Abstract
Preserving the potency of stem cells in adult tissues is very demanding and relies on the concerted action of various cellular and non-cellular elements in a precise stoichiometry. This balanced microenvironment is found in specific anatomical "pockets" within the tissue, known as the stem cell niche. In this review, we explore the interplay between stem cells and their niches, with a primary focus on skeletal muscle stem cells and the extracellular matrix (ECM). Quiescent muscle stem cells, known as satellite cells are active producers of a diverse array of ECM molecules, encompassing major constituents like collagens, laminins, and integrins, some of which are explored in this review. The conventional perception of ECM as merely a structural scaffold is evolving. Collagens can directly interact as ligands with receptors on satellite cells, while other ECM proteins have the capacity to sequester growth factors and regulate their release, especially relevant during satellite cell turnover in homeostasis or activation upon injury. Additionally, we explore an evolutionary perspective on the ECM across a range of multicellular organisms and discuss a model wherein satellite cells are self-sustained by generating their own niche. Considering the prevalence of ECM proteins in the connective tissue of various organs it is not surprising that mutations in ECM genes have pathological implications, including in muscle, where they can lead to myopathies. However, the particular role of certain disease-related ECM proteins in stem cell maintenance highlights the potential contribution of stem cell deregulation to the progression of these disorders.

Abstract
Basement membrane (BM) zone-associated collagen XV (ColXV) has been shown to suppress the malignancy of tumour cells, and its restin domain can inhibit angiogenesis. In human breast cancer, as well as in many other human carcinomas, ColXV is lost from the epithelial BM zone prior to tumour invasion. Here, we addressed the roles of ColXV in breast carcinogenesis using the transgenic MMTV-PyMT mouse mammary carcinoma model. We show here for the first time that the inactivation of Col15a1 in mice leads to changes in the fibrillar tumour matrix and to increased mammary tumour growth. ColXV is expressed by myoepithelial and endothelial cells in mammary tumours and is lost from the ductal BM along with the loss of the myoepithelial layer during cancer progression while persisting in blood vessels and capillaries, even in invasive tumours. However, despite the absence of anti-angiogenic restin domain, neovascularisation was reduced rather than increased in the ColXV-deficient mammary tumours compared to controls. We also show that, in robust tumour cell transplantation models or in a chemical-induced fibrosarcoma model, the inactivation of Col15a1 does not affect tumour growth or angiogenesis. In conclusion, our results support the proposed tumour suppressor function of ColXV in mammary carcinogenesis and reveal diverse roles of this collagen in different cancer types.

Abstract
Type XV collagen is a non-fibrillar collagen that is associated with basement membranes and belongs to the multiplexin subset of the collagen superfamily. Collagen XV was initially studied because of its sequence homology with collagen XVIII/endostatin whose anti-angiogenic and anti-tumorigenic properties were subjects of wide interest in the past years. But during the last fifteen years, collagen XV has gained growing attention with increasing number of studies that have attributed new functions to this widely distributed collagen/proteoglycan hybrid molecule. Despite the cumulative evidence of its functional pleiotropy and its evolutionary conserved function, no review compiling the current state of the art about collagen XV is currently available. Here, we thus provide the first comprehensive view of the knowledge gathered so far on the molecular structure, tissue distribution and functions of collagen XV in development, tissue homeostasis and disease with an evolutionary perspective. We hope that our review will open new roads for promising research on collagen XV in the coming years. Type XV collagen belongs to the multiplexin subset of the collagen superfamily. It is evolutionarily conserved collagen and associated with basement membranes. This collagen/proteoglycan hybrid molecule contains an anti-angiogenic restin domain. It has important functions in the cardiovascular and the neuromuscular systems. Its expression is dysregulated in various diseases including cancers.

Collagen XV inhibits epithelial to mesenchymal transition in pancreatic adenocarcinoma cells. PLoS One 2013; 8:e72250.

