N normal phenotype
cardiovascular system
• thinner arterial wall
• the interventricular septum is partially flattened at P5 and P9
• the interventricular septum lacks the normal curvature which results in a D-shaped left ventricle
• reduction in width of the interventricular septum at P5 and P9, but not at P2
• enlargement of the left ventricle at P5 and P9
• interstitial fibrosis due to oxidative stress is initiated at P2 and progresses rapidly
• electrocardiogram indicates longer R-R intervals

cellular
• interstitial fibrosis due to oxidative stress is initiated at P2 and progresses rapidly
• marker analysis indicates oxidative stress in the heart
