Abstract
Plasminogen activator, tissue type (PLAT) and its inhibitor serpin family E member 1 (SERPINE1) cooperatively regulate PLAT activity in various reproductive processes. However, it is unknown whether this includes bovine oocyte maturation. We addressed this question in the present study by evaluating PLAT and SERPINE1 protein localization in immature cumulus-oocyte complexes (COCs), as well as PLAT mRNA and protein expression in cultured COCs after 0, 8, 16, and 24 h of in vitro maturation (IVM). We also examined the effects of PLAT and SERPINE1 on germinal vesicle breakdown (GVBD) and oocyte cyclic 3' 5' adenosine monophosphate (cAMP) levels, cumulus expansion index, and expansion-related gene expression in oocytes derived from bovine COCs cultured for 4, 8, and 12 h and in COCs cultured for 16 h. Both PLAT and SERPINE1 localized in cumulus cells but only the latter was detected in oocytes. PLAT and SERPINE1 transcript levels increased during IVM; however, from 8 to 16 h, the levels of PLAT remained stable whereas those of SERPINE1 increased, resulting in a decline in PLAT concentration. Additionally, PLAT delayed GVBD, increased oocyte cAMP levels, and blocked cumulus expansion and associated gene expression, which was reversed by SERPINE1 supplemented. Thus, PLAT delays bovine oocyte GVBD by enhancing oocyte cAMP levels during the first 8 h of IVM; suppression of PLAT activity via accumulation of SERPINE1 in COCs results in cumulus expansion from 8 to 16 h of IVM. These findings provide novel insights into the molecular mechanisms underlying in vitro bovine oocyte maturation.

Abstract
The serpin peptidase inhibitor, clade E, member 2 (SERPINE2) inhibits urokinase-type plasminogen activator (PLAU) and tissue-type plasminogen activator. Higher SERPINE2 expression levels were detected in cumulus cells of human immature oocytes than in those of mature oocytes. The objective of this study was to evaluate whether high SERPINE2 levels in cumulus cells are associated with oocyte immaturity. Using the mouse cumulus–oocyte complex as an experimental model, the effects of elimination and overexpression of SERPINE2 in cumulus cells on cumulus expansion and oocyte maturation were assayed by in vitro maturation. Serpine2 and PLAU transcripts were the most highly expressed serpins and plasminogen activators, respectively. Their expression was coordinately regulated in cumulus cells during gonadotropin-induced oocyte maturation. Silencing of Serpine2 expression using small interfering RNAs or blockage of SERPINE2 protein using a specific antibody had no effect on oocyte maturation. However, overexpression of Serpine2 or exogenous supplementation with high levels of SERPINE2 impaired cumulus expansion and oocyte maturation, probably by decreasing hyaluronan synthase 2 (Has2) and versican (Vcan) mRNA expression. Amiloride, a specific PLAU inhibitor, also suppressed these processes. PLAU supplementation of the oocyte in vitro maturation medium caused earlier and more extensive expansion of cumulus cells and oocyte maturation that may be mediated by increased Has2 mRNA expression. However, these effects were neutralized by coincubation with SERPINE2 or amiloride and PLAU. In conclusion, SERPINE2 and PLAU are involved in cumulus expansion and oocyte maturation. High SERPINE2 levels impair these processes, probably by decreasing cumulus matrix gene expression as well as reducing cumulus hyaluronan contents and inhibiting PLAU activity. These findings may explain why cumulus cells surrounding immature human oocytes express high SERPINE2 levels.

Abstract
By using DNA 3'-end labeling, immunocytochemistry and mRNA in situ hybridization detection techniques, the expression of inhibin subunits and LH receptor in the granulosa cells and tissue-type plasminogen activator (tPA) in the oocytes has been studied in relation to follicular development and atresia. The results demonstrated that: (i) tPA activity in the oocytes of normal developing follicles is undetectable, and increases significantly in the follicle undergoing atresia; (ii) the production of inhibin subunits in granulosa cells is negatively correlated with the expression of oocyte tPA activity, indicating that they may be an important regulator of oocyte tPA production and follicular development; (iii) in atretic follicles, granulosa cells do not express LH receptor and inhibin subunits. It is therefore suggested that tPA may play a role in oocyte self-destruction and clearance in some of atretic follicles, and inhibin of granulosa-origin might be an inhibitory factor for the translation of tPA in the oocyte.

