This study aimed to explore the role of miR-16-5p and ANLN in breast cancer (BC).\nMETHODS: Cohort datasets of BC were obtained from the Gene Expression Omnibus (GEO) and the Cancer Genome Atlas (TCGA) and analyzed by bioinformatics tools. qRT-PCR and western blotting were applied to validate ANLN and its protein expression. A dual-luciferase reporter assay was used to prove the regulatory relationship of miR-16-5p and ANLN. Finally, MTT, wound healing, Transwell invasion and flow cytometry analyses of the cell cycle and apoptosis were performed to assess cell proliferation, migration, invasion, cell cycle and apoptosis, respectively.\nRESULTS: A total of 195 differentially expressed genes (DEGs) and 50 overlapping microRNAs (miRNAs) were identified. Among these DEGs and miRNAs, ANLN, associated with poor overall survival in BC, overlapped in the GSE29431, GSE42568, TCGA and GEPIA2 databases. Moreover, ANLN was highly expressed, while miR-16-5p was lower in BC cells than in breast epithelial cells. Then, we confirmed that ANLN was directly targeted by miR-16-5p in BC cells. Over-expression of miR-16-5p and knock-down of ANLN remarkably inhibited cell proliferation and migration as well as cell invasion, arrested the cells in G2/M phase and induced apoptosis in BC cells.\nCONCLUSIONS: These findings suggest that miR-16-5p restrains proliferation, migration and invasion while affecting cell cycle and promotes apoptosis by regulating ANLN, thereby providing novel candidate biomarkers for the diagnosis and treatment of BC.", "claims": [{"id": "claim-method", "statement": "Through applying limma package, FDR < 0.05 and |logFC| > 1.5 [24, 25] were set as the screening threshold values to identify differentially expressed genes (DEGs) from GSE86374.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:34743685", "locator": "sections[3] \"Data sources and processing and identification of DEGs\" paragraph 2", "quote": "Through applying limma package, FDR < 0.05 and |logFC| > 1.5 [24, 25] were set as the screening threshold values to identify differentially expressed genes (DEGs) from GSE86374."}], "state": "complete"}, {"id": "claim-data-access", "statement": "The datasets of BC in this study were downloaded from the GEO and UCSC Xena (https://www.ncbi.nlm.nih.gov/geo/; https://xenabrowser.net/datapages/) databases.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:34743685", "locator": "sections[34] \"notes\" paragraph 1", "quote": "The datasets of BC in this study were downloaded from the GEO and UCSC Xena (https://www.ncbi.nlm.nih.gov/geo/; https://xenabrowser.net/datapages/) databases."}], "state": "complete"}, {"id": "claim-target-result", "statement": "These findings suggest that miR-16-5p restrains proliferation, migration and invasion while affecting cell cycle and promotes apoptosis by regulating ANLN, thereby providing novel candidate biomarkers for the diagnosis and treatment of BC.", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:34743685", "locator": "sections[0] \"Abstract\" paragraph 4", "quote": "These findings suggest that miR-16-5p restrains proliferation, migration and invasion while affecting cell cycle and promotes apoptosis by regulating ANLN, thereby providing novel candidate biomarkers for the diagnosis and treatment of BC."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "complete", "objective": "These findings suggest that miR-16-5p restrains proliferation, migration and invasion while affecting cell cycle and promotes apoptosis by regulating ANLN, thereby providing novel candidate biomarkers for the diagnosis and treatment of BC.", "steps": [{"id": "read_published_estimate", "order": 1, "name": "Read the published estimate from the source", "kind": "other", "state": "complete", "blocked_on": null, "description": "The claim, method and evidence span published with the source article.", "duration_hours": null, "parameters": {}, "inputs": ["source:pmid:34743685"], "outputs": ["the published estimate and its evidence"], "instruments": [], "reagents": []}, {"id": "obtain_source_data", "order": 2, "name": "Obtain the source data from the named repository", "kind": "data-preparation", "state": "complete", "blocked_on": null, "description": "The GEO series accession resolves and its sample accessions are listed.
