Heme oxygenase-1 protects donor livers from ischemia/reperfusion injury: The role of Kupffer cells

Figure 4 HO-1 and CD14 expression levels of cultured Kupffer cells. A: HO-1 mRNA expression levels of Kupffer cells were significantly downregulated in the ZnPP group and upregulated in the CoPP group. ZnPP treatment CD14 mRNA expression was expressed as relative increase compared with control. CoPP pretreated was lower (n = 4/group); B: Western blot analysis for CD14 protein of Kupffer cells. β-actin was used as internal control. CD14 protein expression levels increased in the ZnPP group and decreased in the CoPP group (n = 4/group). ^aP < 0.05, ^bP < 0.01.
