Kukita K, Matsuzaka N, Takai M, Imamura Y, Shin Y. Notch signaling pathway induces expression of type IV collagen in angiogenesis. J Biochem 2024; 175:539-549.

Abstract
Mural cell adhesion is important for the localization of basement membrane components during angiogenesis, and cell-cell interactions are thought to be critical for basement membrane formation. Type IV collagen, a component of the basement membrane, and non-triple helical type IV collagen α1 chain (NTH α1(IV)) co-localize in the basement membrane of neovascular vessels. However, it remains unclear how type IV collagen and NTH α1(IV) are produced around the basement membrane. In the present study, we developed a de novo angiogenesis model using human umbilical vein endothelial cell spheroids and TIG-1 fibroblast cells and demonstrated that NTH α1(IV), probably with α1(IV) chain before forming triple helix molecule, was localized in the fibroblasts in contact with vascular endothelial cells. This localization was disrupted by DAPT, a Notch signaling inhibitor. DAPT treatment also reduced type IV collagen and NTH α1(IV) secretion in TIG-1 fibroblasts, along with diminished COL4A1 and COL4A2 gene expression. Downregulation of Notch3 in TIG-1 fibroblasts decreased the secretion of type IV collagen and NTH α1(IV). Taken together, these findings suggest that heterogeneous and homogeneous intercellular Notch signaling via Notch3 induces type IV collagen and NTH α1(IV) expression in fibroblasts and contributes to basement membrane formation in neovascular vessels.

Lysyl hydroxylase 3-mediated post-translational modifications are required for proper biosynthesis of collagen α1α1α2(IV). J Biol Chem 2022; 298:102713.

Abstract
Collagens are the most abundant proteins in the body and among the most biosynthetically complex. A molecular ensemble of over 20 endoplasmic reticulum resident proteins participates in collagen biosynthesis and contributes to heterogeneous post-translational modifications. Pathogenic variants in genes encoding collagens cause connective tissue disorders, including osteogenesis imperfecta, Ehlers-Danlos syndrome, and Gould syndrome (caused by mutations in COL4A1 and COL4A2), and pathogenic variants in genes encoding proteins required for collagen biosynthesis can cause similar but overlapping clinical phenotypes. Notably, pathogenic variants in lysyl hydroxylase 3 (LH3) cause a multisystem connective tissue disorder that exhibits pathophysiological features of collagen-related disorders. LH3 is a multifunctional collagen-modifying enzyme; however, its precise role(s) and substrate specificity during collagen biosynthesis has not been defined. To address this critical gap in knowledge, we generated LH3 KO cells and performed detailed quantitative and molecular analyses of collagen substrates. We found that LH3 deficiency severely impaired secretion of collagen α1α1α2(IV) but not collagens α1α1α2(I) or α1α1α1(III). Amino acid analysis revealed that LH3 is a selective LH for collagen α1α1α2(IV) but a general glucosyltransferase for collagens α1α1α2(IV), α1α1α2(I), and α1α1α1(III). Importantly, we identified rare variants that are predicted to be pathogenic in the gene encoding LH3 in two of 113 fetuses with intracranial hemorrhage-a cardinal feature of Gould syndrome. Collectively, our findings highlight a critical role of LH3 in α1α1α2(IV) biosynthesis and suggest that LH3 pathogenic variants might contribute to Gould syndrome.

Abstract
Non-triple helical collagen polypeptide α1(IV) (NTH α1(IV)) is a gene product of COL4A1 and is secreted as a polypeptide chain without the triple helix structure under physiological conditions. Studies have shown that NTH α1(IV) is up-regulated in and around vascular endothelial cells during neovascularization and vascular-like networks of in vitro angiogenesis models, suggesting its involvement in angiogenesis. In the present study, we examined the effect of NTH α1(IV) on endothelial cell-to-cell junctions, and we found that NTH α1(IV) suppressed VE-cadherin (vascular endothelial cadherin) mediated junctions and promoted cellular migration in HUVEC cultures. NTH α1(IV) is potentially a factor that induces VE-cadherin endocytosis and promotes neovascular sprouting and elongation. The possible mechanism entails endocytosis of NTH α1(IV) by its cellular receptor(s), Endo180, and/or other proteins, which results in clearance of the cellular receptor(s) from the cell surface, thus inducing the endocytosis of VE-cadherin. Because the NC1 domain of the α1 chain of type IV collagen, called arresten, is considered an endogenous inhibitor of angiogenesis, it seems that the single polypeptide chain of NTH α1(IV) has conflicting functions.

