Abstract
Matrix metalloproteinases are proteolytic enzymes that degrade the extracellular matrix and are essential for tissue remodeling. Uterine and cervical growth require remodeling of structural barriers to cell invasion and matrix metalloproteinase-2 and -9 degrade type IV collagen, the major component of basement membranes. Relaxin stimulates uterine and cervical growth and remodeling, which includes remodeling of support elements such as basement membranes. The objective of this study was to determine whether relaxin alters the production and/or activity of matrix metalloproteinase-2 and -9 in the uterus or cervix of the pig. The growth-promoting effects of relaxin were elicited by administering relaxin to prepubertal gilts every 6 h for 54 h. The expression of matrix metalloproteinase-2 and matrix metalloproteinase-9 was characterized by gel zymography, and proteins were quantified by immunoblotting. Total enzyme activity was measured using matrix metalloproteinase-specific fluorescent substrate assays. In both uterine and cervical tissues, immunoreactive matrix metalloproteinase-2 and matrix metalloproteinase-9 protein expression was similar in relaxin-treated and control animals. However, tissue-associated gelatinase activity was attenuated by relaxin (P < 0.05). In contrast, relaxin significantly increased the secretion of active matrix metalloproteinase-2 and -9 protein into uterine fluid (P < 0.05). Given the importance of matrix metalloproteinases in extracellular matrix degradation, the observation that relaxin promotes uterine secretion of matrix metalloproteinase-2 and -9 supports the concept that relaxin facilitates the growth and remodeling of reproductive tissues by increasing extracellular proteolysis in the pig reproductive tract.

Abstract
The expression patterns of matrix metalloproteinase (MMP) family members during the murine estrous cycle and postpartum uterine involution were analyzed, and the consequence of removing specific MMPs during uterine functions was determined using mice deficient in either matrilysin (MAT) or stromelysin-1 (STR-1). In wild-type animals, MAT, STR-1, STR-2, STR-3, and gelatinase A were consistently expressed during the most active phases of the estrous cycle, estrus and proestrus. The messenger RNA for these MMPs as well as collagenase-3 and the tissue inhibitors of metalloproteinases were also expressed during uterine involution, as determined by Northern analysis and in situ hybridization. Notably, MAT, STR-2, and collagenase-3 messenger RNA levels were elevated at early times of involution and rapidly decreased with time, whereas the transcripts for other MMPs remained elevated throughout the involution process. Involution proceeded normally in mice lacking MAT or STR-1; however, the expression of STR-1 and STR-2 was dramatically up-regulated in MAT nullizygous mice, and the expression of MAT and STR-2 was moderately up-regulated in STR-1-deficient animals. We conclude that the concerted action of several MMPs is likely to play an important role in the remodeling of the postpartum uterus, and that mechanisms that compensate for the loss of a specific MMP during this process appear to exist.

Abstract
Rabbit uterine cervical fibroblasts produced a large amount of matrix metalloproteinases (MMPs) such as collagenase (MMP-1) and stromelysin (MMP-3) and a small relatively amount of tissue inhibitor of metalloproteinases (TIMP). When cells were treated with progesterone or oestradiol-17 beta, both steroids concurrently decreased the level of procollagenase and prostromelysin in the culture media and the steady-state levels of the respective mRNAs. On the other hand, the level of TIMP in the culture media and the steady-state level of its mRNA were simultaneously increased by these steroids. Similarly, the suppression of production of MMPs and the augmentation of TIMP production by both steroids were observed with interleukin 1 (IL-1)-treated cells, but the action of progesterone was more effective than that of oestradiol-17 beta in the IL-1-untreated and -treated cells. These results suggest that collagenolysis in uterine cervical fibroblasts is negatively regulated by steroid hormones via the acceleration of TIMP production and the suppression of synthesis of MMPs at the pretranslational level.

