Texte intégralMetastases are responsible for 90% of cancer-related deaths justifying the current cancer research's substantial part dedicated to study their formation's mechanisms. It has been recently demonstrated that clusters (or aggregates) of circulating tumor cells (CTCs) identified in patient's blood samples have a far higher metastatic potential than isolated circulating tumor cells. It also has been shown that their detection is correlated with a poor prognosis for patients suffering from epithelial cancers. These observations open up promising diagnostic and therapeutic perspectives but that still requires further investigation on the mechanisms of clusters formation. In this context our laboratory developed an in vitro semi-automated assay based on video microscopy enabling the study of mechanisms involved in tumor cell anchorage-independent clustering. This assay allowed to demonstrate the involvement of adherent junction protein E-cadherin and desmosomal junction proteins DSG2 and DSC2 during tumor cell clustering. The aim of my work was to investigate epithelial intercellular junction's proteins involvement in tumor cell aggregation in anchorage-independent conditions and to search for new regulators. In the first instance I explored and demonstrated the role of communicating junctions (or gap junctions) and P-cadherin in tumor cell aggregation of breast and colorectal cancer cell lines. In the second part, I developed a strategy based on tumor cell lines classification depending on their characteristics of the aggregation process. With the aim of determining the parameters of this classification, I examined aggregation abilities of 28 tumor cell lines derived from epithelial cancers. This study provides evidence for a high variability during this process and allows defining cell lines categories integrating both aggregation process dynamic aspects and aggregates structure. The combination of this classification with current available expression data could lead to the identification of original new aggregation regulators. Together, these results have underscored new anchorage-independent tumor cell aggregation regulators and a wide range of behaviors of different tumor cell lines observed. Our work provides opportunities into a better understanding of involved mechanisms, towards an application to study circulating tumor cells from patients and also a therapeutic targeting of these clusters

Texte intégralCancer is the second cause of death worldwide. Recent advance in cancer treatments involved the identification of cancer biomarkers and the development of efficient therapeutic products able to specifically recognize them. This new class of products has the ability to specifically target tumor cells, with the major advantages to decrease or abolish treatments side effects and relapses of the disease. Unfortunately, a certain number of patients do not respond to those treatments lacking the expression of those biomarkers on their tumor. This project aims at developing new targeted therapies by exploiting a new class of cancer biomarkers, which would potentially extend the therapeutics options against cancer

Texte intégralLa morte cellulare e l’effetto bystander rappresentano degli elementi decisivi per l’efficacia della terapia antitumorale nonchè per la modulazione della risposta immunitaria contro il cancro. Per “effetto bystander” si intende il processo per il quale le cellule non soggette a determinati trattamenti farmacologici subiscono indirettamente gli effetti terapeutici, siano essi positivi o negativi, risultanti dal trattamento esclusivo delle cellule vicine. Nonostante siano state proposte diverse molecole e vie di segnalazione coinvolte nell’effetto bystander, i messaggeri molecolari essenziali ed i meccanismi che sottendono alla propagazione dei segnali di morte non sono ancora noti. Diversi studi suggeriscono un coinvolgimento dell’ossido nitrico (NO) e delle specie reattive dell’azoto (RNS) nell’effetto bystander tuttavia, il loro ruolo nel processo non è tuttora totalmente chiaro, considerato che essi possono sia inibire che sostenere la progressione del tumore. Inoltre, i metodi tradizionalmente usati per lo studio dell’ossido nitrico non riflettono necessariamente la produzione di NO in tempo reale nè consentono studi su complesse masse tumorali tridimensionali. L’obiettivo principale di questo studio è stato quello di individuare e caratterizzare i segnali cellulari responsabili dell’effetto bystander all’interno del microambiente tumorale, rivolgendo particolare attenzione all’NO. A questo scopo, abbiamo utilizzato delle tecniche di microscopia intravitale, avvalendoci di una nuova sonda fluorescente per l’NO (CuFL) e del modello sperimentale delle camerette dorsali impiantate su topi affetti da tumore e sottoposti a terapia fotodinamica (PDT). Da questo studio è emerso che l’effetto bystander indotto dalla terapia fotodinamica è associato alla generazione all’interno della massa neoplastica di onde molto rapide di segnali di NO e di Ca2+. Questi eventi avallano l’ipotesi che l’attività delle isoforme costitutive dell’enzima NOS possa esercitare un ruolo cruciale nella diffusione delle risposte bystander e nella trasmissione dei segnali di morte. Questo lavoro inoltre ci ha consentito di dimostrare che la terapia fotodinamica è in grado di indurre l’apoptosi delle cellule vicine non trattate (bystander) attraverso i meccanismi di comunicazione intercellulare mediati dalle giunzioni comunicanti. Infine, i risultati ottenuti hanno fornito la prima evidenza diretta della partecipazione dell’NO all’effetto bystander all’interno di una massa tumorale tridimensionale e corroborano efficacemente l’ipotesi che le giunzioni comunicanti formate da connesine siano essenziali per garantire la propagazione dei segnali di morte osservati nell’effetto bystander.

