Metalloporphyrins inactivate caspase-3 and -8 [PDF]
, 2005 Activation of caspases represents one of the earliest biochemical indicators for apoptotic cell death. Therefore, measurement of caspase activity is a widely used and generally accepted method to determine apoptosis in a wide range of in vivo and in ...

Palmitoylation of Metazoan Carotenoid Oxygenases [PDF]
Molecules, 2020 Abundant in nature, carotenoids are a class of fat-soluble pigments with a polyene tetraterpenoid structure. They possess antioxidant properties and their consumption leads to certain health benefits in humans. Carotenoid cleavage oxygenases (CCOs) are a superfamily of enzymes which oxidatively cleave carotenoids and they are present in all kingdoms of

A Dual Role of Heme Oxygenase-1 in Cancer Cells
International Journal of Molecular Sciences, 2018 Heme oxygenase (HO)-1 is known to metabolize heme into biliverdin/bilirubin, carbon monoxide, and ferrous iron, and it has been suggested to demonstrate cytoprotective effects against various stress-related conditions.

When is a target not a target?
eLife, 2019 Cells rely on prolyl hydroxylase enzymes to sense low levels of oxygen, but they might act on fewer targets than previously thought.

Alternative 5' untranslated regions are involved in expression regulation of human heme oxygenase-1. [PDF]
PLoS ONE, 2013 The single nucleotide polymorphism rs2071746 and a (GT)n microsatellite within the human gene encoding heme oxygenase-1 (HMOX1) are associated with incidence or outcome in a variety of diseases.

Heme oxygenase-1 mitigates ferroptosis in renal proximal tubule cells.
AJP - Renal Physiology, 2018 Ferroptosis is an iron-dependent form of regulated nonapoptotic cell death, which contributes to damage in models of acute kidney injury (AKI). Heme oxygenase-1 (HO-1) is a cytoprotective enzyme induced in response to cellular stress, and is protective ...

Exploring the oxygenase function of Form II Rubisco for production of glycolate from CO2
AMB Express, 2021 The oxygenase activity of Ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco) converts ribulose-1,5-bisphosphate (RuBP) into 2-phosphoglycolate, which in turn channels into photorespiration, resulting in carbon and energy loss in higher plants.

Development of NASH in Obese Mice is Confounded by Adipose Tissue Increase in Inflammatory NOV and Oxidative Stress [PDF]
, 2018 Aim. Nonalcoholic steatohepatitis (NASH) is the consequence of insulin resistance, fatty acid accumulation, oxidative stress, and lipotoxicity.We hypothesize that an increase in the inflammatory adipokine NOV decreases antioxidant Heme Oxygenase 1 (HO- 1)

The specificity of cysteamine oxygenase
FEBS Letters, 1975 Oxidation of cysteamine to hypotaurine is catalyzed by cysteamine oxygenase (EC 1.13.11.19), a non-heme iron enzyme of large distribution [l-3] . A similar oxidation of cysteine to cysteine sulfinic acid has been reported to require a different oxygenase [4,.5]. Specificity of cysteamine oxygenase has been studied earlier in this laboratory by assaying
