Abstract

Objective(s): Maternal high-fat diet has been shown to have deleterious effects on the offspring bones. However, there is no study to assess the effects of type and amount of maternal dietary oil in an isocaloric diet, with focus on extra virgin olive oil (EVOO). The objective of the current study was to test the hypothesis that type of maternal dietary oil has more effects than its amount in an isocaloric diet during gestation and lactation on bone genes expression in offspring in adolescence. Materials and Methods: Virgin female C57BL/6 mice were impregnated and fed either the AIN 93G diet (received 16 of calories as soybean oil, as a control diet, or EVOO) or a high fat AIN 93G diet (received 45 of calories as soybean oil or EVOO) from the time of vaginal plug confirmation until offspring’s weaning. Results: After adjusting for the amount of oils, osteoprotegerin/ receptor activator of nuclear factor NF-κB ligand (OPG/RANK-L) and OPG expressions were 6.1- and 2.8-folds higher in offspring born to EVOO compared with soybean oil-fed mothers. OPG, beta-catenin, and OPG/RANK-L expression were 88, 94, and 70 lower in offspring born to the 45 oil-fed mothers compared with the 16 group. In contrast, peroxisome proliferator-activated receptor gamma-2 (PPARγ2) gene expression was higher in the 45 oil group, adjusted for the types of oil. Conclusion: Maternal EVOO consumption, but not soybean oil increased osteoblastic gene expression, and high amounts of both oils decreased osteoblastic and increased adipogenic genes expression in adolescent offspring.
