Relative Expression of CD105 and HIF-1alpha antigens in normal, non-tumor (TF and AT), and tumor tissues. CD105 and HIF-1alpha antigens were detected by Western blotting analysis in 16-paired samples, and the representative data were presented. A, Proteins in lanes 1–3 were extracted from TF, AT, and TT of patient 155, respectively; lanes 4–6 from TF, AT, and TT of patient 167, and lanes 7 and 8 from normal tissues of two healthy controls. B, Fold of CD105 and HIF-1alpha represented the mean of the relative fold from 8 independent experiments (HC, n = 8; TF, AT, and TT, n = 16). Relative fold refers to the ratio of CD105 or HIF-1alpha intensity in TF, AT, and TT to that in HC (* = p <0.05, ** = p < 0.01, versus HC; ^# = p < 0.05, ^## = p < 0.01, versus TT). Columns, mean; bars, SD.
