Elimination or suppression of causative factors can raise the possibility of liver fibrosis regression. However, different injurious stimuli will give fibrosis from somewhat different etiologies, which, in turn, may hamper the discovery of liver fibrosis-specific therapeutic drugs. Therefore, the analogical cellular and molecular events shared by various etiology-evoked liver fibrosis should be clarified. Our present study systematically integrated five publicly available transcriptomic data sets regarding liver fibrosis with different etiologies from the Gene Expression Omnibus database and performed a series of bioinformatics analyses and experimental verifications. A total of 111 significantly upregulated and 16 downregulated genes were identified specific to liver fibrosis independent of any etiology. These genes were predominately enriched in some Kyoto Encyclopedia of Genes and Genomes pathways, including the “PI3K-AKT signaling pathway,” “Focal adhesion,” and “ECM-receptor interaction.” Subsequently, five prioritized liver fibrosis-specific genes, including COL4A2, THBS2, ITGAV, LAMB1, and PDGFRA, were screened. These genes were positively associated with each other and liver fibrosis progression. In addition, they could robustly separate all stages of samples in both training and validation data sets with diverse etiologies when they were regarded as observed variables applied to principal component analysis plots. Expressions of all five genes were confirmed in activated primary mouse hepatic stellate cells (HSCs) and transforming growth factor β1-treated LX-2 cells. Moreover, THBS2 protein was enhanced in liver fibrosis rodent models, which could promote HSC activation and proliferation and facilitate NOTCH1/JAG1 expression in HSCs. Overall, our current study may provide potential targets for liver fibrosis therapy and aid to a deeper understanding of the molecular underpinnings of liver fibrosis.    NEW &amp; NOTEWORTHY Prioritized liver fibrosis-specific genes THBS2, COL4A2, ITGAV, LAMB1, and PDGFRA were identified and significantly associated with liver fibrosis progression and could be combined to discriminate liver fibrosis stages regardless of any etiology. Among the identified prioritized liver fibrosis-specific targets, THBS2 protein was confirmed to be enhanced in liver fibrosis rodent models, which could promote hepatic stellate cell (HSC) activation and proliferation and facilitate NOTCH1/JAG1 expression in HSCs.