Texte intégralCancer gene therapy requires the use of an effective suicide gene and the specific targeting of cancer cells. In my PhD work, I have first characterized a new potential suicide gene derived from human deoxycytidine kinase (dCK): M36. Compared to dCK, M36 improves sensitization of certain cancer cells to treatment with chemotherapeutic compounds as gemcitabine and AraC. These results are particularly encouraging for the elimination of cancer cells resistant to the treatment because of a defect with dCK. In a second part, I have worked at the proof of concept that a modified HIV envelope can allow specific targeting of cancer cells by lentiviral vectors. During this work, I have generated a CD4i envelope with a strongly diminished natural tropism and that carries a motif known to bind the model cell surface cancer marker HER2. This envelope constitutes a good starting material to be improved by evolution in cell culture to obtain specific targeting of HER2+ cells
Poupard, Nicolas. « Conception de polysaccharides sulfatés inhibiteurs de l’héparanase pour le traitement de l’angiogénèse tumorale ». Thesis, La Rochelle, 2017. http://www.theses.fr/2017LAROS011/document.
Texte intégralTumor angiogenesis is defined by the spouting of new blood vessels from preexisting ones in order to sustain and amplify the tumor development. This crucial step is associated with poor prognosis for patients and it’s inhibition is therefore considered as a primising way to treat cancer. Among several actors participating in the angiogenesis process, the degradative enzyme heparanase is active in the tumor microenvironment of many cancers. The work presented in this thesis aim to develop specific heparanase inhibitors using sulfated polysaccharides for the treatment of tumor angiogenesis. The first part of this work is dedicated to the conception of low molecular weights sulfated polysaccharides obtainable from animal source (Héparine, Chondroïtine sulfate), algal source (Fucoidan, Carrageenan-λ-ι-κ) and bacterial source (dextran sulfate). To do so, we used a depolymeriation process based on free radicals associated to ultrasonic waves developed in 2013 in the laboratory. This depolymerization method was then coupled with a chemical process called glycol-split. The produced compounds were evaluated for their capacity to inhibit heparanase and blood coagulation. This screening phase lead to the identification of a low molecular weight compound produced from λ-carrageenan endowed with a strong heparanase inhibition power and a low impact on the blood coagulation. The second part of this work was then focused on the evaluation of the anti-angiogenic properties of our best heparanase inhibitors. To do so, we first evaluated the role of hypoxia and lack of nutrients on the heparanase production from breast cancer cell lines. In these higly stressful conditions, we observed that the MCF-7 cell line secreted a huge amount of heparanase. 3D Matrigel angiogenesis network formation using Hsk-MEC microvascular cells in the presence of MCF-7 heparanase rich supernatant showed a strong angiogenesis stimulation. Same tests realized in the presence of heparanase inhibitors showed an angiogenesis inhibition power that seemed correlated with heparanase inhibition

