Abstract
Matrix metalloproteinases (MMPs) are large family of proteinases. In addition to a fundamental role in the remodeling of the extracellular matrix, they also cleave a number of cell surface proteins and are involved in multiple cellular processes. MMP activity is regulated via numerous mechanisms, including inhibition by endogenous tissue inhibitors of metalloproteinases (TIMPs). Similar to MMPs, a role for TIMPs has been established in multiple cell signaling pathways. Aberrant expression of MMPs and TIMPS in renal pathophysiology has long been recognized, and with the generation of specific knockout mice, the mechanistic role of several MMPs and TIMPs is becoming more understood and has revealed both pathogenic and protective roles. This chapter will focus on the expression and localization of MMPs and TIMPs in the kidney, as well as summarizing the current information linking these proteins to acute kidney injury and chronic kidney disease. In addition, we will summarize studies suggesting that MMPs and TIMPs may be biomarkers of renal dysfunction and represent novel therapeutic targets to attenuate kidney disease.

Mol Cell Endocrinol 2015; 412:104-15. [PMID: 26054746 DOI: 10.1016/j.mce.2015.06.001] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/12/2015] [Revised: 05/16/2015] [Accepted: 06/01/2015] [Indexed: 10/23/2022]
Abstract
Tissue inhibitor of metalloproteinase 3 (TIMP3) played a key role in female reproduction. However, its expression and function in goat are still unclear. In the present study, the full-length cDNA of goat TIMP3 was cloned from adult goat ovary; meanwhile, we demonstrated that putative TIMP3 protein shared a highly conserved amino acid sequence with known mammalian homologs. Real-time PCR results showed that TIMP3 was widely expressed in the tissues of adult goat. In the ovary, increasing expression of TIMP3 mRNA was discovered during the growth process of follicle and corpus luteum. Immunohistochemistry results suggested that TIMP3 protein existed in oocytes of all types of follicles, corpus luteum and granulosa and theca cells of primary, secondary, and antral but not primordial follicles. In vitro, human chorionic gonadotropin (hCG) stimulated the expression of TIMP3 in goat granulosa cells. hCG-induced TIMP3 mRNA expression was reduced by the inhibitors of protein kinase A, protein kinase C, MAPK kinase, or p38 kinase. Functionally, over-expression of TIMP3 significantly increased apoptosis and decreased the viability of cultured granulosa cells. Knockdown of TIMP3 could decrease hCG-induced progesterone secretion and the mRNA abundance of key steroidogenic enzymes (StAR, p450scc and HSD3B) as well as ECM proteins (DCN and FN). These findings provided evidence that the hCG induced expression of TIMP3 may play an important role in regulating goat granulosa cell survival and steroidogenesis.

Abstract
A new paradigm of matrix metalloproteinase-2 (MMP-2) action in the heart undergoing oxidative stress has emerged. Although best known for its role in the proteolysis of extracellular protein targets, MMP-2 is also localized to the sarcomere within the cardiomyocyte. Oxidative stress activates full-length MMP-2 without need for proteolytic processing and inactivates an endogenous inhibitor, tissue inhibitor of metalloproteinase-4. MMP-2 proteolyzes specific targets within the cell to cause acute, reversible contractile dysfunction. Inhibitors of MMPs are discussed and their possible use for the therapy of acute heart injury caused by oxidative stress is examined.

Abstract
Matrix metalloproteinases (MMPs) are a large family of proteinases that remodel extracellular matrix (ECM) components and cleave a number of cell surface proteins. MMP activity is regulated via a number of mechanisms, including inhibition by tissue inhibitors of metalloproteinases (TIMPs). Originally thought to cleave only ECM proteins, MMP substrates are now known to include signaling molecules (growth factor receptors) and cell adhesion molecules. Recent data suggest a role for MMPs in a number of renal pathophysiologies, both acute and chronic. This review will focus on the expression and localization of MMPs and TIMPs in the kidney, as well as summarizing the current information linking these proteins to acute kidney injury, glomerulosclerosis/tubulointerstitial fibrosis, chronic allograft nephropathy, diabetic nephropathy, polycystic kidney disease, and renal cell carcinoma.

