## Abstract Sea urchin embryos of the species Paracentrotus lividus were treated continuously with different concentrations of all‐trans retinoic acid (RA) or dimethylsulfoxide (DMSO) at different developmental stages. A delay in embryonic development was observed when embryos were cultured in the

We have reinvestigated the existence of cyclical fluctuations of protein synthesis and have examined the effects of reducing it in early embryos of the purple sea urchin, Strongylocentrotus purpuratus. The results show that protein synthesis increases linearly during the first 45-60 minutes after fe

## Abstract Natural derivatives of indole‐3‐carbaldehyde were isolated from the tropical marine ascidian __Stomoza murrayi.__ A series of 13 derivatives, three natural and 10 synthetic (brominated and N‐methylated), were examined for their effects on cell division of sea urchin eggs. These derivati

## Abstract Exposure of early sea urchin embryos to 5‐bromodeoxyuridine (at concentrations up to 100 μg per ml) severely decreases the uptake of exogenous ^3^H‐uridine into RNA. However, the actual gross rate of DNA or RNA synthesis in these embryos appears not to be affected by the presence of 5‐b
