Efficient recovery from BM failure is dictated not only by the intrinsic sensitivity and proliferation capacity of the hematopoietic stem and progenitor cells but also by the BM environment niche. Identification of genetic factors that improve recovery from hematopoietic failure is essential. Vertebrate SETD4 is a poorly characterized and putatively nonhistone methyltransferase. This study aims to identify the roles of SETD4 in BM recovery. METHODS AND MATERIALS: mice were included as another control. Those mice were irradiated to induce hematopoietic syndrome and analyzed to identify the roles and mechanisms of Setd4 in of BM recovery. RESULTS: Loss of Setd4 in adult mice improved the survival of whole-body irradiation-induced BM failure. This was associated with improved recoveries of long-term and short-term hematopoietic stem cells (HSCs) and early progenitor cells. BM transplantation analyses surprisingly showed that the improved recovery was not due to radiation resistance of the Setd4-deficient HSCs but that Setd4-deficient HSCs were actually more sensitive to radiation. However, the Setd4-deficient mice were better recipients for allogeneic HSC transplantation. Furthermore, there was enhanced splenic erythropoiesis in Setd4-deficient mice. CONCLUSION: These findings not only revealed a previously unrecognized role of Setd4 as a unique modulator of hematopoiesis but also underscored the critical role of the BM niche in recovery from hematopoietic failure. Our study also implicated Setd4 as a potential target for therapeutic inhibition to improve the conditioning of the BM niche before allogeneic transplantation.","journal":"International Journal of Radiation Oncology*Biology*Physics","year":2020,"id":86827,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":12,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9576,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2020-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":442969,"name":"Huimei Lu","orcid":null,"position":1,"is_corresponding":false},{"id":265869,"name":"Jingyin Yue","orcid":"0000-0002-6698-7149","position":2,"is_corresponding":false},{"id":307626,"name":"Megha Shettigar","orcid":"0000-0003-0983-7715","position":3,"is_corresponding":false},{"id":442172,"name":"Jingmei Liu","orcid":"0000-0001-5726-6254","position":4,"is_corresponding":false},{"id":425703,"name":"Lisa Denzin","orcid":"0000-0002-0554-4547","position":5,"is_corresponding":false},{"id":284823,"name":"Zhiyuan Shen","orcid":"0000-0003-2834-0309","position":6,"is_corresponding":false},{"id":442171,"name":"Xing Feng","orcid":"0000-0001-8226-3389","position":0,"is_corresponding":true}],"reference_count":55,"raw_metadata":null,"created_at":"2026-07-18T21:59:03.706190Z","pmid":"32259569","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":[]}
