The effects of losartan on inflammatory gene expressions assessed by qRT-PCR at weeks 1, 3, and 15. Expression of (a) interleukin-1 (Il1), (b) interleukin-6 (Il6), (c) tumor necrosis factor-alpha (Tnfα), (d) matrix metalloprotease-2 (Mmp2), and (e) chymase (Cma) normalized to ribosomal protein lateral stalk subunit P2 (RpIp2) gene expression were measured in left ventricle samples. Values are presented as mean ± S.E.M., * p < 0.05 vs. control group, # p < 0.05 vs. RT only group (n = 6–7, One-Way ANOVA, Holm-Sidak post hoc test). Ctrl: control group, RT: radiotherapy only group (50 Gy), RT Los: RT plus losartan group.
