BACKGROUND: A fusion protein composed of heme oxygenase-1 (HO-1) and
cell-penetrating peptide PEP-1 has been shown to reduce local intestinal injury
after intestinal ischemia/reperfusion (I/R). In this study, we investigated the
effects of PEP-1-HO-1 fusion protein on remote organ injury induced by intestinal
I/R in rats. MATERIAL AND METHODS: We randomly assigned 24 male Sprague-Dawley
rats to 3 groups: Sham, I/R, and I/R plus PEP-1-HO-1 treatment (HO). The model of
intestinal I/R was established by occluding the superior mesenteric artery for 45
min followed by 120-min reperfusion. In HO group, PEP-1-HO-1 was administered
intravenously 30 min before ischemia, while animals in the Sham and I/R groups
received the equal volume of physiological saline. At the end of the experiment,
lung, liver, and blood samples were collected and analyzed. RESULTS:
Malondialdehyde levels and histological injury scores were increased, and
superoxide dismutase activities were decreased in the lung and liver tissues in
the I/R group compared with the Sham group (P<0.05). Serum levels of alanine
aminotransferase, aspartate aminotransferase, tumor necrosis factor-?,
interleukin-6, and lung tissue wet weight to dry weight ratio were increased in
the I/R group compared with the Sham group (P<0.05). NF-?B expression in
intestinal tissues was significantly higher in the I/R group than in the Sham
group. These changes were significantly reversed by treatment with PEP-1-HO-1.
CONCLUSIONS: This study demonstrates that administration of PEP-1-HO-1 has a
protective role against lung and liver injury after intestinal I/R, attributable
to the reduction of released proinflammatory cytokines regulated by NF-?B.
