Project description:Objective: Procyanidins are polyphenolic bioactive compounds that exert beneficial effects against obesity and its related diseases. The aim of this study was to evaluate whether the supplementation with low doses of a grape seed procyanidin extract (GSPE) to dams during pre and postnatal periods has biological effects on their offspring at youth. Design: The metabolic imprinting effect of GSPE was evaluated in 30 days-old male offspring of four groups of rats that were fed either a standard diet (STD) or a high-fat diet (HFD) and supplemented with either GSPE at 25 mg per kg of body weight/day or vehicle during pregnancy and lactation. Results: A significant increase in the adiposity index and in the weight of all the white adipose tissue depots studied (retroperitoneal â??RWAT-, mesenteric â??MWAT-, epididymal â??EWAT- and inguinal â??IWAT-) was observed in offspring of dams fed with a HFD and treated with GSPE (HFT group), compared to the offspring of dams fed with the same diet and that do not received procyanidins (HF group). HFT animals also showed a higher number of cells in the EWAT, a sharply decrease of the circulating levels of monocyte chemoattractant protein-1 (MCP-1) as well as a moderate, but significant, decrease of plasma glycerol levels. The transcriptomic analysis performed in the EWAT showed 238 genes differentially expressed between HF and HFT animals, covering an entire range of processes related with the immune function and the inflammatory response (the metabolic pathway mainly reflected in the EWAT), adipose tissue remodeling and function, lipid and glucose homeostasis and metabolism of methyl groups. Conclusion: GSPE treatment to dams fed a HFD during pregnancy and lactation increases adiposity, decreases the circulating levels of MCP-1 and modulates the expression of key genes involved in the adipose tissue metabolism of their offspring. The microarray study was performed with the EWAT RNA samples of rats from the HF and the HFT groups (n=8 animals each).
