Relaxin deficiency reduces femoral artery volume compliance at 3 months of age. Volume compliance against intraluminal pressure of femoral arteries from Rln ^+/+ (closed square) and Rln ^−/− (open square) mice at 3 (a), 12 (b), and 23 (c) months of age and area under curve (AUC) analysis of both genotypes at all ages (d). Values are mean ± SEM. *Significantly (P < 0.05) less than Rln ^+/+ mice, ^#significantly less than 3-month-old Rln ^+/+ mice, ^†significantly less than 3-month-old Rln ^−/− mice, n = 6–9
