The effect of increasing cytoplasmic calcium on cyclic adenosine monophosphate (cAMP)‐
dependent meiotic arrest (% GV where GV is germinal vesicle) in hamster oocytes was …

We report the results of experiments which support the hypothesis that, in mouse oocytes, a
decrease in intraoocyte cyclic AMP (cAMP) initiates meiotic maturation; oocytes …

This study investigated further our previous finding that testosterone synergizes with
dibutyryl cyclic AMP (dbcAMP) to arrest the meiosis of a very high proportion of cumulus …

The second messenger cAMP has been implicated in the regulation of mammalian and
amphibian oocyte maturation. Although a decrease in intraoocyte levels of cAMP precedes …

Intracellular concentrations of cyclic AMP (cAMP) were measured in pig oocytes maturing in
vivo or in vitro. Maturation in vivo was induced with 500 iu hCG administered to gilts treated …

The present study was undertaken to assess the role of alterations of intraoocyte cAMP
concentrations in the meiotic maturation of isolated and follicle-enclosed oocytes. In isolated …

The germinal vesicle (GV) of follicle-enclosed oocytes in mammals remains arrested at the
dictyate state of meiosis. Upon releasing the oocytes from the follicles, the meiotic process …

Abstract Considerable evidence implicates cyclic 3′, 5′ adenosine monophosphate
(AMP) in the maintenance of meiotic arrest of mammalian oocytes. Since this laboratory …

Mammalian oocytes are arrested in meiotic prophase by an inhibitory signal from the
surrounding somatic cells in the ovarian follicle. In response to luteinizing hormone (LH) …

The regulation of final oocyte maturation has been the topic of fundamental research for
several decades. Understanding of the complex signalling mechanism between the somatic …
