In this study, we show that the MEK5/ERK5 pathway participates in osteoclast differentiation. ERK5 was activated by M-CSF, which is one of the essential factors in osteoclast differentiation. Inhibition of MEK5 by BIX02189 or inhibition of ERK5 by XMD 8-92 blocked osteoclast differentiation. MEK5 knockdown inhibited osteoclast differentiation. RAW264.7D clone cells, which are monocytic cells, differentiate into osteoclasts after stimulation with sRANKL. ERK5 was activated without any stimulation in these cells. Inhibition of the MEK5/ERK5 pathway by the inhibitors also blocked the differentiation of RAW264.7D cells into osteoclasts. Moreover, expression of the transcription factor c-Fos, which is indispensable for osteoclast differentiation, was inhibited by treatment with MEK5 or ERK5 inhibitors. Therefore, activation of ERK5 is required for the induction of c-Fos. These events were confirmed in experiments using M-CSF-dependent bone marrow macrophages. Taken together, the present results show that activation of the MEK5/ERK5 pathway with M-CSF is required for osteoclast differentiation, which may induce differentiation through the induction of c-Fos.","is_dataset_classified":null,"base_score":3.367295829986474,"endowment":3.367295829986474,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"25885811","pmcid":"PMC4401765","openalex_id":"https://openalex.org/W1980354722","authors":[],"funders":[],"total_grants":0,"fwci":1.926,"citation_percentile":0.85785034,"influential_citations":0,"citation_trend":[{"year":2016,"count":2},{"year":2017,"count":7},{"year":2018,"count":5},{"year":2019,"count":1},{"year":2020,"count":5},{"year":2021,"count":2},{"year":2022,"count":3},{"year":2023,"count":1},{"year":2024,"count":2}],"oa_status":"gold","license":"cc-by","oa_locations":[{"url":"https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0125054&type=printable","host_type":"journal"},{"url":"https://journals.plos.org/plosone/article/file?id=10.1371/journal.pone.0125054&type=printable","host_type":"publisher"},{"url":"http://dx.plos.org/10.1371/journal.pone.0125054","host_type":"publisher"},{"url":"https://doi.org/10.1371/journal.pone.0125054","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/25885811","host_type":"repository"},{"url":"https://www.ncbi.nlm.nih.gov/pmc/articles/4401765","host_type":"repository"},{"url":"https://doaj.org/article/98359c35b1154f599b342febcac38317","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC4401765","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC4401765?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["Bone Metabolism and Diseases","Bone health and treatments","Melanoma and MAPK Pathways","Acid Phosphatase","Aniline Compounds","Animals","Benzodiazepinones","Bone Marrow Cells","Cell Differentiation","Cell Line","Enzyme Activation","Humans","Indoles","Isoenzymes","MAP Kinase Kinase 5","Macrophage Colony-Stimulating Factor","Male","Mice, Inbred Strains","Mitogen-Activated Protein Kinase 7","Osteoclasts","Phosphorylation","Protein Kinase Inhibitors","Proto-Oncogene Proteins c-fos","RANK Ligand","Tartrate-Resistant Acid Phosphatase"],"mesh_terms":["Tartrate-Resistant Acid Phosphatase","Acid Phosphatase","Aniline Compounds","Animals","Benzodiazepinones","Bone Marrow Cells","Cell Differentiation","Cell Line","Enzyme Activation","Humans","Indoles","Isoenzymes","Male","Mice, Inbred Strains","Osteoclasts","Phosphorylation","Macrophage Colony-Stimulating Factor","Proto-Oncogene Proteins c-fos","Protein Kinase Inhibitors","Mitogen-Activated Protein Kinase 7","MAP Kinase Kinase 5","RANK Ligand"],"keywords":["Osteoclast","Cell biology","Cellular differentiation","MAPK/ERK pathway","Gene knockdown","Chemistry","Transcription factor","Signal transduction","Biology","In vitro","Biochemistry","Apoptosis","Gene"],"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":"2026-08-17T13:36:15.396250Z","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":[]}
