In the written paragraphs, I have clearly identified the source of the passages that are quoted or paraphrased from other works. I also hereby declare that I have conducted my scientific work according to the principles of good scientific practice in accordance with the current “Richtlinien der Freien Universität Berlin” (Guidelines of the Free University of Berlin) and “Charte du doctorat à l’UPMC” (Charter of PhD students at UPMC). I, Mina Petkova, received assistance in the writing of this thesis with respect to grammar and syntax, which was provided by Markus Schuelke and Helge Amthor. Berlin, 6.01.2016 _______________ (Signature) ACKNOWLEDGMENTS I would like to cordially thank all whose support and encouragement contributed to the successful completion of my doctoral thesis. First of all, I would like to thank my supervisors Prof. Dr. M. Schuelke and Prof. Dr. H. Amthor for giving me the opportunity to work on an exciting project over the past 4.5 years. I will always appreciate their scientific advice and their work ethics. I am very grateful to Prof. Dr. M. Schuelke for his generosity, his unconditional support, his guidance and for giving me the freedom to conduct research. His interest and passion in the field of the biomedical research, and his optimism always encouraged me and contributed to the success of my work. I would like to cordially thank Prof. Dr. S. Stricker of the Freie Universitat Berlin for his agreement to review my doctoral thesis. I would like to cordially thank Prof. Dr. V. Straub and Prof. Dr. K. Patel for their willingness to review my doctoral thesis. I thank Dr. G. Butler-Browne for agreeing to be part of my thesis committee. I would like to express special thanks to all current and former co-workers of the Schuelke group in Berlin for their help, understanding, for their encouragment, and for the friendly and nice work atmosphere. I would especially like to thank Susanne, Esther and Franziska for their technical assistance. I am very thankful to Can for her unconditional support, great discussions, understanding and friendship. I am grateful to Evelyn and Sophie, students who helped and supported my project. I would also like to thank the members of the group of Prof. Dr. H. Amthor and Dr. L. Garcia at the Université Saint-Quentin en Yvelines, especially to Amalia and Sonia. I also would like to thank Josefine Radke and co-workers at the Institute of Neuropathology at the Charité Universitätsmedizin, Berlin for performing the histological analysis and western blots. I would like to thank Polygene AG, Switzerland for the generation of the transgenic mice. I am thankful to the group of Prof. Dr. Carmen Birchmeier from MDC-Berlin for providing the Cre-deleter mice. I want to thank to all co-workers of the animal facilities of the Charité Cross Over building, as well as in the central animal facility FEM in Berlin for caring and breeding of experimental animals. I would like to thank MyoGrad for giving me the opportunity to be part of a bi-national PhD program. Thanks to all students and to the organization team, especially Susanne Wissler. I would like to thank my family, especially my parents and my grandmother for their love, for their support each step of the way, for giving me the chance to explore different opportunities, and ultimately to achieve this important goal.
