BACKGROUND
Mechanistic data suggest that different types of fatty acids play a role in carcinogenesis and that antioxidants may modulate this relationship but epidemiologic evidence is lacking. Our aim was to investigate the association between plasma saturated, monounsaturated and polyunsaturated

Breast cancer (BC) is the most common cancer among women worldwide. Dietary fatty acids, especially n-3 polyunsaturated fatty acids (PUFA), are believed to play a role in reducing BC risk. Evidence has shown that fish consumption or intake of long-chain n-3 PUFA, such as eicosapentaenoic acid (EPA)
Polyunsaturated fatty acids modulate the delivery of platelet microvesicle-derived microRNAs into human breast cancer cell lines.

Breast cancer is one of the most frequent and malignant types of cancer in women, with an increasing morbidity and mortality rate; in particular, treatment of triple negative breast cancer remains a challenge, since the efforts made with targeted therapies were ineffective. Among surrounding cells

Animal studies suggest that dietary polyunsaturated fatty acids (PUFAs) of the n-6 class, found in corn and safflower oils, may be precursors of intermediates involved in the development of mammary tumors, whereas long-chain (LC) n-3 PUFAs, found in fish oil, can inhibit these effects. This
The janus face of lipids in human breast cancer: how polyunsaturated Fatty acids affect tumor cell hallmarks.

For several years, lipids and especially n - 3 and n - 6 polyunsaturated fatty acids (PUFAs) receive much attention in human health. Epidemiological studies tend to correlate a PUFA-rich diet with a reduced incidence of cancer, including breast cancer. However, the molecular and cellular mechanisms
Polyunsaturated fatty acids in serum phospholipids and risk of breast cancer: a case-control study from the Janus serum bank in Norway.

We have tested the hypothesis that specific polyunsaturated fatty acids (PUFA) of the n-3 and n-6 families, as measured in serum phospholipids, are negatively associated with the risk of breast cancer. The study is based on serum samples from women who have donated blood to the Janus serum bank at
Omega-3 Polyunsaturated Fatty Acids Time-Dependently Reduce Cell Viability and Oncogenic MicroRNA-21 Expression in Estrogen Receptor-Positive Breast Cancer Cells (MCF-7).

The omega-3 polyunsaturated fatty acid (n-3 PUFA), α-linolenic acid (ALA), and its metabolites, eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), independently reduce the growth of breast cancer cells in vitro, but the mechanisms, which may involve microRNA (miRNA), are still unclear. The
Effect of n-3 and n-6 polyunsaturated fatty acids on lipid metabolic genes and estrogen receptor expression in MCF-7 breast cancer cells.

BACKGROUND
To investigate the effect of different ratios of n-6/n-3 polyunsaturated fatty acids (PUFAs) on the expression of lipid metabolic genes and estrogen receptor (ER).
METHODS
This study took place in the Department of Surgery, Women's Hospital, School of Medicine, Zhejiang University,

Higher intake of ω-3 relative to ω-6 polyunsaturated fatty acids (PUFAs) may reduce breast carcinogenesis via different metabolic pathways. The PUFA-breast cancer association remains inconclusive, thus, we hypothesized that interactions between the ratio of dietary ω-3:ω-6 intake and polymorphisms
Omega-3 polyunsaturated fatty acids regulate syndecan-1 expression in human breast cancer cells.

Human epidemiologic studies and animal model studies support a role for n-3 polyunsaturated fatty acids (n-3 PUFA) in prevention or inhibition of breast cancer. However, mechanisms for this protection remain unclear. Syndecan-1 is a heparan sulfate proteoglycan, expressed on the surface of mammary

OBJECTIVE
The aim of this study was to investigate the association between the content of marine n-3 polyunsaturated fatty acids (PUFA) in adipose tissue, a biomarker for the long-term intake of seafood, and the subsequent development of breast cancer (BC).
METHODS
We designed a case-cohort study

Polyunsaturated fatty acid (PUFA), a key marker in breast cancer, is non-invasively quantifiable using multiple quantum coherence (MQC) magnetic resonance spectroscopy (MRS) at the expense of losing half of the signal. Signal combination for phased array coils provides potential pathways to enhance
Dietary modulation of omega-3/omega-6 polyunsaturated fatty acid ratios in patients with breast cancer.

BACKGROUND
Polyunsaturated fatty acids of the omega-6 (omega-6) class, as found in corn and safflower oils, can act as precursors for intermediates involved in the growth of mammary tumors when fed to animals, whereas polyunsaturated fatty acids of the omega-3 (omega-3) class, as found in fish oil,
HER2 (erbB-2)-targeted effects of the omega-3 polyunsaturated fatty acid, alpha-linolenic acid (ALA; 18:3n-3), in breast cancer cells: the "fat features" of the "Mediterranean diet" as an "anti-HER2 cocktail".

BACKGROUND
Data derived from epidemiological and experimental studies suggest that alphalinolenic acid (ALA; 18:3n-3), the main omega-3 polyunsaturated fatty acid (PUFA) present in the Western diet, may have protective effects in breast cancer risk and metastatic progression. A recent pilot clinical

Overexpression of the tyrosine kinase receptor, ErbB2/HER2/Neu, occurs in 25-30% of invasive breast cancer (BC) with poor patient prognosis. Due to confounding factors, inconsistencies still remain regarding the protective effects of n-3 polyunsaturated fatty acids (PUFAs) on BC. We therefore
