Comparative transcriptomic profiling of peripheral blood mononuclear cells (PBMCs) isolated from patients in secondary prevention of CVD taking placebo, grape extract or resveratrol-enriched grape extract

ABSTRACT: We used Affymetrix microarrays to investigate gene expression changes in PBMCs isolated from male patients ongoing secondary prevention of CVD to determine significant modulatory effects that may have been induced by the intake of an initial dose of 8 mg of resveratrol-enriched grape extract for 6 months and then, 16 mg for a further 6 months. The aim of this work was to determine whether the daily intake of dietary levels of resveratrol (RES) for a total of 12 months exerted any modulatory effects, at the level of gene expression, in PBMCs isolated from patients in secondary prevention of CVD. Male patients were divided in 3 groups: placebo (A), grape extract (B) and resveratrol-enriched grape extract (C). Total RNA was extracted from isolated PBMCs belonging to a total of 18 diabetic male patients (6 from each group) in 3 time points (at day 0, after 6 months and after 12 months) to compare differential gene expression between the groups. Differential gene expression after 6 and 12 months of the study for each group: placebo (A), grape extract (B) and resveratrol-enriched grape extract (C)

Comparative transcriptomic profiling of peripheral blood mononuclear cells (PBMNCs) isolated from pigs exposed to an atherogenic diet (AD) or to an AD supplemented with Grape Extract (GE) and/or Resveratrol (RES).

Project description:We used Affymetrix microarrays to investigate gene expression changes in PBMNCs isolated from female and male pigs to determine significant modulatory effects that may have been induced by the intake of GE and (or) RES during 4 months in animals fed an atherogenic diet (AD) . The aim of this work was to determine whether the intake of low doses of a Grape Extract (GE; 1 g/70 Kg animal body weight) and (or) Resveratrol (RES; 18 mg/70 Kg animal body weight) exerted any modulatory effects, at the level of gene expression, in PBMNCs isolated from female and male pigs exposed to an atherogenic diet (AD) for 4 months. We isolated PBMNCs, and the corresponding total RNA, from 2 female and 2 male pigs for each group. Pure RNA was extracted from the PBMNCs for microarrays analyses (Affymetrix) and gene differential expression determined between the AD fed animals and control (CT) animals (to determine the effects of a high-fat consumption) and between the AD fed animals supplemented with GE and (or) RES and the animals fed the AD diet alone (to determine the effects of GE and (or) RES on the fat consumption). In addition, the effects of the consumption of GE and RES against a standard control diet (CT) were also determined. Differential gene expression: 1) AD vs CT (response to exposure to a high-fat diet); 2) AD-GE vs AD (modulatory effects of the intake of a grape extract on high-fat fed animals); 3) AD-GE-RES vs AD (modulatory effects of the intake of a resveratrol-enriched grape extract on high-fat fed animals); 4) AD-RES vs AD (modulatory effects of the intake of resveratrol on high-fat fed animals); 5) CT-GE-RES vs CT (modulatory effects of the intake of a resveratrol-enriched grape extract on animals fes a standard pig chow).

Transcriptome analyses of grape berry skin induced by UV irradiation.

Project description:We conducted transcript profiling and metabolome profiling induced by UV irradiation in grape berry skin. Transcriptome analysis was carried out with genome-wide microarray and two hundred thirty eight genes were more than 5-fold up-regulated by UV irradiation. The enrichment analysis showed GO terms including stilbene synthase (STS) gene. Moreover, the principal component analysis (PCA) of metabolome analysis showed a compound, identified resveratrol, accumulated in grape berry skin specifically. Our result clearly shows that UV irradiation induced only accumulation of resveratrol and its analogues but did not induce accumulation of the other phenolic compounds.

Gene expression in neurons or astrocytes treated with grape seed extract

Project description:We examined the effect of grape seed extract (GSE), which are known to protect neurons against oxidative stress, on primary cultures of hippocampal astrocytes. GSE increased interleukin-6 (IL-6) expression. Microarrays are used to examine the effects of GSE on primary cultures of hippocampal neurons and astrocytes.

Comparative transcriptomic profiling of peripheral blood mononuclear cells (PBMNCs) isolated from pigs exposed to a high-fat diet (H-F) or to a high-fat diet plus resveratrol (H-F+RES)

Project description:We used Affymetrix microarrays to investigate gene expression changes in PBMNCs isolated from female and male pigs to determine significant modulatory effects that may have been induced by the intake of resveratrol during 9 months in high-fat fed animals . The aim of this work was to determine whether the intake of dietary levels of resveratrol (RES) exerted any modulatory effects, at the level of gene expression, in PBMNCs isolated from female and male pigs exposed to a H-F diet for 9 months. We first isolated PBMNCs, and the corresponding total RNA, from 5 female pigs and 5 male pigs at time 0 (beginning of the experiment) to determine basal gene expression levels and to compare sex differential gene expression. Animals designated to the control group were then fed a normal chow (5% beef tallow) for 9 months. Animals in the H-F diet were fed a chow with 20% of beef tallow and animals in the H-F diet supplemented with resveratrol were fed the 20% fat diet plus resveratrol (8 mg/Kg body weight per day). From each group, PBMNCs were isolated from 2 female and 2 male animals. Pure RNA was extracted from the PBMNCs for microarrays analyses (Affymetrix) and gene differential expression determined between the H-F fed animals and CT animals (to determine the effects of fat consumption) and between the H-F fed animals supplemented with RES and the H-F group (to determine the effects of RES on the fat consumption).

Synbiotic-Derived Metabolites Alleviate Stress-Induced Depression by Regulating Lymphocyte Activation through the Aryl Hydrocarbon Receptor

Project description:Synbiotics are a combination of probiotics and prebiotics which can alter the composition of the gastrointestinal tract evoking beneficial effects throughout the body through the production of a battery of bioactive metabolites. In this study, a synbiotic was used to reduce the behavioral and biochemical symptoms of depression and this nanostring panel was used to decipher where along the gut-brain-axis the synbiotic-derived metabolites were invoking their beneficial effects on the immune system. The synbitoic was composed of two probiotic bacteria (Lactobacillus fermentum ATCC 793 and Bifidobacteria longum ATCC 15707 and a grape -derived prebiotic composed of grape seed polyphenol extract, resveratrol and a concord grape extract. Male mice (C57BL/6) were pretreatment with either nothing (control), BDPP, probiotic or synbiotic and underwent 28 days of chronic unpredicitable stress. After 28 days, animals' behavior reflected an increase in depressive- and anxiety-like behavior, rescued specifically by the synbiotic. This nanostring multiplex analysis reveals both tissue- and treatment-specific effects on immune modulators.
