## Abstract Mouse oocytes arrested in dictyate of the first meiotic prophase by dibutyryl cyclic AMP accumulated exogenous valine at the same rate as oocytes undergoing meiotic maturation. The apparent rate of protein synthesis and the spectrum of proteins synthesized were not significantly affecte
## Abstract Cytogenetic data are presented which indicate species differences in the response of oocytes maturing in vitro in the presence of dibutyryl cyclic AMP (dbcAMP). Inhibition of ewe oocyte maturation was noted at germinal vesicle, MI, and MII in the presence of 25–750 μg/ml of dbcAMP. Cow
## Abstract The inhibitory effect of dithiothreitol on meiotic maturation of mouse oocytes in vitro is a function of the intracellular dibutyryl cyclic AMP concentration. Inhibition of nuclear (germinal vesicle) breakdown by dibutyryl cyclic AMP is reversed upon transfer of oocytes to plain culture
