Tao and Xiaoqi Liu as well as committee co-chairs Ourania Andrisani and Fabien Zoulim for accepting to read, evaluate and thoughtfully critique my work. I also thank them for their confidence, continuous support and mentorship throughout my stay at Purdue. I would like to express my sincerest gratitude to my mentor and adviser Ourania Andrisani for her exceptional mentorship and the tremendous support she provided throughout the years. Her dedication to her work was inspiration, attention to detail and perseverance was inspirational. I appreciate her relentless encouragement, being readily available for scientific, intellectual and emotional support as well as her honest and constructive advice. I would like also to thank Fabien Zoulim and David Durantel for cordially granting me the opportunity to work with them and for their continuous professional and scientific support. My stay at INSERM Lyon was extremely beneficial for my scientific and personal development and it would have not been possible without their support. I will be utterly grateful for the expertise and experience I gained under their mentorship. iii I owe very special thanks to Ronald Hullinger for his outstanding mentorship, continuous support and the intellectual encounters. His wittiness, hospitability and exceptional culinary skills made my stay at Purdue memorable. I would like also thank my colleagues at the Andrisani lab, Saravana Kumar Mani, Hao Zhang, Huitao Fan, Zhibin Cui, Dante Johnson, Ellen Weigel, Zuo Ding and Li Ma. I would like to thank Adrien Foca, Nathalie Isorce, Dulce Alfaiate, Pascal Jalaguier, Suzanne Faure-Dupuy, Maëlle Locatelli, Valentina D’Arienzo and Olivier Hantz at INSERM Lyon. I would like to particularly thanks Adrien Foca for his tremendous help to complete my work on the PLK1 project in Lyon. It has been a pleasure to work with him. I am also obligated to thank my colleagues at Purdue Wen-Hung Want, I-Hsuan (Blair) Chen, Meng-Ju Wu, Anton Iliuk, Mariya Krisenko, Lama Alabdi and Cindy Xing for their help. I particularly thank I-Hsuan chen for her help with the mass spectrometry work. I thank François-Loïc Cosset and Floriane Fusil for the work on the humanized-liver mice and their help extending my findings to in vivo models. Finally, I would like to thank my friends at Purdue who made Lafayette a second home and my family for their belief in me and their continuous encouragement. iv TABLE OF CONTENTS Page LIST OF TABLES .................................................................................................................... ix LIST OF FIGURES ................................................................................................................... x LIST OF ABBREVIATIONS .................................................................................................... xii CHAPTER 1.
