The dataset GSE36961 was retrieved from Gene Expression Omnibus (GEO) database and comprehensive bioinformatics was employed to identify the core genes linked to sex differences in HCM patients. Additionally, gene set enrichment analysis (GSEA) was conducted to detect downstream signalling pathways. Furthermore, experimental validation was carried out using hearts from spontaneously hypertensive rats (SHRs). A comprehensive analysis revealed the identification of 208 differentially expressed genes (DEGs) in female patients with HCM with a notable downregulation of seven core genes. Notably, there were sex differences in the expression of ras dexamethasone-induced protein 1 (RASD1) and myosin 6 (MYH6) in HCM. Gene ontology (GO) analysis and GSEA demonstrated an enrichment of autophagy-related processes in disease progression in HCM females. Specifically, spearman's correlation analysis revealed a positive correlation between nicotinamide phosphoribosyl transferase (NAMPT) and RASD1 levels, particularly among female patients (R = 0.569, p < 0.001). Additionally, animal models confirmed that cardiac hypertrophy was more pronounced in SHR females compared to males. SHR females exhibited lower mRNA and protein expressions of RASD1 and NAMPT, which were associated with impaired autophagy. In this study, bioinformatics and validation using external data sets and animal models of left ventricular hypertrophy suggested that the RASD1/NAMPT axis is potentially a crucial mechanism underlying the elevated risk of cardiovascular disorders in HCM females, also pointing potentially prognostic biomarkers.", "claims": [{"id": "claim-method", "statement": "To investigate the impact of autophagy on sex differences in HCM, we employed Spearman's correlation analysis to identify correlations between the expressions of core genes and autophagy‐related genes obtained from the Human Autophagy Database.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:39535387", "locator": "sections[8] \"Spearman's correlation analysis\" paragraph 2", "quote": "To investigate the impact of autophagy on sex differences in HCM, we employed Spearman's correlation analysis to identify correlations between the expressions of core genes and autophagy‐related genes obtained from the Human Autophagy Database."}], "state": "complete"}, {"id": "claim-data-access", "statement": "The open‐access datasets are available through the following URL: https://www.ncbi.nlm.nih.gov database annotated by GPL10558 as a Series Matrix File.", "kind": "methodological", "target": null, "evidence": [{"asset": "source:pmid:39535387", "locator": "sections[28] \"DATA AVAILABILITY STATEMENT\" paragraph 2", "quote": "The open‐access datasets are available through the following URL: https://www.ncbi.nlm.nih.gov database annotated by GPL10558 as a Series Matrix File."}], "state": "complete"}, {"id": "claim-target-result", "statement": "A comprehensive analysis revealed the identification of 208 differentially expressed genes (DEGs) in female patients with HCM with a notable downregulation of seven core genes.", "kind": "qualitative", "target": null, "evidence": [{"asset": "source:pmid:39535387", "locator": "sections[0] \"Abstract\" paragraph 1", "quote": "A comprehensive analysis revealed the identification of 208 differentially expressed genes (DEGs) in female patients with HCM with a notable downregulation of seven core genes."}], "state": "complete"}], "gaps": []}, "experiment": {"state": "complete", "objective": "A comprehensive analysis revealed the identification of 208 differentially expressed genes (DEGs) in female patients with HCM with a notable downregulation of seven core genes.", "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:39535387"], "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.