Abstract
Tissue inhibitor of metalloproteinase-3 (Timp-3), an inhibitor of matrix-degrading enzymes, is an important molecule for maintenance of the extracellular matrix. In this study, we generated Timp-3-deficient mice and used them to examine the effect of Timp-3-deficiency on blood pressure and to investigate the role of Timp-3 in the kidney following unilateral ureteral obstruction. The blood pressure and heart rate of Timp-3-deficient mice were not significantly different from those of wild-type mice. On the other hand, the obstructed kidneys of Timp-3-deficient mice developed more severe hydronephrosis than those of wild-type animals. Matrix metalloproteinase activities assessed by in situ zymography and transforming growth factor-beta expression were elevated in Timp-3-deficient mice. The renal tissues were thinner and the ratio of renal medulla to cortex was significantly lower in the obstructed Timp-3-deficient kidneys. These findings indicate that Timp-3-deficiency does not substantially affect the blood pressure in mice, and that Timp-3 plays an important role in the maintenance of renal macrostructure after unilateral ureteral obstruction.

Abstract
The temporal activity and gene expression of matrix metalloproteinases (MMPs) and tissue inhibitors of matrix metalloproteinase (TIMP) were investigated in a rat model of chronic allograft nephropathy. Gelatinolytic activity of MMP-2 and -9 were demonstrated by zymography, and MMP-2,-9 and TIMP-3 mRNA by in situ hybridization. The generation of fibrosis was determined as total collagen content/DNA. Significantly more latent and active MMP-2, as well as latent MMP-9, were seen in allografts than in autografts. Intense MMP-2 mRNA expression was demonstrated in the allografts during the first 20 days after transplantation, located mainly in the interstitium of the kidney. In addition, some tubular cells expressed MMP-2 mRNA. After day 20, MMP-2 gene expression was faint. MMP-9 mRNA expression in allografts was located mainly in the glomerulus. TIMP-3 mRNA expression was downregulated in allografts. MMP-2, MMP-9 and TIMP-3 seem to play a critical role in the development of fibrosis in the renal allograft.

Abstract
Tissue inhibitors of metalloproteinases (TIMPs) modulate extracellular matrix remodeling during embryonic development and disease. TIMP-3 expression was examined during Xenopus laevis embryogenesis: TIMP-3 transcripts detected in the maternal pool of RNA increased at the mid-blastula transition, decreased dramatically during gastrulation and increased again during neurulation and axis elongation. Interestingly, the decrease during gastrulation was not seen in LiCl treated (dorsalized) embryos. Whole mount in situ hybridization of TIMP-3 using DIG-labeled RNA probes demonstrated that the transcripts were present in all dorsal tissues during embryogenesis, but were prominent only in head structures starting at stage 35. Overexpression of TIMP-3 through transgenesis and RNA injections led to developmental abnormalities and death. Both overexpression strategies resulted in post-gastrulation perturbation including those to neural and head structures, as well as truncated axes. However, RNA injections resulted in more severe early defects such as failure of neural tube closure, and transgenesis caused truncated axes and head abnormalities. No transgenic embryo expressing TIMP-3 survived past stage 40.

Abstract
In an effort to identify novel genes relevant to tumor angiogenesis, we compared the genes expressed in a matched pair composed of vascularized breast tumor and its adjacent normal tissue obtained from the same cancer patient. Using differential display, we identified a cDNA fragment that was reproducibly upregulated in vascularized breast tumor. Up-regulation of this gene fragment in vascularized breast tumor was further verified by semi-quantitative PCR on the same RNA pair using gene-specific primers. The cDNA encoding the full-length ORF of that gene was then cloned by both 3' and 5' RACE. Sequence analysis showed that this gene encodes an ORF of 1353 bp having a hydrophobic N-terminal signal sequence and a cleavage site. We named this novel gene BNF-1 (breast tumor novel factor 1). The mature protein of this gene contains cysteine-rich repeats that are a specific feature of several extracellular matrix proteins including thrombospondin-1, thrombospondin-2, pro-collagen type 1, and von Willebrand Factor 1. PCR analysis of BNF-1 expression in a variety of human adult normal tissues revealed that BNF-1 is expressed predominantly in liver, heart, prostate, testis, and ovary. To further study the expression pattern of this novel gene in tumor tissues, we extended our analysis to additional matched pairs of tumor tissues obtained from breast, lung, and colon cancer patients. We show here that BNF-1 is over-expressed not only in breast tumors but also in lung and colon tumors.

