Final Report Abstract

A fundamental principle of life is the ability to maintain the functioning of biological systems in a changing environment. To achieve this, organisms have developed safeguarding mechanisms that monitor the integrity and functionality of their structures at all levels: from organs and tissues, cells, cellular organelles and subcellular compartments, to molecular machines and individual macromolecules. Cellular surveillance systems sense dysfunction or damage of individual components and elicit adaptive stress responses to ensure cellular or organismal survival by orchestrating their repair, removal and replacement. Failure or deregulation of these surveillance mechanisms is associated with aging and a plethora of diseases including cancer, neurodegeneration and inflammatory disorders. The CRC1036 was aiming at a molecular understanding of cellular stress response and surveillance pathways. In essence, this requires elucidation of how stress renders molecules, macromolecular assemblies and cellular processes damaged and dysfunctional, and how stress states and damage are sensed and signaled to elicit the appropriate response. Dozens of different quality control pathways exist within cells, making a comprehensive analysis challenging. We therefore established the CRC1036 consortium that allows to comparatively and synergistically investigate a spectrum of different strategic elements and mechanisms employed by stress responses and repair systems. In the two funding periods, we studied surveillance systems for DNA, RNA and proteins and the processes related to synthesis of these molecules (e.g. transcription and translation). This work generated new insights into fundamental principles at several levels, including new regulatory mechanisms that connect individual systems at the systemic level. We provided an in-depth analysis of selected stress sensing and signaling mechanisms as well as of damage repair and elimination mechanisms at the molecular and structural level, with major emphasis on protein quality control. Overall, the CRC is embedded in the environment of the Heidelberg/Mannheim life science campus, drawing expertise from seven participating basic biology and biomedical research centers (ZMBH, BZH, COS, DKFZ, EMBL, Medical Faculties Heidelberg and Mannheim). This broad structure of the consortium provided the basis for reaching major steps towards its long-term goal of gaining mechanistic understanding of cellular surveillance systems and damage response pathways.
