Scope

Resveratrol (RSV) and nicotinamide riboside (NR) are food compounds with anti-obesity actions in adult rodents. Here we assessed the long-term effects of RSV and NR mild supplementation throughout lactation on adiposity-related parameters and the appearance of the beige phenotype in white adipose tissue (WAT) in adulthood.

Methods and Results

Newborn mice received orally RSV or NR from day 2 to 20 of life. Control littermates received the vehicle. All animals were weaned onto a chow diet on day 21. On day 90, half the animals of each group were assigned to a high-fat diet (HFD) for 10 weeks, while the other remained on a normal-fat diet. Energy balance-related parameters, blood parameters, and gene expression and immunohistochemical analysis of WAT were assessed. Treated male mice showed an improved response to the HFD, such as delayed body weight gain, a blunted increase in the plasma leptin/adiponectin ratio, and a decreased lipolytic response, together with signs of white-to-brown fat remodeling in inguinal WAT. These effects were absent in female mice.

Conclusions

RSV and NR supplementations in early postnatal life affect WAT's thermogenic/oxidative transcriptional phenotype and metabolic responses in adulthood, with upregulatory and beneficial effects evidenced in male animals. This article is protected by copyright. All rights reserved.
