In Utero Nutritional Manipulation Provokes Dysregulated Adipocytokines Production in F1 Offspring in Rats

الملخص EN

Background.

Intrauterine environment plays a pivotal role in the origin of fatal diseases such as diabetes.

Diabetes and obesity are associated with low-grade inflammatory state and dysregulated adipokines production.

This study aims to investigate the effect of maternal obesity and malnutrition on adipokines production (adiponectin, leptin, and TNF-α) in F1 offspring in rats.

Materials and Methods.

Wistar rats were allocated in groups: F1 offspring of control mothers under control diet (CF1-CD) and under high-fat diet (CF1-HCD), F1 offspring of obese mothers under CD (OF1-CD) and under HCD (OF1-HCD), and F1 offspring of malnourished mothers under CD (MF1-CD) and under HCD (MF1-HCD).

Every 5 weeks postnatally, blood samples were obtained for biochemical analysis.

Results.

At the end of the 30-week follow-up, OF1-HCD and MF1-HCD exhibited hyperinsulinemia, moderate dyslipidemia, insulin resistance, and impaired glucose homeostasis compared to CF1-CD and CF1-HCD.

OF1-HCD and MF1-HCD demonstrated low serum levels of adiponectin and high levels of leptin compared to CF1-CD and CF1-HCD.

OF1-CD, OF1-HCD, and MF1-HCD had elevated serum levels of TNF-α compared to CF1-CD and CF1-HCD ( p < 0.05 ).

Conclusion.

Maternal nutritional manipulation predisposes the offspring to development of insulin resistance in their adult life, probably via instigating dysregulated adipokines production.