Abstract
In this study, we provide evidence that plasminogen activator of tissue-type (t-PA), at least, is present in extracts of bovine oocyte cortical granules, and that its activity varies significantly with the duration of oocyte in vitro maturation. Cortical granules were collected from bovine oocytes by means of micromanipulation, after 0, 12, or 24 h of IVM. Our results show that plasminogen activator activity of cortical granule extracts was significantly higher after 24 h of IVM than after 12 h of IVM or before IVM. This activity was apparently due, at least partly, to tissue-type plasminogen activator as shown immunologically. No evidence was found for the presence of urokinase-type plasminogen activator, plasminogen activator inhibitors or plasmin inhibitors in bovine oocyte cortical granule extracts. Our findings further support the hypothesis that t-PA activity of oocyte origin may have a role in oocyte maturation or fertilization, as well as in post-fertilization events, such as cortical reaction and formation of the zona block to polyspermy.

Abstract
We examined whether plasminogen activators (PAs) are produced by bovine cumulus-oocyte complexes (COCs) during maturation in vitro. The effects of epidermal growth factor (EGF) on production of PAs in oocytes and cumulus cells were also examined. When COCs were cultured for 24 h with 30 ng/ml EGF, three plasminogen-dependent lytic zones (58.5 +/- 3.5 kDa, 79.0 +/- 3.0 kDa, and 113.5 +/- 6.5 kDa) were observed. Addition of amiloride, a competitive inhibitor of urokinase-type PA (uPA), to the zymogram eliminated the activity of the 58.5 +/- 3.5-kDa zone, suggesting that this band is a uPA. However, since the activity of the remaining two bands was not eliminated, it was suggested that the 79.0 +/- 3.0-kDa band is a tissue-type PA (tPA) and the 113.5 +/- 6.5-kDa band is possibly a tPA-PA inhibitor (tPA-PAI) complex. In COCs before culture, however, no activity of PAs was detected. At 6 h of culture, the same level of uPA activity was detected in COCs cultured both in the absence and in the presence of EGF. The uPA activity was increased at 12 h of culture but without further increase at 24 h of culture, with higher activity in the presence than in the absence of EGF. The activity of tPA and tPA-PAI was first detected at 24 h of culture in the absence of EGF. In the presence of EGF, however, some activity of tPA-PAI was detected at 12 h of culture. At 24 h of culture, the activity of all PAs was detected in cumulus cells, but only uPA activity was detected in oocytes, with higher activity in the presence than in the absence of EGF. The uPA activity in oocytes was not detected when they were cultured without cumulus cells in either the presence or absence of EGF, although cumulus expansion was stimulated by EGF, exhibiting a time-course similar to that observed in PA production. These results suggest that uPA, tPA, and tPA-PAI are all produced by bovine COCs, but only uPA by oocytes, during maturation in vitro. However, cumulus cells play an essential role or roles in the production of uPA by oocytes, and EGF enhances the roles of cumulus cells.

Abstract
The plasminogen-activator system provides proteolytic activity in many biological processes. The regulation of plasminogen activation may occur at many levels including the synthesis and secretion of plasminogen activators (PA) and the specific inhibition of PA activity by inhibitors. PA-inhibitor type-1 (PAI-1) is an efficient inhibitor of tissue-type PA (tPA) and urokinase-type PA (uPA) that may therefore be instrumental for the control of plasminogen activation. To investigate if coordinated regulation of PA and PA inhibitors take place in vivo in response to physiological signals, we have examined the regulation of PAI-1 and tPA in the ovary during gonadotropin-induced ovulation. We found that PAI-1, as well as tPA activity and mRNA levels, were coordinately regulated by gonadotropins in a time-dependent and cell-specific manner, such that a surge of PA-activity was obtained just prior to ovulation. Both theca-interstitial and granulosa cells synthesized PAI-1, but their maximal PAI-1 expression occurred at different times during the periovulatory period, ensuring inhibition of proteolytic activity in ovarian extra cellular compartments both before and after ovulation. The coordinated regulation of tPA and PAI-1 in the ovary may fine-tune the peak of PA activity which may be important for the regulation of the ovulatory process.
