FIGURE 3.
Structural and mechanical changes in left anterior descending (LAD) coronary artery from male diabetic mice. (A,B) Increasing pressure (10–140 mmHg) changes in external (De) and internal (Di) diameters, (C,D) wall thickness, (E,F) wall:lumen ratio, and (G,H) incremental distensibility. The vessel wall thickness is significantly lower in male mice, while distensibility is significantly higher in arteries from male db/db mice and significantly lower in arteries from female db/db mice compared to the db/db+ controls. The results are means ± SEM. *P < 0.05, db/db (n = 6) versus db/db+ controls (n = 6).
