Transcription profiling of human aortic endothelial cells treated with with oligomeric procyanidins extracts

ABSTRACT: Human aortic endothelial cells were grown in culture until confluent. In three experiments using cells derived from three separate donors confluent cultures were incubated for 6 h with contol medium, or medium containing either extracts of oligomeric procyanidins from cranberry juice or red wine, or a procyanidin-rich grape seed extract. At the end of the 6 h treatment period conditioned media samples were retained for immunoassay of secreted peptides and proteins, and RNA was extracted for microarray analysis. Experiment Overall Design: Each experiment used cells from one donor. Treatment conditions were: control medium, cranberry extract (CRE), grape seed extract (GSE), and red wine extract (RWE).

Mechanistic insights into anti-cancer properties of oligomeric proanthocyanidins from grape seeds in colorectal cancer

Project description:Although the anti-cancer properties of Oligomeric Proanthocyanidins (OPCs) from grape seeds has been well recognized, the molecular mechanisms by which they exert anti-cancer effects are poorly understood. In this study, through comprehensive RNA-sequencing based gene-expression profiling in multiple colorectal cancer cell lines, we for the first time illuminate the genome-wide effects of OPCs from grape seeds in colorectal cancer. Our data revealed that OPCs affects several key cancer-associated genes. In particular, genes involved in cell cycle and DNA replication were most significantly and consistently altered by OPCs across multiple cell lines. Intriguingly, our in vivo experiments showed that OPCs was significantly more potent at decreasing xenograft tumor growth compared to the unfractionated grape seed extract (GSE) that includes the larger polymers of proanthocyanidins. These findings were further confirmed in colorectal cancer patient-derived organoids, wherein OPCs more potently inhibited the formation of organoids compared to GSE. Further, we validated alteration of cell cycle and DNA replication associated genes in cancer cell lines, mice xenografts as well as patient-derived organoids. Overall, this study provides an unbiased and comprehensive look at the mechanisms by which OPCs exerts anti-cancer properties in colorectal cancer.

Transcription profiling of 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. Experiment Overall Design: Primary cultures of hippocampal neurons were treated with 0, 1, or 10 ug/ml of GSE for 24 hrs. Primary cultures of hippocampal astrocytes were treated with 0, 1, 10, or 100 ug/ml of GSE for 24 hrs.

Transcriptomic profiling of human senescent cells in the setting of grape seed extract intervention

Project description:Aging and age-related pathologies can be delayed by specifically targeting the senescence-associated secretory phenotype (SASP), a hallmark feature of senescent cells. Achieving the goal using small molecule inhibitors would have a tremendous impact on the quality of lifespan and burden of age-related chronic diseases. We report the potential of grape seed extract (GSE), a naturally existing source of phytochemicals including terpenoids, carotenoids, and flavonoids, in targeting senescent cells via induction of programmed cell death. This study demonstrates the impact of GSE as a medicinal compound on the expression profile of senescent cells and provides a strong rationale for its future use in geriatric medicine.

Transcription profiling of healthy human volunteers after consumin red wine vs. controls to investigate the cardioprotective effect of red wine

Project description:The aim of this study was to measure the influence of beverages on blood gene expression. We wanted to explore the underlying mechanisms of the cardioprotective effects of red wine. Experiment Overall Design: Six healthy volunteers participated in this randomized controlled cross-over experiment. On 4 independent days they had 4 different beverages (500mL each: grape juice, red wine, 40g diluted ethanol, water). Blood samples were taken at baseline, 1, 2, 4, 12 hours after the drink together with standardized nutrition. RNA of 120 PBL samples was hybridized on Affymetrix microarrays. Three sources of variations were examined: individual, time and beverage.

Transcriptome analysis of response to exogenous trehalose and abiotic stress in grapes

Project description:Grapevine is an important economic fruit tree, and European grape (Vitis vinifera L.) has been widely used in fresh food, drying, winemaking and grape seed extract. However, most European grapes have low resistance to low temperature, drought and salt stress, and these abiotic stresses will limit the growth and development of grapes, thereby affecting the grape quality and yield. Many reports have shown that exogenous or endogenous trehalose can help improve plant stress resistance. Therefore, in order to investigate the function and molecular mechanism of trehalose metabolism in grape response to stress, this project was conducted.

Developmental and metabolic plasticity of ripe Sémillon grape berries in response to Botrytis cinerea during noble rot

Project description:Noble rot results from atypical infections of ripe grape berries by Botrytis cinerea. Unlike bunch rot, noble rot promotes favorable changes in grape berries and accumulation of secondary metabolites that enhance wine grape quality. Noble rot-infected berries of Sémillon, a white-skinned variety, were collected over three years from a commercial vineyard at the same time fruit were harvested for botrytized wine production. Transcriptomic and metabolomic data were integrated to identify pathways associated with distinct stages of noble rot. Botrytis induced the expression of known key regulators of pathways in secondary metabolism associated with berry ripening. The activation by Botrytis during noble rot of metabolic pathways associated with berry ripening was further supported by comparisons with transcriptomes of red-skinned varieties at véraison. A prominent and common outcome of noble rot and berry ripening was the enhancement of the phenylpropanoid metabolism. Induced synthesis of stilbenes, flavonoids, and anthocyanins was supported by both transcriptional and metabolite analyses. Enzyme assays and targeted gene expression analyses of samples from the three distinct years confirmed that the activation of central and peripheral phenylpropanoid pathways is a consistent hallmark of noble rot. Finally, we show that the impact of noble rot on grape metabolism is still detectable in botrytized wines. These results demonstrate that despite the late stage of terminal senescence of a plant organ, a biotic stress can cause a major reprogramming of plant metabolism leading, in case of noble rot, to the synthesis of important metabolites for grape berry flavor and aroma.

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.
