Heme oxygenase substrates acutely lower blood pressure in hypertensive rats

open access: yes, 1996
Heme oxygenase catalyzes the metabolism of heme to biliverdine, free iron, and carbon monoxide. The current study was designed to determine if treatment with the heme oxygenase substrates heme-L-arginate or heme-L-lysinate, to stimulate formation of ...

Intermolecular Carbon–Carbon Naphthalene Coupling Involves a Radical Mechanism Driven by Cytochrome P450 in Alternaria alternata

open access: yesAngewandte Chemie, EarlyView.
1,8‐DHN is an important intermediate to form complex aromatic ring systems. Phenol‐coupling reactions are important for the dimerization of two molecules. Here, we show that a fungal cytochrome P450 enzyme catalyzes specific C─C bonds. ABSTRACT Dihydroxynaphthalene (DHN) derivatives are precursors of biologically important molecules, including melanin ...

Metformin alleviates spinal cord injury by inhibiting nerve cell ferroptosis through upregulation of heme oxygenase-1 expression

open access: yesNeural Regeneration Research
[INLINE:1] Previous studies have reported upregulation of heme oxygenase-1 in different central nervous system injury models. Heme oxygenase-1 plays a critical anti-inflammatory role and is essential for regulating cellular redox homeostasis.

Recent insights into the molecular mechanism of ubiquinol oxidation by cytochrome bc1

open access: yesFEBS Open Bio, EarlyView.
The review reflects on the mechanism of the catalytic reaction in cytochrome bc1: the electron bifurcation that involves the separation of two electrons derived from the quinol oxidation to opposite sides of the enzyme across the membrane. This review summarizes the long‐standing effort to understand the mechanism of quinol oxidation catalyzed by ...

Strontium Ranelate Elevates Expression of Heme Oxygenase-1 and Decreases Alveolar Bone Loss in Rats

open access: yeseJournal of Oral Maxillofacial Research, 2018
Objectives: The purpose of this study was to determine the effects of strontium ranelate on ligature-induced periodontitis in rats and assess the putative involvement of heme oxygenase-1 (HO-1) pathway in these effects.

Selective elimination of quiescent cancer cells by dequalinium chloride via ROS‐mediated ferroptosis

open access: yesFEBS Open Bio, EarlyView.
Dequalinium chloride (DQ) selectively eliminates quiescent cancer cells (QCCs) by amplifying mitochondrial ROS. QCCs exhibit elevated basal ROS and limited redox‐buffering capacity, making them vulnerable to further ROS increases. DQ‐induced ROS exceeds the tolerance threshold, triggering lipid peroxidation and ferroptosis, whereas proliferating cells ...

Heme-Oxygenase and Kidney Transplantation: A Potential for Target Therapy?

open access: yesBiomolecules, 2020
Kidney transplantation is a well-established therapy for patients with end-stage renal disease. While a significant improvement of short-term results has been achieved in the short-term, similar results were not reported in the long-term. Heme-oxygenase (

Regulation of haem oxygenase-1 nitrosative stress in cardiac cells. [PDF]

open access: yes, 2005
The reactive nitrogen species (RNS) nitric oxide (NO), nitroxyl anion (NO") and nitrosonium cation (NO+), modulate a myriad of biological processes. The microsomal haem oxygenases (HO-1, HO-2 and HO-3) oxidatively catabolise haem to bilirubin, carbon ...

Ferritin heavy chain mediates the protective effect of heme oxygenase-1 against oxidative stress

open access: yes, 2017
The phenomenon that heme oxygenase-1 (HO-1) protects cell from injury yet its enzymatic product, iron, may facilitate generation of free radical has been long puzzling. Here we establish a functional connection between ferritin heavy chain (FHC) and HO-1.
