Small Rho GTPase RhoA is a key regulator of cytoskeletal organization which regulates cell polarity, migration, and division. In this study, we investigated the roles of RhoA in mammalian oocyte meiosis and early embryo cleavage. (1) Disrupting RhoA activity or knock down the expression of RhoA caused the failure of polar body emission. This may have been due to decreased actin assembly and subsequent spindle migration defects. The involvement of RhoA in this process may have been though its regulation of actin nucleators ROCK, p-Cofilin, and ARP2 expression. (2) In addition, spindle morphology was also disrupted and p-MAPK expression decreased in RhoA inhibited or RhoA KD oocytes, which indicated that RhoA also regulated MAPK phosphorylation for spindle formation. (3) Porcine embryo development was also suppressed by inhibiting RhoA activity. Two nuclei were observed in one blastomere, and actin expression was reduced, which indicated that RhoA regulated actin-based cytokinesis of porcine embryo. Thus, our results demonstrated indispensable roles for RhoA in regulating porcine oocyte meiosis and cleavage during early embryo development.","is_dataset_classified":null,"base_score":4.290459441148391,"endowment":4.290459441148391,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"25485583","pmcid":"PMC4613651","openalex_id":"https://openalex.org/W2001242427","authors":[],"funders":[],"total_grants":0,"fwci":8.2355,"citation_percentile":0.97880945,"influential_citations":0,"citation_trend":[{"year":2015,"count":3},{"year":2016,"count":10},{"year":2017,"count":13},{"year":2018,"count":12},{"year":2019,"count":7},{"year":2020,"count":5},{"year":2021,"count":3},{"year":2022,"count":8},{"year":2023,"count":2},{"year":2024,"count":2},{"year":2025,"count":4},{"year":2026,"count":3}],"oa_status":"bronze","license":null,"oa_locations":[{"url":"https://www.tandfonline.com/doi/pdf/10.4161/15384101.2014.952967?needAccess=true","host_type":"journal"},{"url":"https://www.tandfonline.com/doi/pdf/10.4161/15384101.2014.952967?needAccess=true","host_type":"publisher"},{"url":"http://www.tandfonline.com/doi/pdf/10.4161/15384101.2014.952967","host_type":"publisher"},{"url":"https://doi.org/10.4161/15384101.2014.952967","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/25485583","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/4613651","host_type":"repository"}],"fields_of_study":["Reproductive Biology and Fertility","Pluripotent Stem Cells Research","Microtubule and mitosis dynamics","Actin Depolymerizing Factors","Actin-Related Protein 2","Actins","Animals","Cells, Cultured","Cytoskeleton","Embryo, Mammalian","Embryonic Development","Microscopy, Confocal","Mitogen-Activated Protein Kinases","Oocytes","Oogenesis","Phosphorylation","Polar Bodies","RNA Interference","RNA, Small Interfering","Spindle Apparatus","Swine","rho-Associated Kinases","rhoA GTP-Binding Protein"],"mesh_terms":["Actins","Animals","Cells, Cultured","Cytoskeleton","Embryo, Mammalian","Spindle Apparatus","Oocytes","Oogenesis","Phosphorylation","Swine","Microscopy, Confocal","rhoA GTP-Binding Protein","Mitogen-Activated Protein Kinases","RNA Interference","RNA, Small Interfering","Embryonic Development","Actin Depolymerizing Factors","Actin-Related Protein 2","rho-Associated Kinases","Polar Bodies"],"keywords":["RHOA","Cell biology","Biology","Cytokinesis","Small GTPase","Cytoskeleton","Actin cytoskeleton","Oocyte activation","Oocyte","Cell division","Embryo","Signal transduction","Genetics","Cell","Actin","Arp2/3 Complex","Gvbd, Germinal Vesicle Breakdown","Mt, Microtubule","Cgfd, Cortical Granule-free Domain","Cocs, Cumulus Oocyte Complexs","Dos, Denuded Oocytes","Kd, Knock Down","Mii, Metaphase Ii","Npfs, Nucleation Promoting Factors","Rhoaspindle Formation"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-28T13:10:30.426339Z","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":[]}