Abstract
The extracellular matrix (ECM) is a highly dynamic noncellular structure that is crucial for maintaining tissue architecture and homeostasis. The dynamic nature of the ECM undergoes constant remodeling in response to stressors, tissue needs, and biochemical signals that are mediated primarily by matrix metalloproteinases (MMPs), which work to degrade and build up the ECM. Research on MMP-9 has demonstrated that this proteinase exists on the cell surface of many cell types in complex with G protein-coupled receptors (GPCRs), and receptor tyrosine kinases (RTKs) or Toll-like receptors (TLRs). Through a novel yet ubiquitous signaling platform, MMP-9 is found to play a crucial role not only in the direct remodeling of the ECM but also in the transactivation of associated receptors to mediate and recruit additional remodeling proteins. Here, we summarize the role of MMP-9 as it exists in a tripartite complex on the cell surface and discuss how its association with each of the TrkA receptor, Toll-like receptors, epidermal growth factor receptor, and the insulin receptor contributes to various aspects of ECM remodeling.

Abstract
Autoantibody against glomerular basement membrane (GBM) plays a direct role in the initiation and development of Goodpasture's (GP) disease. The principal autoantigen is the non-collagenous domain 1 (NC1) of α3 chain of collagen IV, with two immunodominant epitopes, EA-α3 and EB-α3. We recently demonstrated that antibodies targeting α5NC1 are bound to kidneys in GP patients, suggesting their pathogenic relevance. In the present study, we sought to assess the pathogenicity of the α5 autoantibody with clinical and animal studies. Herein, we present a special case of GP disease with circulating autoantibody reactive exclusively to the α5NC1 domain. This autoantibody reacted with conformational epitopes within GBM collagen IV hexamer and produced a linear IgG staining on frozen sections of human kidney. The antibody binds to the two regions within α5NC1 domain, EA and EB, and inhibition ELISA indicates that they are targeted by distinct sub-populations of autoantibodies. Sequence analysis highlights five residues that determine specificity of antibody targeting EA and EB epitopes of α5NC1 over homologous regions in α3NC1. Furthermore, immunization with recombinant α5NC1 domain induced crescentic glomerulonephritis and alveolar hemorrhage in Wistar-Kyoto rats. Thus, patient data and animal studies together reveal the pathogenicity of α5 antibodies. Given previously documented cases of GP disease with antibodies selectively targeting α3NC1 domain, our data presents a conundrum of why α3-specific antibodies developing in majority of GP patients, with α5-specific antibodies emerged in isolated cases, the answer for which is critical for understanding of etiology and progression of the GP disease.

The collagen V homotrimer [alpha1(V)](3) production is unexpectedly favored over the heterotrimer [alpha1(V)](2)alpha2(V) in recombinant expression systems. J Biomed Biotechnol 2010; 2010:376927.

Abstract
Collagen V, a fibrillar collagen with important functions in tissues, assembles into distinct
chain associations. The most abundant and ubiquitous molecular form is the heterotrimer
[α1(V)]2α2(V). In the attempt to produce high levels of recombinant collagen V heterotrimer
for biomedical device uses, and to identify key factors that drive heterotrimeric chain
association, several cell expression systems (yeast, insect, and mammalian cells) have been
assayed by cotransfecting the human proα1(V) and proα2(V) chain cDNAs. Suprisingly, in
all recombinant expression systems, the formation of [α1(V)]3 homotrimers was considerably favored over the heterotrimer. In addition, pepsin-sensitive proα2(V) chains were found in HEK-293 cell media indicating that these cells lack quality control proteins preventing
collagen monomer secretion. Additional transfection with Hsp47 cDNA, encoding the
collagen-specific chaperone Hsp47, did not increase heterotrimer production. Double
immunofluorescence with antibodies against collagen V α-chains showed that, contrary to fibroblasts, collagen V α-chains did not colocalized intracellularly in transfected cells. Monensin treatment had no effect on the heterotrimer production. The heterotrimer production seems to require specific machinery proteins, which are not endogenously
expressed in the expression systems. The different constructs and transfected cells we have
generated represent useful tools to further investigate the mechanisms of collagen trimer
assembly.

