(C57BL/6 x DBA/2)F1 mice were fed antioxidant-matched fish oil (FO) or corn oil (CO) diets for weeks, were challenged with B16.F10 melanoma cells, and lung metastases were enumerated 17 days later. Mice fed FO had fewer lung tumors than mice fed CO. This dietary effect persisted in mice injected
Corn pectic polysaccharide (COPP) inhibited galectin-3 mediated hemagglutination at Minimum Inhibitory Concentration (MIC) of 4.08 μg/mL as opposed to citrus pectin (25 μg/mL), a well known galectin-3 inhibitor and lactose (4.16 μg/mL)--sugar specific to galectin-3. COPP effectively (72%) inhibited
The effect of a high-fat (HF) diet (23% corn oil) on the growth and metastasis of the 13762 mammary tumor in Fischer 344 retired breeder (RB) and young virgin (YV) female rats was studied. The RB (10-12 mo old) and YV (8 wk old) rats were fed the HF or low-fat (LF) diet (5% corn oil) prior to and
The purpose of the study was to determine the effect of three different levels of dietary linoleic acid (LA) intake on the growth of MDA-MB-435 human breast cancer cells in the mammary fat pads of nude mice, and their metastasis to the lungs. These diets were isocaloric, and contained different
The amount and type of dietary lipid can significantly influence spontaneous tumor development and tumor progression. To determine the effect of fish oil (rich in omega-3 polyunsaturated fatty acids) and corn oil (rich in omega-6 polyunsaturated fatty acids) on primary tumor growth, metastasis and
Experiments were performed to investigate whether the type of dietary fat might affect metastasis from the 13,762 mammary tumor. Female Fischer 344 retired breeder rats were placed into one of five dietary groups: 23% (wt/wt) and 5% (wt/wt) corn oil (HFCO, LFCO), 20% (wt/wt) and 5% (wt/wt) olive oil
We investigated the effect of dietary supplementation with selenium on spontaneous metastasis of Lewis lung carcinoma in mice fed a high-fat diet. Mice were fed a low-fat diet or that diet modified with 45% of calories from corn oil and supplemented with 0 or 2.5mg selenium/4029 kcal as
BACKGROUND
Diets rich in omega-6 polyunsaturated fatty acids (e.g., corn oil and other fats containing linoleic acid) stimulate the growth and metastasis of human breast cancer cells in athymic nude mice. On the other hand, diets containing fish oil, which is rich in omega-3 fatty acids (e.g.,
Animal studies consistently show that dietary conjugated linoleic acid (CLA) reduces mammary tumorigenesis including metastasis. Relatively low concentrations of CLA are required for those effects, and a threshold level exists above which there is no added reduction. We reasoned that the
The purpose of Study 1 was to examine the effect of dietary soy on the progression of MDA-MB-435 human breast cancer cell solid tumors in nude mice. When toasted soy chips were fed at levels of 5%, 10%, or 20% (wt/wt) in a high-fat, linoleic acid-rich diet for 12 weeks, there was a trend for larger
The effect of feeding mice diets high in beef tallow (high in saturated fat) or corn oil (high in polyunsaturated fat) on the production of lung metastases by the Lewis lung carcinoma and the BALB/c mammary tumor was determined. Diets were fed ad libitum, and the mice fed the high-fat (24.6%) diets
Two contradictory actions have been ascribed to thalidomide relative to tumor metastasis: immunosuppression and anti-angiogenesis. The latter effect was determined with basic fibroblast growth factor in a rabbit cornea micropocket assay system. The prostate adenocarcinoma (PA-III) transplanted tumor
Results from epidemiological studies have generally indicated an association of dietary saturated animal fats with human breast cancer risk. Some studies, however, have suggested a similar association for some polyunsaturated vegetable fats shown to promote both rodent mammary carcinogenesis and
The effect of changing the amount of polyunsaturated fat in the diet of aged female Fischer 344 rats at the time of tumor implant on metastasis from the 13762 transplantable mammary tumor was studied. Three experiments were performed. (a) Retired breeders, maintained on standard commercial chows
The effects of a fish oil diet on the myelopoietic and immunological parameters of normal mice and of mice bearing metastatic Lewis lung carcinoma (LLC-C3) tumors were compared to the effects of a corn oil or a mixed-fat rodent chow diet. This was studied soon after tumor appearance, on Day 17, when
