We have reported that in vitro treatment with follicle-stimulating hormone (FSH) delays by
about 3 h spontaneous meiotic resumption in cumulus cell-enclosed mouse oocytes. In the …

Cyclic AMP (cAMP) is a second messenger that plays a critical role in follicular recruitment,
development and luteinization in the mammalian ovary. The cellular level of cAMP is largely …

The effects of follicle-stimulating hormone (FSH) and cyclic guanosine 3′, 5′-
monophosphate (cGMP) on spontaneous oocyte maturation and cyclic adenosine 3′, 5 …

The effects of the putative maturation inhibitor in porcine follicular fluid on
gonadotropinstimulated reversal of cyclic adenosine monophosphate (cAMP)‐maintained …

The effect of adenylate cyclase stimulation via the components of the enzyme on nuclear
maturation in bovine cumulus-enclosed and zona-free oocytes was examined. The …

The present study was designed to address the physiological role played by cAMP on gap
junction (GJ) mediated communications between oocyte and cumulus cells during in vitro …

Fully-grown mammalian oocytes within healthy preovulatory follicles are arrested in the first
meiotic prophase until the gonadotropins surge in vivo. However, the means by which …

Oocyte cumulus complexes (OCC) were isolated from antral follicles of proestrous hamsters
prior to the luteinizing hormone (LH)/follicle-stimulating hormone (FSH) surge and then …

This study was undertaken to analyse the time relationships between breakdown of
communication in the cumulus-oocyte complex and reinitiation of meiosis in the oocyte. In …

Recent work on the mouse is discussed. The results support the view that cAMP participates
in the maintenance of meiotic arrest, and that purines may help sustain meiosis-arresting …