Abstract
Using modified differential display, a gene fragment was identified as being over-expressed in human vascularized breast carcinoma when compare to its neighboring normal tissue. The differentially expressed pattern was confirmed by quantitative RT-PCR. Full-length cDNA was then cloned by both 3'-end RACE and 5'-end RACE. Analysis of the full-length cDNA of this gene reveals that this cDNA encodes an open reading frame of 615 bp, which is highly homologous to human protein phosphatase inhibitor-2, with 92% identity at the nucleotide level, and 89% identity at amino acid level. The results of this study suggest that this novel isoform of human protein phosphatase inhibitor-2 (nPPI-2) may be involved in the angiogenic switch during breast tumor development.

Abstract
PURPOSE To evaluate the feasibility of introducing exogenous tissue inhibitor of metalloproteinases-3 gene into the rat retinal pigment epithelium using hemagglutinating virus of Japan liposomes and to assess the effect of tissue inhibitor of metalloproteinases-3 overexpression in retinal pigment epithelium cells on the formation of experimental choroidal neovascularization. METHODS Hemagglutinating virus of Japan liposomes containing hemagglutin epitope-tagged tissue inhibitor of metalloproteinases-3 gene were injected into the subretinal space in rat eyes. Localization of oligonucleotides was evaluated by fluorescence microscopy. Exogenous tissue inhibitor of metalloproteinases-3 mRNA expression was assessed by reverse transcribed polymerase chain reaction. Exogenous tissue inhibitor of metalloproteinases-3 protein expression was visualized by immunostaining with monoclonal antibody 12CA5 against the hemagglutin epitope. Three days after transfection of tissue inhibitor of metalloproteinases-3 gene into retinal pigment epithelium cells, intense laser photocoagulation was performed and the incidence of choroidal neovascularization was assessed by fluorescein fundus angiography. RESULTS Exogenous tissue inhibitor of metalloproteinases-3 mRNA expression in the choroid and retina was detected on day 3. The efficiency of tissue inhibitor of metalloproteinases-3 gene transfection into retinal pigment epithelium cells was greatest on day 7 and decreased gradually thereafter. The incidence of choroidal neovascularization in tissue inhibitor of metalloproteinases-3 gene-transfected eyes was markedly decreased compared with controls. CONCLUSIONS This study shows that tissue inhibitor of metalloproteinases-3 gene can be transferred into rat retinal pigment epithelium using the hemagglutinating virus of Japan-liposome method and that tissue inhibitor of metalloproteinases-3 gene overexpression can inhibit development of experimental choroidal neovascularization. This method may represent a future treatment modality for human macular degeneration associated with choroidal neovascularization.

Abstract
The elucidation of the cellular and molecular mechanisms governing the maturation of the central nervous system (CNS) is rapidly emerging. Cell-cell and cell-matrix interactions play critical roles in all phases of developmental tissue remodeling. Throughout development, an intricate balance between extracellular matrix synthesis and degradation is preserved by the opposing actions of matrix metalloproteinases (MMPs) and their specific inhibitors, the tissue inhibitors of metalloproteinases (TIMPs). Although recent evidence suggests that TIMPs exert diverse cell biological functions distinct from their MMP-inhibitory activities, few studies have investigated MMP or TIMP expression during CNS development. The present report analyzes the mRNA expression of the four known TIMPs throughout the course of embryonic and postnatal rat CNS development. The results clearly demonstrate the unique spatial distribution and temporal regulation of TIMP expression and suggest a distinct role for each TIMP during CNS development.

