Project description:Soybean and fish contains various active components that were reported to prevent cardiovasucular diseases. Epidemiological studies indicated that Asian eating patterns, consisting of daily seafood and/or soy consumption, confer protection against cardiovascular diseases. In this context, we expected that simultaneous intake of soybean and fish may be greatly beneficial in a manner different from the ingestion of the individual food. To understand the detailed mechanism for modulating the lipid metabolism by co-ingestion of a soy food (tofu) and fish oil, we investigated the global changes in hepatic mRNA expression in rats by using a microarray analysis. Generally, ingestion of tofu contributed to prevent the mRNA expressions involved in hepatic lipogenesis, whereas fish oil facilitated the mRNA expressions related to the degradation of hepatic fatty acids. In terms of mRNA expression, the interaction of two dietary factors was limited. The expression data was normalized and summarized by using SuperNORM data service (Skylight Biotech Inc.). Significance of expressional change among groups was tested by 2-way ANOVA on the normalized CEL data, which was deposited in a tab-separated ASCII text format. Principal components were identified on the summarized gene data. Rats were divided into four groups each with similar average body weights and assigned experimental diets for 21 days as follows: casein and soybean oil diet (CS); casein and fish oil diet (CF); tofu and soybean oil diet (TS); tofu and fish oil diet (TF). Total protein and fat content of each diet was 200 and 150 g/kg, respectively. Soybean oil diets (CS and TS) contain 150 g/kg diet of soybean-derived fat (i.e. soybean oil and freeze-dried tofu), and 50 g/kg of fish oil was replaced with the same amount of soybean-derived fat for fish oil diets (CF and TF). Animals were allowed free access to food and water.

Project description:Fish oil, olive oil, and coconut oil dietary supplementation have several cardioprotective benefits, but it is not established if they can protect against air pollution-induced adverse effects. We hypothesized that these dietary supplements would attenuate ozone-induced systemic and pulmonary effects. Male Wistar Kyoto rats were fed either a normal diet, or a diet enriched with fish, olive, or coconut oil starting at 4 weeks of age for 8 weeks. Animals were then exposed to air or ozone (0.8 ppm), 4h/day for 2 consecutive days. The fish oil diet completely abolished phenylephrine-induced vasoconstriction that was increased following ozone exposure in the animals fed all other diets. Only the fish oil diet increased baseline levels of bronchoalveolar lavage fluid (BALF) markers of lung injury and inflammation. Ozone-induced pulmonary injury/inflammation were comparable in rats on normal, coconut oil, and olive oil diets with altered expression of markers in animals fed the fish oil diet. Fish oil, regardless of exposure, led to enlarged, foamy macrophages in the BALF that coincided with decreased mRNA expression of cholesterol transporters, cholesterol receptors, and nuclear receptors in the lung. Serum miRNA profile was assessed using small RNA-sequencing in normal and fish oil groups and demonstrated marked depletion of a variety of miRNAs, several of which were of splenic origin. No ozone-specific changes were noted. Collectively, these data indicate that while fish oil offered protection from ozone-induced aortic vasoconstriction, it increased pulmonary injury/inflammation and impaired lipid transport mechanisms resulting in foamy macrophage accumulation, demonstrating the need to be cognizant of potential off-target pulmonary effects that might offset the overall benefit of this vasoprotective dietary supplement.

Project description:PURPOSE: Previous mouse studies using corn oil (ω-6) as the dietary fat source suggest that decreasing dietary fat content can slow prostate cancer (PCa) growth. However, other studies, in which the diet was composed around saturated fat, showed no difference in outcomes between high-fat and low-fat diets. The relative effects of other fats, such as fish oil and olive oil, also remain unexplored. To our knowledge, no trial has yet compared the effect of various fats on prostate cancer progression. Therefore, we sought to systematically study the effect of fish oil, olive oil, corn oil, and saturated fat on prostate cancer progression. METHODS: A total of 96 male SCID mice were injected with LAPC-4 human PCa cells. Two weeks following injection, mice were singly-housed and randomized to either a fish oil, olive oil, corn oil, or saturated fat based diet. Animals were euthanized when tumors reached 1,000 mm3. Serum was collected at sacrifice and assayed for PSA, insulin, IGF-1, IGFBP-3, and PGE-2 levels. Tumors were also assayed for PGE-2, and COX-2 levels, and gene array analysis was performed. RESULTS: Mice weights and tumor volumes were equivalent across groups at randomization. Overall, fish-oil consumption was associated with improved survival, relative to all other dietary groups (Log-rank, all p<0.05). We did not detect any significant difference in serum PSA, insulin, IGF-1, IGFBP-3, and PGE-2 levels. Glucose at the time of sacrifice was statistically different between groups, with the fish-oil fed mice having the highest levels of serum glucose (Kruskal-Wallis, p=0.03). CONCLUSIONS: In this prostate cancer xenograft model, we found that consuming a diet in which fish-oil was the only fat source slowed tumor growth in improved survival, compared to mice consuming diets composed of olive oil, corn oil, or saturated fat sources. These results suggest that type of dietary fat consumed may be as important as amount of dietary fat consumed in the setting of prostate cancer.

Project description:Since the liver is the central organ of metabolism, changes in diet have a great impact on this organ and overall on health with aging. It is well known that dietary fat source strongly influences many parameters of the hepatic mitochondria. These changes includes modification of lipid composition of mitochondrial membrane, affecting the mtETC functions, oxidative stress and mtDNA alterations. We used microarrays to detail the changes in gene expression provides by feeding lifelong on different dietary fat sources, and identified distinct classes of up and down-regulated genes during aging under different dietary conditions. Rats were fed lifelong on a normolipidic diet (4% w/w) with virgin olive, sunflower or fish oil as dietary fat source. At 6 and 24 months, animals were killed and liver were removed for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain changes in gene expression due to both aging and dietary conditions. There were 6 experimental groups (virgin olive oil at 6 months, sunflower oil at 6 months, fish oil at 6 months, virgin olive oil at 24 months, sunflower oil at 24 months and fish oil at 24 months. 3 animals were studied of each experimental group, so a total of 18 samples were analyzed.

Project description:There is an increasing drive to replace fish oil (FO) in finfish aquaculture diets with vegetable oils (VO), driven by the short supply of FO derived from wild fish stocks. Little is known of the consequences for fish health after such substitution. The effect of dietary VO on hepatic gene expression was determined in Atlantic salmon (Salmo salar) byg a cDNA microarray analysis. Post-smolt farmed salmon were reared for x weeks on diets where the FO component of the feed was replaced with one of three different VOs - rapeseed (RO), soybean (SO) or linseed (LO). RNA from five fish fed on each diet was extracted. A total of 20 cDNA microarray hybridisations - TRAITS / SGP Atlantic salmon 17k feature cDNA microarray - were performed - 4 diets (three VO + FO control) x 5 individuals - using a common pooled reference control design. Data were obtained from 19 of the 20 hybridisations.
