Hughes CHK, Inskeep EK, Pate JL. Temporal changes in the corpus luteum during early pregnancy reveal regulation of pathways that enhance steroidogenesis and suppress luteolytic mechanisms†. Biol Reprod 2021; 103:70-84. [PMID: 32285125 DOI: 10.1093/biolre/ioaa047] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/11/2020] [Revised: 04/01/2020] [Accepted: 04/09/2020] [Indexed: 11/14/2022] Open
Abstract
Although rescue of the corpus luteum (CL) is required for pregnancy, luteal function during maternal recognition of pregnancy remains largely unexplored. CL were collected from pregnant cattle on days 14, 17, 20, and 23, to encompass the maternal recognition of pregnancy period. Next-generation sequencing was used to profile mRNA abundance during this time, while tandem mass spectrometry and nanostring technology were used to profile proteins and miRNA, respectively. A total of 1157 mRNA were differentially abundant, while 27 miRNA changed, and 29 proteins tended to change. mRNA that increased were regulators of interferon signaling and DNA repair, while those that decreased were associated with luteolytic processes, such as calcium signaling and matrix metallopeptidase (MMP) signaling, indicating inhibition of these processes. One of these, MMP12, was regulated by prostaglandin F2A in vitro. mRNA that were maximally abundant on day 20 were primarily associated with immune processes. Two of these, C-C motif chemokine ligand 1 and NFKB inhibitor alpha, were regulated by interferon tau in vitro. MiRNA that increased were predicted to inhibit phosphatidylinositol signaling, while those that decreased may be negative regulators of steroidogenesis. One protein that was greater on day 20 than on day 14 was aldehyde dehydrogenase 1 family member A1 (ALDH1A1), which synthesizes retinoic acid. Pharmacological inhibition of this enzyme, or of retinoic acid receptor signaling, led to suppression of progesterone production in vitro. Overall, these data indicate that there are changes in the CL of pregnancy that are important for continued luteal function.

Spatio-temporal expression profile of matrix metalloproteinase (Mmp) modulators Reck and Sparc during the rat ovarian dynamics. Reprod Biol Endocrinol 2018; 16:116.

Abstract
BACKGROUND Matrix metalloproteinases (Mmps) and their tissue inhibitors (Timps) are widely recognized as crucial factors for extracellular matrix remodeling in the ovary and are involved in follicular growth, ovulation, luteinization, and luteolysis during the estrous cycle. Recently, several genes have been associated to the modulation of Mmps activity, including Basigin (Bsg), which induces the expression of Mmps in rat ovaries; Sparc, a TGF-β modulator that is related to increased expression of Mmps in cancer; and Reck, which is associated with Mmps inhibition. However, the expression pattern of Mmp modulators in ovary dynamics is still largely uncharacterized. METHODS To characterize the expression pattern of Mmps network members in ovary dynamics, we analyzed the spatio-temporal expression pattern of Reck and Sparc, as well as of Mmp2, Mmp9 and Mmp14 proteins, by immunohistochemistry (IHC), in pre-pubertal rat ovaries obtained from an artificial cycle induced by eCG/hCG, in the different phases of the hormone-induced estrous cycle. We also determined the gene expression profiles of Mmps (2, 9, 13 14), Timps (1, 2, 3), Sparc, Bsg, and Reck to complement this panel. RESULTS IHC analysis revealed that Mmp protein expression peaks at the early stages of folliculogenesis and ovulation, decreases during ovulation-luteogenesis transition and luteogenesis, increasing again during corpus luteum maintenance and luteolysis. The protein expression patterns of these metalloproteinases and Sparc were inverse relative to the pattern displayed by Reck. We observed that the gene expression peaks of Mmps inhibitors Reck and Timp2 were closely paraleled by Mmp2 and Mmp9 suppression. The opposite was also true: increased Mmp2 and Mmp9 expression was concomitant to reduced Reck and Timp2 levels. CONCLUSION Therefore, our results generate a spatio-temporal expression profile panel of Mmps and their regulators, suggesting that Reck and Sparc seem to play a role during ovarian dynamics: Reck as a possible inhibitor and Sparc as an inducer of Mmps.

