Abstract

The aim of the present study was to test whether the administration of a grape seed procyanidin extract (GSPE) during pregnancy and lactation, at doses extrapolated to human consumption, programs male offspring toward improved metabolism in adulthood. For this purpose, female rats were fed a normal-fat diet (NFD) and treated with either GSPE (25 mg kg(-1) of body weight/day) or vehicle during gestation and lactation. The metabolic programming effects of GSPE were evaluated in the male offspring fed NFD from 30 to 170 days of life. No changes were observed in body weight, adiposity, circulating lipid profile and insulin sensitivity between the offspring of dams treated with GSPE (STD-GSPE group) and their counterparts (STD-veh). However, the STD-GSPE offspring had lower circulating levels of C-reactive protein and lower respiratory quotient values, shifting whole-body energy catabolism from carbohydrate to fat oxidation. Furthermore, the STD-GSPE animals also exhibited increased levels of total and phosphorylated AMP-activated protein kinase (AMPK) and an over-expression of the mRNA levels of key genes related to fatty acid uptake (Fatp1 and CD36) and β-oxidation (pparα and had) in skeletal muscle. Our results indicate that GSPE programs healthy male offspring towards a better circulating inflammatory profile and greater lipid utilisation in adulthood. The metabolic programming effects of GSPE that are related to the enhancement of fatty acid oxidation in skeletal muscle seem to be mediated, at least in part, by AMPK. These findings could be of relevance in the prevention of pathologies associated to lifestyle and aging, such as obesity and insulin resistance.
