In recent years, however, their reproducibility is criticized. The performance of feature selection algorithms is shown to be affected by the datasets, underlying networks and evaluation metrics. One of the causes is the curse of dimensionality, which makes it hard to select the features that generalize well on independent data. Even the integration of biological networks does not mitigate this issue because the networks are large and many of their components are not relevant for the phenotype of interest. With the availability of multi-omics data, integrative approaches are being developed to build more robust predictive models. In this scenario, the higher data dimensions create greater challenges. We proposed a phenotype relevant network-based feature selection (PRNFS) framework and demonstrated its advantages in lung cancer prognosis prediction. We constructed cancer prognosis relevant networks based on epithelial mesenchymal transition (EMT) and integrated them with different types of omics data for feature selection. With less than 2.5% of the total dimensionality, we obtained EMT prognostic signatures that achieved remarkable prediction performance (average AUC values >0.8), very significant sample stratifications, and meaningful biological interpretations. In addition to finding EMT signatures from different omics data levels, we combined these single-omics signatures into multi-omics signatures, which improved sample stratifications significantly. Both single- and multi-omics EMT signatures were tested on independent multi-omics lung cancer datasets and significant sample stratifications were obtained.","is_dataset_classified":null,"base_score":2.0794415416798357,"endowment":2.0794415416798357,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"30703089","pmcid":"PMC6354965","openalex_id":"https://openalex.org/W2889758478","authors":[],"funders":[{"funder_name":"Bundesministerium für Bildung und Forschung","grant_id":"3FO18501 (Forschungscampus MODAL)","title":null}],"total_grants":1,"fwci":0.455,"citation_percentile":0.58958632,"influential_citations":0,"citation_trend":[{"year":2020,"count":3},{"year":2021,"count":2},{"year":2022,"count":1},{"year":2024,"count":1}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0204186&type=printable","host_type":"journal"},{"url":"https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0204186&type=printable","host_type":"publisher"},{"url":"http://dx.plos.org/10.1371/journal.pone.0204186","host_type":"publisher"},{"url":"https://doi.org/10.1371/journal.pone.0204186","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/30703089","host_type":"repository"},{"url":"http://europepmc.org/pmc/articles/PMC6354965","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/6354965","host_type":"repository"},{"url":"https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0204186","host_type":"repository"},{"url":"https://doaj.org/article/d1bfedd092ab4fa6948842f6c3735daa","host_type":"repository"},{"url":"https://figshare.com/articles/dataset/EMT_network-based_feature_selection_improves_prognosis_prediction_in_lung_adenocarcinoma/7656395","host_type":"repository"},{"url":"http://hdl.handle.net/10852/74621","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC6354965","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC6354965?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Bioinformatics and Genomic Networks","Gene expression and cancer classification","Ferroptosis and cancer prognosis","Adenocarcinoma of Lung","Algorithms","Biomarkers, Tumor","Datasets as Topic","Epithelial-Mesenchymal Transition","Gene Expression Profiling","Gene Expression Regulation, Neoplastic","Gene Regulatory Networks","Genomics","Humans","Lung Neoplasms","Models, Biological","Prognosis","Reproducibility of Results"],"mesh_terms":["Adenocarcinoma of Lung","Algorithms","Humans","Lung Neoplasms","Models, Biological","Prognosis","Biomarkers, Tumor","Reproducibility of Results","Gene Expression Regulation, Neoplastic","Gene Expression Profiling","Genomics","Gene Regulatory Networks","Epithelial-Mesenchymal Transition","Datasets as Topic"],"keywords":["Feature selection","Omics","Curse of dimensionality","Computer science","Dimensionality reduction","Data mining","Feature (linguistics)","Machine learning","Bioinformatics","Computational biology","Artificial intelligence","Biology"],"sdg_mappings":[{"sdg_number":0,"sdg_label":"Good health and well-being"}],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"doi"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-17T12:50:45.418289Z","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":[]}
