Texte intégral@Melanoma progression involves proteolytic cascades including matrix metalloproteinases (MMPs) and plasminogen activation system. These proteolytic cascades can both be controlled by peptides derived from basement membranes macromolecules, matrikins. We studied the anti-tumor and anti-angiogenic properties of various matrikins derived from collagens XIX and IV. NC1[a1(XIX)] domain exhibits strong anti-angiogenic and anti-tumor activities in vitro and in an experimental in vivo mouse melanoma model, therefore, it constitutes a new matrikin. The YSNSG cyclopeptide, a conformational analogous of the native NC1[a3(IV)185-191] peptide, reduces in vitro human melanoma cell proliferation and invasion, by inhibiting proteolytic cascades involving MMPs and plasmin. It exhibits a potent anti-angiogenic activity, by inducing a non-migratory phenotype of endothelial cells. In vivo, its anti-tumor activity is increased versus the native peptide, suggesting a better bioavailability and/or stability. Overexpression of NC1[a3(IV)] and NC1[a4(IV)] domains by melanoma cells strongly reduces their proliferative and invasive properties. We developed a new therapeutic strategy based on the in vivo matrikin overexpression in mice, induced by cDNA electrotransfer. In the model, tumor growth is strongly inhibited and animal survival largely increased. Matrikins derived from basement membrane collagens, especially NC1[a3(IV)] and NC1[a4(IV)] domains, represent powerful anticancer agents, able to limit melanoma progression

Texte intégralWith 47582 new cases in 2023, colorectal cancer (CRC) is the second most common cause of cancer-related death in France, accounting for almost 12% of all deaths, particularly in people over 65. The 5-year survival rate is estimated at 63%. In over 80% of cases, colon cancer stems from a benign tumour called an adenomatous polyp, which slowly evolves into a malignant tumour. Current therapies have numerous side effects. Moreover, not all patients respond to them, and they can induce resistance phenomena. The search for new therapeutic strategies to limit CRC progression therefore remains a major challenge. The non-collagenous NC1 domain of the α4 chain of type IV collagen, a 230 amino acid sequence also known as Tetrastatin, has been shown to inhibit melanoma progression. The QS-13 peptide, identified as the minimal active sequence of Tetrastatin, mimics its anti-tumor effects and possesses anti-angiogenic activity, mediated by its interaction with αvβ3 and α5β1 integrins. This peptide comprises 13 amino acids (QKISRCQVCVKYS) and features a disulfide bridge between cysteine residues that spontaneously forms in solution. However, the QS-13 peptide has limited solubility in aqueous media, requiring prior dissolution in DMSO, which is an impediment to its therapeutic use. Using bioinformatics tools, we demonstrated that DMSO could facilitate disulfide bridge formation but was not strictly necessary. Hydrophobic amino acid substitutions were made to improve the solubility of the QS-13 peptide. The interaction of the new designed peptides with αvβ3 and α5β1 integrins was analyzed in silico using molecular docking approaches. All these peptides were able to fix integrins close to the RGD binding site, potentially enabling them to compete with ligands such as fibronectin, as well as FGF1, FGF2, IGF1 and IGF2, and to modify FAK/PI3K/Akt signaling pathway. Among the peptides studied, we selected QS-13-3, the peptide with the highest stability index, a high hydropathy index and only 2 substituted amino acids. The results confirmed that the substitutions did not alter peptide biological efficacy. It was reported that NC1 domains of collagen IV show structural analogies with TIMP-2, a tissue inhibitor of matrix metalloproteinases (MMPs). We therefore focused on the potential interactions of QS-13 and QS-13-3 peptides with these MMPs. Using bioinformatics tools (in silico), we showed that they could bind directly to MMP-2 and MMP-14, and then demonstrated a dose-dependent inhibition of the catalytic activity of both MMPs. Finally, the results obtained on the effects of QS-13 and QS-13-3 peptides on intercellular communication via extracellular vesicles, as well as the effects observed in various in vitro, ex vivo and in in vivo models, confirmed the potential therapeutic efficacy of QS-13 and QS-13-3 peptides in limiting CRC progression and tumor angiogenesis

Texte intégralMelanoma is the most invasive cutaneous cancer. During tumor invasion and metastatic dissemination, tumor cells degrade the extracellular matrix by secretion of proteases such as MMPs. During matrix proteolysis, fragments of the extracellular matrix with anti-tumor and/or anti-angiogenic activities, called matrikines, are released and modulate tumor growth. Many matrikines derived from basement membrane collagens are able to inhibit tumor progression. We studied the anti-tumor properties of the domain NC1 α4 (IV), named tetrastatin, both in vitro and in vivo in a human melanoma model. Tetrastatin induces inhibition of proliferation and invasion of melanoma cells in vitro. This inhibition of proliferation is correlated to a cell cycle delay in G1/S phase when cells are incubated with tetrastatin. The inhibition of invasion could be due, at least partly, to the inhibition of MMP-14 active form and modification of its cellular distribution, with a loss of the migratory phenotype in the presence of tetrastatin. In vivo, tetrastatin overexpression induces a strong inhibition of tumor growth, in a human melanoma xenograft model in nude mice. We also identified integrin αvβ3 as a potential receptor of tetrastatin. Finally, the study of the anti-proliferative and anti-invasive properties of the UACC 903 cells in the presence of different peptides allows us to better identify the sequence responsible of the anti-tumor activity. In conclusion, tetrastatin is a new potent anti-tumor matrikine capable of limiting melanoma progression

Texte intégralType XIX collagen is a minor collagen localized in specialized basement membranes. Our laboratory demonstrated that its NC1(XIX) domain is a matrikine which presents anti-tumor and anti-angiogenic properties. The aim of this work was to study the mechanisms leading to this anti-tumor activity.During tumor invasion, cancer cells degrade basement membrane components leading to anti-tumor matrikine release. First, we demonstrated that plasmin, a key enzyme in tumor invasion, cleaved the C-terminal domain of type XIX collagen, in vitro and ex vivo, and released a peptide with a sequence in close vicinity to the NC1(XIX) peptide. Molecular modeling studies showed that NC1(XIX) peptide and the released fragment adopted locally the same type I β-turn conformation. Then, we showed that this peptide inhibited migration of tumor cells in vitro and tumor growth in vivo. This study demonstrated that collagen XIX is a novel proteolytic substrate for plasmin. Such release may constitute a defense of the organism against tumor invasion.The main matrikine receptors belong to the integrin family. In a model of human melanoma cells (SK-MEL-28), we characterized αvβ3 integrin as NC1(XIX) peptide receptor. We also demonstrated that the binding of NC1(XIX) peptide on αvβ3 integrin induced a decrease in phosphorylation of FAK tyrosine 861 residue, PI3K p85 tyrosine 458, PDK1 serine 241,Akt threonine 308 and serine 473, mTOR serine 2448 and 2481, and GSK3β serine 9. The decreased activity of this FAK / PI3K / Akt / mTOR pathway, heavily involved in melanoma signal transduction, could explain, at least in part, the antitumor effects of NC1(XIX) peptide.Meanwhile, this work allowed us to develop PCR, Western blot and ELISA to quantify the expression of collagen XIX and its NC1(XIX) peptide. These steps were required for clinical applications
