Abstract

Maternal factors can have major imprinting effects on homeostatic mechanisms in the developing fetus and newborn. Here we studied whether supplemented perinatal polyunsaturated fatty acids (PUFAs) influence energy balance and fuel homeostasis later in life. Between day 10 after conception and day 10 after delivery, female rats were subjected to chow enriched with 10% fish-oil (FO-rich). Fish oil contains high concentrations of n-3 biosynthesis endpoint products, which may have caused the increased membrane phospholipid incorporation (particularly derived from the long-chain 20 +:n-3 PUFAs) in 10-day old pup brains. Adult male offspring of FO-rich fed rats had reduced body weight (− 20%) at 3 months, and had lower levels of plasma leptin (− 54%), insulin (− 41%), triglycerides (− 65%), and lactate (− 46%) than controls. All differences between groups were lost 48 h after streptozotocin (STZ) treatment. At 4.5 months of age, body weights of FO-rich were still lower (− 6%) than controls, but were associated with increased food intake, and increased insulin sensitivity (following intraperitoneal injection) to lower blood glucose levels relative to controls. We concluded that perinatal FO supplementation has lasting effects on body weight homeostasis and fuel metabolism in male offspring, but does not offer resistance against STZ-induced diabetes.
