Heme Proteins, Heme Oxygenase-1 and Oxidative Stress
Heme is ferrous protoporphyrin-IX that is the prosthetic group of hemoproteins, such as hemoglobin, myoglobin and cytochromes that are of vital importance. In contrast, “free heme”, a protein-unbound heme, that is either just synthesized but yet not incorporated into hemoproteins, or that is released from hemoprotein under oxidative conditions, is highly toxic, since it catalyzes the production...
متن کاملMorin Induces Heme Oxygenase-1 via ERK-Nrf2 Signaling Pathway
BACKGROUND Oxidative stress damages to cells or tissues, however, cellular defense systems including heme oxygenase-1 (HO-1) protects them against oxidative stress. Flavonoid compounds can activate cellular defense mechanisms against oxidative stress and it can reduce cell damages. In the present study, the cytoprotective effects of morin (3,5,7,2',4'-pentahydroxyflavone), in terms of HO-1 enzy...
متن کاملDystrophic muscle improvement in zebrafish via increased heme oxygenase signaling.
Duchenne muscular dystrophy (DMD) is caused by a lack of the dystrophin protein and has no effective treatment at present. Zebrafish provide a powerful in vivo tool for high-throughput therapeutic drug screening for the improvement of muscle phenotypes caused by dystrophin deficiency. Using the dystrophin-deficient zebrafish, sapje, we have screened a total of 2640 compounds with known modes of...
متن کاملA Novel Function of Heme Oxygenase-L in Epidermal Differentiation
panniculitis. Result: The most common clinical manifestation was a depressed patch on upper arm. There was 46oh and l3o/o positivity in the ANA and anti-ds DNA test, respectively. His topatho log ica l ly , a l l spec imens revealed lobu lar panniculitis and the majority of cases presented epidermal atrophy and dermal infiltration. Immunohistochemistry showed a predominance of T lymphocytes. Al...
متن کاملMicrosomal Heme Oxygenase
This study characterizes microsomal heme oxygenase, a previously undescribed enzyme which catalyzes the oxidation of heme at the cr-methene bridge to form biliverdin. This step is then coupled with soluble NADPH-dependent biliverdin reductase to form bilirubin; microsomal heme oxygenase is rate-limiting in this pathway. By all analytical criteria, the product of this reaction is bilirubin. Most...