Abstract
The matrix metalloproteinases(MMP)-2 and -9, also known as the gelatinases have been long recognized as major contributors to the proteolytic degradation of extracellular matrix during tumor invasion. In the recent years, a plethora of non-matrix proteins have also been identified as gelatinase substrates thus significantly broadening our understanding of these enzymes as proteolytic executors and regulators in various physiological and pathological states including embryonic growth and development, angiogenesis and tumor progression, inflammation, infective diseases, degenerative diseases of the brain and vascular diseases. Although the effect of broad-spectrum inhibitors of MMPs in the treatment of cancer has been disappointing in clinical trials, novel mechanisms of gelatinase inhibition have been now identified. Inhibition of the association of the gelatinases with cell-surface integrins appears to offer highly specific means to target these enzymes without inhibiting their catalytic activity in multiple cell types including endothelial cells, tumor cells and leukocytes. Here, we review the multiple functions of the gelatinases in cancer, and especially their role in the tumor cell migration and invasion.

Abstract
Proteolytic cleavage of extracellular matrix (ECM) is a critical regulator of many physiological and pathological events. It affects fundamental processes such as cell growth, differentiation, apoptosis and migration. Most proteases are produced as inactive proenzymes that undergo proteolytic cleavage for activation. Proteolytic activity is additionally modified by endogenous inhibitors. Mechanisms that localize and concentrate protease activity in the pericellular microenvironment of cells are prerequisites for processes like angiogenesis, bone development, inflammation and tumor cell invasion. Methods that enable real-time, high-resolution imaging and precise quantification of local proteolytic activity in vitro and in vivo remain major challenges. These methods will play an important role in the understanding of basic principles e.g. in cancer cell invasion, the identification of new therapeutical targets and hence drug design. This review highlights mechanisms and functions of local proteolytic activity with special emphasis on tumor cell invasion and metastasis, and focuses on techniques for the investigation of this process.

Abstract
Association of matrix metalloprotease 9 (MMP9) to the cell membrane is considered important in tumor growth and angiogenesis. To dissect this regulatory mechanism, we generated raft and non-raft MMP9 chimeras to force membrane expression in the MCF-7 human breast carcinoma cell line. MMP9 targeting to non-raft cell surface domains rendered a constitutive active membrane MMP9 form, suggesting a contribution by the lipid environment in MMP activation. We generated human breast cancer xenograft models using MCF-7 cells overexpressing secreted and membrane-anchored MMP9. The non-raft MMP9 chimera was constitutively active at the cell membrane in xenografts, but this activation did not correlate with an increase in MMP9-induced angiogenesis. Capillary number and vessel perimeter were specifically increased only in tumors overexpressing wild-type MMP9 (the secreted form); this increase was inhibited when tumors were induced in doxycycline-treated mice. Xenografts from tumor cells overexpressing wild-type MMP9 showed increased vascular endothelial growth factor (VEGF)/VEGFR2 receptor association, which was also dependent on MMP9 activity. These observations indicate that membrane location can influence MMP9 activity in vitro and in vivo, and confirm the relevance of stromal-associated, but not tumor-bound MMP9 in mediating tumor-induced angiogenesis.

Abstract
Local disruption of the integrity of both the myoepithelial cell layer and the basement membrane is an indispensable prerequisite for the initiation of invasion and the conversion of human breast ductal carcinoma in situ (DCIS) to infiltrating ductal carcinoma (IDC). We previously reported that human endometase/matrilysin-2/matrix metalloproteinase (MMP) 26-mediated pro-gelatinase B (MMP-9) activation promoted invasion of human prostate carcinoma cells by dissolving basement membrane proteins (Y. G. Zhao et al., J. Biol. Chem., 278: 15056-15064, 2003). Here we report that tissue inhibitor of metalloproteinases (TIMP)-2 and TIMP-4 are potent inhibitors of MMP-26, with apparent K(i) values of 1.6 and 0.62 nM, respectively. TIMP-2 and TIMP-4 also inhibited the activation of pro-MMP-9 by MMP-26 in vitro. The expression levels of MMP-26, MMP-9, TIMP-2, and TIMP-4 proteins in DCIS were significantly higher than those in IDC, atypical intraductal hyperplasia, and normal breast epithelia adjacent to DCIS and IDC by immunohistochemistry and integrated morphometry analysis. Double immunofluorescence labeling and confocal laser scanning microscopy revealed that MMP-26 was colocalized with MMP-9, TIMP-2, and TIMP-4 in DCIS cells. Higher levels of MMP-26 mRNA were also detected in DCIS cells by in situ hybridization.

