Postexposure administration of
hemopexin, a heme-scavenging protein, decreased lung injury and improved survival.[52] Studies also demonstrated that humanized transgenic mice overexpressing HO-1 were significantly protected from exposure to Br[sub]2.[52] These are the first studies delineating the pathogenesis of Br[sub]2 toxicity in respiratory diseases and demonstrated the critical role of heme in ARDS caused by Br[sub]2[Figure 3].
Based on a multipe sequence alignment with representative orthologues from other fish species and human
hemopexin, the CcWap65 polypeptide shares varying degrees of homology with their corresponding orthologues (Fig.
