ACKNOWLEDGEMENT
I would like to extend my deepest gratitude to the examiners of my PhD for the evaluation of my work and their
precious time, which they gave up for me, especially the examiners who came from England or Germany to
Paris.
Special thanks to Prof. Auclair for presiding over my PhD exam.
Thanks go to Prof. Flower and Prof. Scheller for presenting their expert's opinion of my work.
I would like to express my gratitude to Dr Cassio, Prof. Gerke and Prof. Greven for having accepted to examine
my PhD work and presentation.
Furthermore, I would very much like to thank my supervisors - Dr Françoise Russo-Marie and Prof. Frank
Wunderlich - for the opportunity presented to me to work on an international French-German PhD, for the
interesting project and for their great support over more than three years.
I would like to extend my thanks to Prof. Volker Gerke for the opportunity to finish the PhD program in his
Institute in Münster, for the confidence he placed in me and for his professional advice and helpful discussions.
I would also like to thank Dr Ursula Rescher for the warm welcome given to me on joining her group in
Münster, for countless ideas, discussions and advice and for her great support that was indispensable for my
work.
I would like to thank the Ecole Doctorale de Cancerologie and the Fakultät der Mathematisch-
Naturwissenschaftlichen Fakultät of the University of Duesseldorf, especially Prof. Tursz, Prof. Fischer, Prof.
Auclair, Prof. Westhoff, Prof. Wunderlich, Dr Lipinski, Dr Stüber, Frau Simons and Mme Nicoleti for realizing
this French-German PhD program.
I thank the professors of the IFSBM for instructive classes and especially Dr Marie-Claude La Bastie for her
interest and support.
I thank the DAAD for the funding during the first and the second year of the PhD program.
A big thank you to...
... Dr Violaine David for teaching me about protein purification and for her joy in sharing her knowledge with
me but also for her great support concerning Parisian life,
... Dr Luc Camoin for teaching me in two-dimensional gel electrophoresis among other techniques,
... Dr Morgane Bomsel, Dr Jean-Paul Mira, Dr Blandine Geny, Dr Uriel Hazan, Dr Anke Strey and Dr Hélène
Conjeaud for technical and non-technical advices,
... Maryline Bajolle for organizing the many French-German administrative affairs,
... all PhD and non-PhD students of the Cochin Institute, especially Vincent, Sylvie, Aude, Karine and Fabien
and those of the Institute for Medical Biochemistry, especially Nicole, Carsten La, Carsten Lu, Verena, Daniela,
Stephanie, Judith, Katrin, Claas, Marcin, Elin, Max, Annette and Andreas for having accepted my German or
French attitudes respectively, for the good atmosphere and for their spontaneous help in all situations and
Christian`s support with the French computer system,
… Frances Sherwood-Brock for proof-reading my thesis for linguistic errors,
... my always understanding parents, my sister and brother-in-law, Rolf, my god-mothers along with their
husbands (Ingeborg & Norbert Hartmann and Christa & Heinz Langfeld),
... Ben who was my biggest support during the first two years and remained so for the course of my last PhD
year,
... my friends Florence, Sandra, Michaela, Christoph, Bianca, René, Nicole, Katrin, Kiki, Julia and Ines for
listening, being patient, and a great support and diversion
and last but not least I thank warmly my godchildren Luzi-Leonie, Ronja and Johanna. Their smiles made me
often forget my stress and worries. Summary