Abstract
A human chondrosarcoma cell line, CS-1, was treated successively with increasing concentrations of the marine chemotherapeutic Ecteinascidin-743 (ET-743), yielding a variant cell line displaying a significant degree of resistance to the cytotoxic action of this drug. Various experiments were performed to discern molecular aberrations between the parent and resistant cell line, and also identify potential molecular markers indicative of drug resistance. Although no significant differences in the levels of membrane transporters such as P-glycoprotein or multidrug resistance protein 1 (MRP1) were detected, the cell migratory ability of the ET-743-resistant cell variant was reduced, as was its attachment capability to gelatin-coated cell culture dishes. Staining of the actin-containing cytoskeleton with fluorescent-labeled phalloidin revealed marked differences in the cytoskeleton architecture between the parent and ET-743-resistant CS-1 cell lines. Comparison of serum-free conditioned medium from both cell lines showed conspicuous differences in the levels of several proteins, including a quartet of high molecular weight proteins (> or =140 kDa). The protein sequences of two of these high molecular weight proteins, present at significantly higher concentrations in conditioned medium obtained from the parent cell line, corresponded to subunits of types I and IV collagen. Analysis of type I collagen alpha1 chain mRNA revealed a significantly lower level in the ET-743-resistant CS-1 cell line. Thus, prolonged exposure to ET-743 may cause changes in cell function through cytoskeleton rearrangement and/or modulation of collagen levels.

Abstract
Integrins are one class of cell surface receptors that have been implicated in the regulation of a diverse set of cellular processes, including cell adhesion, migration, and invasion as well as gene expression, differentiation, and signal transduction. Cellular invasion not only requires the adhesive properties of integrins but also the proteolytic properties of matrix-degrading enzymes, such as the metalloproteinases (MMPs). Previous studies have shown that integrin alphavbeta3 is a receptor for MMP2, localizing its proteinase activity to the cell surface, ultimately leading to site-specific extracellular matrix (ECM) degradation. Here we develop reagents to investigate the possibility of an interplay between MMP9 and integrin alpha5beta1. With the use of EV22 viral studies, the tetrapeptide sequence, LRSG, was shown to be a dimerizing sequence mediating beta1 integrin binding to EV22. The same study also showed that cellular infection could be halted with the use of LRSG-containing peptides. In a later study, in an effort to isolate inhibitors of the MMP family, LRSG sequence was identified as one capable of binding MMP9. Interestingly, MMP9 contains an LRSG sequence, raising the possibility that MMP9 binds the cell surface via beta1 integrins through the dimerizing LRSG motif. We used the LRSG-containing sequence from beta1 integrins as an antigen to generate the monoclonal antibody (MAB) FM155 in the mouse model. MAB FM155 will help identify a cryptic epitope, LRSG, and its role in matrix remodeling as well as tumor growth, cancer cell migration, and angiogenesis.

Abstract
MMP-9 (gelatinase B) is produced in a latent form (pro-MMP-9) that requires activation to achieve catalytic activity. Previously, we showed that MMP-2 (gelatinase A) is an activator of pro-MMP-9 in solution. However, in cultured cells pro-MMP-9 remains in a latent form even in the presence of MMP-2. Since pro-MMP-2 is activated on the cell surface by MT1-MMP in a process that requires TIMP-2, we investigated the role of the MT1-MMP/MMP-2 axis and TIMPs in mediating pro-MMP-9 activation. Full pro-MMP-9 activation was accomplished via a cascade of zymogen activation initiated by MT1-MMP and mediated by MMP-2 in a process that is tightly regulated by TIMPs. We show that TIMP-2 by regulating pro-MMP-2 activation can also act as a positive regulator of pro-MMP-9 activation. Also, activation of pro-MMP-9 by MMP-2 or MMP-3 was more efficient in the presence of purified plasma membrane fractions than activation in a soluble phase or in live cells, suggesting that concentration of pro-MMP-9 in the pericellular space may favor activation and catalytic competence.