Abstract
Collagen XV (COLXV) is a secreted non-fibrillar collagen found within basement membrane (BM) zones of the extracellular matrix (ECM). Its ability to alter cellular growth in vitro and to reduce tumor burden and increase survival in vivo support a role as a tumor suppressor. Loss of COLXV during the progression of several aggressive cancers precedes basement membrane invasion and metastasis. The resultant lack of COLXV subjacent to the basement membrane and subsequent loss of its interactions with other proteins in this zone may directly impact tumor progression. Here we show that COLXV significantly reduces invasion of pancreatic adenocarcinoma cells through a collagen I (COLI) matrix. Moreover, we demonstrate that epithelial to mesenchymal transition (EMT) in these cells, which is recapitulated in vitro by cell scattering on a COLI substrate, is inhibited by over-expression of COLXV. We identify critical collagen-binding surface receptors on the tumor cells, including the discoidin domain receptor 1 (DDR1) and E-Cadherin (E-Cad), which interact with COLXV and appear to mediate its function. In the presence of COLXV, the intracellular redistribution of E-Cad from the cell periphery, which is associated with COLI-activated EMT, is inhibited and concurrently, DDR1 signaling is suppressed. Furthermore, continuous exposure of the pancreatic adenocarcinoma cells to high levels of COLXV suppresses endogenous levels of N-Cadherin (N-Cad). These data reveal a novel mechanism whereby COLXV can function as a tumor suppressor in the basement membrane zone.

Abstract
In mammals, collagen XV is primarily expressed in skeletal and cardiac muscles, and loss of its expression in mice results in a mild skeletal myopathy. We recently identified Col15a1a, a zebrafish ortholog of the human collagen XV gene which expression was restricted to notochord in embryos. Col15a1a knockdown led to defects in muscle maintenance via Shh signaling. Here we report that zebrafish express a second ortholog Col15a1b. The identification of its complete primary sequence showed that the overall structure of collagen XV is well conserved between vertebrates. Whole mount in situ hybridization and RT-PCR analysis revealed that at 12hpf Col15a1b is mainly expressed in slow muscle cell lineage and in nervous tissues, and, at later stages transcripts are detected in eyes, otic placodes and aortic arches. Based on the expression pattern of col15a1b, sequence alignments and synteny comparisons, we conclude that, contrary to collagen XVa, the zebrafish collagen XVb likely displays the same or similar function than the mammalian orthologs.

Abstract
AIM: To construct a vector containing human restin gene and observe its expression in gastric cancer cells BGC-803 with green fluorescence protein as the reporter gene.
METHODS: Restin gene was amplified from mRNA of fetal kidney tissue by RT-PCR. The RT-PCR products and pEGFP-C1 were simultaneously digested, then purified, ligated, and transformed to construct the recombinant vector pEGFP-restin. Then the recombinant pEGFP-restin was transfected into gastric cancer cells BGC-803. The expression of green fluorescence protein was observed by fluorescence microscopy, and Western blot was used to examine the expression of target protein.
RESULTS: Agarose gel elctrophrosis showed a 600-bp band of the RT-PCR product, which matched the expected size. Through digestion, the inserted DNA sequence was confirmed to be the premature gene of restin, which was ligated to pEGFP-C1 and transfected into BGC-803 cells successfully. The strong expression of green fluorescence protein was observed by fluorescence microscopy, and the expression of target protein was identified using Western blot.
CONCLUSION: The recombinant vector pEGFP-restin is successfully constructed, providing important subject for further investigation of restin function.

Abstract
Muscle cells are surrounded by extracellular matrix, the components of which play an important role in signalling mechanisms involved in their development. In mice, loss of collagen XV, a component of basement membranes expressed primarily in skeletal muscles, results in a mild skeletal myopathy. We have determined the complete zebrafish collagen XV primary sequence and analysed its expression and function in embryogenesis. During the segmentation period, expression of the Col15a1 gene is mainly found in the notochord and its protein product is deposited exclusively in the peri-notochordal basement membrane. Morpholino mediated knock-down of Col15a1 causes defects in notochord differentiation and in fast and slow muscle formation as shown by persistence of axial mesodermal marker gene expression, disorganization of the peri-notochodal basement membrane and myofibrils, and a U-shape myotome. In addition, the number of medial fast-twitch muscle fibers was substantially increased, suggesting that the signalling by notochord derived Hh proteins is enhanced by loss of collagen XV. Consistent with this, there is a concomitant expansion of patched-1 expression in the myotome of morphant embryos. Together, these results indicate that collagen XV is required for notochord differentiation and muscle development in the zebrafish embryo and that it interplays with Shh signalling.