Abstract
BACKGROUND To determine whether matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMP-1 and TIMP-2) in human follicular fluid, have any relationships with oocyte maturation in vivo and subsequent fertilization during in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI) cycles. METHODS The follicular fluids were obtained from 150 female patients undergoing IVF/ICSI cycles and a total of 1504 oocytes were retrieved for analysis. MMP-2 and MMP-9 activities were measured using zymography assay. TIMP-1 and TIMP-2 concentrations were quantitatively assessed using enzyme-linked immunosorbent assay (ELISA). RESULTS Human follicular fluid MMP-2 level was significantly associated with the rate of maturity of oocytes (P < 0.001). Furthermore, the MMP-2 was significantly associated with the higher fertilization rate (P < 0.01). There was no significant correlation between follicular MMP-9 and the maturation rate of oocytes. The TIMP-1 and TIMP-2 also showed no correlation with the oocyte maturation rate. CONCLUSIONS The level of gelatinase MMP-2 in human follicular fluid might be a reliable marker of mature oocytes during IVF/ICSI cycles. Furthermore, the MMP-2 expression has a strong association with higher fertilization rate. Further studies are needed to support this theory.

Abstract
PURPOSE To evaluate the latent and active forms of MMP-2 and MMP-9 in human semen samples and to investigate their association with semen parameters. METHODS Basic semen analysis was performed in 82 semen samples. Seminal plasma was analyzed with gelatin zymography. RESULTS Both latent and active forms of MMP-2 and MMP-9 were detected in human seminal plasma. The latent forms were the predominant ones. MMP-2 and MMP-9, either in latent or active forms, were not correlated with semen parameters. ProMMP-9 levels were higher in semen samples with abnormally low concentration (< or = 19 x 10(6)/ml) compared with semen samples with concentration > or = 50 x 10(6)/ml. CONCLUSION MMP-2 and MMP-9 are both present in human semen. The latent forms of both MMPs are the predominant ones. ProMMP-9 is elevated in samples of low sperm concentration.

Abstract
Matrix metalloproteinases (MMP) are capable of degrading a variety of extracellular matrix (ECM) proteins and are also involved in the processing of a number of bioactive molecules. Our findings indicate that the functions of MMP in the ovary and uterus are organ-specific and time-dependently vary during the reproductive cycle. Prolactin induces structural luteolysis indicated by loss of luteal weight, protein and DNA within 36 h after pretreatment with ergot alkaloid. MMP activation appears crucial for the selective depletion of protein during luteal involution, which entails loss of ECM accompanied by apoptosis. During GnRHagonist-induced luteolysis, this response was also associated with marked increases in MMP-2, which degraded collagen type IV, and MT1-MMP, which in addition to activating MMP-2 also degrades collagen type I, III and V. We also found that the level of MT1-MMP and MMP-2 expression in the human CL is greater during the late luteal phase than during either the early mid luteal phases or during gestation, respectively. That dehydroepiandrosterone (DHEA) treatment caused the formation of cysts from antral follicles in the ovaries of immature rats while depressing MMP-2 collagenolytic activity and enhancing lysyl oxidase expression highlights the importance of collagen degradation in the process of ovulation and suggests that changes in the activities of these enzymes play a key role in ovarian cystogenesis in polycystic ovary syndrome patients. Furthermore, immunohistochemical analyses showed that MT1-MMP and FasL co-localize with TdT-mediated dUTP-biotin nick end-labeling (TUNEL)-positive apoptotic granulosa cells in rats treated with DHEA, that the Fas/FasL/Caspase-8 (death receptor-dependent) pathway is pivotal for follicular atresia and that increased levels of MT1-MMP likely play an important role in tissue remodeling during follicular atresia. After parturition, the uterus undergoes involution, a conspicuous feature characterized by a rapid reduction in the collagen content mediated by degradation of extracellular collagen bundles. Our findings strongly suggest that MT1-MMP, MMP-2 and MMP-9 are each time-dependently regulated and play important roles in tissue remodeling during postpartum uterine involution.

