Project description:Obesity and its consequences on cardiometabolic health have been associated to low-grade inflammation. The most diverse source of dietary anti-inflammatory compounds is polyphenols and especially anthocyanins, which are major polyphenols in bilberries (Vaccinium myrtillus). We investigated the effects of a bilberry-rich diet on glucose and lipid metabolism, inflammation and gene expression profile in peripheral blood mononuclear cells (PBMCs) in subjects with overweight and other features of the metabolic syndrome. The study was a randomized, controlled clinical intervention using 2-arm parallel group design. The participants in the bilberry group (BB, n = 15) consumed bilberries or berry products equivalent of 400 g fresh bilberries daily for 8 weeks, while the participants in the control group (C, n = 12) were asked to maintain their habitual diet. The microarray profiling was done from 3 subjects in the BB group and further QPCR expression analyses from all subjects in both groups at the start and end of the intervention (weeks 0 and 8). From 50 differentially expressed transcripts (P<0.005), five candidate genes; WDSUB1, COX7B, RGS18, DAPP1 and TICAM1, were randomly selected for QPCR analyses from PBMCs in both groups. To further explore the interplay of dietary change and activated pathways in PBMCs, 11 additional genes were selected for QPCR. The selected transcripts were from the LPB, RIPK-1, Ly96 (MD2), CD19, MMD, TNFRSF12A, CD72, CCR2, IL17RC, IL17R and MAP3K7IP2 genes. Our results indicate that regular bilberry intake may reduce endotoxemia and chronic inflammation, the latter especially by directing the immunity away from overactive innate cell mediated responsiveness. Bilberry consumption may decrease cardiovascular and metabolic risk in the long term.

Project description:Obesity and diabetes associated visual impairment and vascular dysfunctions are increasing reasons for vision loss. The detailed mechanisms in these diseases are still largely unknown, but mice models have been useful to study these mechanisms and explore the detailed effects of potential compounds. Such compounds usually have antioxidant and anti-inflammatory properties. These properties are found in anthocyanins and a major source of dietary anthocyanins in Nordic diet is bilberries (European wild blueberries, Vaccinium myrtillus). In this explorative study we show results with differentially expressed genes in retina using a high-fat diet (HFD) mouse model. Our findings displayed differential regulation of genes in pathways for apoptosis, inflammation and oxidative stress, especially systemic lupus erythematosus (SLE), mitogen activated protein kinase (MAPK) and glutathione metabolism. Mice fed with HFD had increased retinal gene expression of several crystallins, which was reduced in the retina of mice fed with bilberries. Bilberries seem to reduce the expression of genes in MAPK and to increase the expression of genes in glutathione metabolism pathway. All together despite minor effects in the mouse phenotype, a diet rich in bilberries may prevent the retinal gene expression changes in the early stages of obesity. Mice were fed ad libitum with normal control diet (NCD, 10% kcal fat), high-fat diet (HFD, 45% kcal fat), 5% (w/w) freeze-dried biberries (Vaccinium myrtillus) in NCD (NCD+BB) or HFD (HFD+BB) for 12 weeks. Diets were prepared in Research Diets Inc. Feed consumption and weight gain were measured during the feeding trial, and blood pressure and serum markers of obesity at the end. Retinas were collected and RNA extracted from all 24 mice samples, and pooled retinas from 4 mice per group were hybridized with standard Illumina protocols. The expression in retinas was analyzed using R, Pathvisio and DAVID to screen for differences between high-fat and berry induced changes to control diets and further bilberry induced changes to HFD up- or downregulated transcripts. diet: NCD, HFD, NCD+BB, HFD+BB

Project description:To better understand the role of phenylpropanoid pathway perturbation in plant metabolism, Populus tremuloides cell cultures previously established from leaf mesophyll tissue were fed with methyl jasmonate, alpha-aminooxy-beta-phenylpropionic acid (AOPP), or both approximately 5 days after transfer to fresh medium. Methyl jasmonate is an elicitor that activates a suite of defense responses including phenylpropanoid metabolism. In contrast, AOPP acts as an inhibitor of phenylalanine ammonia lyase (PAL). Samples were harvested 48 hrs after initiation of the experiment. Total RNA was extracted and gene expression measured using Affymetrix poplar genome microarrays.

Project description:To better understand the role of phenylpropanoid pathway perturbation in plant metabolism, Populus tremuloides cell cultures previously established from leaf mesophyll tissue were fed with piperonylic acid (PIP) alone, or in combination with methyl jasmonate (MJ_PIP) approximately 5 days after transfer to fresh medium. Methyl jasmonate is an elicitor that activates a suite of defense responses including phenylpropanoid metabolism, while PIP acts as an inhibitor of cinnamate-4-hydroxylase (C4H). Sample tissues were contemporary with those used to generate Series GSE16773. Samples were harvested 48 hrs after initiation of the experiment. Total RNA was extracted and gene expression measured using Affymetrix poplar genome microarrays.
