Figure 3 A. Representative RT-PCR photographs for TGF-ß1, MCP-1, and GAPDH mRNA expression in the left ventricle of age-matched LETO, untreated-OLETF, and treated-OLETF rats at 30 weeks. B. Quantitative comparison of the mRNA expression for TGF-ß1 (left) and MCP-1 (right) in the left ventricle among the groups. Values are the percentage of GAPDH as the control and expressed as mean ± SD (n = 5 for each group). *p < 0.05 versus LETO rats; p < 0.05 versus untreated-OLETF rats. Abbreviations as in Figure 1.