Abstract
CONTEXT The molecular mechanisms of luteolysis and its inhibition during maternal recognition of pregnancy remain unclear. OBJECTIVE The objective of this study was to investigate the differential regulation of connective tissue growth factor (CTGF) expression in human corpora lutea using in vivo and in vitro models. DESIGN Corpora lutea from different stages of the luteal phase and after luteal rescue with human chorionic gonadotropin (hCG) were studied. Primary cultures and cocultures of luteinized granulosa cells and luteal fibroblast-like cells were performed. SETTING This study was performed at the research center of a university teaching hospital. PATIENTS Women with regular cycles having hysterectomy for nonmalignant conditions and women undergoing oocyte collection for assisted conception were studied. INTERVENTIONS CTGF localization was determined by in situ hybridization, and expression by quantitative RT-PCR. OUTCOMES The outcome measures were the effect of hCG on the expression and localization of CTGF mRNA in human corpora lutea and the effect of hCG on CTGF expression in primary cultures of luteinized granulosa cells and luteal fibroblast-like cells. RESULTS Luteal rescue reduced CTGF expression compared with that in the late luteal phase (P < 0.05). CTGF expression was localized to fibroblast-like cells and endothelial cells of larger blood vessels, not to steroidogenic cells. The expression of CTGF by fibroblast-like cells in vitro was not regulated by hCG. When cocultured with luteinized granulosa cells, fibroblast-like cell CTGF expression was inhibited by hCG (P < 0.001). This effect was independent of stimulated progesterone concentrations and was not blocked by follistatin or indomethacin. Both IL-1alpha (P < 0.05) and cAMP (P < 0.001) inhibited CTGF expression in fibroblast-like cells. CONCLUSIONS These results provide evidence for negative regulation of CTGF by hCG during luteal rescue mediated by paracrine signals.

Abstract
Angiogenesis is essential for normal growth and function of the corpus luteum. The roles of various angiogenic factors in these events are being elucidated. Endocrine gland vascular endothelial growth factor (EG-VEGF) has recently been described in the human ovary. To define the localization of EG-VEGF mRNA in the corpus luteum and determine changes in its expression, dated human corpora lutea were studied at the early, mid-, and late luteal phases. Quantitative RT-PCR was employed to determine changes in EG-VEGF mRNA and compare expression to its related factor prokineticin-2 and the established angiogenic factor, VEGF. In situ hybridization was used to localize sites of production of EG-VEGF. To investigate whether expression of EG-VEGF was under the influence of LH or progesterone, luteinized granulosa cells were stimulated with human chorionic gonadotropin in the presence or absence of a progesterone synthesis inhibitor. EG-VEGF mRNA increased throughout the luteal phase, whereas there was no change in VEGF mRNA. The relative abundance of RNAs based upon PCR signal intensity showed that VEGF and EG-VEGF were highly expressed, whereas expression of prokineticin-2 was low. EG-VEGF mRNA was localized predominantly to granulosa-derived cells of the corpus luteum. Human chorionic gonadotropin stimulated both VEGF and EG-VEGF mRNA in vitro, but the level of expression was not influenced by progesterone. These results establish that in the human corpus luteum EG-VEGF is principally derived from granulosa lutein cells and that its synthesis is highest during the mid- to late luteal phase.

Abstract
The ovary and uterus undergo extensive tissue remodeling throughout each reproductive cycle. This remodeling of the extracellular environment is dependent upon the cyclic hormonal changes associated with each estrous or menstrual cycle. In the ovary, tissue remodeling is requisite for growth and expansion of the follicle, breakdown of the follicular wall during the ovulatory process, transformation of the postovulatory follicle into the corpus luteum, as well as the structural dissolution of the corpus luteum during luteal regression. In the uterus, there is extraordinary turnover of the endometrial connective tissue matrix during each menstrual cycle. This turnover encompasses the complete breakdown and loss of this layer, followed by its subsequent regrowth. With implantation, extensive remodeling of the uterus occurs to support placentation. These dynamic changes in the ovarian and uterine extracellular architecture are regulated, in part, by the matrix metalloproteinase (MMP) system. The MMP system acts to control connective tissue remodeling processes throughout the body and is comprised of both a proteolytic component, the MMPs, and a regulatory component, the associated tissue inhibitors of metalloproteinases. The current review will highlight the key features of the MMPs and tissue inhibitors of metalloproteinases, focus on the changes and regulation of the MMP system that take place throughout the estrous and menstrual cycles, and address the impact of the dynamic tissue remodeling processes on ovarian and uterine physiology.