Abstract
Activation of procollagenase constitutes a crucial event in collagenolytic activity regulation. In this study we have purified by DEAE-cellulose, Ultrogel AcA-44, and zinc chelate sepharose chromatographies, a procollagenase-activator from the culture medium of the guinea pig carrageenin granuloma model. On SDS-PAGE, the activator migrates as a principal band of Mr approximately 44,000. The molecule activates procollagenase from human lung fibroblasts in a concentration dependent manner and an enhancement of collagenase activity of trypsin-treated crude culture medium was observed. A loss of about 50% of its activity occurs after heating. In addition, this activator degrades gelatin and casein. All these data suggest that this procollagenase-activator might be stromelysin. The activator was found in both phases of the granuloma, at 7 days when collagen is actively deposited and an important proportion of the collagenolytic activity remains in latent form; and at 14 days, when this enzymatic activity is fully expressed.

Abstract
Cervical biopsies were obtained from non pregnant patients and from pregnant at various stages of gestation and during labour. The tissues were extract with a Ca(++)-containing buffer, and collagenase activity was determined in these extracts using a solid phase assay in which triple helical 125I-labelled collagen was cleaved. Collagenase was detected in all samples but significantly elevated activity was only present in labour at 6-8 cm cervical dilatation. This provides direct evidence for the crucial role of specific collagen degradation during cervical ripening and dilatation.

Abstract
An enzyme-linked immunosorbent assay (ELISA) has been developed for rat collagenase. The assay is capable of measuring the enzyme from a variety of rat cell sources at concentrations of 10-50 ng/ml, approximately 500-1,000-fold more sensitive than radiolabelled collagen fibril assay systems. The assay is specific to collagenase from the rat: enzymes from human, tadpole, mouse, and bacterial sources failed to cross-react significantly with rat enzyme. The assay is reproducible and accurate, and is capable of detecting enzyme in the presence of serum or tissue inhibitors. Using the ELISA, we have examined the effect of a variety of hormones on the production of collagenase by rat myometrial smooth muscle cells in culture. Of all the reproductive hormones examined, only progesterone and its synthetic derivative medroxyprogesterone acetate were capable of inhibiting the production of the enzyme by these cells. The maximally effective concentration of progesterone was 1 x 10(-6)M, and that of medroxyprogesterone acetate was 1 x 10(-7)M. The effect of the steroid was selective: no effect on cell proliferation or on general protein synthesis was observed. In addition to the progestational steroids, the glucocorticoids were also capable of inhibiting the production of collagenase by the cells at similar nominal concentrations. However, the myometrial cells were found actively to metabolize progesterone but not hydrocortisone in culture. Thus, the effective inhibitory concentration of progesterone was approximately ten-fold lower than that of hydrocortisone. The results of this study support the concept that progesterone plays a major role in preventing the production of collagenase in the rat uterus.

Abstract
A monospecific antibody to rat uterine collagenase has been produced and employed to study the cell of origin and the time course of production of this enzyme in the involuting rat uterus. The specificity of the anti-collagenase antibody was confirmed by immunoprecipitation, Western analysis, and by its ability to inhibit the activity of collagenase. Parallel measurements of functional enzyme, both latent and active, bound to tissue collagen were also made in nonpregnant, gravid, and postpartum rat uteri. Immunohistochemical staining of collagenase in sections of rat uterus showed the enzyme to be present in the perinuclear region of the smooth muscle cells only of the involuting myometrium. No detectable collagenase was present in the prepartum or nonpregnant uterus. Identity of the smooth muscle cells was confirmed using an anti-smooth muscle actin antibody. In addition, the cultured uterine cells from which the immunizing antigen was obtained were also identified as smooth muscle cells. Specificity of the tissue staining was confirmed by the ability of pure rat uterine collagenase to block the reaction of the antibody with the tissue. These observations indicate that smooth muscle cells are capable of producing collagenase and are consistent with the hypothesis that this enzyme presides over the massive collagen degradation seen in postpartum uterine involution. Furthermore, measurement of collagenase bound to uterine collagen revealed that collagenase activity could be detected only at the time that the cells could be seen to be producing the enzyme by immunolocalization. These findings support the concept that collagenase is produced only as needed and not stored, either intra- or extra-cellularly.

Abstract
Rabbit uterine cervical fibroblast-like cells maintained in fetal calf serum-free medium were found to biosynthesize and secrete a collagenase inhibitor into the culture medium. All the properties of this inhibitor were similar to those that have been described so far for the tissue inhibitor of metalloproteinases. Both progesterone and 17 beta-estradiol significantly increased the level of collagenase inhibitor without the proliferation of cells. These data suggest that both progesterone and estradiol regulate collagenolysis in the uterus bifunctionally by acceleration of the inhibitor production in addition to their known inhibitory actions towards collagenase biosynthesis.

