Aberrant activation of the Met signaling pathway is frequently associated with tumor progression and metastasis. In this study, we defined the Met-dependent gene expression signature using global gene expression profiling of WT and Met-deficient primary mouse hepatocytes. Newly identified transcriptional targets of the Met pathway included genes involved in the regulation of oxidative stress responses as well as cell motility, cytoskeletal organization, and angiogenesis. To assess the importance of a Met-regulated gene expression signature, a comparative functional genomic approach was applied to 242 human hepatocellular carcinomas (HCCs) and 7 metastatic liver lesions. Cluster analysis revealed that a subset of human HCCs and all liver metastases shared the Met-induced expression signature. Furthermore, the presence of the Met signature showed significant correlation with increased vascular invasion rate and microvessel density as well as with decreased mean survival time of HCC patients. We conclude that the genetically defined gene expression signatures in combination with comparative functional genomics constitute an attractive paradigm for defining both the function of oncogenic pathways and the clinically relevant subgroups of human cancers.","is_dataset_classified":null,"base_score":5.971261839790462,"endowment":5.971261839790462,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"16710476","pmcid":"PMC1462944","openalex_id":"https://openalex.org/W2042571415","authors":[],"funders":[{"funder_name":"Intramural NIH HHS","grant_id":"","title":null},{"funder_name":"Intramural NIH HHS","grant_id":"","title":null}],"total_grants":2,"fwci":8.4185,"citation_percentile":0.98110493,"influential_citations":0,"citation_trend":[{"year":2012,"count":45},{"year":2013,"count":31},{"year":2014,"count":20},{"year":2015,"count":31},{"year":2016,"count":32},{"year":2017,"count":20},{"year":2018,"count":17},{"year":2019,"count":16},{"year":2020,"count":17},{"year":2021,"count":15},{"year":2022,"count":12},{"year":2023,"count":17},{"year":2024,"count":2},{"year":2025,"count":7},{"year":2026,"count":2}],"oa_status":"bronze","license":null,"oa_locations":[{"url":"http://www.jci.org/articles/view/27236/files/pdf","host_type":"journal"},{"url":"http://www.jci.org/articles/view/27236/files/pdf","host_type":"publisher"},{"url":"https://doi.org/10.1172/jci27236","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/16710476","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/1462944","host_type":"repository"}],"fields_of_study":["Liver physiology and pathology","MicroRNA in disease regulation","Endoplasmic Reticulum Stress and Disease","Animals","Carcinoma, Hepatocellular","Cells, Cultured","Female","Gene Expression Profiling","Gene Expression Regulation, Neoplastic","Hepatocyte Growth Factor","Hepatocytes","Humans","Liver Neoplasms","Male","Mice","Mice, Knockout","Middle Aged","Molecular Sequence Data","Neoplasm Metastasis","Oligonucleotide Array Sequence Analysis","Phenotype","Prognosis","Proto-Oncogene Proteins","Proto-Oncogene Proteins c-met","Receptors, Growth Factor","Survival Rate"],"mesh_terms":["Animals","Cells, Cultured","Female","Carcinoma, Hepatocellular","Humans","Liver Neoplasms","Male","Middle Aged","Molecular Sequence Data","Neoplasm Metastasis","Phenotype","Prognosis","Proto-Oncogene Proteins","Gene Expression Regulation, Neoplastic","Survival Rate","Hepatocyte Growth Factor","Receptors, Growth Factor","Mice, Knockout","Proto-Oncogene Proteins c-met","Oligonucleotide Array Sequence Analysis","Gene Expression Profiling","Hepatocytes","Mice"],"keywords":["HCCS","Gene signature","Biology","Gene expression profiling","Gene expression","Phenotype","Cancer research","Gene","Metastasis","Regulation of gene expression","Angiogenesis","Transcriptome","Hepatocellular carcinoma","Cancer","Genetics"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-23T16:39:50.993990Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
