Prenatal stress programs lipid metabolism enhancing cardiovascular risk in the female F1, F2, and F3 generation in the primate model common marmoset (Callithrix jacchus)

Abstract

Background: Many human diseases are modulated by intrauterine environment, which is called prenatal programming. This study investigated effects of prenatal glucocorticoids on the lipid metabolism of three filial generations of common marmosets.

Methods: Pregnant primates were treated with dexamethasone during pregnancy. Body weight and blood lipid parameters of adult female offspring (F1: n = 5, F2: n = 6, F3: n = 3) were compared with age-related female controls (n = 12).

Results: F1, F2, and F3 offspring showed significantly lower percentage of plasma n3 fatty acids than controls. F2 and F3 presented higher cholesterol levels, with significantly more LDL cholesterol, significantly less HDL triglycerides and an enhanced cholesterol/HDL cholesterol ratio. Body weight was not significantly affected.

Conclusions: Prenatal dexamethasone led to higher amounts of cardiovascular risk factors and less protective parameters in female F1-F3 offspring. The intergenerational consequences suggest prenatal programming through epigenetic effects.