Abstract
To preserve tissue integrity during the structural rearrangements that occur during central nervous system (CNS) development, an intricate balance between extracellular matrix (ECM) synthesis and degradation must be maintained. The matrix metalloproteinases (MMPs) are believed to be the main mediators of ECM degradation. Because MMPs function in the turnover of a broad-spectrum of ECM proteins their activity is tightly regulated by interaction with tissue inhibitors of metalloproteinases (TIMPs). Whereas the primary function of TIMPs is to inhibit MMP activity, evidence is mounting that TIMPs are multifunctional molecules that exert diverse cell biological functions distinct from their MMP-inhibitory activities. Although the role of MMPs and TIMPs in the morphogenesis of non-neural tissues has been investigated, to date few studies have analyzed MMP or TIMP expression during CNS development. In the present report, we demonstrate the regulation of Timp-3 mRNA expression throughout the course of CNS development. In particular, Timp-3 mRNA is expressed in embryonic ventricular zones and the postnatal subventricular zone (SVZ). In addition, Timp-3 is expressed in the rostral migratory steam (RMS) to the olfactory bulb in a pattern similar to the ECM proteoglycan brevican. These data suggest that TIMP-3 and brevican may act in concert to guide neuronal migration along the RMS.

Abstract
In normal retinas, the phagocytosis of shed photoreceptor outer segments is mediated in part through a mannose receptor protein located in the apical retinal pigment epithelium membrane. As dystrophic rats of the Royal College of Surgeons have a defect in which the retinal pigment epithelium (RPE) is unable to phagocytize the shed outer segments, it is hypothesized that mannose receptor expression will be lost with the progression of photoreceptor degeneration. Immunohistochemical and molecular techniques have been used to study the developmental expression of the mannose receptor in normal and dystrophic retinal pigment epithelium. By immunofluorescence, the mannose receptor is localized to the retinal pigment epithelium, apical membrane region, beginning around 5 days postnatally in both normal and dystrophic retinas. In immunoblots, bands at 175 kDa are labelled by an anti-mannose receptor antibody in apical membrane samples from both normal and dystrophic RPE at all developmental times sampled. RT-PCR analysis reveals that mannose receptor message is present in normal and dystrophic RPE samples at all developmental time points examined. The present study demonstrates that the expression of the mannose receptor begins prior to outer segment differentiation and the initiation of phagocytosis in both normal and dystrophic RPE. Expression of the mannose receptor continues to be unchanged during the progression of photoreceptor degeneration in the dystrophic retina.

Abstract
Cartilage is an avascular and relatively tumor-resistant tissue. Work from a number of laboratories, including our own, has demonstrated that cartilage is an enriched source of endogenous inhibitors of angiogenesis. In the course of a study designed to identify novel cartilage-derived inhibitors of new capillary growth, we have purified an inhibitory protein that was identified by peptide microsequencing and protein database analysis as troponin I (TnI). TnI is a subunit of the troponin complex (troponin-C and troponin-T being the other two), which, along with tropomyosin, is responsible for the calcium-dependent regulation of striated muscle contraction; independently, TnI is capable of inhibiting actomyosin ATPase. Because troponin has never previously been reported to be present in cartilage, we have cloned and expressed the cDNA of human cartilage TnI, purified this protein to apparent homogeneity, and demonstrated that it is a potent and specific inhibitor of angiogenesis in vivo and in vitro, as well as of tumor metastasis in vivo.