Texte intégralPautu, Vincent. « Steath and pH-sensitive lipid nanocapsules : targeting the tumor microenvironment of melanoma ». Thesis, Angers, 2018. http://www.theses.fr/2018ANGE0042.
Texte intégralTumor acidity has been shown to play a major role in resistance to chemotherapy. The use of nanomedicines, as lipid nanocapsules (LNC), allows to protect drugs from this acidic environment. They can also improve the biodistribution of therapeutics and to target the tumor environment. The aim of this thesis concerns the evaluation and characterization of stealth and pH-sensitive LNC in the context of melanoma. Firstly, these works consisted in characterizing the vascularization of human and mice melanoma. These studies allowed to compare different tumors (density, size and structure), and determine if the used of nanocarrier is suitable in the context of melanoma.The second part of this thesis described the development and the characterization of new copolymers, combining stealth and pH-sensitive properties. These copolymers, composed of Nvinylpyrrolidone(NVP) and vinylimidazole, were synthesized by RAFT polymerization and were post in sertedonto LNC surface. These modifications allowed to obtain charge reversal nanocarriers, leading to increase their melanoma cell uptake underacid pH. Finally, biodistribution of these modified nanoparticles was studied in vivo and highlighted the interest of NVP in the development of stealth nanocarriers. To conclude, the developed copolymers able to extend nanocarrier circulation time and to provide pH-responsive properties which should increase the tumor internalization of LNC invivo and potentiate the effect of anticancer drugs

Texte intégralThe cancer research is nowadays interested in targeting therapies. In this context, nucleolin and nucleophosmin are proteins highly involved in tumor growth and angiogenesis and over-expressed in activated endothelial and tumor cells. So, they appear as very promising targets. The pseudopeptide HB-19 binds to cell surface-expressed nucleolin, inhibits different tumor cell growth and induces cell death by apoptosis. Furthermore, it inhibits, in vitro and in vivo, several steps of angiogenesis. These two activities lead, in vivo, to the suppression of tumor growth and angiogenesis in several mice models. In order to improve the activities observed with HB-19, new compounds derived from HB-19 were synthesized. So, NucAnt 6L (N6L) show 5 to 10 fold stronger anti-tumoral activity than HB- 19 depending of the model. Study of their action mechanism allowed us to identify two new receptors: nucleophosmin and heparan sulfates. The importance of TIMP-3 in anti-metastatic activity has also been highlighted. Finally, no toxicity has been observed in mice treated with N6L which can easily industrially be synthesized. N6L appears to be a promising compound for anti-cancer therapies
TULLIO, CHIARA. « Development of an effective tumor-targeted contrast agent for magnetic resonance imaging based on Mn/H-ferritin nanocomplexes ». Doctoral thesis, Università degli Studi di Milano-Bicocca, 2021. http://hdl.handle.net/10281/307662.
Texte intégralMagnetic resonance imaging is one of the most sophisticated diagnostic tools in clinic. Contrast agents (CAs) may be exploited to afford much clearer images of detectable organs and to reduce the risk of misdiagnosis, due to the limited sensitivity of the technique. Actually, only a few gadolinium-based CAs are approved for clinical use. Nevertheless, concerns over their toxicity remain and their administration is approved only under strict control. In the present study it is reported the synthesis and validation of a novel manganese-based CA, Mn@HFn-RT. Manganese is an endogenous paramagnetic metal able to produce a positive contrast like gadolinium, however it is estimated to cause lower toxicity for human body. MN ions have been efficiently loaded inside the shell of a recombinant human protein called H-ferritin that is recognized by cells overexpressing TfR1, including the majority of cancer cell. Mn@HFn-RT was characterized, showing excellent colloidal stability, superior relaxivity and good safety profile. From in vitro experiments it was possible to confirm the ability of Mn@HFn-RT to efficiently target cancer cells and thus favor the detection of the tumor region in a breast cancer in vivo model with very low metal dosages and showing rapid clearance. Mn@HFn-RT looks a promising CA candidate to be developed for MRI.
