Effects of a high corn oil and a high olive oil diet on the histopathologic characteristics of rat dimethylbenz(alpha)anthracene-induced mammary adenocarcinomas were investigated in comparison with those of a control low-fat diet. Two experimental series (A and B) studied the influence of a high
The modulating effect of dietary enrichment in mistol seed oil (MO) containing 25% of alpha-linolenic acid (ALA), evening primrose oil (EPO) enriched in gamma-linolenic acid (GLA) and corn oil (CO) as sources of omega-6 and omega-9 fatty acids on the growth parameters of one transplantable mammary
The activity and subcellular distribution of Protein Kinase C (PKC) was determined in the colons of Sprague-Dawley rats that were fed either a low fat rat chow or rat chow supplemented with 17% corn oil (40% ingested calories as fat). Rats given the high fat diets were either given no carcinogen or
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
Transplantable mammary adenocarcinomas and livers of C3H mice fed a stock diet or a linoleate rich diet (15% corn oil) contain similar amounts of oleate (ca 3 mg/gm tissue). On feeding either a high carbohydrate, fat free or a high carbohydrate, saturated fat-containing (15% hydrogenated coconut or
Induction of apoptosis is an approach to suppress carcinogenesis. The effects of a 12-week treatment of female Sprague-Dawley rats with indole-3-carbinol (I3C), beta-naphthoflavone or vehicle (40% ethanol in corn oil), by oral gavages starting 3 weeks after initiation of mammary tumorigenesis with
The effects of dietary fat concentration (5 vs. 20% corn oil, 0.5 vs. 20% corn oil and fat-free vs. 20% corn oil) on the growth of the Dunning R3327-H (hormone-sensitive, well-differentiated, slow-growing) and R3327-150 (hormone-insensitive, anaplastic, rapidly growing) transplantable prostate tumor
The comparative effects of high-fat diets (20%, w/w) on eicosanoid synthesis during mammary tumor promotion in 7,12-dimethylbenz(a)anthracene (DMBA)-induced rats were studied using diets containing 20% primrose oil (PO), 20% menhaden oil (MO) or 20% corn oil (CO). Sprague-Dawley rats fed the PO or
In this study we have investigated the influence of dietary mono- and polyunsaturated lipids on 7,12-dimethylbenz(alpha)anthracene (DMBA)-induced mammary tumorigenesis, and the modulation of expression of c-erbB1/EGFR and c-erbB2/neu as a mechanism of this influence. Two series of Sprague-Dawley
Three-month-old C3H female mice were given injections of 5-mg pieces of mammary adenocarcinoma and were then fed diets that either were fat free or contained saturated fat (15% hydrogenated cottonseed oil) or linoleate (1-15% corn oil). After 6 weeks, the tumors in mice fed the linoleate diet
The growth of mammary adenocarcinomas in BALB/c mice fed a diet containing 10% corn oil (CO), which has about 60% of its fatty acids as linoleate, was significantly greater than that for tumors in mice fed diets containing either 10% hydrogenated cottonseed oil (HCTO), which has no linoleate, or 10%
A reduction in the size of transplantable mammary adenocarcinoma IX was achieved when female BALB/c mice were fed isocaloric 10% fat diets containing either hydrogenated cottonseed oil (HCTO) or menhaden oil (MO) as opposed to those mice fed corn oil (CO). Indeed, CO increased the size of the
The growth rates of 2 spontaneously developed mammary adenocarcinomas, one in a female C3H mouse and the other in a female BALB/c mouse, were determined after transplantation into isologous female mice fed a specific diet to which various edible fats or pure fatty acids were added. The 18-carbon
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
This report describes exocrine pancreatic insufficiency in a yellow-naped Amazon (Amazona ochrocephala) with complete effacement of the pancreas by a pancreatic adenocarcinoma. The bird presented with a 3-month history of weight loss and voluminous, foul-smelling droppings. Clinically, routine
