Increasing attention has been paid to the effects of hypoxia, heavy metals and heat shocks on gene expression and to the similarities in their actions. This paper compares mRNA levels of two putative hypoxia, heavy metal and heat shock sensitive genes: heme oxygenase-1 (HO-1) and vascular
Hemin inhibits cyclin D1 and IGF-1 expression via STAT5b under hypoxia in ERalpha-negative MDA-MB 231 breast cancer cells.

Cyclin D1 and insulin-like growth factor 1 receptor (IGF-1R) are key regulators of cell proliferation that are overexpressed in most breast cancers. The purpose of the present study was to investigate the molecular mechanism by which hemin exerts its inhibitory effects on aggressive breast cancer

Ischemia/Reperfusion injury and hemolysis are characterized by erythrocyte lysis and release of free heme into the microcirculation. Following substantial erythrocyte lysis, heme overwhelms circulatory heme-binding protein networks rapidly forming hemin, the oxidized form of iron protoporphyrin IX.

BACKGROUND
One effect of solid tumors is severe hypoxia of local tissues. Heme oxygenase-1 (HO-1) is highly expressed in a variety of human tumor tissues; its induction and activity are closely related to growth of solid tumors. Hypoxia inducible factor-1 (HIF-1) is a transcription factor that

OBJECTIVE
To investigate the effect of chronic intermittent hypoxia (CIH) on inflammatory and pathological changes of the lung in an animal model as well as the protective effect of heme oxygenase-1 in this process.
METHODS
Twenty-four Male Sprague-Dawley rats were randomly divided into 4 groups:

OBJECTIVE
To explore changes of expression of heme oxygenase (HO) and production of endogenous carbon monoxide in hypoxic pulmonary artery smooth muscle cells (PASMCs) of rats and study their effects on type I collagen under hypoxia.
METHODS
PASMCs of rats were cultured in vitro and incubated under

Heme oxygenase-1 (HO-1) catalyzes the enzymatic degradation of heme to carbon monoxide, bilirubin, and iron. All three products possess biological functions; bilirubin, in particular, is a potent free radical scavenger of which its antioxidant property is enhanced at low oxygen tension. Here, we

OBJECTIVE
MTT colorimetric assay, in situ hybridization and immunocytochemistry were performed to investigate the effect of endogenous and exogenous CO on the proliferation of PASMCs and the expression of PDGF-B and protooncogene bcl-2, P53 (mutant type) in PASMCs, in order to elucidate the

OBJECTIVE
To investigate the expression of inducible heme oxygenase (HO-1) gene in pulmonary artery smooth muscle cells (PASMCs) exposed to hypoxia, and the influence of carbon monoxide (CO) on the proliferation of PASMCs under hypoxic conditions.
METHODS
Primary culture of rat PASMCs were passed
Prevention of halothane-induced hepatotoxicity by hemin pretreatment: protective role of heme oxygenase-1 induction.

Reductive metabolism of halothane in phenobarbital-pretreated rats is known to increase free radical formation that results in hepatotoxicity. It also is associated with a marked induction of microsomal heme oxygenase-1 (HO-1), suggesting that there is an alteration in heme metabolism. In this

Hypoxia and growth factor stimulation induce hypoxia-inducible factor-1α (HIF-1α), conferring upon cancer cells the ability to adapt to microenvironments and enhance proliferation, angiogenesis and metastasis. Hemin, an iron-binding porphyrin, has been used to treat porphyria attacks, particularly

Hypoxia is a hallmark of many malignant solid tumors. The inadequate oxygen concentration in the hypoxic regions of a solid tumor impedes the efficiency of photodynamic therapy (PDT) because the generation of reactive oxygen species during the PDT process is directly dependent on the available

Induction of heme oxygenase-1 (HO-1) in renal tubules occurs as an adaptive and beneficial response in acute renal failure (ARF) following ischemia and nephrotoxins. Using an in vitro model of polarized Madin-Darby canine kidney (MDCK) epithelial cells, we examined apical and basolateral cell

Erythropoietin (EPO) and iron are both indispensable hematopoietic factors and are often studied in humans and rodents. Iron activates prolyl hydroxylases (PHDs) and promotes the degradation of the α-subunit of hypoxia inducible factor (HIF), which regulates EPO production. Iron also causes

Both iron and the major iron-binding protein ferritin are enriched in oligodendrocytes compared with astrocytes and neurons, but their functional role remains to be determined. Progressive hypoxia dramatically induces the synthesis of ferritin in both neonatal rat oligodendrocytes and a human