Abstract
X-linked Alport syndrome is a progressive renal disease caused by mutations in the COL4A5 gene, which encodes the alpha 5(IV) collagen chain. As an initial step toward gene therapy for Alport syndrome, we report on the expression of recombinant alpha 5(IV) collagen in vitro and in vivo. A full-length cDNA-encoding canine alpha 5(IV) collagen was cloned and expressed in vitro by transfection of HEK293 cells that synthesize the alpha1(IV) and alpha2(IV), but not the alpha 3(IV) to alpha 6(IV) collagen chains. By Northern blotting, an alpha 5(IV) mRNA transcript of 5.2 kb was expressed and the recombinant protein was detected by immunocytochemistry. The chain was secreted into the medium as a 190-kd monomer; no triple helical species were detected. Transfected cells synthesized an extracellular matrix containing the alpha1(IV) and alpha2(IV) chains but the recombinant alpha 5(IV) chain was not incorporated. These findings are consistent with the concept that the alpha 5(IV) chain requires one or more of the alpha 3(IV), alpha 4(IV), or alpha 6(IV) chains for triple helical assembly. In vivo studies were performed in dogs with X-linked Alport syndrome. An adenoviral vector containing the alpha 5(IV) transgene was injected into bladder smooth muscle that lacks both the alpha 5(IV) and alpha 6(IV) chains in these animals. At 5 weeks after injection, there was expression of both the alpha 5(IV) and alpha 6(IV) chains by smooth muscle cells at the injection site in a basement membrane distribution. Thus, this recombinant alpha 5(IV) chain is capable of restoring expression of a second alpha(IV) chain that requires the presence of the alpha 5(IV) chain for incorporation into collagen trimers. This vector will serve as a useful tool to further explore gene therapy for Alport syndrome.

Abstract
Matrix metalloproteinases are important for the turnover of extracellular matrix in tissue. Recent studies have expanded their roles well beyond extracellular matrix degradation - they also cleave many growth factors, cytokines and cell adhesion molecules in the extracellular milieu, modulating their functions irreversibly. In particular, some matrix metalloproteinases that associate with the cell surface have arisen as intriguing regulators of cellular functions, including migration.

Abstract
Membrane type 1 matrix metalloproteinase (MT1-MMP) is a type I transmembrane MMP shown to play a critical role in normal development and in malignant processes. Emerging evidence indicates that MT1-MMP is regulated by a process of ectodomain shedding. Active MT1-MMP undergoes autocatalytic processing on the cell surface, leading to the formation of an inactive 44-kDa fragment and release of the entire catalytic domain. Analysis of the released MT1-MMP forms in various cell types revealed a complex pattern of shedding involving two major fragments of 50 and 18 kDa and two minor species of 56 and 31-35 kDa. Protease inhibitor studies and a catalytically inactive MT1-MMP mutant revealed both autocatalytic (18 kDa) and non-autocatalytic (56, 50, and 31-35 kDa) shedding mechanisms. Purification and sequencing of the 18-kDa fragment indicated that it extends from Tyr(112) to Ala(255). Structural and sequencing data indicate that shedding of the 18-kDa fragment is initiated at the Gly(284)-Gly(285) site, followed by cleavage between the conserved Ala(255) and Ile(256) residues near the conserved methionine turn, a structural feature of the catalytic domain of all MMPs. Consistently, a recombinant 18-kDa fragment had no catalytic activity and did not bind TIMP-2. Thus, autocatalytic shedding evolved as a specific mechanism to terminate MT1-MMP activity on the cell surface by disrupting enzyme integrity at a vital structural site. In contrast, functional data suggest that the non-autocatalytic shedding generates soluble active MT1-MMP species capable of binding TIMP-2. These studies suggest that ectodomain shedding regulates the pericellular and extracellular activities of MT1-MMP through a delicate balance of active and inactive enzyme-soluble fragments.

