Abstract
Parturition is the final and essential step for mammalian reproduction. While the uterus is quiescent during pregnancy, fundamental changes arise in the myometrial contractility, inducing fetal expulsion. Extracellular matrix (ECM) remodeling is fundamental for these events. The gelatinases subgroup of matrix metalloproteinases (MMPs), MMP2 and MMP9, participate in uterine ECM remodeling throughout pregnancy and parturition. However, their loss-of-function effect is unknown. Here, we determined the result of eliminating Mmp2 and/or Mmp9 on parturition in vivo, using single- and double-knockout (dKO) mice. The dystocia rates were measured in each genotype, and uterine tissue was collected from nulliparous synchronized females at the ages of 2, 4, 9 and 12 months. Very high percentages of dystocia (40-55%) were found in the Mmp2-/- and dKO females, contrary to the Mmp9-/- and wild-type females. The histological analysis of the uterus and cervix revealed that Mmp2-/- tissues undergo marked structural alterations, including highly enlarged myometrial, endometrial and luminal cavity. Increased collagen deposition was also demonstrated, suggesting a mechanism of extensive fibrosis in the Mmp2-/- myometrium, which may result in dystocia. Overall, this study describes a new role for MMP2 in myometrium remodeling during mammalian parturition process, highlighting a novel cause for dystocia due to a loss in MMP2 activity in the uterine tissue.

Abstract
Uterine glands and their secretions are required for conceptus (embryo/fetus and associated placenta) survival and development. In most mammals, uterine gland morphogenesis or adenogenesis is a uniquely postnatal event; however, little is known about the mechanisms governing the developmental event. In sheep, progestin treatment of neonatal ewes permanently ablated differentiation of the endometrial glands. Similarly, progesterone (P4) inhibits adenogenesis in neonatal mouse uterus. Thus, P4 can be used as a tool to discover mechanisms regulating endometrial adenogenesis. Female pups were treated with sesame vehicle alone as a control or P4 from Postnatal Day 2 (PD 2) to PD 10, and reproductive tracts were examined on PD 5, 10, or 20. Endometrial glands were fully developed in control mice by PD 20 but not in P4-treated mice. All other uterine cell types appeared normal. Treatment with P4 stimulated proliferation of the stroma but suppressed proliferation of the luminal epithelium. Microarray analysis revealed that expression of genes were reduced (Car2, Fgf7, Fgfr2, Foxa2, Fzd10, Met, Mmp7, Msx1, Msx2, Wnt4, Wnt7a, Wnt16) and increased (Hgf, Ihh, Wnt11) by P4 in the neonatal uterus. These results support the idea that P4 inhibits endometrial adenogenesis in the developing neonatal uterus by altering expression of morphoregulatory genes and consequently disrupting normal patterns of cell proliferation and development.

Abstract
The uterus is an essential organ for reproduction in mammals that derives from the Müllerian duct. Despite the importance of the uterus for the fertility and health of women and their offspring, relatively little is known about the hormonal, cellular and molecular mechanisms that regulate development of the Müllerian duct and uterus. This review aims to summarize the hormonal, cellular and molecular mechanisms and pathways governing development of the Müllerian duct and uterus as well as highlight developmental programming effects of endocrine disruptor compounds. Organogenesis, morphogenesis, and functional differentiation of the uterus are complex, multifactorial processes. Disruption of uterine development in the fetus and neonate by genetic defects and exposure to endocrine disruptor compounds can cause infertility and cancer in the adult and their offspring via developmental programming. Clear conservation of some factors and pathways are observed between species; therefore, comparative biology is useful to identify candidate genes and pathways underlying congenital abnormalities in humans.

Abstract
In ruminants, the phenomenon of endometrial tissue remodeling during the estrous cycle and early pregnancy is not fully understood. In this report, the occurrence of tissue remodeling, if any, in buffalo endometrium was studied by detecting gelatinases, matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs); the key regulators of tissue remodeling, in uterine luminal fluids (ULF) of cycling and early pregnant (approx. 43-65 days) buffaloes. Each stage of the estrous cycle and pregnant ULF demonstrated a unique profile of gelatinase activities compared to serum/follicular fluid, with a major gelatinase band of 60 kDa with highest activity in early-luteal stage. In addition to a 32 kDa uterus-specific gelatinase band detected in both non-pregnant and pregnant ULFs, the pregnant ULF displayed three new gelatinase bands of 86, 78, and 57 kDa. Western blot technique confirmed the presence of MMP-2 (54 kDa), MMP-9 (76/73 kDa), TIMP-1 (32 kDa), TIMP-2(20 kDa), and two molecular weight forms (31 and 22 kDa) of TIMP-3 in buffalo ULF with varying band intensities. Highest MMP-2 and MMP-9 activities were observed in follicular and early-luteal stage ULFs, respectively. Highest TIMP-1 activity was observed in early-luteal ULF. Interestingly, TIMP-2 activity was only detected in mid-luteal, late-luteal, and follicular stage ULFs with significantly increasing intensities. Highest activities of 31 and 22 kDa TIMP-3 were associated with late-luteal and early-luteal stage ULFs, respectively. The varied activities of MMPs and TIMPs in buffalo ULF during the estrous cycle and early pregnancy might be a reflection of dynamic structural remodeling of the endometrium and/or developing conceptus.

