Research lines Expression analysis and functional elucidation of connexins and pannexins in relation to human cancer progression and malignancy. Connexins and pannexins are structural units of gap junctions permitting direct intercellular communication. Deregulation of gap junctions is a frequent feature of carcinogenesis. We are characterizing the expression level of a variety of connexins and pannexins in primary and metastatic human tumours. In vitro we are studying how these proteins affect features related to the degree of malignancy such as migration, invasion and resistance to hypoxia. In connexin-deficient cell lines we are over-expressing specific wild-type or truncated forms of connexins and pannexins using retroviral constructs recently generated. In cell lines expressing high levels of specific connexins, we knockdown the expression levels using established lentiviral shRNA strategies. We aim to correlate connexin expression and cell communication with malignancy using a variety of well characterized assays with particular focus on colony formation, migration, invasion, epithelial-to-mesenchymal transition, changes in tumour stem cell populations, and hypoxia and drug resistance. The aim of the study is to: 1) Identify any significant correlation between the expression of various gap junction proteins and the malignancy, prognosis, chemo-resistance and overall survival in a variety of cancers 2) Gain mechanistic insight and identify direct functional roles of connexins and pannexins during tumour progression.