Abstract
A procollagenase from monolayer cultures of postpartum rat uterine cells has been purified. The crucial step in the purification is the binding of the procollagenase from crude, fetal bovine serum-containing culture medium to heparin-Sepharose, followed by elution with extremely low concentrations (5-10 nM) of dextran sulfate. Resultant eluates contain 8-10% procollagenase. Purification is completed by ion-exchange chromatography on DEAE-Sepharose, gel filtration on AcA-44, and chromatography on blue-Sepharose. Rat uterine procollagenase appears as a protein doublet of Mr approximately 58,000, as indicated by two polyacrylamide gel electrophoresis systems, by AcA-44 chromatography, and by equilibrium sedimentation ultracentrifugal analysis. The proenzyme forms are converted by trypsin to an active enzyme doublet of Mr approximately 48,000. Small amounts of active enzyme, which are often generated during the purification, are electrophoretically indistinguishable from trypsin-activated collagenase. Active collagenase can be separated from the zymogen forms by DEAE-Sepharose chromatography. The two forms of the proenzyme doublet can be partially separated by gel filtration on AcA-44 and preliminary analysis indicates each has equal collagenolytic activity. The amino acid analysis of rat uterine collagenase reveals it to be markedly different from two other vertebrate collagenases whose composition is known. The uterine proenzyme is unusually rich in glycine and in the hydroxy amino acids and is considerably more acidic than the human skin fibroblast collagenase, consistent with the different ion-exchange behavior of the two molecules. The specific activity of rat uterine collagenase at 37 degrees C is approximately 3000 micrograms collagen/min/mg, using native reconstituted guinea pig skin type I collagen fibrils as substrate. The enzyme cleaves denatured collagen, but fails to attack a variety of noncollagen proteins.

Abstract
The purification and properties of an estradiol-sensitive hydrolytic activity from mouse uterus which fits several criteria for being an induced protein are described. The activity in the uteri of immature animals can be stimulated 2--4-fold by estradiol to that approaching the adult level. Stimulation is blocked by puromycin. The enzyme which we have designated hydrolase II, was purified approx. 400-fold to apparent homogeneity by chromatography on Affigel Blue, DEAE-cellulose and octyl-Sepharose. Hydrolase II is a single chain polypeptide with an estimated mol. wt = 65,000 daltons and has an N-terminal serine residue. A variety of N-blocked L-amino acid nitrophenyl esters are cleaved by the enzyme. Km's at pH 7.2 were all approx. 40 microns. Of substrates tested, phenylalanine nitrophenyl ester had the highest Vmax. Cbz-beta-alanine nitrophenyl ester, which is not a normal protease substrate was cleaved with a Km of 145 microM. The enzyme had no detectable activity against peptide nitroanilide substrates for trypsin-, chymotrypsin- or elastase-like enzymes. It is inhibited by ZPCK and DIFP but not by TLCK and Ala-Ala-Pro-Ala chloromethyl ketone, a potent inhibitor of elastase-like enzymes. Mouse plasma protein protease inhibitors were without effect as was SBTI. Our results rule out hydrolase II being a carnosinase, non-serine esterase, plasminogen activator, collagenase or collagenase activator and suggest that it is a chymotrypsin-like protease.

Abstract
Twelve enzymatic activities, involved in the metabolism of proteins, collagen, glycosaminoglycans, or in the energy metabolism, were studied in 72 cervical biopsies obtained after delivery of the placenta and in 12 cervices obtained by hysterectomy in nonpregnant patients. Although these activities display high interindividual variations, they are greatly and significantly increased at parturition as compared to the nonpregnant state, with the exception of creatine kinase, which is maximum in cervices obtained from nulliparous nonpregnant women. The activities are low in the group of women who are 35 to 40 years old. The other studied factors (blood group, parity, pregnancy duration, labor length, treatment, state of the cervix at the 9-month examination) have no clear influence on the enzymatic levels. The results are discussed in relation to the well-known structural changes of the cervix at parturition.
