It was speculated that simultaneous inhibition of multiple signalling pathways might be a promising strategy to target this tumor entity. In the present study we tested the effect of histone deacetylase (HDAC) inhibition using depsipeptide (also known as romidepsin, FK228, FR901228 or NSC-630176) in cHL cell lines in vitro. Molecular mechanisms of toxicity were analyzed using RNA expression analysis and functional assays. It is shown that depsipeptide is effective at submicromolar concentrations and acts mainly by apoptosis induction, upregulation of p21 and cell cycle inhibition in G2/M. Of special note, HDAC mediated toxicity in H-RS cells does not require RelA/p65 downregulation, which was previously shown to drive the malignant phenotype of H-RS cells. In summary, depsipeptide induced protein acetylation results in transcriptional changes of a large number of pathogenetically relevant genes and increased RelA/p65 binding activity in cHL cell lines. Our preclinical data suggest that HDAC inhibition using depsipeptide might be a promising approach for the treatment of cHL patients.","is_dataset_classified":null,"base_score":3.258096538021482,"endowment":3.258096538021482,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"19233470","pmcid":null,"openalex_id":"https://openalex.org/W2045167259","authors":[],"funders":[],"total_grants":0,"fwci":2.1602,"citation_percentile":0.87093778,"influential_citations":0,"citation_trend":[{"year":2012,"count":4},{"year":2013,"count":4},{"year":2014,"count":1},{"year":2015,"count":1},{"year":2017,"count":2}],"oa_status":"closed","license":"https://www.elsevier.com/tdm/userlicense/1.0/","oa_locations":[{"url":"https://api.elsevier.com/content/article/PII:S0145212608005638?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S0145212608005638?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.leukres.2008.12.013","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/19233470","host_type":"repository"}],"fields_of_study":["Histone Deacetylase Inhibitors Research","Peptidase Inhibition and Analysis","Ubiquitin and proteasome pathways"],"mesh_terms":["Acetylation","Antibiotics, Antineoplastic","Cell Cycle","Enzyme Inhibitors","Hodgkin Disease","Humans","RNA, Messenger","Tumor Cells, Cultured","Blotting, Western","Gene Expression Regulation, Leukemic","NF-kappa B","Apoptosis","Cell Cycle Proteins","Oligonucleotide Array Sequence Analysis","Gene Expression Profiling","Depsipeptides","Cell Proliferation","Cyclin-Dependent Kinase Inhibitor p21","Histone Deacetylase Inhibitors"],"keywords":["Depsipeptide","Romidepsin","Histone deacetylase","Downregulation and upregulation","Cancer research","Histone deacetylase inhibitor","Lymphoma","Biology","Acetylation","Apoptosis","Cell culture","Vorinostat","Cell cycle","Molecular biology","Histone","Gene","Immunology","Biochemistry","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":"2026-08-04T01:38:32.309878Z","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":[]}