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
A complex interplay between enzymes involved in extracellular matrix formation and their inhibitors is thought to control organogenesis during mammalian development. Disturbance of this balance may result in a wide range of diseases, including macular degeneration, arthritis, and tumor metastases. In order to define elements which may be involved in regulating human tissue inhibitor of metalloproteinase 3 (TIMP3) expression, we isolated and sequenced a clone containing 1315 bp of the 5'-upstream region of the human TIMP-3-encoding gene. A 1.2 kb fragment of this clone, which contains multiple motifs which are binding sites for known transcription factors, was used to drive expression of the lacZ reporter gene in multiple lines of transgenic mice. TIMP3 promoter activity, detected through beta-galactosidase histochemical assay, was observed at high levels in selected tissues, the identity of which varied according to developmental stage. TIMP3 promoter activity was detected at embryonic and early postnatal stages in tissues undergoing extensive remodeling, such as developing somites, bones and joints, choroid plexus, webs between the digits, and the spongiotrophoblastic portion of the placenta. In adulthood, TIMP3 promoter activity was restricted to a few tissues which exhibit high metabolic activity or rapid turnover. These include the retinal pigment epithelium (RPE), cells of the kidney cortex, hair follicles, gingiva, ovarian follicles, and testis. The results suggest that TIMP3 expression plays an active role in developmental patterning and in the maintenance of specific differentiated tissues.

Abstract
We have cloned and sequenced the cDNA encoding the rat tissue inhibitor of metalloproteinase 4 (TIMP-4). As a first step towards exploring the role of TIMP-4 in both the physiological and the pathological remodeling of extracellular matrix, we have extensively analyzed the mRNA expression of TIMP-4 in various rat tissues. The results reveal that the expression pattern of rat TIMP-4 is distinct from that of its human and mouse counterparts (Greene et al., 1996; Leco et al., 1997). In this report, we show that rat TIMP-4 is expressed much more extensively than previously reported, which suggests that it may play a significant role in modulating proteolysis of extracellular matrix in a wide range of tissue settings.

Abstract
The tissue inhibitor of metalloproteinase (TIMP) family regulates extracellular matrix turnover and tissue remodeling by forming tight-binding inhibitory complexes with matrix metalloproteinases (MMPs). MMPs and TIMPs have been implicated in many normal and pathological processes, such as morphogenesis, development, angiogenesis, and cancer metastasis. This minireview provides information that would aid in classification of the TIMP family and in understanding the similarities and differences among TIMP members according to the physical data, primary structure, and homology values. Calculations of molecular weight, isoelectric point values, and molar extinction coefficients are reported. This study also compares sequence similarities and differences among the TIMP members through calculations of homology within their individual loop regions and the mature region of the molecule. Lastly, this report examines structure-function relationships of TIMPs. Thorough knowledge of TIMP primary and tertiary structure would facilitate the uncovering of the molecular mechanisms underlying metalloproteinase, inhibitory activities and biological functions of TIMPs.

Abstract
Skin wound healing depends on cell migration and extracellular matrix remodeling. Both processes, which are necessary for reepithelization and restoration of the underlying connective tissue, are believed to involve the action of extracellular proteinases. We screened cDNA libraries and we found that six matrix metalloproteinase genes were highly expressed during rat skin wound healing. They were namely those of stromelysin 1, stromelysin 3, collagenase 3, gelatinase A (GelA), gelatinase B, and membrane type-1 matrix metalloproteinase (MT1-MMP). The expression kinetics of these MMP genes, the tissue distribution of their transcripts, the results of cotransfection experiments in COS-1 cells, and zymographic analyses performed using microdissected rat wound tissues support the possibility that during cutaneous wound healing pro-GelA and pro-gelatinase B are activated by MT1-MMP and stromelysin 1, respectively. Since MT1-MMP has been demonstrated to be a membrane-associated protein (Sato, H., T. Takino, Y. Okada, J. Cao, A. Shinagawa, E. Yamamoto, and M. Seiki. 1994. Nature (Lond.). 370: 61-65), our finding that GelA and MT1-MMP transcripts were expressed in stromal cells exhibiting a similar tissue distribution suggests that MT1-MMP activates pro-GelA at the stromal cell surface. This possibility is further supported by our observation that the processing of pro-GelA to its mature form correlated to the detection of MT1-MMP in cell membranes of rat fibroblasts expressing the MT1-MMP and GelA genes. These observations, together with the detection of high levels of the mature GelA form in the granulation tissue but not in the regenerating epidermis, suggest that MT1-MMP and GelA contribute to the restoration of connective tissue during rat skin wound healing.
