Abstract
Membrane-type matrix metalloproteinases (MT-MMPs) are cell membrane-tethered proteinases that belong to the family of the MMPs. Apart from their roles in degradation of the extracellular milieu, MT-MMPs are able to activate through proteolytic processing at the cell surface distinct molecules such as receptors, growth factors, cytokines, adhesion molecules, and other pericellular proteins. Although most of the information regarding these enzymes comes from cancer studies, our current knowledge about their contribution in distinct developmental processes occurring in the embryo is limited. In this review, we want to summarize the involvement of MT-MMPs in distinct processes during embryonic morphogenesis, including cell migration and proliferation, epithelial-mesenchymal transition, cell polarity and branching, axon growth and navigation, synapse formation, and angiogenesis. We also considered information about MT-MMP functions from studies assessed in pathological conditions and compared these data with those relevant for embryonic development.

Abstract
Gallbladder bile from 2 fish species, mullet (Mugil liza) and tilapias (Tilapia rendalli), contain substantial matrix metalloproteinases (MMPs). Extensive purification studies were conducted in order to obtain workable samples for SDS-PAGE and zymography analysis. Proteinase activities were assayed by gelatin substrate zymography. Several protein bands were observed, corresponding to molecular weights of 200, 136, 43, 36, 34, 29, 23 and 14 kDa in mullet bile and 179, 97, 79, 61, 54, 45, 36, 33 and 21 kDa in tilapia bile. Specific inhibitor studies were conducted, in which MMPS were inhibited by EDTA and 1,10 phenanthroline, but not by serine and cysteine protease inhibitors, such as phenylmethylsulfonyl fluoride (PMSF) and transepoxysuccinyl-l-leucylamido-l-guanidino butane (E-64), confirming the proteinase identities as MMPs. Differences in proteinase expression were observed in fish from a contaminated and reference site. Some studies regarding MMPs in different fish tissues exist, however this is the first study conducted in fish bile, and their involvement in detoxification processes and organism protection against the effects of aquatic contaminants may be a possibility.

Abstract
Fish are well-recognized bioindicators of environmental contamination. Several recent proteomic studies have demonstrated the validity and value of using fish in the search and discovery of new biomarkers. Certain analytical tools, such as comparative protein expression analyses, both in field and lab exposure studies, have been used to improve the understanding of the potential for chemical pollutants to cause harmful effects. The metallomic approach is in its early stages of development, but has already shown great potential for use in ecological and environmental monitoring contexts. Besides discovering new metalloproteins that may be used as biomarkers for environmental contamination, metallomics can be used to more comprehensively elucidate existing biomarkers, which may enhance their effectiveness. Unfortunately, metallomic profiling for fish has not been explored, because only a few fish metalloproteins have thus far been discovered and studied. Of those that have, some have shown ecological importance, and are now successfully used as biomarkers of environmental contamination. These biomarkers have been shown to respond to several types of environmental contamination, such as cyanotoxins, metals, and sewage effluents, although many do not yet possess any known function. Examples of successes include MMPs, superoxide dismutases, selenoproteins, and iron-bound proteins. Unfortunately, none of these have, as yet, been extensively studied. As data are developed for them, valuable new information on their roles in fish physiology and in inducing environmental effects should become available.

Abstract
The role of matrix metalloproteinases (MMPs) in collagen fibrillogenesis during development has been studied in the well-characterized chicken metatarsal tendon. Collagen fibrils are initially assembled as intermediates, and the mature fibrils assemble by linear and lateral growth from these intermediates. We hypothesize that this involves the turnover of fibril-associated molecules mediated by the expression and activation of matrix metalloproteinase-2 (MMP-2). We demonstrate changes in the ratio of full-length to truncated MMP-2 during tendon development, consistent with enzyme activation. The level of full-length proMMP-2 remains relatively unchanged, although the truncated form of MMP-2 is highest prior to and during fibril growth. Membrane-type matrix metalloproteinase-3 (MT3-MMP, MMP-16) is fibroblast-associated and involved in the regulation of MMP-2 and in direct matrix turnover. The ratio of full-length proMT3-MMP/truncated (active) MT3-MMP has a pattern similar to that of full-length proMMP-2/truncated (active) MMP-2 during tendon development. Regulation of proMMP-2 activation involves complex formation with active MT3-MMP and TIMP-2. The constantly low TIMP-2 expression seen in tendon development is consistent with this role. Isolation of collagen fibrils from pre-fibril growth tendons (14 day) in the presence of activated MMP-2 is associated with premature fibril growth observed as increased fibril diameters compared with controls. These data implicate MMP-2/MT3-MMP in the initiation and progression of fibril growth, matrix assembly, and tendon development. This may involve the turnover of fibril-associated molecules involved in regulating linear and lateral growth, such as small leucine-rich proteoglycans and fibril-associated collagens. Activation of proMMP-2 dependent on MT3-MMP would allow the focal control of turnover.

