Schmitt, Élise. "Hsp70 : une cible dans la thérapie anti-cancéreuse". Dijon, 2006. http://www.theses.fr/2006DIJOMU13.
Testo completoHSP70 is a heat shock protein overexpressed in several cancer cells. It prevents apoptosis, thereby increasing the survival of cells exposed to a wide range of lethal stimuli. These protective functions of HSP70 involve its interaction with and neutralization of Apaf-1, implicated in caspase activation, and AIF, involved in caspase-independent cell death. We have shown that a peptide containing the AIF sequence involved in its interaction with HSP70, binds to and neutralizes HSP70 in the cytosol, thereby sensitizing cancer cells to apoptosis induced by a variety of death stimuli. The expression of ADD70 in tumor cells decreases their tumorigenicity in syngeneic animals without affecting their growth in immunodeficient animals. In addition, ADD70 sensitizes rat colon cancer cells and mouse melanoma cells to the chemotherapeutic agent cisplatin. Altogether, these data indicate the potential interest of targeting the HSP70 interaction with AIF for cancer therapy
Frutoso, Marie. "RLI et agonistes, enjeux pour la thérapie anti-cancéreuse". Thesis, Nantes, 2017. http://www.theses.fr/2017NANT4005.
Testo completoIL-15 is an of interest cytokine in the immunotherapy field as it participates to the regulation of the activation and the proliferation of NK and CD8 T cells that are essential for tumor eradication. In this study, we first investigated the anti-‐tumor potential of an IL15 agonist called RLI, fused to the Fc fragment of a human IgG1 in order to improve its half-‐life in vivo (Fc-‐RLI). We have shown that, this prolonged half-life allows an amplified proliferation of the immune cells. Moreover, we have shown that this quantitative augmentation of immune cells didn’t improve the therapeutic outcome of the RLI alone. We have also indicated that the dosing regimen needs to be adapted to the used tumor model. In a second part we have evaluated the NK and CD8 T cells response to a re-‐stimulation model using IL-2, IL-15 or IL-15’s agonist. We have exposed a hypo-‐responsive state of NK cells during the second stimulation and have established CD8 T cells as responsible for this defect

Testo completoA novel hybrid nanosystem, resulting from the encapsulation of iron oxid nanoparticles into stercally stabilised phospholipidic vesicles, has been realised and characterised. These socalled magnetoliposomes, revealed as excellent MRI contrast agents, could be guided towards a tumor tissue or a cerebral hemisphere thanks to an external magnetic gradient

Testo completoIn the frame of this PhD project, smart superparamagnetic nanoparticles (SPIONs) have been developed for a further use as a drug platform for cancer therapy. These nanoparticles of core / shell type are obtained from the functionalization of a core based on Fe3-δO4 by a co- polymer obtained from the surface-initiated polymerization of a mixture xMEO2MA and yOEGMA (x + y = 1). Once their structures and their colloidal behavior in water and in-vitro perfectly characterized as well as the demonstration of their thermo-responsive properties, studies of encapsulation and release of an anti-cancer drug, the doxorubicin (DOX) at physiological temperatures were successfully obtained. In-vitro studies showed the non- cytotoxicity of the nanoparticles, but when the cancer cells were in contact the DOX-loaded NPs, the cytotoxicity was increased. To induce the targeting of ovarian cancer (SKOV3 cells) and the enhancement of the internalization of nanoparticles in cells, we have functionalized the previous nanoparticles with folic acid as these last cells over-express receptors that bind folate α (FR-α ). The combination of different macroscopic and nanometric scale characterization techniques allowed us to conclude that our systems are capable of encapsulating DOX, releasing it in a specific manner and at a controlled rate and that they exhibit hyperthermia properties. We have then contributed to successfully develop new third generation vectors for cancer therapy

Testo completoCancer therapies (radiotherapy, chemotherapy, etc.), although very effective, have side effects. Today, photodynamic therapy (PDT) represents a real option in the world of cancer therapy. Under the action of light, a photo-activatable molecule called a photosensitizer is able to transfer its energy to the surrounding oxygen to induce the formation of reactive oxygen species capable of destroying cancer cells. PDT treatment of some primary and metastatic tumors has shown very encouraging results. The limitations of PDT are the low penetration of light into the tissues and the lack of selectivity of most photosensitizers currently used in the clinic.A relatively new approach, called X-PDT, is to use X-rays instead of UV-visible light to overcome the shallow penetration depth of visible light into tissue. Upon exposure to ionizing X-rays, nanoscintillators transfer their energy to PSs, which are then activated and can initiate PDT action. In this thesis, we have developed nanoscintillators based on AGuIX nanoparticles containing Gadolinium or Terbium chelates. Rose Bengal (RB) was covalently coupled to AGuIX. To specifically target NRP-1, a membrane receptor overexpressed on endothelial cells, a peptide was also coupled (DKPPR or another sequence).The photophysical study of these new nanoparticles allowed us to confirm that there is an energy transfer between the chelated lanthanide and the Rose Bengal under illumination or excitation by X-rays. We have shown that the Rose Bengal produces oxygen singlet capable of destroying cancer cells. The peptide, even coupled to the nanoparticles, retains its ability to target NRP-1