Abstract
OBJECTIVE To investigate the regulation of MMP-9, TIMP-1, and progesterone via three signal transduction pathways in luteinized granulosa cells from normal ovulatory and PCOD women. DESIGN In vitro study. SETTING Laboratory for Research in Reproductive Sciences, Department of Obstetrics and Gynecology, Ha'Emek Hospital, Afula, Israel. PATIENT(S) Ten normal ovulatory and 10 women with polycystic ovary disease (PCOD) treated in an assisted reproduction program. INTERVENTION(S) Cultured cells were exposed to phorbol 12-myristate 13-acetate (TPA), acting via protein kinase C (PKC), to epidermal growth factor (EGF), acting via protein tyrosine kinase (PTK), and to forskolin, acting via protein kinase A (PKA). MAIN OUTCOME MEASURE(S) Secretion of MMP-9, TIMP-1, and progesterone. RESULT(S) Phorbol 12-myristate 13-acetate elicited an increase in MMP-9 and TIMP-1 secretion in both groups and apparently did not affect progesterone secretion. Epidermal growth factor did not change significantly neither MMP-9 nor TIMP-1 secretion but dose dependently decreased MMP-9-TIMP-1 ratio and increased progesterone secretion in the PCOD group. Forskolin inhibited MMP-9 activity and increased TIMP-1 and progesterone secretion in both groups. Progesterone production was inversely related to the ratio of MMP-9-TIMP-1 regardless of cell origin. CONCLUSION(S) In this preliminary study, similar and divergent patterns have emerged in the regulation of MMP-9 and TIMP-1 in human luteinized granulosa cells. Repressing MMP-9-TIMP-1 ratio may have an important modulatory effect on progesterone secretion.

Abstract
Follicular formation, growth or atresia, and ovulation as well as luteal formation and subsequent regression are dependent upon cyclical remodeling of the extracellular matrix (ECM). The proteinaceous and nonproteinaceous components of the ECM provide the tissue specific, extracellular architecture to which cells attach. Furthermore, the ECM modulates cellular activities through cellular surface receptors and serves as a reservoir for specific growth factors, cytokines, and binding proteins. The ability of the ECM to direct the proliferation, differentiation and function of cells implicates ECM remodeling in normal ovarian function. Specific components of the ECM are cleaved by matrix metalloproteinases (MMPs) whose activities are specifically inhibited by tissue inhibitors of metalloproteinases (TIMPs). MMPs are zinc- and calcium-dependent enzymes that collectively degrade proteinaceous components of the ECM. Controlled turnover of ECM by MMPs and TIMPs may be essential for creating and (or) preserving microenvironments conducive to follicular and luteal function and is likely dependent upon the ratio of enzyme to inhibitor. To date, most studies have focused upon correlating ovarian expression of MMPs and TIMPs with various stages of the reproductive cycle. From these studies, many potential key regulators of ovarian ECM remodeling have been identified. This review presents evidence for the involvement of MMPs and TIMPs in ECM remodeling associated with follicular and luteal function.

