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.
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.
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.

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.
Project description:To unfold the potential links between Salmonella fatty acid oxidation and other metabolic pathways, we performed RNA-seq to draw the transcriptomic response of Salmonella in response to oleci acid treatment. We compared samples of oleic acid shock (Group OAS) and oleic acid growth (Group OAG) to glucose growth (Group GLU).
Project description:Here we investigated the transcriptomic changes induced by oleic acid treatment on human Primary Renal Proximal Tubule Epithelial Cells (RPTECs) with RNA-seq. We also profiled cells with oleic acid treatment after PLIN2 gene knockdown with siRNA treatment.