Abstract
Using zymography and mass spectrometry, we identified for the first time the precursor of chicken matrix metalloprotease 2 (pro-MMP-2) as a complex with TIMP-2 (tissue inhibitor of metalloproteinases) in egg white and yolk. Real-time polymerase chain reaction confirmed that MMP-2 and its inhibitors TIMP-2 and TIMP-3 were expressed all along the oviduct and in the liver of laying hens. We also demonstrated that the processing of pro-MMP-2 into mature MMP-2 by serine proteases does not occur in vivo, although purified pro-MMP-2 undergoes proteolytic maturation by these proteases in vitro. Moreover, the relative pro-MMP-2 activity assessed by gelatin zymography was shown to decrease in egg white during the storage of unfertilized or fertilized eggs. However, the mature form of 62 kDa MMP-2 could not be detected. The fact that MMP-2 is found as a proform in fresh eggs suggests that the activity of this metalloprotease is regulated under specific conditions during embryonic development.

Abstract
Membrane-type 1 matrix metalloproteinase (MT1-MMP) is the most ubiquitous and widely studied of the membrane-type metalloproteinases (MT-MMPs). It was thus surprising to find no published data on chicken MT1-MMP. We report here the characterization of the chicken gene. Its low sequence identity with the MT1-MMP genes of other species, high GC content, and divergent catalytic domain explains the absence of data and our difficulties in characterizing the gene. The absence of structural features in the chicken gene that have been suggested to be critical for the activation of MMP-2 by MT1-MMP; for the effect of MT1-MMP on cell migration and for the recycling of MT1-MMP suggest these features are either not essential or that MT1-MMP does not perform these functions in chickens. Comparison of the expression of chicken MT1-MMP with MT3-MMP and with MMP-2 and MMP-13 has confirmed the previously recognized co-expression of MT1-MMP with MMP-2 and MMP-13 in fibrous and vascular tissues, particularly those surrounding the developing long bones in other species. By contrast, MT3-MMP expression differs markedly from that of MT1-MMP and of both MMP-2 and MMP-13. MT3-MMP is expressed by chondrocytes of the developing articular surface. Similar expression patterns of this group of MT-MMPs and MMPs have been observed in mouse embryos and suggest distinct and specific functions for MT1-MMP and MT3-MMP in skeletal development.

Abstract
Vertebrate long bones are formed by endochondral ossification, a process accompanied by changes in extracellular matrix synthesis and remodeling, performed mainly by the matrix metalloproteinases (MMP). The temporal/spatial expression patterns of 5 members of the MMP family known to be important for endochondral ossification were studied, for the first time, in the turkey growth plate during embryonic and juvenile stages. The expression of MMP-2 was detected in the proliferative zone, MMP-3, MMP-9, and MMP-13 in cells lining the blood vessels; MMP-13 was also detected in hypertrophic chondrocytes. The MMP-16 expression was detected in the reserve zone of the growth plate. These results present a detailed survey of turkey MMP, serving as a data source (atlas) for further studies in this subject.

Abstract
Proper extracellular matrix (ECM) remodeling, mediated by matrix metalloproteinases (MMPs), is crucial for the development and survival of multicellular organisms. Full-length Xenopus laevis membrane type-3 matrix metallo proteinase (MT3-MMP) was amplified by PCR and cloned from a stage 28 Xenopus head cDNA library. A comparison of the derived Xenopus MT3-MMP protein sequence to that of other vertebrates revealed 86% identity with human and mouse and 85% identity with chicken. The expression profile of MT3-MMP was examined during Xenopus embryogenesis: MT3-MMP transcripts were first detected at the later stages of development and were localized to dorsal and anterior structures. During metamorphosis and in the adult frog, MT3-MMP expression was restricted to specific tissues and organs. Treatment of Xenopus embryos with lithium chloride (LiCl), ultraviolet irradiation (UV), or retinoic acid (RA) revealed that MT3-MMP levels increased with LiCl-dorsalizing treatments and decreased with UV-ventralizing and RA-anterior neural truncating treatments. Overexpression of MT3-MMP through RNA injections led to dose-dependent developmental abnormalities and death. Moreover, MT3-MMP overexpression resulted in neural and head structure abnormalities, as well as truncated axes. Taken together, these results indicate that MT3-MMP expression in Xenopus is spatially and temporally restricted. Furthermore, deregulation of MT3-MMP during early embryogenesis has detrimental effects on development.Key words: Xenopus laevis, MT3-MMP, development, ECM, dorsalization, ventralization.

