Differential regulation of oocyte maturation and cumulus expansion in the mouse oocyte-cumulus cell complex by site-selective analogs of cyclic adenosine monophosphate

Article Abstract:

Analogs of cyclic adenosine 5'-monophosphate (cAMP) were tested in paired combinations with type I or type II protein kinase isozymes A (PKA) found within the mouse oocyte-cumulus cell complex to determine whether cAMP-dependent protein kinase isozymes influence the response of the complex to cAMP. The potency of the isozymes were characterized according to their ability to prevent germinal vesicle breakdown and to cumulus expansion in response to PKA stimulation.
