The Expression of Heme Oxygenase-1 in Human-Derived Cancer Cell Lines
Background: Heme oxygenase-1 (HO-1) is a cytoprotective and antiapoptotic enzyme, which has been involved in maintaining cellular homeostasis, and plays an important protective role by modulating oxidative injury. Up-regulation of (HO-1) has contributed to tumorogenicity of some cancers. In this study we investigated the expression pattern of the HO-1, in five different human-derived cancer cel...
متن کاملThioredoxin facilitates the induction of heme oxygenase-1 in response to inflammatory mediators.
Heme oxygenase (HO)-1 is a stress response protein that is regulated by oxidative stress. HO-1 catalyzes the generation of biliverdin, carbon monoxide, and iron from heme. Lipopolysaccharide (LPS) and interleukin (IL)-1beta induce HO-1 through the binding of nuclear proteins to AP-1 motifs in enhancer regions upstream from the transcription start site. The DNA binding activity of AP-1 proteins ...
متن کاملInduction of Heme Oxygenase -1 By Lipocalin 2 Mediated By Nf-Kb Transcription Factor
Purpose: Effect of lipocalin 2 on the expression of heme oxygenase I , II and NF-kB transcription factor was the purpose of this survey. Materials and Methods: Lcn2 was cloned to pcDNA3.1 plasmid by using genetic engineering method. The recombinant vector was transfected to CHO and HEK293T to establish stable cell expressing lipocalin 2. The presence of lipocalin 2 gene in these cells was confi...

متن کاملHeme Oxygenase-1: Its Therapeutic Roles in Inflammatory Diseases
Heme oxygenase (HO)-1 is an inducible enzyme that catalyzes the first and rate-limiting step in the oxidative degradation of free heme into ferrous iron, carbon monoxide (CO), and biliverdin (BV), the latter being subsequently converted into bilirubin (BR). HO-1, once expressed during inflammation, forms high concentrations of its enzymatic by-products that can influence various biological even...