Abstract
Progression of cancer is dependent on acquisition of vascular networks within the tumor. Tumor angiogenesis is dependent on up-regulation of angiogenesis stimulators to overcome the endogenous anti-angiogenic barrier. Such disruption of angiogenesis balance to favor neovascularization is a key step for progression of tumor growth and metastasis. In this regard, the vascular basement membrane and the extracellular matrix have been found to be rich sources of angiogenesis stimulators and inhibitors that become bioavailable on proteolysis of the matrix by tumor microenvironment-related enzymes. In this review the subgroup of endogenous angiogenesis stimulators and inhibitors is discussed, and their mechanism of action during tumor angiogenesis is evaluated. The role in regulating tumor growth and the possibility of using them as prognostic markers for human gastrointestinal cancers is discussed. Furthermore, we specifically address the role of vascular endothelial growth factor in human gastrointestinal cancers and discuss the development and use of bevacizumab (Avastin; anti-vascular endothelial growth factor antibody [Genentech, CA]) in the treatment of colorectal and other gastrointestinal cancers.

Abstract
The goal of this review is to highlight the contribution of extracellular matrix and vascular basement membranes to the regulation of angiogenesis and tumor progression. Here we present a new concept that vascular basement membrane influences endothelial cells and possibly other cell types in a solid state assembled form, and also in a degraded solution state form. Depending on the structural integrity, composition and exposure of cryptic sites, the vascular basement membrane proteome exerts functional influences on proliferating and resting endothelial cells. This review provides the reader with an appreciation of this newly evolved concept in the area of vascular biology.

Abstract
In recent years, the basement membrane (BM)--a specialized form of extracellular matrix (ECM)--has been recognized as an important regulator of cell behaviour, rather than just a structural feature of tissues. The BM mediates tissue compartmentalization and sends signals to epithelial cells about the external microenvironment. The BM is also an important structural and functional component of blood vessels, constituting an extracellular microenvironment sensor for endothelial cells and pericytes. Vascular BM components have recently been found to be involved in the regulation of tumour angiogenesis, making them attractive candidate targets for potential cancer therapies.

Abstract
Collagens IV, XV and XVIII are major components of various basement membranes. In addition to the collagen-specific triple helix, these collagens are characterized by the presence of several non-collagenous domains. It is clear now that these ubiquitous collagen molecules are involved in more subtle and sophisticated functions than just the molecular architecture of basement membranes, particularly in the context of extracellular matrix degradation. Degradation of the basement membrane collagens occurs during numerous physiological and pathological processes such as embryonic development or tumorigenesis and generates collagen fragments. These fragments are involved in the regulation of functions differing from those of their original intact molecules. The non-collagenous C-terminal fragment NC1 of collagen IV, XV and XVIII have been recently highlighted in the literature because of their potential in reducing angiogenesis and tumorigenesis, but it is clear that their biological functions are not limited to these processes. Proteolytic release of soluble NC1 fragments stimulates migration, proliferation, apoptosis or survival of different cell types and suppresses various morphogenetic events.

Abstract
Type XV and type XVIII collagens are classified as part of multiplexin collagen superfamily and their C-terminal parts, endostatin and restin, respectively, have been shown to be anti-angiogenic in vivo and in vitro. The alpha1(XV) and alpha1(XVIII) collagen chains are reported to be localized mainly in the basement membrane zone, but their distributions in blood vessels and nonvascular tissues have yet to be thoroughly clarified. In the present study, we raised monoclonal antibodies against synthetic peptides of human alpha1(XV) and alpha1(XVIII) chains and used them for extensive investigation of the distribution of these chains. We came to the conclusion that nonvascular BMs contain mainly one of two types: subepithelial basement membranes that contained type XVIII in general, or skeletal and cardiac muscles that harbored mainly type XV. But basement membranes surrounding smooth muscle cells in vascular tissues contained one or both of them, depending on their locations. Interestingly, continuous capillaries contained both type XV and type XVIII collagens in their basement membranes; however, fenestrated or specialized capillaries such as glomeruli, liver sinusoids, lung alveoli, and splenic sinusoids expressed only type XVIII in their basement membranes, lacking type XV. This observation could imply that different functions of basement membranes in various tissues and organs use different mechanisms for the endogenous control of angiogenesis.

