{"doi":"10.1242/dev.204622","title":"<i>Caenorhabditis elegans</i> LET-381 and DMD-4 control development of the mesodermal HMC endothelial cell","abstract":"Endothelial cells form the inner layer of blood vessels and play key roles in circulatory system development and function. A variety of endothelial cell types have been described through gene expression and transcriptome studies; nonetheless, the transcriptional programs that specify endothelial cell fate and maintenance are not well understood. To uncover such regulatory programs, we studied the C. elegans head mesodermal cell (HMC), a non-contractile mesodermal cell bearing molecular and functional similarities to vertebrate endothelial cells. Here, we demonstrate that a Forkhead transcription factor, LET-381, is required for HMC fate specification and maintenance of HMC gene expression. DMD-4, a DMRT transcription factor, acts downstream of and in conjunction with LET-381 to mediate these functions. Independently of LET-381, DMD-4 also represses the expression of genes associated with a different, non-HMC, mesodermal fate. Our studies uncover essential roles for FoxF transcriptional regulators in endothelial cell development and suggest that FoxF co-functioning target transcription factors promote specific non-contractile mesodermal fates.","journal":"Development","year":2025,"id":553685,"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":1,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.954,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2025-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":1451067,"name":"Jasmine Xi","orcid":null,"position":1,"is_corresponding":false},{"id":1173391,"name":"Jessica Jiang","orcid":"0009-0000-7705-6211","position":2,"is_corresponding":false},{"id":233475,"name":"Shai Shaham","orcid":"0000-0002-3751-975X","position":3,"is_corresponding":false},{"id":1173390,"name":"Nikolaos Stefanakis","orcid":"0000-0003-0921-987X","position":0,"is_corresponding":true}],"reference_count":62,"raw_metadata":null,"created_at":"2026-07-19T02:54:45.872391Z","pmid":"40728647","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":[]}