Abstract
Avian corneal development requires cellular invasion into the acellular matrix of the primary stroma. Previous results show that this invasion is preceded by the removal of the fibril-associated type IX collagen, which possibly stabilizes matrices through interfibrillar cross-bridges secured by covalent crosslinks. In the present study, we provide evidence for the expression of three matrix metalloproteinases (MMPs) in early corneas, two of which act cooperatively to selectively remove type IX collagen in situ. In organ cultures, MMP inhibitors (either TIMP-2 or a synthetic inhibitor) resulted in arrested development, in which collagen IX persisted, and the stroma remained compact and acellular. We also show that blocking covalent crosslinking of collagen allows for cellular invasion to occur, even when the removal of type IX collagen is prevented. Thus, one factor regulating corneal invasion is the physical structure of the matrix, which can be modified by either selective proteolysis or reducing interfibrillar cross-bridges. We also detected another level of regulation of cellular invasion involving inhibition by the underlying lens. This block, which seems to influence invasive behavior independently of matrix modification, is a transient event that is released in ovo just before invasion proceeds.

Abstract
To investigate the roles that matrix-degrading proteases may have in development of the chicken embryo, we documented the expression pattern of matrix metalloprotease-2 (MMP-2, 72-kDa type IV collagenase or gelatinase A) and perturbed its function in vitro and in vivo. MMP-2 is expressed as neural crest cells detach from the neural epithelium during an epithelial-mesenchymal transformation (EMT) but is rapidly extinguished as they disperse. It is also expressed in the sclerotome and in the dermis at the time that the EMT is initiated, and also as these cells migrate, and is down-regulated once motility has ceased. These patterns suggest that MMP-2 plays a role in cell motility during the EMT and during later morphogenesis. Inhibitors of MMPs, including BB-94 and TIMP-2 (tissue inhibitor of metalloprotease-2), prevent the EMT that generates neural crest cells, both in tissue culture and in vivo, but do not affect migration of the cells that have already detached from the neural tube. Similarly, knockdown of MMP-2 expression in the dorsal neural tube using antisense morpholino oligos perturbs the EMT, but also does not affect migration of neural crest cells after they have detached from the neural tube. On the other hand, when somites in culture are treated with TIMP-2, some mesenchymal cells are produced, suggesting that they undergo the EMT, but show greatly reduced migration through the collagen gel. MMP-2 is also expressed in mesenchyme where tissue remodeling is in progress, such as in the developing feather germs, in the head mesenchyme, in the lateral plate mesoderm, and in the limb dermis, especially in the regions where tendons are developing. Comparisons of these expression patterns in multiple embryonic tissues suggest a probable role for MMP-2 in the migration phase of the EMT, in addition to mesenchyme dispersion and tissue remodeling.

Abstract
UNLABELLED A newly cloned avian 75-kDa gelatinase B-like enzyme is expressed by the cells surrounding the blood vessels of the growth plate and upregulated by angiogenic substances in cultured chondrocytes. Despite its low homology to mammalian gelatinase-B, the avian 75-kDa seems to function similarly in the context of endochondral bone formation. INTRODUCTION Gelatinase B/metalloproteinase (MMP)-9, a zinc-dependent protease of the MMP family, is a key regulator in the final step of endochondral ossification. Recently an avian 75-kDa gelatinase B-like enzyme that shows low sequence similarity to the mammalian enzyme (59% on the protein level) was cloned and characterized. However, its expression pattern in the chicken growth plate and its role in bone formation have not, so far, been examined. RESULTS Based on the published sequence, we cloned a 700-bp fragment from cDNA of the chicken growth plate and studied its expression pattern in primary chondrocytes. Because the basal expression level of gelatinase B was almost undetectable, we induced its expression by different culturing conditions, the most dramatic induction achieved by treatment with retinoic acid, which is known as an inducer of vascular invasion in the epiphyseal plates. The gelatinolitic activity, checked by zymography, detected bands corresponding to the gelatinase A and B as well as a new high-molecular weight band of approximately 200 kDa. We further studied the expression pattern of gelatinase B by in situ hybridization. The gelatinase B was expressed by the cells surrounding the blood vessels penetrating the growth plate and by chondrocytes located in the front of these vascular invasions in the borders between the bone and the cartilage, resembling the expression of mouse gelatinase B in the growth plate. The induction of rickets by a vitamin D-deficient diet reduced the expression levels of gelatinase B in the growth plate of 12-day-old chickens but did not affect the expression of gelatinase A mRNA. CONCLUSION The chicken growth plate has a distinctly different structure from the mammalian one: it is much wider, it contains more cells in each zone, and the blood vessels penetrate deeper into the hypertrophic zone. Nevertheless, the upregulation of the avian 75-kDa gelatinase B-like enzyme by vitamins A and D, coupled with its perivascular expression pattern in the growth plate, implies a similar role for the mammalian and avian genes in bone formation.

