Biliverdin inhibits activation of NF‐κB: Reversal of inhibition by human biliverdin reductase [PDF]
International Journal of Cancer, 2007 AbstracthBVR functions in the cell as a reductase and as a kinase. In the first capacity, it reduces biliverdin, the product of HO activity, to the effective intracellular antioxidant, bilirubin; as a dual‐specificity kinase (S/T/Y) it activates the MAPK and IGF/IRK receptor signal transduction pathways. NF‐κB and the MAPK pathway are activated by ROS,

Eggshell Biliverdin as an Antioxidant Maternal Effect [PDF]
BioEssays, 2020 AbstractIn this essay, the hypothesis that biliverdin pigment plays an antioxidant role in the avian eggshell is proposed. Due to its ability to scavenge free radical species and to reduce mutation, biliverdin potentially counteracts the oxidative action of pathogens that penetrate the eggshell and/or protects the shell membrane from oxidation, thus ...

Study of thiol addition to biliverdine, the synthesis of labelled bilirubine [PDF]
, 2011 Biliverdin and bilirubin are bile pigments which are degradation products of heme. Biliverdin (BV) is greenish-blue pigment and is reduction product of tetrapyrrolic core of heme by influence of the hemoxygenase (HO).

Direct Antioxidant Properties of Bilirubin and Biliverdin. Is there a Role for Biliverdin Reductase? [PDF]
Frontiers in Pharmacology, 2012 Reactive oxygen species (ROS) and signaling events are involved in the pathogenesis of endothelial dysfunction and represent a major contribution to vascular regulation. Molecular signaling is highly dependent on ROS. But depending on the amount of ROS production it might have toxic or protective effects.

Study of fluorescent labelled bilirubine preparation [PDF]
, 2013 Heme is a prosthetic group containing iron atom at the center of the tetrapyrrole cycle, which is the part of hemoglobin. Heme is metabolized by heme oxygenase to linear tetrapyrrolic pigment - biliverdine.

Biliverdin as a Pigment in a Fish [PDF]
Nature, 1945 IN Belone belone, the garfish, the bones, scales and fin rays are of a bright green colour. The chemical nature of this well-known colouring matter has long remained unknown. It cannot be extracted from the tissues in which it occurs by any organic, or neutral, weak acid or alkaline inorganic solvent.
