The Relevance of Mammalian Peroxiredoxins to the Gametogenesis, Embryogenesis, and Pregnancy Outcomes

Abstract

Peroxiredoxin (PRX) defines a family that provides antioxidant defense in different cell types by removing reactive oxygen species (ROS) through conserved active cysteines, with the support of other types of antioxidants such as thioredoxin, glutaredoxin, and glutathione peroxidase. By regulation of intracellular ROS levels, the mammalian PRXs influence a variety of reproductive processes including gamete maturation, fertilization, and embryo development. Experimental mice lacking PRXs developed normally, but …
