The expression of HNE, IL-6, TNF-α, and NF-κB p65 in the DCD heart preserved with EVHP. Representative photomicrographs and quantitative analysis of immunohistochemistry for (A) HNE, (B) IL-6, (C) TNF-α, and (D) NF-κB p65 in the DCD heart. Data represent mean ± standard error of the mean. n = 6–8 for each group. DCD, donation after circulatory death; EVHP, ex vivo heart perfusion; HNE, 4-hydroxynonenal; IL-6, interleukin-6; IOD, integrated optical density; TNF-α, tumor necrosis factor-α; NF-κB, nuclear factor kappa-B. p < 0.05 vs. Control; #p < 0.05 vs. DCD-vehicle.
