Heme oxygenase-1 increases endothelial progenitor cells.
OBJECTIVE Induction of heme oxygenase-1 (HO-1) protects against atherosclerotic disease in part by promoting reendothelialization. As endothelial progenitor cells (EPCs) contribute to reendothelialization, we examined the role of HO-1 on bone marrow and circulating EPCs. METHODS AND RESULTS In a rabbit model of aortic balloon injury, pharmacological induction of HO-1 enhanced reendothelializa...
متن کاملThe 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 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 کاملThe Status of Nitric Oxide and its Backup, Heme Oxygenase 1, in Thromboangiitis Obliterans
Background: Until recently, a gene polymorphism in the promoter region of endothelial nitric oxide synthase has been suggested as a risk factor for thromboangiitis obliterans (TAO) development. The aim of this study was to compare the metabolites of nitric oxide (NO) and its backup, heme-oxygenase-1 (HMOX1), between TAO patients and those of a smoking control group matched by race, age, sex, an...
متن کاملHow Heme Oxygenase-1 Prevents Heme-Induced Cell Death
Earlier observations indicate that free heme is selectively toxic to cells lacking heme oxygenase-1 (HO-1) but how this enzyme prevents heme toxicity remains unexplained. Here, using A549 (human lung cancer) and immortalized human bronchial epithelial cells incubated with exogenous heme, we find knock-down of HO-1 using siRNA does promote the accumulation of cell-associated heme and heme-induce...