Abstract
The aim of this study was to investigate the involvement of the MT1-MMP/MMP-2 cascade in induced sputum (IS) and bronchoalveolar lavage fluid (BALF) from bronchial asthma (BA) and bronchiectasis (BE) patients and healthy controls. The molecular forms and cellular origins of MT1-MMP and MMP-2 were determined by Western immunoblotting, immunohistochemistry and in situ hybridization. Elevated levels of soluble activated and autocatalyzed MT1-MMP species as well as activated forms of MMP-2 in IS and BALF samples from BA and BE patients were evidenced. The activation degrees of soluble MT1-MMP and MMP-2 were significantly correlated in BA and BE IS and BALF. Only low levels of both these MMPs were observed in healthy control IS and BALF. The co-expression of MMP-2 with MT1-MMP was evidenced by double immunostaining in bronchial epithelial cells, submucosal glandular cells, smooth muscle cells and monocyte/macrophages. The MT1-MMP/MMP-2 cascade is present and active in human inflammatory lung disease fluid and tissue samples. This cascade seemingly reflects the active destructive phases of these chronic lung diseases.

Abstract
It has been suggested that a family of tissue remodelling enzymes called matrix metalloproteinases (MMPs) play a causal role in the process of tail resorption during thyroid hormone-induced metamorphosis of the anuran tadpole; however, this hypothesis has never been directly substantiated. We cloned two new Xenopus MMPs, gelatinase A (MMP-2) and MT3-MMP (MMP-16), and the MMP inhibitor TIMP-2. These clones were used along with several others to perform a comprehensive expression study. We show that all MMPs and TIMP-2 are dramatically induced in the resorbing tail during spontaneous metamorphosis and are spatially coexpressed, primarily in the remodelling mesenchymal tissues. By Northern blotting, we show that all the examined MMPs/TIMP-2 are also induced by treatment of organ-cultured tails with thyroid hormone (T(3)). Using the organ culture model, we provide the first direct evidence that MMPs are required for T(3)-induced tail resorption by showing that a synthetic inhibitor of MMP activity/expression can specifically retard the resorption process. By gelatin zymography, we also show T(3) induction of a fifth MMP, preliminarily identified as gelatinase B (GelB; MMP-9). Moreover, T(3) not only induces MMP/TIMP expression but also MMP activation, and we provide evidence that TIMP-2 participates in the latter process. These findings suggest that MMPs and TIMPs act in concert to effect the dismantling of mesenchymal structures during T(3)-induced metamorphic tadpole tail resorption.

Abstract
The progression of left ventricular (LV) dysfunction is often accompanied by changes in LV geometry and myocardial architecture that can be defined as LV myocardial remodelling. An important event in LV myocardial remodelling is alterations in the extracellular matrix (ECM). A family of zinc-dependent proteases implicated in facilitating myocardial tissue remodelling by degrading components of the ECM are the matrix metalloproteinases (MMPs). The temporal expression of MMPs and the local tissue inhibitors of MMPs (TIMPs) appear to be differentially regulated in several cardiovascular disease states such as myocardial infarction, LV hypertrophy, and dilated cardiomyopathy. Both pharmacological and genetic modulation of myocardial MMP expression has been demonstrated to alter the course of LV myocardial remodelling and LV dysfunction. The induction of MMPs within the myocardium during the heart failure process probably results in liberation of bioactive molecules, proteolytic degradation of ECM structural proteins, and alterations in cell-cell contact and adhesion. Modifying MMP expression and activation may reduce this turmoil within the myocardial interstitium and, in turn, prove to be a useful therapeutic paradigm for heart failure treatment.