Abstract
Lack of type XV collagen in mice results in mild skeletal myopathy and increases vulnerability to exercise-induced skeletal muscle and cardiac injury [Proc. Natl. Acad. Sci. USA 98 (2001), 1194]. The expression of type XV collagen was studied during murine fetal development from 10.5 to 18.5 dpc using immunofluorescence. The first sign of type expression was seen in the capillaries of many tissues at 10.5 dpc, some of them showing developmental transitions in the expression. Interestingly, capillaries forming the blood-brain barrier and those of the sinusoidal type were essentially lacking in this collagen. Early expression was also detected in the skeletal muscle and peripheral nerves, while expression in the heart, kidney and lung appeared to be developmentally regulated. In addition, distinct staining was found in the perichondrium of the cartilage. Collectively, the dynamics of its expression during development, its localization in the basement membrane--fibrillar matrix interface and the consequences of its absence in mice suggest a structural role in providing stability at least in skeletal muscle and capillaries. The early prominent expression of type XV collagen in newly forming blood vessels could also indicate a possible role in angiogenic processes.

Abstract
Basement membrane molecules and fragments derived from them are regulators of biological activities such as cell growth, differentiation and migration. This review describes proteolytically derived fragments from the non-collagenous (NC1) domain at the C-terminus of the basement membrane collagens type IV, XV and XVIII, which have been implicated as regulators of angiogenesis. Endostatin is an endogenous collagen XVIII/NC1 derivative, inhibiting endothelial cell proliferation and migration in vitro and tumor-growth in vivo. A homologous NC1 domain fragment of type XV collagen has anti-angiogenic activity as well. Furthermore, NC1 domain fragments of the most abundant basement membrane collagen, type IV collagen, have been shown to inhibit induced vessel growth.

Abstract
In humans, vocal tissue stiffness increases with age, suggesting a possible contribution of age-associated variations in vocal fold collagen turnover to voice senescence. The underlying mechanisms remain to be explored. With the use of reverse-transcriptase polymerase chain reaction (RT-PCR), collagen subtypes expressed in rat vocal folds were determined, and messenger RNA (mRNA) levels of collagens (types I, III, IV, and V), collagen-degrading proteinases (collagenase 3, gelatinase A and B), and tissue inhibitors of metalloproteinases (TIMP-1 to TIMP-4) were measured in vocal folds of neonatal, adult, and elderly rats. Collagens I, III-VIII, XV, XVII, and XVIII are abundantly expressed, whereas collagens II, IX, X, and XI are absent in rat vocal folds. Messenger RNA levels of collagens I, III, IV, and V and collagen-degrading proteinases in the vocal folds of the adult rats are significantly lower than those in the neonates. These mRNA levels show further decline in the vocal folds of the elderly rats, but only the decrease in mRNA levels of collagens I and V significantly differ from the adult levels. There are no marked age-related alterations in vocal fold levels of TIMP mRNAs, and the tissue variation in the gene expression of the aforementioned molecules is minute. Rat vocal folds display tissue-specific expression of collagen genes. Diminished gene expression for collagens and proteinases and unchanged gene expression for TIMPs indicate a slowdown in collagen turnover that may increase the cross-linking of collagen molecules. This observation may explain in part the stiffness that occurs with aging in human vocal folds.

