(CCL) on ovariectomy (OVX)-induced osteoporosis (OP) and elucidate the underlying molecular mechanisms, focusing on the VCP-METTL3 axis. The bioactive components of CCL were identified using liquid chromatography-mass spectrometry. An OVX-induced OP mouse model was established and treated with CCL. Bone microarchitecture was assessed by micro-CT, and bone metabolism markers were measured by ELISA. In vitro, bone marrow-derived mesenchymal stem cells (BMSCs) were used to assess osteogenic differentiation (alkaline phosphatase and alizarin red S staining). N 6 -methyladenosine (m 6 A) levels were quantified colorimetrically. Protein expression and interactions were analyzed by Western blot, co-immunoprecipitation, and immunohistochemistry. Protein stability and ubiquitination levels were assessed following cycloheximide (CHX) and MG132 treatments. Potential targets were screened via bioinformatics. CCL alleviated bone loss in OVX mice, improving bone volume/total volume (BV/TV), trabecular number (Tb.N), and trabecular thickness (Tb.Th), while reducing trabecular separation/spacing (Tb.Sp). It also restored the balance between bone formation and resorption. In BMSCs, CCL enhanced osteogenic differentiation and increased m 6 A levels by stabilizing METTL3, extending its half-life. Mechanistically, CCL targeted VCP, inhibiting its interaction with METTL3. VCP, in concert with the E3 ligase BARD1, promoted METTL3 ubiquitination and proteasomal degradation. Knockdown of METTL3 attenuated the pro-osteogenic effects of CCL. Conversely, METTL3 overexpression rescued the inhibitory effects of VCP overexpression on osteogenesis. CCL alleviates OP by targeting VCP to inhibit BARD1-mediated METTL3 ubiquitination and degradation, thereby promoting osteogenic differentiation. These findings highlight the VCP/METTL3 axis as a potential therapeutic target for OP.","is_dataset_classified":null,"base_score":0.6931471805599453,"endowment":0.6931471805599453,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"42257759","pmcid":"PMC13246569","openalex_id":"https://openalex.org/W7163871323","authors":[],"funders":[{"funder_name":"The Special Fund of Sichuan Provincial Administration of Traditional Chinese Medicing","grant_id":"2024MS179","title":null}],"total_grants":1,"fwci":3.8734,"citation_percentile":0.94605784,"influential_citations":0,"citation_trend":[{"year":2026,"count":1}],"oa_status":"hybrid","license":"cc-by-nc-nd","oa_locations":[{"url":"https://link.springer.com/content/pdf/10.1007/s10735-026-10846-8.pdf","host_type":"journal"},{"url":"https://link.springer.com/content/pdf/10.1007/s10735-026-10846-8.pdf","host_type":"publisher"},{"url":"https://link.springer.com/article/10.1007/s10735-026-10846-8","host_type":"publisher"},{"url":"https://doi.org/10.1007/s10735-026-10846-8","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/42257759","host_type":"repository"},{"url":"https://pmc.ncbi.nlm.nih.gov/articles/PMC13246569/","host_type":"repository"},{"url":"https://europepmc.org/articles/PMC13246569","host_type":"Europe_PMC"},{"url":"https://europepmc.org/articles/PMC13246569?pdf=render","host_type":"Europe_PMC"}],"fields_of_study":["RNA modifications and cancer","Sirtuins and Resveratrol in Medicine","Bone Metabolism and Diseases","Animals","Female","Ovariectomy","Osteoporosis","Plant Extracts","Cuscuta","Mice","Valosin Containing Protein","Methyltransferases","Proteolysis","Mesenchymal Stem Cells","Osteogenesis","Ubiquitination","Mice, Inbred C57BL","Cell Differentiation"],"mesh_terms":["Valosin Containing Protein","Animals","Cell Differentiation","Female","Methyltransferases","Mice, Inbred C57BL","Osteogenesis","Osteoporosis","Ovariectomy","Plant Extracts","Cuscuta","Mice","Ubiquitination","Mesenchymal Stem Cells","Proteolysis"],"keywords":["MG132","Gene knockdown","Ubiquitin","Bisphosphonate","Cycloheximide","Bone remodeling","Proteasome","Mesenchymal stem cell","Osteoporosis","Protein degradation","Cuscuta chinensis Lam. extract","Bard1","Mettl3","Vcp"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[{"name":"gen"},{"name":"doi"}],"source":"live","citation_network_status":"fetched"},"created_at":"2026-08-09T10:02:38.658986Z","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":[]}
