Maternal high-fat diet triggers lipotoxicity in the fetal livers of nonhuman primates.

Maternal obesity is thought to increase the offspring's risk of juvenile obesity and metabolic diseases; however, the mechanism(s) whereby excess maternal nutrition affects fetal development remain poorly understood. Here, we investigated in nonhuman primates the effect of chronic high-fat diet (HFD) on the development of fetal metabolic systems. We found that fetal offspring from both lean and...

Maternal High Fat Diet Is Associated with Decreased Plasma n–3 Fatty Acids and Fetal Hepatic Apoptosis in Nonhuman Primates

To begin to understand the contributions of maternal obesity and over-nutrition to human development and the early origins of obesity, we utilized a non-human primate model to investigate the effects of maternal high-fat feeding and obesity on breast milk, maternal and fetal plasma fatty acid composition and fetal hepatic development. While the high-fat diet (HFD) contained equivalent levels of...

Resveratrol Prevents β-Cell Dedifferentiation in Nonhuman Primates Given a High-Fat/High-Sugar Diet

Eating a "Westernized" diet high in fat and sugar leads to weight gain and numerous health problems, including the development of type 2 diabetes mellitus (T2DM). Rodent studies have shown that resveratrol supplementation reduces blood glucose levels, preserves β-cells in islets of Langerhans, and improves insulin action. Although rodent models are helpful for understanding β-cell biology and c...

Maternal high-fat diet and obesity compromise fetal hematopoiesis

OBJECTIVE Recent evidence indicates that the adult hematopoietic system is susceptible to diet-induced lineage skewing. It is not known whether the developing hematopoietic system is subject to metabolic programming via in utero high-fat diet (HFD) exposure, an established mechanism of adult disease in several organ systems. We previously reported substantial losses in offspring liver size with...

Protective effects of troxerutin on maternal high-fat diet-induced impairments of spatial memory and apelin in the male offspring

Objective(s): Maternal high-fat diet (HFD) is linked with metabolic and cognitive deficits in offspring. Neuroprotective effects of troxerutin, a natural bioflavonoid, have been reported recently. This study aimed to investigate the effects of troxerutin on spatial memory and serum and hippocampal apelin levels in the male offspring of HFD fed mothers.Materials and Methods: Three-week-old femal...