Abstract
Type XV collagen occurs widely in the basement membrane zones of tissues, but its function is unknown. To understand the biological role of this protein, a null mutation in the Col15a1 gene was introduced into the germ line of mice. Despite the complete lack of type XV collagen, the mutant mice developed and reproduced normally, and they were indistinguishable from their wild-type littermates. However, Col15a1-deficient mice showed progressive histological changes characteristic for muscular diseases after 3 months of age, and they were more vulnerable than controls to exercise-induced muscle injury. Despite the antiangiogenic role of type XV collagen-derived endostatin, the development of the vasculature appeared normal in the null mice. Nevertheless, ultrastructural analyses revealed collapsed capillaries and endothelial cell degeneration in the heart and skeletal muscle. Furthermore, perfused hearts showed a diminished inotropic response, and exercise resulted in cardiac injury, changes that mimic early or mild heart disease. Thus, type XV collagen appears to function as a structural component needed to stabilize skeletal muscle cells and microvessels.

Abstract
Isolation and characterization of the mouse gene for the alpha1 chain of type XV collagen (Col15a1) revealed it to be approximately 110 kb in length and contain 40 exons. Analysis of the proximal 5'-flanking region showed properties characteristic of a housekeeping gene promoter, such as an absence of TATA and CAAT boxes, the presence of several transcriptional start sites and a high G+C content. The general organization of the mouse Col15a1 gene was found to be highly similar to that of its human homologue, but the genomic area encoding the end of the N-terminal non-collagenous domain showed marked divergence from the human form. Furthermore, two exons coding for the N-terminal collagenous domain of the human alpha1(XV) chain are lacking in the mouse Col15a1 gene. Due to the lack of two exons and a codon divergence in one exon, the mouse alpha1(XV) chain contains seven collagenous domains, whereas the human equivalent contains nine. Comparison of 5'-flanking sequences indicated four domains that were conserved between the mouse and human genes. Functional analysis of the mouse promoter identified cis-acting elements for both positive and negative regulation of Col15a1 gene expression in mouse NIH/3T3 cells.

Abstract
Endostatin is a fragment of the C-terminal domain NC1 of collagen XVIII that inhibits angiogenesis and tumor growth. We report the characterization of a collagen XV endostatin analogue and its parent NC1 domain, obtained by recombinant expression in mammalian cells. Both NC1 domains contain a trimerization domain, a hinge region that is more sensitive to proteolysis in collagen XVIII and the endostatin domain. Unlike endostatin-XVIII, endostatin-XV does not bind zinc or heparin, which is explained by the crystal structure of endostatin-XV. The collagen XV and XVIII fragments inhibited chorioallantoic membrane angiogenesis induced by basic fibroblast growth factor (FGF-2) or vascular endothelial growth factor (VEGF), but there are striking differences depending on which cytokine is used and whether free endostatins or NC1 domains are applied. The collagen XV and XVIII fragments showed a similar binding repertoire for extracellular matrix proteins. Differences were found in the immunohistological localization in vessel walls and basement membrane zones. Together, these data indentify endostatin-XV as an angiogenesis inhibitor, which differs from endostatin-XVIII in several important functional details.

Abstract
Abstract
Vascular adhesion protein-1 (VAP-1) is an endothelial cell adhesion molecule which mediates lymphocyte binding to endothelial cells. The cloning of a mouse VAP-1 (mVAP-1) cDNA revealed that mVAP-1 is a novel 110/220 kDa transmembrane molecule with significant identity to copper-containing amine oxidases. In this work the nucleotide sequence and primary structure of the mVAP-1 gene was determined and the promoter region was structurally characterized. The isolated approximately 14.4-kb mVAP-1 gene consists of 4 exons and 3 introns. Primer extension analysis and 5′ rapid amplification of cDNA ends revealed multiple transcription initiation sites in different tissues suggesting that the mVAP-1 transcription is differently regulated in different tissues. Analysis of the sequence immediately upstream of the detected transcription initiation sites showed no canonical TATA or CCAAT elements, but putative regulatory elements were found close to the detected transcription start sites. The cloning of the mVAP-1 gene reveals the first insight into the genomic organization of murine amine oxidases and will, by targeted disruption of the gene, allow us to understand better the importance of VAP-1 in leukocyte trafficking and monoamine oxidase activity for the function of the immune system.

