Epidemiological data in humans and experiments in laboratory animals have demonstrated that the developmental programming of hypertension may occur as a consequence of dietary manipulations during pregnancy. Surprisingly, there is a scarcity of data regarding the development of hypertension as a consequence of a maternal low-protein diet (MLPD), particularly in the mouse. Furthermore, the role of sex in developmental programming is not well understood. We used FVB/NJ mice, because of their value in genetic/mechanistic analysis, to test the hypothesis that a MLPD during gestation leads to the sexually dimorphic developmental programming of hypertension and related disorders, such as intra-uterine growth restriction (IUGR), type 2 diabetes mellitus and obesity. We administered iso-caloric, normal (control), moderate protein (moderate MLPD) and severe protein (severe MLPD) diets to the mice …
