Oleic Acid Induces Tissue-Resident FOXP3 Regulatory T Cell Suppressive Functions (bulk RNA)

ABSTRACT: Comparing the transcriptomic program induced by oleic acid to that of the pro-inflammatory arachidonic acid, we find that Tregs sorted from peripheral blood and adipose of healthy donors transcriptomically resemble the oleic acid in vitro treated Tregs, whereas Tregs obtained from the adipose tissue of relapsing-remitting MS patients more closely resemble an arachidonic acid profile

Brassica napus high oleic acid vs. low oleic acid

Project description:Compared to ordinary rapeseed, high-oleic acid rapeseed has higher levels of monounsaturated fatty acids and lower levels of saturated fatty acid and polyunsaturated fatty acids, and thus is of high nutritional and health value. In addition, high-oleic acid rapeseed oil imparts cardiovascular protective effects. Based on these properties, high-oleic acid oil crops have been extensively investigated and cultivated. In this study, we employed a microarray analysis with high oleic acid line and low oleic acid line from the developing seeds (27 days after flowering) of Brassica napus.

S. aureus gene expression following growth in media containing oleic acid

Project description:S. aureus response to exogenous fatty acid (oleic acid) Gene expression profiles were generated by microarray analysis of S. aureus cells grown in media without or with oleic aicd Comparison of expression profiles after growth of S. aureus in exogenous fatty acid S. aureus was grown in media with and without oleic acid to an OD600nm of 0.5, and RNA was extracted to look at the gobal gene expression.

Ferroptosis inhibition by oleic acid mitigates iron-overload-induced injury

Project description:Iron overload, characterized by accumulation of iron in tissues, induces a multiorgan toxicity whose mechanisms are not fully understood. Using cultured cell lines, Caenorhabditis elegans, and mice, we found that ferroptosis occurs in the context of iron-overload-mediated damage. Exogenous oleic acid protected against iron-overload-toxicity in cell culture and Caenorhabditis elegans by suppressing ferroptosis. In mice, oleic acid protected against FAC-induced liver lipid peroxidation and damage. Oleic acid changed the cellular lipid composition, characterized by decreased levels of polyunsaturated fatty acyl phospholipids and decreased levels of ether-linked phospholipids. The protective effect of oleic acid in cells was attenuated by GW6471 (a PPAR- antagonist), as well as in Caenorhabditis elegans lacking the nuclear hormone receptor NHR-49 (a PPAR- functional homologue). These results highlight ferroptosis as a driver of iron-overload-mediated damage, which is inhibited by oleic acid. This monounsaturated fatty acid represents a potential therapeutic approach to mitigating organ damage in iron overload individuals.

Adipose tissue nutrigenomic study in Iberian pigs with dietary intervention of oleic acid supplementation

Project description:We studied the influence of the oleic acid content of the diet on adipose tissue transcriptome. Iberian pigs were fed a standard (C) or a high oleic sunflower oil enriched (HO) diet. Transcriptome analyses were performed in adipose tissue samples (inner layer) obtained at slaughter (110 kg live weight) employing the Affymetrix porcine GeneChip. Normalized and filtered microarray expression data (background corrected and base-2 logarithmic-transformed) were analyzed through Bayesian inference using the GEAMM v.1.6 program. Statistically significant expression differences (FDR<0.10) between C and HO groups were observed for a total of ten probes corresponding to nine different known genes. Six genes were overexpressed in the HO group and three were overexpressed in the C group. Expression differences between groups ranged from 1.38 to 2.75-fold. The two most significantly DE genes were related with immune defense (TCRB and GPR183) and others were related with nutrient metabolism as glicerolipid metabolism (GK), phospholipid and sphingolipid metabolism (PPM1L), carbohydrate metabolism (FBP2) aminoacid metabolism and energy homeostasis (PRSS35 and CKB) and gene expression regulation and adipogenesis (RXRG). 15 Iberian castrated male pigs were adscribed to one of two experimental groups at 28 kg live weight (7 animals in Control group and 8 animals in High Oleic group). Nutritional treatment was maintained until sacrifice of the animals at 110 kg of live weight. At the sacrifice, backfat adipose tissue was sampled from each animal at the level of the last rib.

An immature high-oleic acid near-isogenic line of rapeseed

Project description:To identify differentially expressed proteins in a high-oleic acid rapeseed line, self-bred seeds (20 to 35 days after pollination) of a high- and a low-oleic acid rapeseed near-isogenic line (oleic acid contents of 81.4% and 56.2%, respectively) were used as raw materials for iTRAQ (isobaric tags for relative and absolute quantitation) analysis.
