The intracellular levels of GSH, GSSG, and protein-glutathione disulfide (protein-SSG) have been measured in the eggs and developing embryos of the sea urchins Lytechinus pictus and Stronglyocentrotus purpuratus. Total cellular glutathione is maintained in a very highly reduced state during these initial stages of development. Thus for unfertilized eggs of L. pictus the results (mumol/g dry weight) were 11 +/- 1 for GSH, 0.02 +/- 0.01 for GSSG, and 0.07 +/- 0.02 for protein-SSG. No significant change in these values was observed upon fertilization of the eggs or during the first cell division cycle. The values obtained with S. purpuratus were somewhat greater, but were also found to exhibit no significant variations upon fertilization or cell division. These observations indicate that changes in the total cellular glutathione thiol-disulfide status are not involved in the control mechanisms which operate during fertilization of the first cell division cycle in the sea urchin egg.
