Effects of LAD ligation and GTPs on the myocardial content of LR, Cav-1, and Cav-3. (a) Western blotting with (b) quantitative analyses of 67 kD laminin receptor, Cav-1, and Cav-3 in the myocardium of sham controls (lane S) or post-LAD ligated rats with GTP supplementation (lanes 1, 2) or with water (lanes 3, 4) for 14 days. For post-LAD ligated rats supplemented with GTPs or water, cardiac tissues at the infarcted area (lanes 2, 4) and a remote myocardial site (lanes 1, 3) were isolated for analysis. Each group contains 5 animals for data analyses. The values are the means ± SEM, with *indicating a significant difference compared to the sham controls.
