Título: | Eggshell Biliverdin as an Antioxidant Maternal Effect: Biliverdin as an Antioxidant Resource in Oviparous Animals |

Fecha de publicación: | ago-2020 | Editor: | John Wiley & Sons | Citación: | BioEssays 42(8): 2000010 (2020) | Resumen: | In 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 promoting the proven antioxidant and antimicrobial capacities of the shell membrane itself. Additionally, biliverdin may be able to inhibit viral replication in the eggshell due to its ascribed antiviral properties. Moreover, previous results in other taxa leave open the question of whether biliverdin can be absorbed by the embryo from the eggshell and play a role in embryogenesis. These mechanisms of antioxidant action of eggshell biliverdin remain totally unexplored in birds and in other oviparous animals. The main assumptions and predictions of the antioxidant hypothesis are developed, and directions for future research are proposed. | Versión del editor: | http://dx.doi.org/10.1002/bies.202000010 | URI: | http://hdl.handle.net/10261/237301 | DOI: | 10.1002/bies.202000010 | Identificadores: | doi: 10.1002/bies.202000010 issn: 1521-1878 |