Abstract
The bile from turkey (Meleagris gallopavo) gall bladders was found to contain substantial matrix metalloproteinase (MMP) activities using gelatin, collagen, and casein substrate zymography, [3H]labeled collagen degradation assays, and gelatin-agarose affinity purification. Five major bands corresponding to approximate M(w) of 64, 60, 46, 40 and 36 kDa showed gelatinolytic activities. On incubation with p-aminophenylmercuric acetate or thimerosal, the densities of both the 64- and 46-kDa bands decreased with increasing intensities of the 60- and 40-kDa bands. Both the 64- and 60-kDa bands showed collagenolytic activities whereas the caseinolytic activities appeared as diffuse bands corresponding to M(w) of approximately 60, 40 and 36 kDa. Using [3H]collagen as substrate, the bile enzymes showed both a time and concentration-dependent degradation, which could be inhibited by the MMP inhibitors such as EDTA, phenanthroline, and N-[(2R)-2-(hydroxyamido carbonylmethyl)-4-methylpentanonyl]-L-tryptophan methylamide, but not by serine and cysteine protease inhibitors like trans-epoxysuccinyl-L-leucylamido-(4-guanidino)butane, phenylmethylsulfonyl fluoride or leupeptin. Both 60- and the 40-kDa gelatinolytic bands showed affinity adsorption to a gelatin-agarose matrix. The physiological roles of bile MMPs are not clear, but their involvement in the digestive functions of birds are likely.

Abstract
Cleavage of heparan sulfate (HS) proteoglycans affects the integrity and function of tissues and thereby fundamental phenomena, involving cell migration and response to changes in the extracellular microenvironment. The role of HS-degrading enzymes, commonly referred to as heparanases, in normal development has not been identified. The present study focuses on cloning, expression, and properties of a chicken heparanase and its distribution in the developing chicken embryo. We have identified a chicken EST, homologous to the recently cloned human heparanase, to clone and express a functional chicken heparanase, 60% homologous to the human enzyme. The full-length chicken heparanase cDNA encodes a 60-kDa proenzyme that is processed at the N terminus into a 45-kDa highly active enzyme. The most prominent difference between the chicken and human enzymes resides in the predicted signal peptide sequence, apparently accounting for the chicken heparanase being readily secreted and localized in close proximity to the cell surface. In contrast, the human enzyme is mostly intracellular, localized in perinuclear granules. Cells transfected with a chimeric construct composed of the chicken signal peptide preceding the human heparanase exhibited cell surface localization and secretion of heparanase, similar to cells transfected with the full-length chicken enzyme. We examined the distribution pattern of the heparanase enzyme in the developing chicken embryo. Both the chicken heparanase mRNA and protein were expressed, as early as 12 h post fertilization, in cells migrating from the epiblast and forming the hypoblast layer. Later on (72 h), the enzyme is preferentially expressed in cells of the developing vascular and nervous systems. Cloning and characterization of heparanase, the first and single functional vertebrate HS-degrading enzyme, may lead to identification of other glycosaminoglycan degrading enzymes, toward elucidation of their significance in normal and pathological processes.

Abstract
A universal base analogue forms 'base pairs' with each of the natural DNA/RNA bases with little discrimination between them. A number of such analogues have been prepared and their applications as biochemical tools investigated. Most of these analogues are non-hydrogen bonding, hydrophobic, aromatic 'bases' which stabilise duplex DNA by stacking interactions. This review of the literature of universal bases (to 2000) details the analogues investigated, and their uses and limitations are discussed.

Abstract
The contribution of specific type I collagen remodeling in angiogenesis was studied in vivo using a quantitative chick embryo assay that measures new blood vessel growth into well-defined fibrillar collagen implants. In response to a combination of basic fibroblast growth factor (bFGF) and vascular endothelial growth factor (VEGF), a strong angiogenic response was observed, coincident with invasion into the collagen implants of activated fibroblasts, monocytes, heterophils, and endothelial cells. The angiogenic effect was highly dependent on matrix metalloproteinase (MMP) activity, because new vessel growth was inhibited by both a synthetic MMP inhibitor, BB3103, and a natural MMP inhibitor, TIMP-1. Multiple MMPs were detected in the angiogenic tissue including MMP-2, MMP-13, MMP-16, and a recently cloned MMP-9-like gelatinase. Using this assay system, wild-type collagen was compared to a unique collagenase-resistant collagen (r/r), with regard to the ability of the respective collagen implants to support cell invasion and angiogenesis. It was found that collagenase-resistant collagen constitutes a defective substratum for angiogenesis. In implants made with r/r collagen there was a substantial reduction in the number of endothelial cells and newly formed vessels. The presence of the r/r collagen, however, did not reduce the entry into the implants of other cell types, that is, activated fibroblasts and leukocytes. These results indicate that fibrillar collagen cleavage at collagenase-specific sites is a rate-limiting event in growth factor-stimulated angiogenesis in vivo.

