Maternal hyperlipidemia is associated with sustained elevated blood pressures, enhanced contraction, and reduced relaxation functions of the mesenteric arteries. (A) Tail cuff systolic blood pressures (SBP) in male chow-exposed and high-fat-diet (HFD)-exposed offspring (n = 6 for each group). (B) Tail cuff SBP in female chow-exposed and HFD-exposed offspring (n = 6 for each group). (C) Intra-arterial cannulation SBP in 6-month-old chow-exposed and high-fat-diet (HFD)-exposed offspring (n = 5 for each group). (D) The contractile responses of the mesenteric arteries to phenylephrine in one-year-old HFD-exposed and control male rat offspring (Phe, n = 3). The concentration for 50% of the maximal effect (EC50) in contraction is 3.973 × 10–6 M (Chow-F1) and 2.063 × 10–6 M (HFD-F1). (E) The endothelium-dependent vasorelaxation in the mesenteric arteries of one-year-old HFD-exposed and control male rat offspring (n = 3). The concentration for 50% of the maximal effect (EC50) in relaxation is 3.794 × 10–8 M (Chow-F1) and 1.705 × 10–7 M (HFD-F1). Values in (A,B) are expressed as means ± SEs, ***p < 0.0001 **p < 0.01, *p < 0.05, compared to the corresponding control.
