Even though our knowledge of the cellular and molecular mechanisms of liver fibrosis has deeply improved in the last years, therapeutic approaches for liver fibrosis remain limited. Profiling and characterization of the post-translational modifications (PTMs) of proteins, and more specifically NEDDylation and SUMOylation ubiquitin-like (Ubls) modifications, can provide a better understanding of the liver fibrosis pathology as well as novel and more effective therapeutic approaches. -

The genetic contribution to human T2D and related metabolic disorders is evident, and mostly follows polygenic inheritance. The TALLYHO/ JngJ (TH) mice are a polygenic model for T2D characterized by obesity, hyperinsulinemia, impaired glucose uptake and tolerance, hyperlipidemia, and hyperglycemia. -

In addition, cells can be pushed toward death when they accumulate genetic errors, are virally-infected or are otherwise deemed potentially-harmful to the overall organism. Caenorhabditis elegans has proved to be an excellent model system for elucidating the genetic underpinnings of cell death, and research has shown that the core machinery, made up of the egl-1, ced-9, ced-4 and ced-3 genes, is conserved across metazoans, and their homologues are crucial for such diseases as cancer, neurodegeneration and autoimmunity. -

I am very grateful to you for advice, guidance, valuable comments, for your suggestions and for your didactic way in clarifying the ideas, because of you, I have learned how to always think with a scientific essence. A special appreciation is extended to the Japanese Ministry of Education, Culture, Sports, Science, and Technology for providing me the financial assistance which kept away the irritating sensation of financial instability. In our days when role models have become fewer and fewer, I had the privilege of being shaped by an intelligent researcher, Dr. Moustafa Sarhan. I gratefully acknowledge Dr. Moustafa, my mentor, and my best friend, whose passion for helping sets new standards for anyone involved in training and development, or any other endeavor in which one human being seeks to support the growth and improvement of another. I would also like to thank all previous and current members of our laboratory especially Haruka Takase, Shiho Koyama, Koichi Miyagawa, Mayo Nakanishi for their help and for providing useful comments during my research. Special thanks to Dr. Haruka Nishida who helped me to set up my stay and take care of every single detail to make my life more enjoyable in Japan. -
F-Box Protein FBXO31 Directs Degradation of MDM2 to Facilitate P53-Mediated Growth Arrest Following Genotoxic Stress

In response to genotoxic stress, p53 levels increase and in- levels, as there is for p53 (9). These considerations prompted us to duce cell-cycle arrest, senescence, or apoptosis, thereby preventing ask whether there was a functional relationship between FBXO31 replication of damaged DNA. In unstressed cells, p53 is maintained and p53. at a low level. The major negative regulator of p53 is MDM2, an E3 ubiquitin ligase that directly interacts with p53 and promotes its Results polyubiquitination, leading to the subsequent destruction of p53 by FBXO31 Is Required for Decreased MDM2 and Increased p53 Levels the 26S proteasome. Following DNA damage, MDM2 is degraded Following DNA Damage. We asked whether the ability of FBXO31 rapidly, resulting in increased p53 stability. Because of the important to induce growth arrest results, at least in part, from the regulation role of MDM2 in modulating p53 function, it is critical to understand of p53 levels. -