Abstract
The matrix metalloproteinases (MMPs) constitute a multigene family of over 25 secreted and cell surface enzymes that process or degrade numerous pericellular substrates. Their targets include other proteinases, proteinase inhibitors, clotting factors, chemotactic molecules, latent growth factors, growth factor-binding proteins, cell surface receptors, cell-cell adhesion molecules, and virtually all structural extracellular matrix proteins. Thus MMPs are able to regulate many biologic processes and are closely regulated themselves. We review recent advances that help to explain how MMPs work, how they are controlled, and how they influence biologic behavior. These advances shed light on how the structure and function of the MMPs are related and on how their transcription, secretion, activation, inhibition, localization, and clearance are controlled. MMPs participate in numerous normal and abnormal processes, and there are new insights into the key substrates and mechanisms responsible for regulating some of these processes in vivo. Our knowledge in the field of MMP biology is rapidly expanding, yet we still do not fully understand how these enzymes regulate most processes of development, homeostasis, and disease.

Abstract
Matrix metalloproteinase 9 (MMP-9, also known as gelatinase B or 92-kd Type IV collagenase) is overexpressed in many human and murine cancers. We induced carcinomas in mice carrying a transgene that links the MMP-9 promoter to the reporter ss-galactosidase so that activation of the MMP-9 promoter would be indicated by ss-galactosidase. Mammary carcinomas were induced by mating the MMP-9 promoter reporter transgenic mice with mice carrying a transgene for murine mammary tumor virus promoter linked to polyoma middle T antigen, a transgene that leads to rapid development of mammary tumors in female mice. None of the hyperplastic mammary glands and none of the carcinomas in situ expressed ss-galactosidase. However, all invasive tumors had evidence of ss-galactosidase expression. In addition to the breast carcinomas, a malignant teratoma in a female and a papillary adenocarcinoma in the pelvic region of a male arose and were also ss-galactosidase positive. We also induced skin tumors in the mice with the MMP-9 reporter transgene with 7, 12-dimethylbenz[a]anthracene (DMBA) treatment followed by phorbol 12 myristate 13-acetate (TPA). None of the papillomas or in situ carcinomas showed any ss-galactosidase expression, but expression was seen in invasive carcinoma. Although normal skin epithelial cells did not express ss-galactosidase, we did find staining in a few cells at the duct of the sebaceous gland at the base of the hair follicles. The MMP-9 reporter transgene did not lead to expression in the alveolar macrophages, confirming that additional upstream sequences are required for expression in macrophages. These experiments have revealed that MMP-9 promoter activity is induced coincident with invasion during tumor progression. Furthermore, this indicates that the more proximal upstream elements of the promoter are sufficient for MMP-9 transcription during tumor progression.

Abstract
Primary cultures of psoriatic keratinocytes proliferated at a higher rate and produced lower amounts of matrix metalloproteinase 9 than normal keratinocytes cultured under similar conditions. Sup- plementation of psoriatic keratinocyte cell culture medium with batimastat or the use of a matrix metalloproteinase 9 blocking antibody further stimulated psoriatic keratinocyte growth. An increase in intracellular ceramide level enhanced matrix metalloproteinase 9 production and inhibited cell proliferation in parallel. Whether cells were treated with sphingomyelinase or not, however, conditioned media from psoriatic keratinocytes contained higher levels of tissue inhibitor of metalloproteinase-1 compared with matrix metalloproteinase 9 and secreted only the proenzyme form. Pro-matrix metalloproteinase 9, as well as active matrix metalloproteinase 9, was identified in membrane preparations of psoriatic keratinocytes, and enzyme amounts were greatly elevated following sphingomyelinase action. As (i) tissue inhibitor of metalloproteinase-1 antibody nearly totally abrogated keratinocyte growth and (ii) complexes of tissue inhibitor of metalloproteinase-1 and matrix metalloproteinase 9 were recovered in membrane extracts of sphingomyelinase-treated psoriatic keratinocytes, we postulate that an increased level of cell-associated matrix metalloproteinase 9 might compete for tissue inhibitor of metalloproteinase-1 binding to its receptor. As a consequence, the increased levels of matrix metalloproteinase 9 will decrease keratinocyte growth.
