GNPS - Dietary intake of a milk sphingolipid-rich MFGM/EV concentrate ameliorates age-related metabolic dysfunction | Plasma | Sprenger et al. 2025

ABSTRACT: Lipidomic analysis of plasma samples from aged rats +/- dietary intervention with an MFGM/EV-rich concentrate. In short, 10 plasma samples per intervention group were analyzed by MSaLL analysis. Uploaded data includes .raw files, ALEX123 search results, a sample list as well as a list with spike amounts of internal lipid standards. A detailed description of the analysis is provided in the publication with the title: Dietary intake of a milk sphingolipid-rich MFGM/EV concentrate ameliorates age-related metabolic dysfunction.

Project description:Some studies have shown that acute intake of high-phenol virgin olive oil reduces pro-inflammatory, pro-oxidant and pro-thrombotic states, but nowadays still remains unclear if those effects attributed to its phenolic fraction could be exerted at transcriptional level in vivo. Two virgin olive oil-based breakfasts with high (398 ppm) and low (70 ppm) content of phenolic compounds were administered to twenty patients (9 men and 11 women) with metabolic syndrome following a double-blinded random crossover design. Prior to the first breakfast intervention, participants followed a 6-week washout period in which they were instructed to not take vitamins, soy supplements, or any drug. To eliminate the potential effect that might exist in their usual dietary habits, all subjects followed a low-fat, carbohydrate rich (CHO) diet during this period and untill the end of the study. In the 24 h before each breakfast intervention, participants were instructed to avoid consuming phenol-rich foods such as fruit or juices, wine, grape juice, chocolate, coffee, tea, olive oil, or soya, and to refrain from intense physical exercise during that period. After a 12 h fasting and following a randomized sequential crossover design with one-week washout period, participants reported to the hospital and received two fat meals consisting of 60 g of white bread, 40 mL of VOO (CANOLIVA®, Antonio Cano e Hijos™, Córdoba, Spain) with high (398 ppm) or low (70 ppm) content in phenolic compounds, and 60,000 IU of vitamin A per m2 of body surface. Olive oil with low content in phenolic compounds was obtained as a result of extraction by physical procedures of most of the phenolic compounds in the high-phenol olive oil, so that both oils kept a similar composition of the remaining macro- and micronutrients. Throughout the 4-h duration of the study, the subjects performed no physical activity, nor did they consume anything but water. Gene expression was performed on peripheral blood mononuclear cells (PBMCs) at postprandial period (4 hours after breakfast) by microarray analysis and verified by qRT-PCR. Two sets of dye-swaped experiments were performed making a total of four technical replicates per subject. Each of the hybridizations compared total RNA from PBMCs obtained 4h after the intake of virgin olive oil with high phenolic content vs. total RNA from PBMCs obtained 4h after low-phenol virgin olive oil consumption.
