Epidemiological and animal studies suggest an association between dietary fatty acids and an increase risk of developing breast cancer. Obesity, which is characterized by hyperlipidemia and an elevation of circulating free fatty acids (FFAs), is also associated with enhanced cancer risk. In breast
GPR40 and GPR120 are G-protein-coupled receptors that can be activated by medium- and long-chain fatty acids. GPR40 is expressed in several breast cancer cell lines and its stimulation with oleic acid (OA) induces cell proliferation. However, the signal transduction pathways activated by OA have not
Epidemiological studies and animal models suggest an association between high levels of dietary fat intake and an increased risk of breast cancer. In breast cancer cells, the free fatty acid oleic acid (OLA) induces proliferation, migration, invasion and an increase of MMP-9 secretion. However, the
An association between dietary fatty, obesity and an increased risk of developing breast cancer has been suggested. In breast cancer cells, free fatty acids (FFAs) mediate biological effects including cell proliferation and ERK1/2 activation. However, the contribution of FFAs to tumor progression
A case control study has been conducted to determine the value of stearic/oleic acid ratios in the erythrocyte membranes of women at the time of presentation with breast cancer. No difference was found between the stearic/oleic acid ratio of cases and that of controls with benign breast condition or
The mechanisms underlying breast cancer progression of ductal carcinoma in situ (DCIS) associated with fatty acids are largely unknown. In the present study, we compared the action of oleic acid (OA) on two human DCIS cell lines, MCF10DCIS.COM (ER/PR/HER2-negative) and SUM225 (HER2 overexpressed).
Anacardic acid is a dietary and medicinal phytochemical that inhibits breast cancer cell proliferation and uncouples oxidative phosphorylation (OXPHOS) in isolated rat liver mitochondria. Since mitochondrial-targeted anticancer therapy (mitocans) may be useful in breast cancer, we examined the
Free fatty acids (FFAs) are an energy source, and induce activation of signal transduction pathways that mediate several biological processes. In breast cancer cells, oleic acid (OA) induces proliferation, matrix metalloproteinase-9 (MMP-9) secretion, migration and invasion. However, the signal
Gastric cancer and breast cancer have a clear tendency toward metastasis and invasion to the microenvironment predominantly composed of adipocytes. Oleic acid is an abundant monounsaturated fatty acid that releases from adipocytes and impinges on different energy metabolism responses. The effect and
BACKGROUND
The relationship between the intake of olive oil, the richest dietary source of the monounsaturated fatty acid oleic acid (OA; 18:1n-9), and breast cancer risk and progression has become a controversial issue. Moreover, it has been suggested that the protective effects of olive oil
The influence of cell membrane fluidity on cancer progression has been established in different solid tumors. We previously reported that "cancer-associated fibroblasts" (CAFs) induced epithelial-mesenchymal transition and increased cell membrane fluidity and migration in poorly (MCF-7) and highly
It has been suggested that dietary interventions may improve the effectiveness of cancer chemotherapy. We have examined the combined in vitro cytotoxicity of paclitaxel and the fatty acids gamma-linolenic acid (GLA, 18:3n-6) and oleic acid (OA, 18:1n-9) in human breast carcinoma MDA-MB-231 cells.
BACKGROUND
Consumption of a high-fat diet has been associated with poor survival in breast cancer patients. However, studies examining this association are limited and have not used adjustment of energy in their estimates.
OBJECTIVE
The effect of usual diet before diagnosis of breast cancer on the
OBJECTIVE
Diet has been postulated to influence breast cancer prognosis; however, existing evidence is weak and inconsistent. Previous studies have sought evidence of a linear relationship between diet and breast cancer outcomes. Because of a U-shaped association of body mass index (BMI) with
A case-control study of breast cancer was conducted in Hawaii with Japanese and Caucasian women between ages 45 and 74. Each case was matched to one hospital and one neighborhood control. In all, 183 sets of Japanese and 161 sets of Caucasian subjects were interviewed. No statistically significant
