Dietary lipids have a role in the aetiology of breast cancer. We have reported earlier that a high corn oil diet downregulates H19 and vitamin D3 upregulated protein 1 (VDUP1) messenger RNA (mRNA) expression in rat dimethylbenz (alpha) anthracene-induced mammary adenocarcinomas in comparison with

Our earlier work has shown a selective promotional effect on the genesis of mammary carcinomas bearing a wild-type, but not mutant, Ha-ras codon 12 in a 1-methyl-1-nitrosourea (MNU)-induced carcinogenesis model by high-fat diets (Nutr Cancer 23, 283-290, 1995). To test the hypothesis that activation

Breast cancer is the most common malignancy in women worldwide, and dietary lipids are important environmental factors influencing its etiology. In this work we present data in relation to the transcriptional effects of two high-fat diets, one high in corn oil (HCO) and one high in extra-virgin

Treatment of human endothelial cells with cytokines such as tumour necrosis factor-alpha (TNF) or E. coli lipopolysaccharide (LPS) induces the expression of several adhesion molecules and enhances leukocyte adhesion to endothelial cell surface. Interfering with this leukocyte adhesion or adhesion

Fish or vegetable oils were fed during the promotion stage of a mouse skin carcinogenesis model in order to investigate the effects of dietary fat on tumor development. Two weeks after initiation with 10 nmol dimethylbenz[a]anthracene, SENCAR mice were divided into five groups and maintained on one

Hepatic mitochondrial outer membrane carnitine palmitoyltransferase I (CPT I) and mitochondrial 3-hydroxy-3-methylglutaryl-CoA synthase (HMG-CoA synthase) enzymes play a key role in regulation of fatty acid oxidation and in ketogenic pathways, respectively. Their expression are regulated by fatty

Extra-virgin olive oil (EVOO) has been hypothesized to have chemopreventive effects on breast cancer, unlike high corn oil (HCO) diets that stimulate it. We have investigated mechanisms of these differential modulatory actions on experimental mammary cancer. In 7,12-dimethylbenz(a)anthracene

Experimental evidence highlights the importance of dietetic factors on breast cancer. In this work we aimed to analyze the effects two oils, corn oil (rich in n-6 polyunsaturated fatty acids -PUFA-) and extra virgin olive oil (EVOO), on oxidative stress in an animal model of breast carcinogenesis.

The effects of specific dietary interventions on incidence of carcinogen-induced cancer and on cryptal cell proliferation in areas of the colon located either over aggregates of lymphoid nodules (ALN) or away from ALN was investigated. Groups of dimethylhydrazine (DMH) treated rats or

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

X-Ray microanalysis, performed by both scanning and transmission electron microscopes equipped with energy-dispersive spectrometers (EDS), was used to analyze the element distribution in phloem tumors induced by maize rough dwarf virus (MRDV) in Zea mays L. The content of both Si and Ca was lower in

High extra-virgin olive oil (EVOO) and corn oil diets differentially modulate experimental mammary carcinogenesis. We have investigated their influence on the initiation stage through the modulation of the expression of xenobiotic-metabolizing enzymes (XMEs) in the liver and the mammary gland.

Dose-related effects of long-chain highly unsaturated n-3 fatty acids on the development of N-nitrosomethylurea (NMU)-induced rat mammary tumors were assessed in female F344 rats. Four test groups (36 rats/group) were fed the following high-fat (HF) diets (23% fat, w/w): Group 1, 18% menhaden oil

In chronic carcinogenic bioassays, chemicals being tested with low water solubility have been administered via corn oil gavage. The present study examined the effect of chronic corn oil gavage on hepatic tumor formation in the B6C3F1 male mouse. Mice were initiated with diethylnitrosamine (DENA)

How dietary corn oil is involved in colon carcinogenesis and cancer development is poorly understood. The aim of this study was to investigate whether long-term dietary corn oil promotes colon cancer by inhibiting the tumor suppressor gene p53-mediated mitochondria-dependent apoptosis in
