As a primary objective, this dissertation aimed at contributing to the field of translational hepatology with a particular focus on liver diseases of toxic and chronic nature. In order to achieve this, a wide spectrum of biomedical research methodologies were applied, including the development of experimental models of toxic and chronic liver disease both in vitro and in vivo, the application of molecular laboratory techniques, the analysis of human liver samples from human biobanks, the design of clinical-epidemiological studies as well as the analysis of the earlier published scientific literature. The present work is introduced by a general introduction that is subsequently followed by three additional sections (listed as sections I, II and III) that correspond to the performed scientific work and main conclusions. The research shown in the first part of this manuscript were intended to widen our knowledge on drug-induced liver injury, abbreviated as “DILI” (Section I; Chapters 2-8). Here, the following thematic aspects were investigated: Evaluation of the role of the c-Jun N-terminal kinase (abbreviated as "JNK") at the hepatocytic level
