involved in the regulation of genes required for fatty acid synthesis in normal and malignant mammary epithelial and adipose cells. Harvatine and Bauman (1) reported that conjugated linoleic acid (CLA) inhibits S14 gene expression in bovine mammary and mouse

Enhanced anticancer effect of conjugated linoleic acid by conjugation with Pluronic F127 on MCF-7 breast cancer cells.

This study is designed to evaluate whether conjugated linoleic acid-coupled Pluronic F127 (Plu-CLA) enhances anticancer efficacy in MCF-7 breast cancer cells when compared to conjugated linoleic acid (CLA) itself. CLA was simply coupled to Pluronic F127 through ester linkage between carboxyl group

Conjugated linoleic acid induces apoptosis in MDA-MB-231 breast cancer cells through ERK/MAPK signalling and mitochondrial pathway.

We investigated the molecular mechanisms involved in the anti-proliferative activity exerted by conjugated linoleic acid (CLA) on the estrogen unresponsive MDA-MB-231 human breast cancer cell line. The effects on cell proliferation, cell cycle progression and induction of apoptosis were examined.

A mixture of trans, trans conjugated linoleic acid induces apoptosis in MCF-7 human breast cancer cells with reciprocal expression of Bax and Bcl-2.

The growth inhibitory effect of a mixture of trans, trans conjugated linoleic acid isomers (t, t CLA) was investigated in a human breast cancer cell line, MCF-7, with references to c9, t11 CLA, t10, c12 CLA, and linoleic acid. The t, t CLA treatment effectively induced a cytotoxic effect in a

Attenuation of breast tumor cell growth by conjugated linoleic acid via inhibition of 5-lipoxygenase activating protein.

Numai utilizatorii înregistrați pot traduce articole

Conjugated linoleic acid (CLA) consists of a group of linoleic acid geometric isomers that have been shown to reduce tumor growth and metastasis in animal models of breast, prostate and colon cancer. To delineate a possible mechanism of action for CLA, we have recently shown that the 5-lipoxygenase

Proliferative responses of normal human mammary and MCF-7 breast cancer cells to linoleic acid, conjugated linoleic acid and eicosanoid synthesis inhibitors in culture.

Numai utilizatorii înregistrați pot traduce articole

Potential mechanisms for the stimulation or inhibition of cell growth by linoleic acid (LA) and conjugated linoleic acid (CLA) were investigated by using eicosanoid synthesis inhibitors. Normal human mammary epithelial cells (HMEC) and MCF-7 breast cancer cells were incubated in serum-free medium

The anti-proliferative and pro-apoptotic effects of the trans9, trans11 conjugated linoleic acid isomer on MCF-7 breast cancer cells are associated with LXR activation.

Conjugated linoleic acids (CLA), naturally found in dairy products and ruminant meat, are positional and geometric isomers (trans: t or cis: c) of linoleic acid, and have been widely reported to possess anti-tumoral activity against breast cancer both in vitro and in vivo. CLA isomer t9,t11 was

Modulation of MCF-7 breast cancer cell signal transduction by linoleic acid and conjugated linoleic acid in culture.

Numai utilizatorii înregistrați pot traduce articole

The effects of modifying membrane fatty acid composition on cell growth, phospholipase C (PLC) and protein kinase C (PKC) activities, and prostaglandin E2 (PGE2) secretion were investigated. Hormone responsive MCF-7 human breast cancer cells were incubated in a serum-free medium containing epidermal

Conjugated linoleic acid attenuates cyclooxygenase-2 transcriptional activity via an anti-AP-1 mechanism in MCF-7 breast cancer cells.

Numai utilizatorii înregistrați pot traduce articole

Overexpression of cyclooxygenase-2 (COX-2) is regarded as a causative factor in the onset of tumorigenesis of the breast. In this study, we investigated the effects of conjugated linoleic acid (CLA) on COX-2 transcription in MCF-7 breast cancer cells. Results of transient transfection studies

Conjugated linoleic acid content in breast adipose tissue of breast cancer patients and the risk of metastasis.

Numai utilizatorii înregistrați pot traduce articole

The association between the level of conjugated linoleic acid (CLA) in breast adipose tissue at the time of diagnosis and the subsequent development of metastasis was examined in a cohort of 209 patients presenting with an initially localized breast cancer. CLA level in breast adipose tissue was

The dietary c9,t11-conjugated linoleic acid enriched from butter reduces breast cancer progression in vivo.

Numai utilizatorii înregistrați pot traduce articole

The c9,t11-conjugated linoleic acid (CLA), which is the minor polyunsaturated fatty acid (PUFA) naturally present in butter, has gained attention due to its important preventive effect against breast cancer in vitro. In this paper, the enrichment of c9,t11-CLA from butter was optimized and the

Effect of conjugated linoleic acid isomers on growth factor-induced proliferation of human breast cancer cells.

Numai utilizatorii înregistrați pot traduce articole

We evaluated the effect of conjugated linoleic acid (CLA) isomers on the growth factor-induced proliferation of human breast cancer MCF-7 cells. When MCF-7 cells were cultured in RPMI 1640 medium supplemented with 1% fetal bovine serum (FBS), CLA inhibited the proliferation and notably cis9, trans11