Abstract
The human gene for the alpha1 chain of type XV collagen (COL15A1) is about 145 kilobases in size and contains 42 exons. The promoter is characterized by the lack of a TATAA motif and the presence of several Sp1 binding sites, some of which appeared to be functional in transfected HeLa cells. Comparison with Col18a1, which encodes the alpha1(XVIII) collagen chain homologous with alpha1(XV), indicates marked structural homology spread throughout the two genes. The mouse Col18a1 contains one exon more than COL15A1, due to the fact that COL15A1 lacks sequences corresponding to exon 3 of Col18a1, which encodes a cysteine-rich sequence motif. Twenty-five of the exons of the two genes are almost identical in size, six of them contain conserved split codons, and the locations of the respective exon-intron junctions are identical or almost identical in the two genes. The homologous exons include the closely adjacent first pair of exons and the exons encoding a thrombospondin-1 homology found in the N-terminal noncollagenous domain 1, which are followed by the most variable part of the two genes, covering the C-terminal half of their noncollagenous domain 1 and the beginning of the collagenous portion, after which most of the exons are homologous. The lengths of the introns are not similar in these genes, with two exceptions, namely the first intron, which is very short, less than 100 base pairs, and the second intron, which is very large, about 50 kilobases, in both genes. It can be concluded that COL15A1 and Col18a1 are derived from a common ancestor.

Abstract
Palmitoyl protein thioesterase (PPT) is the defective enzyme in infantile neuronal ceroid lipofuscinosis (INCL), which is a recessively inherited, progressive neurodegenerative disorder. We present here the cloning, chromosomal mapping, genomic structure, and the expression of the cDNA of mouse PPT. The mouse PPT gene spans >21 kb of genomic DNA and contains nine exons with a coding sequence of 918 bp. Fluorescence in situ hybridization to metaphase chromosomes localized the mouse PPT gene to the chromosome 4 conserved syntenic region with human chromosome 1p32 where the human PPT is located. PPT is expressed widely in a variety of mouse tissues. The mouse PPT cDNA is conserved highly with the human and rat PPT both at the nucleotide and amino acid sequence level. Transient expression of mouse PPT in COS-1 cells yielded a 38/36-kD differentially glycosylated polypeptide that was also secreted into culture media. Immunofluorescence analysis of transiently transfected HeLa cells indicated lysosomal localization of mouse PPT. Based on the high conservation of the gene and polypeptide structure as well as similar processing and intracellular localization, the function of PPT in mouse and human are likely to be very similar.

Abstract
We report on full-length human type XVIII collagen cDNAs that encode 1516- or 1336-residue alpha 1 (XVIII) chains. The two chains have different signal peptides and variant N-terminal non-collagenous NC1 domains of 493 (NC1-493) and 303 (NC1-303) amino acid residues, respectively, but share 301 residues of their NC1 domains, a 688-residue highly interrupted collagenous portion, and a 312-residue C-terminal non-collagenous portion. Alternative splicing affecting a 43-residue stretch at the junction of the NC1 domain and the beginning of the collagenous portion was identified. The amino acid sequences of the human and previously characterized mouse alpha 1 (XVIII) chains exhibit an overall identity of 79%. The highest homology between these chains was observed in their last 184 residues, corresponding to the proteolytic fragment endostatin, which is capable of inhibiting endothelial cell proliferation, angiogenesis and tumor growth (O'Reilly, et al., Cell 88: 277-285, 1997). Northern analysis of several adult and fetal tissues with a probe for the NC1-493 variant revealed marked amounts of the corresponding 6.2 and 5.0 kb mRNAs in liver, while other tissues contained only faint or undetectable signals. Hybridizations with a probe specific for the NC1-303 variant virtually lacked the liver signal but revealed clear 5.6 and 4.5 kb bands in heart, kidney, placenta, prostate, ovaries, skeletal muscle and small intestine, and faint signals in several other tissues. Thus mRNAs for the long variant occur prominently in liver, while those for the short variant appear to be the major ones in the other tissues analyzed.