Abstract
We have isolated a novel 75-kDa gelatinase from a chicken macrophage cell line, HD11. Biochemical and immunological characterization of the purified enzyme demonstrated that it is distinct from the chicken 72-kDa gelatinase A (MMP-2). The enzyme is capable of specific gelatin binding and rapid gelatin cleavage. Incubation with an organomercurial compound (p-aminophenylmercuric acetate) induces proteolytic processing and activation of this enzyme, and the resultant gelatinolytic activity is sensitive to both zinc chelators and tissue inhibitors of metalloproteinases. A full-length cDNA for the enzyme has been cloned, and sequence analysis demonstrated that the enzyme possesses the characteristic multidomain structure of an MMP gelatinase including a cysteine switch prodomain, three fibronectin type II repeats, a catalytic zinc binding region, and a hemopexin-like domain. The 75-kDa gelatinase is produced by phorbol ester-treated chicken bone marrow cells, monocytes, and polymorphonuclear leukocytes, cell types that charac- teristically produce the 92-kDa mammalian gelatinase B (MMP-9). The absence of a 90-110-kDa gelatinase in these cell types indicates that the 75-kDa gelatinase is likely the avian counterpart of gelatinase B. However, the protein is only 59% identical to human gelatinase B, whereas all previously cloned chicken MMP homologues are 75-90% identical to their human counterparts. In addition, the new 75-kDa chicken gelatinase lacks the type V collagen domain that is found in all mammalian gelatinase Bs. Furthermore, the secreted enzyme appears structurally distinct from known gelatinase Bs and the activated enzyme can cleave fibronectin, which is not a substrate for mammalian gelatinase B. Thus the results of this study indicate that a second MMP gelatinase exists in chickens, and although it is MMP-9/gelatinase B-like in its overall domain structure and expression pattern, it appears to be biochemically divergent from mammalian gelatinase B.

Abstract
It has been argued that matrix metalloproteinases play important roles in cellular differentiation and regeneration in certain systems. While studying changes in gene expression associated with the phenomena of cornea/lens transdifferentiation ("lens regeneration"), which takes place in the larva of Xenopus laevis, we identified the Xenopus gelatinase B gene. The open reading frame is homologous to other gelatinase B genes identified in other species and encodes all of the domains characteristic of this protein. Xenopus gelatinase B (Xmmp-9) is first expressed during early tail-bud stages in a subset of mesodermal cells scattered throughout the body. Expression is also seen in the peripheral tissues of the developing liver diverticulum, the hindgut/cloaca, and the paired caudal vein, and its dorsal branch in the larval tail. Given the significant role of matrix metalloproteinases in degrading components of the extracellular matrix, Xmmp-9 expression may be important in the morphogenesis of these structures. Xmmp-9 expression was also examined during the processes of cornea/lens transdifferentiation, epithelial wound healing, and limb regeneration in Xenopus larvae. Although Xmmp-9 is expressed very early during cornea/lens transdifferentiation, expression is restricted to the site of the peripheral wound created by removal of the original lens, which triggers transdifferentiation. Expression was not found in the central, uninjured area of the cornea where transdifferentiation takes place. Therefore, Xmmp-9 does not appear to play an important role in cornea/lens transdifferentiation. Xmmp-9 expression is associated with other epithelial wounds, indicating that gelatinase B is expressed in the general context of wound healing in Xenopus. Finally, Xmmp-9 is expressed in the ectoderm and mesoderm at the tip of the amputated limb, very early during limb regeneration, where it is argued to play a role in this process.

Abstract
A matrix metalloproteinase (MMP)-like gene was identified in mouse to contain a conserved MMP catalytic domain and an RRRR motif. It lacks a classic cysteine switch, but it possesses two novel motifs: a cysteine array (Cys-X(6)-Cys-X(8)-Cys-X(10)-Cys-X(3)-Cys-X(2)-Cys), and a novel Ig-fold. It is named CA-MMP after the distinct cysteine array motif, and little is known about its biochemical function. In an attempt to characterize CA-MMP activity, the full-length sequence was expressed in mammalian cells and its product found to be cell-associated without detectable secretion. In light of this unusual finding, a chimera combining the catalytic domain of CA-MMP with the prodomain of stromelysin-3 was constructed to express a fully active enzyme in mammalian cells. Purified CA-MMP catalytic domain expresses proteolytic activity against protein substrates in an MMP inhibitor sensitive fashion. Taken together, it is concluded that CA-MMP is an MMP with distinct structure, biochemical properties and evolutionary history that may define a new subclass of the MMP superfamily.

