Abstract:
The epithelial restricted αvβ6 integrin is known to have minimal expression in healthy tissue and to be upregulated in cancer and healing wounds. This thesis explores the role of αvβ6 in cancer and tests the hypothesis that αvβ6 has a prognostic and therapeutic utility in cancer. Using immunohistochemistry, increased αvβ6 expression was found in nonmelanoma skin cancers (NMSC), particularly in morphoeic type basal cell carcinoma. In cell culture experiments, αvβ6 was found to activate TGF-β and promote myofibroblast differentiation, producing a tumour stroma rich in smooth muscle actin (SMA).

Abstract:
Pancreatic cancer is often referred to as the “silent killer“ due to the asymptomatic nature of the disease in the early stages and the extremely poor prognosis overall. The average one-year survival rate for PDAC patients is 24% (American Cancer Society, facts and figures, 2010), decreasing to 5%-6% over 5 years (WHO report, Pancreatic cancer, 2010). Only 20% of patients are suitable for surgical resection at the time of diagnosis and treatment options available to PDAC patients have not improved significantly over the past few decades. Thus novel therapeutic approaches are essential to treat

Abstract:
Alterations to the tumour microenvironment is a common feature of many cancers, including breast cancer, and there is increasing evidence that alterations to the microenvironment, including; increased integrin expression, ECM deposition and protease activity, promote cancer progression. Most invasive breast cancers arise from a preinvasive stage, ductal carcinoma in situ (DCIS). Previous work in our laboratory has shown the microenvironment of DCIS is altered, such that myoepithelial cells (MECs) switch to a tumour-promoting phenotype, associated with upregulation of integrin αvβ6 and fibronec

Abstract:
Abstract Matrix metalloproteinases, MMPs, are a family of enzymes capable of modulating connective tissue components. The expression of several MMPs is increased in oral squamous cell carcinomas (OSCCs). They are assumed to have an important role in the development and progression of OSCCs. However, the exact role and mechanism of the regulation of MMPs in malignant transformation are still largely unknown. In this study, tumour-associated trypsin-2 (TAT-2) was detected in OSCC tissue sections, and its role in MMP-2 and -9 regulation in carcinoma cells was evaluated. The TAT-2 gene was trans

Abstract:
La résection chirurgicale constitue le traitement de première intention des cancers de la tête et du cou (HNSCC). La berge peropératoire est un facteur de pronostic majeur pour la survie globale des patients. Actuellement, il existe peu d’outils pour discriminer de manière fiable et en temps réel le tissu tumoral du tissu sain. La chirurgie guidée par la fluorescence (FGS) proche infrarouge (NIR) est une méthode d’imagerie utilisant le marquage fluorescent des tissus tumoraux afin de fournir une image de contraste augmentée. Le but de ces travaux est l’étude de la distribution de Quantum Dots

O TA está envolvido na regulação da energia corporal, sintetizando e secretando substâncias denominadas adipocinas, dentre elas a adiponectina e leptina. A adiponectina está relacionada ao aumento da sensibilidade à insulina, enquanto a leptina está envol

Abstract:
Invasion and metastasis of cancer is the leading cause of increased mortality. In addition, haematological malignancies (leukaemia and lymphoma) are a significant cause of morbidity and mortality in both children and adults. Therefore, new treatments which will inhibit cancer progression are required. Integrin adhesion receptors, particularly the RGD-binding integrin subfamily comprising αvβ3, αvβ5, αvβ6, αvβ8, αllbβ3, α5β1, α8β1 and αvβ1 are related to progress and spread of cancer and poor prognosis. Because of the importance of integrin biology in the regulation of cancer dissemination, the
