Project description:To explore the influence of maternal choline intake on placental gene expression, we employed whole genome microarray expression profiling to identify genes that were differentially expressed in placental tissues obtained from women consuming two different doses (480 vs. 930 mg/d) of choline throughout the third trimester of pregnancy. Healthy third trimester (gestational week 26-29) pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6) or 930 (n=6) mg choline/d. Full thickness placental samples were collected at delivery to extract RNA and perform the arrays. Healthy third trimester (gestational week 26-29) pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6) or 930 (n=6) mg choline/d for 12 weeks. Placental samples were obtained at delivery

Project description:The objective of this study was to identify metabolic regulatory mechanisms affected by choline availability in rainbow trout (Oncorhynchus mykiss) broodstock diets associated with increased offspring growth performance. Three customized diets were formulated to have different levels of choline: (a) 0% choline supplementation (Low Choline: 2065 ppm choline), (b) 0.6% choline supplementation (Medium Choline: 5657 ppm choline), and (c) 1.2% choline supplementation (High Choline: 9248 ppm choline). Six all-female rainbow trout families were fed experimental diets beginning 18 months post-hatch until spawning; their offspring were fed a commercial diet. Experimental broodstock diet did not affect overall choline, fatty acid, or amino acid content in the oocytes (p > 0.05), apart from tyrosine (p ≤ 0.05). Offspring body weights from the High and Low Choline diets did not differ from those in the Medium Choline diet (p > 0.05); however, family-by-diet and sire-by-diet interactions on offspring growth were detected (p ≤ 0.05). The High Choline diet did not improve growth performance in the six broodstock families at final harvest (520-days post-hatch, or dph). Numerous genes associated with muscle development and lipid metabolism were identified, including myosin, troponin C, and fatty acid binding proteins, which were associated with key signaling pathways of lipid metabolism, muscle cell development, muscle cell proliferation, and muscle cell differentiation. These findings indicate that supplementing broodstock diets with choline does regulate expression of genes related to growth and nutrient partitioning but does not lead to growth benefits in rainbow trout families selected for disease resistance.

Project description:Previous studies have used this model to show that PC-TP has a protective effect when challenged with a methionine and choline depleted diet, known to induce NAFLD. We performed transcription factor binding experiments and show that PPARs are dysregulated in the contect of PC-TP depletion We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 Mice for WT and KO fed either normal chow or methionine and choline depleted chow.

Project description:Weanling rats fed a choline-deficient diet develop acute renal failure (ARF) after 6-7 days of receiving the experimental diet. Its pathogenesis is controversial. Menhaden oil has a protective effect in this experimental model. The aim of this study is to describe both the genetic profile and its changes when vegetable oils are replaced by menhaden oil. Wistar, weanling rats from the Animal Facility of the Centre of Experimental and Applied Pathology were divided into 4 groups and fed with the following diets: 1- Choline-deficient diet with vegetable oils as lipids (corn and hydrogenated oils); 2- Choline-supplemented diet with vegetable oils as lipids; 3- Choline-deficient diet with menhaden oil as lipid; and 4- Choline supplemented diet with menhaden oil as lipid. Animals were sacrificed after 6 days of receiving the experimental diets. The right kidney was cryopreserved. In this assay biological duplicated samples were used. In order to evaluate changes in gene expression WT Expression Kit (Ambion, USA) over the platform GeneChip® Gene 1.0 ST Rat Genome Array (Affymetrix Inc, USA) was used. Fluorescent distribution in the array was obtained using the language R (www-r-project.org), in house own algorithms and other formsbioconductor tools http://www.bioconductor.org/. We analyzed the differential gene expression, using as cut value p<0.01 with fdr control & |log FC|>1.5, in all groups. Rats fed with diets 2, 3 and 4 have similar genetic profiles. However, the comparison between rats fed with diets 2 and 4 showed 35 genes with diferential expression. As these rats did not have renal necrosis, we can hypothesize that the differential expression is due to the menhaden oil of the diet. In short, the massive analysis of genetic expression allowed to confirm that menhaden oil has a protective effect in this experimental model and to identify 35 genes that could be responsible of that protection. Twenty eight animals were sacrificed after 6 days of receiving the experimental diets. The right kidney was cryopreserved for microarray analysis. Cryopreserved kidney was pulverized under liquid-nitrogen conditions. Total RNA was purified from 30 mg of frozen rat kidney tissue. Each sample represents a pool of 3 animals (except CD+AM SN with 2 animals/pool), to reduce biological variation. In this assay biological duplicated samples were used.

Project description:The present study aimed to examine the effect of high-fat diet prior to pregnancy on the liver of mouse offspring. Female C57BL/6J mice were fed a normal chow (15.2% fat by energy) (CTR and CTR-PP groups) or a high-fat chow (31.2% fat by energy) (HFD and HFD-PP groups) for 3−4 weeks and then mated with male C57BL/6J mice fed normal chow. Some mothers continued on the same diet until pups reached 21 days of age (CTR and HFD), and others were fed the different chows from gestational day 0 (CTR-PP and HFD-PP) to determine the effects of a high-fat diet during the pre-pregnancy period in HFD-PP/CTR and HFD/CTR-PP comparisons. RNA sample was taken from liver of 3-week-old mouse prenatally received high-fat diet prior to pregnancy, during pregnancy and lactation, or through prior to and during pregnancy and lactation, while control RNA was taken from control counterpart prenatally received normal diet alone. Comparisons among groups were made by one-color method with normalized data from Cy3 channels for data analysis.

Project description:The objective of this study is to explore gene expression profiles of liver tissues in response to choline defficient diet by DNA microarray data analysis. Male CD-1mice (5 weeks) were fed either a choline-deficient diet (F2CDD, Oriental Yeast) or F2CDD plus 0.2% choline bitartrate for 3 weeks. Liver tissue from control versus choline-deficient samples were analyzed for gene expression on an Agilent Whole Mouse Genome Microarray.

Project description:To explore the influence of choline intake and pregnancy status on gene expression, we employed whole genome microarray expression profiling to identify genes that were differentially expressed between two choline intake groups and between pregnant and non-pregnant women. Healthy third trimester (gestational week 26-29) pregnant women and non-pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6 pregnant and n=5 non-pregnant) or 930 (n=6 pregnant and n=5 non-pregnant) mg choline/d. Fasting peripheral blood leukocyte samples were collected at week 0 and week 12 to extract RNA and perform the arrays. Healthy third trimester (gestational week 26-29) pregnant women and non-pregnant women were randomized to a 12-week choline controlled feeding study. The participants consumed either 480 (n=6 pregnant and n=5 non-pregnant) or 930 (n=6 pregnant and n=5 non-pregnant) mg choline/d for 12 weeks. Fasting (10-h) peripheral blood leukocyte gene expression were measured at week 0 and week 12.
