## Abstract

Liver fibrosis and cirrhosis are common outcomes of chronic liver diseases such as viral hepatitis, alcoholic liver disease, and non-alcoholic fatty liver disease. Despite diverse causes, they share core pathological features including hepatic stellate cell activation, extracellular matrix deposition, immune dysregulation, and metabolic alterations. Recent advances in multi-omics technologies—encompassing transcriptomics, proteomics, and metabolomics—enhance our understanding of the molecular and cellular mechanisms driving liver fibrosis. This review integrates findings from human studies and animal models, highlighting key pathological pathways and their interactions. Multi-omics analyses also clarify therapeutic mechanisms targeting oxidative stress, inflammation, and metabolic dysfunction. Cross-species comparisons confirm the translational relevance of animal models and underscore the value of multi-omics approaches in biomarker discovery and precision therapy development. Overall, these insights provide a systems-level understanding of liver fibrosis, facilitating advances in diagnosis and treatment strategies.