Abstract
Increased matrix metalloproteinase (MMP) expression and activities help to mediate tissue involution through increasing extracellular matrix remodeling and promoting dedifferentiation and, ultimately, apoptosis. Therefore, we hypothesized that prostaglandin (PG) F(2alpha) administration would decrease expression of the tissue inhibitor of metalloproteinase (TIMP)-1, -2, and -3 and effectively increase the MMP:TIMP ratio, leading to glandular involution. In experiment 1, we tested the effects of PGF(2alpha) administration (Day 10 postestrus; Day 0 = estrus) on luteal TIMP-1, -2, and -3 mRNA and protein expression. Corpora lutea were collected at 0, 15, or 30 min or at 1, 2, 4, 6, 12, 24, and 48 h following PGF(2alpha) administration (n = 3-9 animals/time point). Following PGF(2alpha) administration, TIMP-1 mRNA levels decreased (P < 0.05) at 1 and 2 h relative to 0 h (controls), then increased to levels greater than controls at 4 and 6 h. In contrast, TIMP-2 and -3 mRNA levels did not decrease following PGF(2alpha) administration. The TIMP-1, -2, and -3 proteins were localized to large luteal cells (LLCs) within control (untreated) tissues. However, histodepletion of TIMP-1 within LLCs was evident within 30 min (earliest time point collected) following PGF(2alpha) injection and continued through 48 h. Luteal concentration of TIMP-1, as determined by RIA, was decreased (P < 0.05) by 15 min (earliest time point collected) following PGF(2alpha) administration and remained low through 48 h. In contrast, TIMP-2 and -3 immunolocalization was not altered by PGF(2alpha) administration. Experiment 2 was conducted to determine if PGF(2alpha) could initiate the preceding changes in TIMP-1 in early (Day 3) corpora lutea that can bind PGF(2alpha) but are refractory to its luteolytic effects. Serum concentrations of progesterone and luteal concentrations of TIMP-1 mRNA and protein were similar at 0 and 6 h after PGF(2alpha) injection on Day 3 postestrus. These data suggest that an early and sustained effect of PGF(2alpha) is the specific depletion of TIMP-1 within LLCs that are capable of responding to the luteolytic action of PGF(2alpha). This action may increase the MMP:TIMP-1 ratio, creating an environment that favors extracellular matrix degradation and, thereby, facilitates both functional and structural regression.

Abstract
Members of the matrix metalloproteinase (MMP) family collectively degrade extracellular matrix (ECM) and help regulate luteal function. The objectives of these experiments were to characterize the mRNA expression, localization, and activity of MMPs 2, 9, and 14 in ovine corpora lutea (CL). Ovine CL were collected on Days 2, 4, 10, and 15 of the estrous cycle (Day 0 = estrus). Messenger RNA transcripts for MMPs 2 and 14 were detected using Northern analysis; however, expression of MMP-9 was undetectable. Expression of MMP-14 mRNA (membrane type-1 MMP) was increased (P < 0.05) on Day 4; whereas, expression of MMP-2 mRNA was highest (P < 0.05) on Day 10, which corresponded to the observed increases in gelatinolytic activity in luteal homogenates as measured by a fluroscein-labeled gelatin substrate assay. MMP 2 and 9 proteins were localized predominantly to large luteal cells (LLCs), whereas MMP-14 was localized primarily to cells other than LLCs as demonstrated by immunohistochemistry. Immunolocalization of MMP-2 to putative endothelial cells was also observed on Day 15. Localization of MMP activity was determined using in situ zymography. Luteal tissues contained gelatinolytic activity primarily localized pericellularly to various cell types, including LLCs. These results support the hypothesis that ECM remodeling occurs throughout the luteal phase and may help potentiate cellular migration, differentiation, angiogenesis, and growth factor bioavailability.

