Here we show that the most common mouse strain, C57Bl6/J, is resistant to maternal aging, showing little increase in aneuploidy or Sgo2 loss. Instead it demonstrates significant kinetochore-associated loss in the spindle assembly checkpoint protein Mad2 and phosphorylated Aurora C, which is involved in microtubule-kinetochore error correction. Their loss affects the fidelity of bivalent segregation but only when spindle organization is impaired during oocyte maturation. These findings have an impact clinically regarding the handling of human oocytes ex vivo during assisted reproductive techniques and suggest there is a genetic basis to aneuploidy susceptibility.","is_dataset_classified":null,"base_score":4.1588830833596715,"endowment":4.1588830833596715,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"24758999","pmcid":"PMC4111757","openalex_id":"https://openalex.org/W1994567108","authors":[],"funders":[],"total_grants":0,"fwci":3.5125,"citation_percentile":0.92827719,"influential_citations":0,"citation_trend":[{"year":2014,"count":2},{"year":2015,"count":7},{"year":2016,"count":4},{"year":2017,"count":12},{"year":2018,"count":9},{"year":2020,"count":4},{"year":2021,"count":5},{"year":2022,"count":6},{"year":2023,"count":2},{"year":2024,"count":7},{"year":2025,"count":2},{"year":2026,"count":3}],"oa_status":"bronze","license":null,"oa_locations":[{"url":"https://www.tandfonline.com/doi/pdf/10.4161/cc.28897?needAccess=true&role=button","host_type":"journal"},{"url":"https://www.tandfonline.com/doi/pdf/10.4161/cc.28897?needAccess=true&role=button","host_type":"publisher"},{"url":"http://www.tandfonline.com/doi/pdf/10.4161/cc.28897","host_type":"publisher"},{"url":"https://doi.org/10.4161/cc.28897","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/24758999","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/4111757","host_type":"repository"},{"url":"http://hdl.handle.net/2440/115684","host_type":"repository"},{"url":"https://eprints.soton.ac.uk/364423/","host_type":"repository"},{"url":"http://hdl.handle.net/1959.13/1303637","host_type":"repository"}],"fields_of_study":["Microtubule and mitosis dynamics","Nuclear Structure and Function","Reproductive Biology and Fertility","Aging","Aneuploidy","Animals","Aurora Kinase C","Cell Cycle Proteins","Chromosome Segregation","Female","Kinetochores","M Phase Cell Cycle Checkpoints","Mad2 Proteins","Mice","Mice, Inbred C57BL","Nocodazole","Oocytes","Species Specificity","Spindle Apparatus"],"mesh_terms":["Aging","Aneuploidy","Animals","Female","Mice, Inbred C57BL","Spindle Apparatus","Oocytes","Species Specificity","Nocodazole","Kinetochores","Cell Cycle Proteins","Chromosome Segregation","Mice","M Phase Cell Cycle Checkpoints","Aurora Kinase C","Mad2 Proteins"],"keywords":["Kinetochore","Spindle checkpoint","Biology","Cell biology","Spindle apparatus","Microtubule","Spindle pole body","Genetics","Cell division","Cell","Chromosome","Aging","Meiosis","Cell cycle","Oocyte","Aneuploidy","Error correction","Spindle Assembly Checkpoint"],"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":"2026-08-16T12:13:44.030022Z","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":[]}