Abstract
The activation of pro matrix metalloproteinases (MMPs) by sequential proteolysis of the propeptide blocking the active site cleft is regarded as one of the key levels of regulation of these proteinases. Potential physiological mechanisms including cell-associated plasmin generation by urokinase-like plasminogen activator, or the action of cell surface MT1-MMPs appear to be involved in the initiation of cascades of pro MMP activation. Gelatinase A, collagenase 3 and gelatinase B may be activated by MT-MMP based mechanisms, as evidenced by both biochemical and cell based studies. Hence the regulation of MT-MMPs themselves becomes critical to the determination of MMP activity. This includes activation, assembly at the cell surfaces as TIMP-2 complexes and subsequent inactivation by proteolysis or TIMP inhibition.

Abstract
Activation of secreted latent matrix metalloproteinases (MMPs) is accompanied by cleavage of the N-terminal propeptide, thereby liberating the active zinc from binding to the conserved cysteine in the pro-domain. It has been assumed that an analogous mechanism is responsible for the activation of membrane type 1 MMP (MT1-MMP). Using recombinant wild-type MT1-MMP cDNA and mutant cDNAs transfected into COS-1 cells lacking endogenous MT1-MMP, we have examined the function of the propeptide domain of MT1-MMP. MT1-MMP was characterized by immunoblotting, surface biotinylation, gelatin substrate zymography, and 125I-tissue inhibitor of metalloproteinases 2 (TIMP-2) binding. In contrast to wild-type MT1-MMP-transfected COS-1 cells, transfected COS-1 cells containing a deletion of the N-terminal propeptide domain of MT1-MMP or a chimeric construction (substitution of the pro-domain of MT1-MMP with that of collagenase 3) were functionally inactive in terms of binding of 125I-labeled TIMP-2 to the cell surface and initiating the activation of pro-gelatinase A. These results support the concept that in its native plasma membrane-inserted form, the pro-domain of MT1-MMP plays an essential role in TIMP-2 binding and subsequent activation of pro-gelatinase A.

Abstract
We cloned a novel matrix metalloproteinase (MMP) called CMMP from cultured primary chicken embryo fibroblasts. The cDNA-derived CMMP sequence contains 472 amino acids including a putative 19-residue signal peptide and a unique cysteine in the catalytic domain, an insertion in a sequence motif that binds the structural (noncatalytic) zinc of MMPs. Strikingly, a homologously inserted cysteine is also found in Xenopus XMMP and human MMP19, two recently cloned novel members of the MMP family. Phylogenetic analysis suggest that XMMP and MMP19 represent founding members of the MMP family, whereas CMMP is related to collagenase MMPs. Bacterially produced recombinant CMMP (without the amino-terminal inhibition domain), which was autoproteolyzed at the carboxyl-terminal domain, digested casein and gelatin. As shown by Northern blotting, CMMP mRNA of 1.8 kilobase pairs was constitutively expressed in cultured primary chicken embryo fibroblasts and up-regulated by tumor necrosis factor-alpha and the phorbol ester 12-O-tetradecanoylphorbol-13-acetate, but it was not regulated by interleukin-1, basic fibroblast growth factor, or retinoic acid. CMMP mRNA of 1.8 kb was also detected in the head and body of 8-day-old chicken embryos and dramatically up-regulated in 9-day-old embryos.

Abstract
We cloned a cDNA encoding tissue inhibitor of metalloproteinases-3 (TIMP3) from the frog Xenopus laevis. Similar to TIMP3 from other species, Xenopus TIMP3 has 188 residues including 12 conserved cysteines and Asn184, a putative site for N-linked sugars. Xenopus TIMP3 is 84% identical with human TIMP3. As shown by Northern blotting and RT-PCR, Xenopus TIMP3 mRNA is maternally inherited in eggs and midblastula (stage 8) embryos, downregulated in gastrula and then upregulated in neurula and pretailbud embryos. In select adult tissues, TIMP3 mRNA is present in heart, muscle, liver, skin, intestine and ovaries. These results suggest that TIMP3 is involved in the regulation of expression of matrix metalloproteinases in Xenopus early development and adult tissue remodeling.

