Abstract

Intrauterine growth restriction (IUGR) confers heritable alterations in DNA methylation, rendering risk of adult metabolic syndrome (MetS). Because CpG methylation is coupled to intake of essential nutrients along the one-carbon pathway, we reasoned that essential nutrient supplementation (ENS) may abrogate IUGR-conferred multigenerational MetS. Pregnant Sprague-Dawley rats underwent bilateral uterine artery ligation causing IUGR in F1. Among the F2 generation, IUGR lineage rats were underweight at birth (6.7 vs. 8.0 g, P < 0.0001) and obese by adulthood (p160: 613 vs. 510 g; P < 0.0001). Dual energy X-ray absorptiometry studies revealed increased central fat mass (Δ+40 g), accompanied by dyslipidemic (>30% elevated, P < 0.05) serum triglycerides (139 mg/dl), very-LDLs (27.8 mg/dl), and fatty acids (632 μM). Hyperglycemic-euglycemic clamp studies and glucose tolerance testing revealed insulin resistance. Conversely, IUGR lineage ENS-fed rats did not manifest MetS, with significantly lower body weight (p160: 410 g), >5-fold less central fat mass, normal hepatic glucose efflux, and >70% reduced circulating triglycerides and very- LDLs compared with IUGR control-fed F2 offspring (P < 0.01). Moreover, increased methylation of the IGF-1 P2 transcriptional start site among IUGR lineage F2 offspring was reversed in ENS (P < 0.04). This is an initial demonstration that supplementation along the one-carbon pathway abrogates adult morbidity and associated epigenomic modifications of IGF-1 in a rodent model of multigenerational MetS.