Abstract
Tissue inhibitor of metalloproteinase-1 (TIMP-1) is a multifunctional protein capable of regulating a variety of biological processes in a wide array of tissue and cell types. We have previously demonstrated that TIMP-1 deficient mice exhibit alterations in normal uterine morphology and physiology. Most notably, absence of TIMP-1 is associated with an altered uterine phenotype characterized by profound branching of the uterine lumen and altered adenogenesis. To begin to assess the mechanism by which TIMP-1 may control these uterine events, we utilized steroid-treated ovariectomized wild-type and TIMP-1 null mice exposed to estrogen for 72 hr. Administration of estrogen to TIMP-1 deficient mice resulted in development of an abnormal uterine histo-architecture characterized by increased endometrial gland density, luminal epithelial cell height, and abnormal lumen structure. To determine the mediators which may contribute to the abnormal uterine morphology in the TIMP-1 deficient mice, cDNA microarray analysis was performed. Analysis revealed that expression of two plasmin inhibitors (serpbinb2 and serbinb7) was significantly reduced in the TIMP-1 null mice. Associated with the reduction in expression of these inhibitors was a significant increase in plasmin activity. Localization of the novel uterine serpinb7 revealed that expression was confined to the luminal and glandular epithelial cells. Further, expression of uterine serpinb7 was decreased by estrogen and showed an inverse relationship with plasmin activity. We conclude from these studies that in addition to controlling MMP activity, TIMP-1 may also control activity of serine proteases through modulation of serine protease inhibitors such as serpinb7.

Abstract
Carbonic anhydrases (CAs) are zinc metalloenyzmes that catalyze the reversible conversion of carbon dioxide to carbonic acid and are involved in respiration, calcification, acid-base balance, and formation of fluids. Transcriptional profiling of the developing neonatal mouse uterus detected expression of Car1, Car2, Car11, and Car13 between Postnatal Days (PNDs) 3 and 18. In the neonatal mouse uterus, Car2 and Car11 mRNAs were predominantly localized in endometrial epithelial and stromal cells, respectively, whereas Car13 mRNA was detected in both epithelia and stroma. CAR2 protein was detected primarily in the endometrial epithelia and from PND 3 to PND 18 in the uteri of neonatal mice. To determine whether CA regulated uterine development, neonatal mice were treated s.c. with acetazolamide, a CA inhibitor, from PND 3 to PND 18. Treatment with acetazolamide decreased CA activity in the uterus and the number of endometrial glands without apparent effects on differentiation of the stroma or myometrium. In the neonatal sheep uterus, CA2 mRNA was initially expressed at birth (PND 0) in the endometrial luminal epithelium and was predominantly expressed in the developing glandular epithelium from PND 7 to PND 56. These results support the hypothesis that CA has a functional role in endometrial gland development during postnatal uterine morphogenesis.

Abstract
The uterus is an essential organ for reproduction in mammals. Despite the importance of the uterus for the fertility and health of women and their offspring, relatively little is known about the hormonal, cellular, and molecular mechanisms that regulate development of the uterus in either the fetus or neonate. Disruption of uterine development in the fetus and neonate by genetic defects or exposure to endocrine disruptors can program the function of the uterus in the adult and lead to infertility, cancer, and even death. The intent of this chapter is to review the current knowledge of regulatory factors and pathways governing prenatal organogenesis and postnatal morphogenesis of the uterus in mammals, with a particular focus on laboratory and domestic animals. Prenatal organogenesis, postnatal morphogenesis, and adult functional differentiation of the uterus are complex, multifactorial processes. Although conservation of some factors and pathways are observed between species, it is clear that mutation of candidate genes in the mouse does not always recapitulate the same defects observed in the human. Therefore, comparative biology of the mechanisms regulating uterine development in other species may be useful to identify candidate genes and pathways to understand congenital abnormalities in humans. This knowledge is necessary to develop rational therapies to prevent and treat infertility and to enhance fertility in humans and domestic animals.

