The effect of cytochalasin D on protein synthesis in Xenopus laevis oocytes.

De Sousa PA , Masui Y .


???displayArticle.abstract???
Defolliculated fully grown oocytes of Xenopus laevis were treated with cytochalasin D (10 micrograms/ml) and their protein synthesis was studied by labelling with S-35 methionine. This treatment brought about an alteration in pigment pattern as well as a reduction in amino acid uptake by the oocytes. However, the radioactive amino acid taken by cytochalasin-treated oocytes was incorporated into protein in the same proportion as in untreated oocytes. These results suggested that subcortical pigment distribution and amino acid uptake in fully grown oocytes were microfilament-dependent processes, whereas protein synthesis in the oocyte was not.
