Ascorbic acid partly antagonizes resveratrol mediated heme oxygenase-1 but not paraoxonase-1 induction in cultured hepatocytes - role of the redox-regulated transcription factor Nrf2

BMC Complementary and Alternative Medicine, 2011
Background Both resveratrol and vitamin C (ascorbic acid) are frequently used in complementary and alternative medicine. However, little is known about the underlying mechanisms for potential health benefits of resveratrol and its interactions with ...

Impairment of neutrophil oxidative burst in children with sickle cell disease is associated with heme oxygenase-1

Haematologica, 2015
Sickle cell disease is a risk factor for invasive bacterial infections, and splenic dysfunction is believed to be the main underlying cause. We have previously shown that the liberation of heme in acute hemolysis can induce heme oxygenase-1 during ...

Heme-oxygenases during erythropoiesis in K562 and human bone marrow cells. [PDF]

PLoS ONE, 2011
In mammalian cells, heme can be degraded by heme-oxygenases (HO). Heme-oxygenase 1 (HO-1) is known to be the heme inducible isoform, whereas heme-oxygenase 2 (HO-2) is the constitutive enzyme.

Heme oxygenase-1 deletion affects stress erythropoiesis. [PDF]

PLoS ONE, 2011
BACKGROUND:Homeostatic erythropoiesis leads to the formation of mature red blood cells under non-stress conditions, and the production of new erythrocytes occurs as the need arises.

Regulation of Complement Activation by Heme Oxygenase-1 (HO-1) in Kidney Injury

Antioxidants, 2021
Heme oxygenase is a cytoprotective enzyme with strong antioxidant and anti-apoptotic properties. Its cytoprotective role is mainly attributed to its enzymatic activity, which involves the degradation of heme to biliverdin with simultaneous release of ...

Heme catabolism by heme oxygenase-1 confers host resistance to Mycobacterium infection [PDF]

, 2013
Heme oxygenases (HO) catalyze the rate-limiting step of heme degradation. The cytoprotective action of the inducible HO-1 isoform, encoded by the Hmox1 gene, is required for host protection against systemic infections. Here we report that upregulation of

Carbon monoxide: from toxin to endogenous modulator of cardiovascular functions

Brazilian Journal of Medical and Biological Research, 1999
Carbon monoxide (CO) is a pollutant commonly recognized for its toxicological attributes, including CNS and cardiovascular effects. But CO is also formed endogenously in mammalian tissues. Endogenously formed CO normally arises from heme degradation in a

Human AKI and Heme Oxygenase-1 [PDF]

Journal of the American Society of Nephrology, 2012
Findings derived from animal models of AKI gain clinical credence and appeal when translational studies corroborate their occurrence in human AKI. In the current issue of JASN , Zager et al.

Heme Oxygenase-1 [PDF]

Circulation, 2006
Schmid and coworkers1 were the first to report on the presence of heme oxygenase (HO) in liver microsomes capable of degrading heme to bilirubin, and this activity was subsequently dissociated from cytochrome P-450.2,3 HO catalyzes the first and rate-limiting step in the oxidative degradation of heme (Fe-protoporphyrin-IX) to carbon monoxide (CO ...

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

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