Abstract
Postnatal development of the mouse uterus involves differentiation and development of the endometrial glands as well as the myometrium. Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are involved in extracellular matrix breakdown and morphogenesis of many epitheliomesenchymal organs. As a first step to understanding their roles in postnatal mouse uterine development, MMPs and TIMPs found to be expressed in the neonatal mouse uterus by microarray analysis were localized by in situ hybridization. The MMP-2 mRNA was detected only in the uterine stroma, whereas the MMP-10 mRNA was present only in the uterine epithelium from Postnatal Day (PND) 3 to PND 9. All other MMPs (MMP-11, MMP-14, and MMP-23) as well as TIMP-1, TIMP-2, and TIMP-3 were detected in both epithelial and stromal cells of the endometrium, but not in the myometrium. Uterine extracts were then analyzed by gelatin and casein gel zymography to detect active gelatinases and stromelysins, respectively. Five major gelatinase bands of activity were detected and inhibited by the MMP inhibitors, EDTA or 1,10-phenanthroline, but not by PMSF, a serine protease inhibitor. Western blot analysis confirmed the presence of MMP-2 and MMP-9 proteins in the uterus. Immunoreactive MMP-9 protein was detected only in the endometrial stroma, whereas immunoreactive MMP-2 protein was detected in both the stroma and epithelium of the uterus. Casein zymography detected three major bands of activity ( approximately 54, 63, and 80 kDa) that were inhibited by the serine protease inhibitor, PMSF, but not by the MMP inhibitors, EDTA or 1,10-phenanthroline, suggesting that they were serine proteases. These results support the hypothesis that MMPs and TIMPs regulate postnatal development of the mouse uterus.

Abstract
Postnatal uterine development is marked by periods of tissue remodeling. The objective of the present study was to examine the role of tissue inhibitor of metalloproteinase-1 (TIMP-1), a regulator of tissue remodeling events, during postnatal uterine development and to assess the phenotypic consequences of disruption of the TIMP-1 gene product during this time period. To accomplish this goal, wild-type and TIMP-1 null mice were sacrificed at Postnatal Days (PNDs) 5, 10, 15, 20, and 25 and uterine morphology, TIMP expression and matrix metalloproteinase (MMP) activity were assessed. In wild-type mice, TIMP-1 mRNA steady-state levels were highest at PND 5, after which expression decreased. TIMP-2 and TIMP-3 expression in wild-type mice showed no significant changes from PND 5 to 25. In TIMP-1 null mice, TIMP-2 and TIMP-3 expression patterns were similar to those in wild-type counterparts with the exception that, at PND 10, TIMP-2 and TIMP-3 expression was significantly lower in the null mice. Endometrial gland number and uterine histology were similar between genotypes at PNDs 5 and 10, but at PNDs 15 and 20, endometrial glands were more abundant in TIMP-1 null mice. Associated with the increased gland density in the null mice was an increase in total MMP activity above the levels expressed in wild-type mice. In summary, disruption of the TIMP-1 gene product is associated with reduced TIMP-2 and TIMP-3 steady-state mRNA levels, elevated MMP activity, and accelerated endometrial gland formation. We conclude that, during early postnatal uterine development, TIMP-1 may be critical for proper endometrial gland development.

Abstract
Tissue inhibitors of metalloproteinases (TIMPs) are expressed within the uteri of virtually all species where they are postulated to control extracellular matrix turnover, cellular apoptosis, and proliferation. The objective of the current study was to examine the steroidal regulation of uterine TIMP expression and to determine the potential role of the TIMP-1 gene product in this regulation. To accomplish these goals, ovariectomized female TIMP-1 wild-type and null mice were treated with estradiol, progesterone, or estradiol and progesterone and killed at various times after steroid administration. Estradiol induced a significant reduction in uterine TIMP-3 expression in wild-type mice at 8 and 24 h post-steroid administration, but the ability of this steroid to decrease TIMP-3 expression was impaired in the uteri of TIMP-1 null mice. Further, estrogen-induced uterine wet-weight gain/edema was enhanced in the TIMP-1 null mice, and the antiestrogen compound ICI 182780 or progesterone could only partially block this estrogenic effect. It is concluded from this study that steroidal modulation of uterine TIMP-3 expression and regulation of wet-weight gain/edema are altered in TIMP-1 null mice. These observations suggest that steroids induce uterine TIMP-1 expression and, in turn, that TIMP-1 influences TIMP-3 mRNA expression and uterine edema.
