lncRNAs expression in the liver of large yellow croaker fed with fish oil, soybean oil, olive oil, and palm oil diets

Project description:To investigate the role of lncRNAs on lipid metabolism, we did RNAseq to find the difference among large yellow croaker fed with fish oil (FO), soybean oil (SO), olive oil (OO), and palm oil (PO) diets

Ozone-Induced Vascular Contractility and Pulmonary Injury are Differentially Impacted by Diets Enriched with Coconut Oil, Fish Oil, and Olive Oil

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.

Gene expression profiles of oil palm leaves from different oil yields and genetic population: Transcriptomic dataset

Project description:Oil palm (Elaeis guineensis Jacq.) is one of the most important oil-producing crops in the world. However, the demand for oil from this crop will increase in the future. A comparative gene expression profile of the oil palm leaves was needed in order to understand the key factors that influence the oil production. Here, we reported an RNA-seq dataset from three different oil yields and three different genetic populations of oil palm. All raw sequencing reads were obtained from an Illumina NextSeq 500 platform. We also provide a list of the genes and their expression levels resulting from the RNA-sequencing. This transcriptomic dataset will provide a valuable resource for increasing oil yield.

Differential effects of krill oil and fish oil on the hepatic transcriptome in mice

Project description:Dietary supplementation with ω-3 polyunsaturated fatty acids (ω-3 PUFAs), specifically the fatty acids docosahexaenoic acid (DHA; 22:6 ω-3) and eicosapentaenoic acid (EPA; 20:5 ω-3), is known to have beneficial health effects including improvements in glucose and lipid homeostasis and modulation of inflammation. To evaluate the efficacy of two different sources of ω-3 PUFAs, we performed gene expression profiling in the liver of mice fed diets supplemented with either fish oil or krill oil. We found that ω-3 PUFA supplements derived from a phospholipid krill fraction (krill oil) downregulated the activity of pathways involved in hepatic glucose production as well as lipid and cholesterol synthesis. The data also suggested that krill oil-supplementation increases the activity of the mitochondrial respiratory chain. Surprisingly, an equimolar dose of EPA and DHA derived from fish oil modulated fewer pathways than a krill oil-supplemented diet and did not modulate key metabolic pathways regulated by krill oil, including glucose metabolism, lipid metabolism and the mitochondrial respiratory chain. Moreover, fish oil upregulated the cholesterol synthesis pathway, which was the opposite effect of krill supplementation. Neither diet elicited changes in plasma levels of lipids, glucose or insulin, probably because the mice used in this study were young and were fed a low fat diet. Further studies of krill oil supplementation using animal models of metabolic disorders and/or diets with a higher level of fat may be required to observe these effects.

Gene expression profile of PBMCs after intake of fish oil for seven weeks compared to high oleic sunflower oil

Project description:Fish oil supplementation has been shown to alter gene expression of mononuclear cells both in vitro and in vivo. However, little is known about the total transcriptomic profile in healthy subjects after intake of fish oil compared to a control group. The objective was to examine the gene expression profile in peripheral blood mononuclear cells (PBMCs) in healthy subjects after intake of fish oil for seven weeks using whole-genome transcriptomic analysis. In a double-blinded randomized controlled study, healthy subjects received capsules containing either 8 g/d of fish oil (1.6 g/d EPA+DHA) (n=17) or 8 g/d of high oleic sunflower oil (n=19) for seven weeks. The results provide important information on how fish oil may modulate basic cellular processes involved in normal cell function and lymphocyte activation such as ER stress, cell cycle and apoptosis.

Human in vivo nutrigenomic effect of olive oil

Project description:Olive oil is protective against risk factors for cardiovascular and cancer diseases. A nutrigenomic approach was performed to assess whether olive oil, the main fat of the Mediterranean diet modifies the gene expression in human peripheral blood mononuclear cells. Six healthy male volunteers ingested, at fasting state, 50 ml of olive oil, and continued with the same olive oil as a source of raw fat (25ml/day) during 3 weeks. Prior to intervention a 1-week washout period with sunflower oil as the only source of fat was followed. During the 3 days before, and on the intervention day, a very low phenolic compound diet was followed. At baseline (0h), at post ingestion (6h), and at fasting state after 3 weeks of sustained consumption of olive oil total RNA was isolated from PBMC. Gene expression was evaluated by microarray and verified by qRT-PCR. Keywords: Olive oil, gene expression, single dose, sustained consumption
