Towards participatory political theology: democratic consolidation in Southeastern Europe and the role of Eastern Christianity in the process

This thesis defends the position that the Eastern Orthodoxy has the potential to develop, on the basis of its core concepts and doctrines, a new political theology that is participatory, personalist and universalist. This participatory political theology, as I name it, endorses modern democracy and the values of civic engagement. It enhances the process of democracy-building and consolidation in the SEE countries through cultivating the ethos of participation and concern with the common good among and the recognition of the dignity and freedom of the person. This political-theological model is developed while analyzing critically the traditional models of church-state relations (the symphonia model corresponding to the medieval empire and the Christian nation model corresponding to the nation-state) as being instrumentalized to serve the political goals of non-democratic regimes. The participatory political-theological model is seen as corresponding to the conditions of the constitutional democratic state. The research is justified by the fact the Eastern Orthodoxy has been a dominant religiouscultural force in the European South East for centuries, thus playing a significant role in the process of creation of the medieval and modern statehood of the SEE countries. The analysis employs comparative constitutional perspectives on democratic transition and consolidation in the SEE region with the theoretical approaches of political theology and Eastern Orthodox theology. The conceptual basis for the political-theological synthesis is found in the concept and doctrines of the Eastern Orthodoxy (theosis and synergy, ecclesia and Eucharist, conciliarity and catholicity, economy and eschatology) which emphasize the participatory, personalist and communal dimensions of the Orthodox faith and practice. The paradigms of revealing the political-theological potential of these concepts are the Eucharistic ecclesiology and the concept of divine-human communion as defining the body of Orthodox theology. The thesis argues that with its ethos of openness and engagement the participatory political theology presupposes political systems that are democratic, inclusive, and participatory, respecting the rights and the dignity of the person. The political theology developed here calls for a transformation and change of democratic systems towards better realization of their personalist and participatory commitments. In the context of the SEE countries the participatory political theology addresses the challenges posed by alternative authoritarian political theologies practiced in neighboring regions.

Investigating the role of N-WASP in the development of colorectal cancer

Colorectal cancer (CRC) is the second most common cancer in Europe, with the second highest mortality rate. Although prognosis is improving, survival rates remain poor for those presenting with the most advanced stages of the disease. There is therefore a need for improved early diagnosis and thus a greater understanding of the early stages of the development of colorectal tumours is desirable. Additionally, as most deaths in colorectal cancer are due to advanced metastatic disease, it is of great interest to explore any potential mechanisms by which metastatic disease can be inhibited. N-WASP is a ubiquitously expressed protein with multiple intracellular roles including actin regulation and maintaining stability of epithelial cell-cell junctions. Through its role as an actin regulator, it has been implicated in the processes of invasion and metastasis of multiple cancer types. Its role in the development and progression of colorectal cancer however has not been fully explored. This thesis will present a series of in vitro and in vivo studies that were carried out with the aim of answering the following questions: • Does N-Wasp have a role in normal intestinal homeostasis? • Does N-Wasp knockout affect the development of tumours in a mouse model of intestinal tumourigenesis? • Does N-Wasp knockout affect the invasive properties of intestinal cancer in vitro? • Does N-WASP correlate with prognosis or other indicators in human colorectal cancer TMAs? Findings from the in vivo experiments, using an inducible, gut-specific knockout model, have uncovered potential roles for N-Wasp in regulating differentiation and migration of intestinal epithelial cells. Although it had no effect in short term models of intestinal hyperproliferation, N-Wasp knockout increased tumour burden and decreased survival in an established in vivo model of intestinal tumourigenesis, in which there is heterozygous loss of Apc (Apcfl/+). No effect was seen on tumour development or survival when additional N-WASP knockout was introduced into a more rapid model, with heterozygous loss of Apc and mutation of Kras (Apcfl/+ KrasG12D/+). N-WASP expression in human colorectal cancer was assessed using immunohistochemical staining of two tissue microarrays. Low levels of N-WASP expression were found to be associated with presence of MMR deficiency. There was no statistically significant difference in overall or cancer specific survival based on N-WASP expression. Collectively, the data presented here suggest a previously unreported role for N-WASP in regulation of intestinal epithelial differentiation and indicate that it may act as a tumour suppressor against development of benign precursor lesions of colorectal cancer. Further research is warranted to delineate the mechanisms underlying these processes.
