5-azacytidine (5-azaCR), an analogue of cytidine, inhibits nuclear DNA methylation in early sea urchin embryos. This inhibition is specific and dose-dependent. Exposure of sea urchin embryos at any stage between one-cell and blastula, to micromolar quantities of 5-azaCR invariably inhibits development beyond the blastula stage. In a substantial number of(More)
