Immune-Related Functions of Heme Oxygenase-1

Antioxidants, 2023
Heme oxygenase (HO)-1 is a well-known cytoprotective enzyme due to its enzymatic action, which involves the catalysis of heme into anti-apoptotic and antioxidant molecules such as bilirubin, biliverdin and CO [...]

Heme Catabolism and Heme Oxygenase in Neurodegenerative Disease

Antioxidants & Redox Signaling, 2004
Heme oxygenase, the rate-limiting step in heme catabolism, appears to play an important role in a number of neurodegenerative disorders, such as Alzheimer disease. Interestingly, the spatial distribution of heme oxygenase-1 expression in diseased brain is essentially identical to that of the pathological expression of tau, suggesting a key role for ...

Evidence for Heme Oxygenase Activity in a Heme Peroxidase

Biochemistry, 2009
The heme peroxidase and heme oxygenase enzymes share a common heme prosthetic group but catalyze fundamentally different reactions, the first being H(2)O(2)-dependent oxidation of substrate using an oxidized Compound I intermediate, and the second O(2)-dependent degradation of heme.

Heme oxygenase 1 overexpression increases iron fluxes in Caco-2 cells [PDF]

Biological Research, 2006
Heme oxygenase-1 is a microsomal enzyme that, when induced by stress, protects the cells from oxidative injury. Heme oxygenase-1 participates in the cleavage of the heme ring producing biliverdin, CO and ferrous Fe.

Heme oxygenase-like dimetal oxidases and oxygenases. [PDF]

Biochem Soc Trans
Abstract The first heme oxygenase-like dimetal oxidase/oxygenase (HDO) was functionally validated through coordinated spectroscopic and rapid kinetic studies of the fatty acid decarboxylase UndA. The enzyme superfamily has since been recognized to orchestrate a variety of substrate transformations for natural product biosynthesis.

Heme Oxygenase-Like Metalloenzymes. [PDF]

Annu Rev Biochem
Heme oxygenase (HO)-like metalloenzymes are an emerging protein superfamily diverse in reaction outcome and mechanism. Found primarily in bacterial biosynthetic pathways, members conserve a flexible protein scaffold shared with the heme catabolic enzyme, HO, and a set of metal-binding residues.

Heme and immunity: The heme oxygenase dichotomy. [PDF]

J Inorg Biochem
Heme, an iron containing organic ring, is required for a diverse range of biological processes across all forms of life. Although this nutrient is essential, its pro-inflammatory and cytotoxic properties can lead to cellular damage. Heme oxygenase 1 (HO-1) is an endoplasmic reticulum (ER)-anchored enzyme that degrades heme, releasing equimolar amounts ...

Genetic variants of the promoter of the heme oxygenase-1 gene and their influence on cardiovascular disease (The Ludwigshafen risk and cardiovascular health study) [PDF]

, 2009
Background Heme oxygenase-1 is an inducible cytoprotective enzyme which handles oxidative stress by generating anti-oxidant bilirubin and vasodilating carbon monoxide.

Pathological significance of heme oxygenase-1 as a potential tumor promoter in heme-induced colorectal carcinogenesis [PDF]

, 2023
The significance of the heme-metabolizing enzyme heme oxygenase-1 (HMOX1) in the pathogenesis of colorectal cancer (CRC) has not been fully explored. HMOX1 cytoprotection is imperative to limit oxidative stress.

HMOX1 gene promoter alleles and high HO-1 levels are associated with severe malaria in Gambian children. [PDF]

, 2012
Heme oxygenase 1 (HO-1) is an essential enzyme induced by heme and multiple stimuli associated with critical illness. In humans, polymorphisms in the HMOX1 gene promoter may influence the magnitude of HO-1 expression.