Abstract
BACKGROUND Short chain fatty acids derived from dietary fiber may protect against invasive colon cancer by modulating degradative matrix metalloproteinases (MMPs) and protective tissue inhibitor matrix metalloproteinases (TIMPs). Since invasion depends on the MMP/TIMP ratio, we hypothesized that short chain fatty acids inhibit colon cancer invasion by inhibiting MMPs and stimulating TIMPs. MATERIALS AND METHODS SW1116 colon cancer cells were seeded onto Matrigel-coated Boyden chambers and treated with unsupplemented media or media containing 10 mM acetate, propionate, or butyrate. SW1116 invasion was quantitated by light microscopy and conditioned media were assayed by ELISA for MMP-1,2,3,9; TIMP-1,2; MMP/TIMP complex; and urokinase plasminogen activator (uPA). All data are expressed as mean percentage of control +/- SE (n > 6). RESULTS Although all three short chain fatty acids inhibited invasion, butyrate was more potent than either acetate or propionate, inhibiting SW1116 invasion by 35 +/- 1% of control (n = 18, P < .0001) vs. 18 +/- 9% (n = 7, P < .05) for acetate and 10 +/- 6% (n = 7, P < .05) for propionate. MMP-2 was not modulated by any of the short chain fatty acids while MMP-1 was modulated only by butyrate and MMP-3 by propionate. Acetate did not modulate MMPs, TIMP-1, or uPA, but stimulated TIMP-2. In contrast, propionate and butyrate stimulated MMP-9 and TIMP-2 by 119-233% and both inhibited uPA by 8-16%. TIMP-1 was stimulated only by butyrate and actually inhibited by propionate. Only butyrate stimulated both TIMP-1 and TIMP-2. CONCLUSIONS These data suggest that dietary fiber may protect against invasive colon cancer through stimulation of TIMP and inhibition of uPA activities, rather than through short chain fatty acids effects on the activities of the MMPs studied.

Abstract
The matrix metalloproteinases (MMPs) are a family of zinc-containing matrix degrading endopeptidases. A subfamily of membrane type (MT) -MMPs has been described recently. We have determined the structure of the gene (Mmp14) encoding the first MT-MMP to be described, MT1-MMP (MMP-14), and mapped it to mouse chromosome 14. The mouse MMP-14 protein is encoded by ten exons. The novel C-terminal peptide domains of MMP-14 are encoded by a single large exon that also encodes the 3'-untranslated region. The structure of the exons encoding the catalytic domain and pro-domain of MMP-14 is distinct from previously described MMP genes, whereas the exons encoding the hemopexin-like domains are similar to those of most other MMP genes. Mmp14 and the gene for tissue inhibitor of metalloproteinases-2 (Timp2) show a temporally and spatially co-regulated expression during mouse development. They are co-expressed during vascular and urogenital development and during the development of osteocartilaginous and musculotendinous structures. The stringent co-expression of these two genes suggests common regulatory pathways that may have important functional implications for the activation of pro-gelatinase A in health and disease.

Abstract
To study the role of matrix metalloproteinases (MMPs) in early vertebrate development, we cloned cDNAs for six different MMPs from the frog Xenopus laevis embryos at different stages of development and describe here a novel MMP called XMMP. Xenopus XMMP has 604 amino acids including a putative signal peptide of 22 residues. At the carboxyl-terminal end of the propeptide, XMMP has a 37-amino acid-long insertion domain containing a segment that is 38% identical with a rat vitronectin sequence between residues 108-135. Following this domain is an RRKR motif, a putative cleavage site for intracellular activation by furin proteinases. XMMP lacks a proline-rich linker peptide, or hinge region, typically found in other MMPs between the catalytic domain and carboxyl-terminal "hemopexin/vitronectin-like" domain. In XMMP, the carboxyl-terminal domain is composed of four tandem repeats that are 21-33% identical to a sequence (residues 213-264) encoded by vitronectin exon-5. Interestingly, XMMP gene is transiently expressed during Xenopus embryo development. XMMP mRNA of 3.0 kilobase pairs was undetected in the blastula stage embryo, induced in gastrula embryo, expressed in neurula embryo, and then down-regulated in pretailbud embryo. In comparison, other Xenopus MMP genes that we have cloned show a different developmental regulation. In blastula embryo, the only MMP gene expressed was found to be 92-kDa type IV collagenase, which was also expressed in the gastrula, neurula, and pretailbud embryos. Expression of stromelysin-1, stromelysin-3, and two different membrane type-MMPs was first detected in the neurula and pretailbud embryos. These results suggest that MMPs and the novel XMMP reported here play a role in Xenopus early development.
