The expression of RelA/p65 in human samples. (a) The expression of p65 was detected by immunohistochemistry in human samples. Bars indicate 200 μm. (b) Significant difference in p65 expression level between normal and fibrotic tissues. Results were expressed as percentage density for five independent samples, and P-values were determined using paired t-test. **P<0.01. (c) Western blot analysis of the relative levels of p-p65, Col I, Col III, and α-SMA protein expression in normal (N) and fibrotic (F) tissues of six patients. Densitometric analysis of p-p65, Col I, Col III, and α-SMA expression. Statistical significance was calculated using paired Student t-test for ten pairs of samples. The data are shown as the means±S.D. *P<0.05. **P<0.01