Abstract
Luteal tissue contains matrix metalloproteinases (MMPs) that cleave specific components of the extracellular matrix (ECM) and are inhibited by tissue inhibitors of metalloproteinases (TIMPs). We previously reported a decrease in luteal TIMP-1 within 15 min of prostaglandin F(2 alpha) (PGF(2 alpha))-induced luteolysis. An increase in the MMP:TIMP ratio may promote ECM degradation and apoptosis, as observed in other tissues that undergo involution. The objectives of these experiments were to determine whether 1) PGF(2 alpha) affects expression of mRNA encoding fibrillar collagenases (MMP-1 and -13), gelatinases A and B (MMP-2 and -9), membrane type (mt)-1 MMP (MMP-14), stromelysin (MMP-3), and matrilysin (MMP-7), and 2) PGF(2 alpha) increases MMP activity during PGF(2 alpha)-induced luteolysis in sheep. Corpora lutea (n = 3-10/time point) were collected at 0, 15, and 30 min and 1, 2, 4, 6, 12, 24, and 48 h after PGF(2 alpha) administration. Northern blot analysis confirmed the presence of all MMPs except MMP-9. Expression of mRNA for the above MMPs (except MMP-2) increased significantly (P < 0.05) by 30 min, and all MMPs increased significantly (P < 0.05) by 6 h after PGF(2 alpha) administration. Expression of MMP-14 mRNA increased significantly (P < 0.05) by 15 min post-PGF(2 alpha) and remained elevated through 48 h. MMP activity in luteal homogenates (following proenzyme activation and inactivation of inhibitors) was increased significantly (P < 0.05) by 15 min and remained elevated through 48 h post-PGF(2 alpha). MMP activity was localized (in situ zymography) to the pericellular area of various cell types in the 0-h group and was markedly increased by 30 min post-PGF(2 alpha). MMP mRNA expression and activity were significantly increased following PGF(2 alpha) treatment. Increased MMP activity may promote ECM degradation during luteolysis.

Abstract
Whereas the mammalian fertilization environment consists of possible products of the mutual interaction between oviductal and follicular fluids in addition to both fluid components, little is known regarding the interaction. In the present study, we have demonstrated that a mutual interaction occurs, resulting in the biochemical changes of follicular fluid components. Gelatin zymographic analyses of bovine follicular fluid (bFF) showed consistently a distinct, gelatinolytic activity having a molecular weight of 110 kDa (GA110) in addition to other gelatinases, whereas bovine oviductal fluid (bOF) showed a lack of GA110. Surprisingly, when bFF was mixed with bOF before zymography, the GA110 of bFF mostly disappeared at a 1:1 (v/v) mixture, completely disappeared at a 1:10 mixture, as fast as within 30 min after mixing. Other bFF gelatinase activities were not affected by bOF at 1:1 or 10:1 mixtures. Addition of EDTA or phenanthroline, but not of phenylmethylsulfonyl fluoride or trypsin inhibitor, to the mixture greatly increased the gelatinolytic activity of bFF GA110. The increased activity of bFF GA110 by EDTA was again abolished by subsequent bOF treatment. Addition of aminophenylmercuric acetate to the EDTA-treated bFF also abolished GA110; however, this was accompanied by the disappearance of other gelatinases, except the 62-kDa gelatinase, the activity of which increased as the treatment continued up to 24 h. Addition of EDTA or phenanthroline to the gelatin gel incubation buffer after electrophoresis abolished almost all gelatinases of bFF, except those of 88-84 kDa, demonstrating that they were indeed gelatinases or isoforms. Bovine serum and fetal bovine serum also showed the presence of GA110, the activity of which was increased by EDTA. However, ovarian granulosa cell homogenate did not exhibit GA110. Immunoblot experiments using antibodies against matrix metalloproteinase (MMP)-2 and MMP-9 demonstrated that bFF GA110 was an isoform of MMP-2, and that the 62-kDa form was an active form of MMP-2. Disappearance of immunoreactive GA110 of bFF and serum by bOF was also observed. Based on these observations, we conclude that bFF and bovine serum share a unique isoform of MMP-2, and that bOF can specifically degrade the isoform, suggesting that a mutual interaction between bFF and bOF could occur at the time of ovulation.

Abstract
Studies suggest that cell-cell interactions may regulate apoptosis; and, in particular, the calcium-dependent cell adhesion molecule N-cadherin has been shown to be capable of modulating this process. Here, we review the evidence that N-cadherin is expressed by human granulosa cells (GCs) and mediates cell-cell adhesion between GCs. There is strong correlation between N-cadherin expression by granulosa or luteal cells and follicular survival in isolated follicles and archival tissue sections. There exists a strong expression of the molecule by GCs in follicles of the resting pool, of growing antral follicles, and of healthy corpora lutea. In contrast, the molecule is lost in degenerating GCs of atretic follicles and in luteal cells of the late luteal phase. Further, the experimental evidence demonstrates that cell-cell adhesion is critical to the survival of GCs and that N-cadherin-mediated cell-cell adhesion is a critical mediator of survival signals and inhibits apoptosis in these cells. Possible mechanisms by which apoptosis may be triggerred in GCs include the downregulation of N-cadherin, which is mediated, at least in part, through the enzymatic cleavage of the extracellular domain of the molecule. Collectively, these observations suggest that downregulation of N-cadherin or the absence of a functional extracellular domain of the molecule prevent GC aggregation and is associated with GC apoptosis. We propose that N-cadherin-mediated GC signaling plays a central role in follicular and luteal cell survival.

