[Effect of 2 inhibitors of glycoprotein synthesis, tunicamycin and 2-deoxyglucose, on development of the sea urchin (Paracentrotus lividus) egg].

Tunicamycin, an inhibitor of glycoprotein synthesis, inhibits the development of the sea Urchin egg. Gastrulation is very sensitive to the Tunicamycin. Fertilization is not inhibited. 2-deoxy-D-glucose inhibits gastrulation and induces the hyperdevelopment of ectodermic structures.
