The Rho GTPase, which mediates cell shape change and migration, is also an essential regulator of tissue morphogenesis during development. Rho activity can modulate gene expression, in part, by activating LIM kinase (LIMK) and consequently affecting actin-induced SRF transcriptional activity. We have established a link between Rho-LIMK-SRF signaling and the ecdysone-induced transcriptional response during Drosophila development. Specifically, we determined that the Rho GTPase, via LIMK, regulates the expression of several ecdysone-responsive genes, including those encoding the ecdysone receptor itself, a downstream transcription factor (Br-C), and Stubble, a transmembrane protease required for proper leg formation. Stubble and Br-C mutants exhibit strong genetic interactions with several Rho pathway components in the formation of adult structures, but not with Rac or Cdc42. In cultured SL2 cells, inhibition of Rho, F-actin assembly, or SRF blocks the transcriptional response to ecdysone. Together, these findings indicate a link between Rho-LIMK signaling and steroid hormone-induced gene expression in the context of metamorphosis and thereby establish a novel role for the Rho GTPase in development.","is_dataset_classified":null,"base_score":3.332204510175204,"endowment":3.332204510175204,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"14972681","pmcid":null,"openalex_id":"https://openalex.org/W1965724696","authors":[],"funders":[{"funder_name":"NIGMS NIH HHS","grant_id":"R01 GM60466","title":null}],"total_grants":1,"fwci":1.1146,"citation_percentile":0.71652997,"influential_citations":0,"citation_trend":[{"year":2013,"count":1},{"year":2014,"count":1},{"year":2015,"count":1},{"year":2016,"count":1},{"year":2020,"count":1},{"year":2022,"count":1},{"year":2023,"count":2},{"year":2024,"count":1},{"year":2025,"count":1}],"oa_status":"bronze","license":"https://www.elsevier.com/open-access/userlicense/1.0/","oa_locations":[{"url":"http://www.cell.com/article/S096098220400065X/pdf","host_type":"journal"},{"url":"http://www.cell.com/article/S096098220400065X/pdf","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S096098220400065X?httpAccept=text/xml","host_type":"publisher"},{"url":"https://api.elsevier.com/content/article/PII:S096098220400065X?httpAccept=text/plain","host_type":"publisher"},{"url":"https://doi.org/10.1016/j.cub.2004.01.056","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/14972681","host_type":"repository"}],"fields_of_study":["Neurobiology and Insect Physiology Research","Invertebrate Immune Response Mechanisms","Developmental Biology and Gene Regulation"],"mesh_terms":["Animals","Cells, Cultured","Drosophila","Ecdysone","Extremities","Membrane Proteins","Metamorphosis, Biological","Microscopy, Fluorescence","Morphogenesis","Protein Kinases","Serine Endopeptidases","Transcription Factors","Wings, Animal","Blotting, Northern","Signal Transduction","Gene Expression Regulation, Developmental","rho GTP-Binding Proteins","Drosophila Proteins","Lim Kinases"],"keywords":["Biology","Ecdysone","Ecdysone receptor","Cell biology","Transcription factor","Morphogenesis","CDC42","GTPase","Gene","Genetics","Nuclear receptor"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-16T12:10:38.774411Z","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":[]}