Abstract
Matrix metalloproteinases-1 (MMP-1) and -3 (MMP-3) are proteolytic enzymes involved in remodeling the ovarian extracellular matrix throughout the menstrual cycle. The aim of the present study was to evaluate the tissue concentrations of MMP-1 and MMP-3 in the apical wall of atretic follicles (androstenedione/estradiol ratio > 4), tunica albuginea dissected from the ovarian surface overlying areas devoid of follicles, corpus luteum, and tunica albuginea covering the corpus luteum. After extraction of MMPs from the tissue samples, their concentrations in the extracts were measured by enzyme-linked immunosorbent assays (ELISA). Significantly less MMP-1 was detected in the apical wall of atretic follicles compared to tunica albuginea taken from sites devoid of follicles. These data indicate that atresia is associated with relatively low concentrations of MMP-1 in the apical wall of the follicle. Moreover, there was a negative correlation between the amount of MMP-3 and the diameter of follicle. These data suggest that both MMPs play an important role in the final step of atresia. The amount of MMP-1 in the corpus luteum was several times lower than in the other tissues. This is likely due to stabilization of the extracellular matrix during the period of the corpus luteum maintenance. The concentration of MMP-3 did not differ significantly among the examined tissues.

Abstract
Studies suggest that cell-cell interactions may regulate apoptosis, and in particular, the calcium-dependent cell adhesion molecule N-cadherin has been shown to be capable of modulating this process. Rat granulosa cells (GCs) are known to express N-cadherin whereas cAMP is known to induce apoptosis in human and rat GCs. Based on these observations, we hypothesized that N-cadherin regulates human GC apoptosis via a cAMP-dependent mechanism. N-cadherin expression was evaluated in ovarian follicles and corpora lutea utilizing immunohistochemical techniques and in luteinized GCs in culture using immunoblotting, flow cytometric analysis, immunohistochemistry, and indirect immunofluorescence techniques utilizing anti-N-cadherin antibodies directed against both the extracellular and cytoplasmic domains of the molecule. Apoptosis was assessed by TUNEL and DNA fragmentation analysis and confirmed by flow cytometric cell cycle analysis and electron microscopy. The rate of GC apoptosis was found to be two- to three-fold lower among aggregated cells, as compared with single cells. N-cadherin was found to be expressed by aggregating GCs in vitro and GCs cultured in the presence of either N-cadherin function disrupting antibodies or peptides exhibiting enhanced rates of apoptosis. GCs in situ stained intensely for N-cadherin in preantral and normal growing preovulatory follicles as well as early corpora lutea. N-cadherin was weak in atretic follicles and regressing corpora lutea. Exposure of GCs to cAMP increased apoptosis while decreasing N-cadherin protein expression in a dose-dependent manner. Cell culture under serum-free conditions increased apoptosis and decreased N-cadherin expression, in part through cleavage of the extracellular domain of the molecule. The metalloproteinase inhibitor 1-10-phenanthroline inhibited the cleavage of the extracellular domain of N-cadherin and concomitantly inhibited the serum-deprivation-induced apoptosis of aggregated GCs. Collectively, these observations suggest that down-regulation of N-cadherin or the absence of a functional extracellular domain of the molecule prevents cell aggregation and is associated with GC apoptosis. In addition, cAMP induces apoptosis in a dose-dependent manner, and this process is dependent, at least in part, on regulation of the N-cadherin molecule at the surface of the cells. We conclude that N-cadherin-mediated GC signaling plays a central role in follicular and luteal cell survival.