Testo completoThe aim of my study was about physio-pathological angiogenesis and its pharmacological regulation by chemicals drugs or by gene therapy. Angiogenesis is the formation of new blood vessels from pre-existing ones. It is a physiological process tightly regulated, which occurs for example during healing. However, angiogenesis is also critically involved in several pathologies, such as cancer. Indeed, angiogenesis is implicated in tumor growth as well as dissemination of metastases. In addition, angiogenesis is also involved in atherosclerotic plaque development and weakening, responsible for acute vascular ischemic events. The first part of my work was a study of the effects of two pharmacological drugs on angiogenesis. Fenofibrate is a drug currently used in atherosclerotic patients to reduce triglycerides levels. Its clinical benefits seem to be higher than those expected for its activity on lipid mefer genes coding for anti-angiogenic molecules : tissue inhibitor of matrix metalloproteinase type-2 (TIMP-2) and angiostatin. We have also tested a new strategy to inhibit the aggressiveness of cancerous cells and tumoral angiogenesis, using RNA interference, to specifically inhibit GTPases RhoA and RhoC, involved in cellular proliferation and invasivity. This study shows the interest to use SiRNA in therapy in vivo and the importance of the specificity in the inhibition of a therapeutic target. This is a fundamental and physiopathologic work on angiogenesis and its pharmacological regulation, in classical therapeutic and in gene therapy, particularly in vascular and cancerous pathologies

Testo completoDependence receptors share the common property of inducing two types of signaling according to their ligand availability. In presence of their ligand, they induce a positive signal allowing cell survival whereas in its absence, they induce cell death by apoptosis. These receptors thus create cellular states of dependence on the ligands. Dependence receptors dual functionality plays a major role both during the embryonic development and in the regulation of tissue homeostasis in adult. Indeed, apoptosis induced by dependence receptors would be a safeguard mechanism that restricts tumor escape by eliminating cells that would proliferate or migrate in settings of ligand limited availability. A potential selective advantage for a tumor cell would then be to loose this apoptotic signaling, either through a loss of the receptor apoptotic function or through an autocrine gain of the ligand expression. Dependence receptors DCC (Deleted in Colorectal Cancer) and UNC5 (Uncoordinated-5 homolog) that share the same ligand, netrin-1, thus behave as tumor suppressors which expression is frequently decreased in many types of cancers. Here we show that netrin-1 is overexpressed in a significant fraction of Non Small Cell Lung Cancers, aggressive neuroblastoma, and colorectal cancers associated with inflammatory diseases which confers tumor cells a selective advantage by blocking DCC and UNC5-induced apoptosis. During developmental angiogenesis, we also show that netrin-1 promotes endothelial cells survival by blocking UNC5B-induced cell death. Thus, inhibiting the interaction between netrin-1 and its receptors could represent an innovative anti-tumor therapeutic strategy that would restore apoptosis both in tumor cells and in vessels that feed the tumor. This is the reason why we also got interested in Sonic Hedgehog (SHH) ligand, that is overexpressed in many different types of cancers, and that binds the dependence receptor Patched1 (PTC1) but also other transmembrane receptors such as CDO (Cell adhesion molecule Downregulated by Oncogenes). We show here that CDO is a new dependence receptor of SHH, and that this relationship is involved in both developmental and tumorigenic processes. Thus, this work gives a more precise view of the dependence receptors concept and opens the way on the conception of new anti-tumor therapies that would target the interaction between dependence receptors and their ligands

Testo completoPhosphoantigen-stimulated human TCR-Vgamma9Vdelta2 gamma eltaT lymphocytes exert a potent antitumor cytolysis. Their activity is currently assessed in several clinical trials of cancer immunotherapies. Some cancers and their microenvironment produce suppressive molecules however, which might contribute to tumor escape. This PhD thesis deals with the contribution of TGF-beta to cancer immunoevasion, and means to avoid it. We show that the combination of therapeutic monoclonal antibodies to lymphocytes activated TCR-Vgamma9Vdelta2 gamma delta T cells improves anti-tumoral immunologically-mediated killing and may counter TGF-beta-mediated immunosuppression. We illustrate this concept of targeted therapeutic combination in a murine model of Her2/neu mammary carcinoma xenografts. Together, our results demonstrate the potential of such therapeutic strategies in cancer
