In this study, we explored the mechanism of ferroptosis related genes in the pathogenesis of PCOS using comprehensively bioinformatics method. Methods: Multiple bioinformatic methods were performed, such as differential expression analysis, least absolute shrinkage selection operator (LASSO) regression, support vector machine (SVM-RFE), survival analysis, receiver operator characteristic curve (ROC) analysis, decision curve analysis (DCA), drug sensitivity analysis, nomogram model and ceRNA network construction. Results: GSE5850, GSE34526 and GSE102293 datasets were downloaded from the Gene Expression Omnibus (GEO) database. Five genes, including NOX1, ACVR1B, PHF21A, FTL and GALNT14, were identified and used to construct a PCOS diagnostic model. Drug sensitivity analysis indicated that six drugs or molecular compounds were found to interact with GALNT14 or NOX1. Finally, a ceRNA network including 117 lncRNAs, 67 miRNAs and the 5 ferroptosis related genes was constructed. Conclusions: Our study identified a 5- ferroptosis related genes that might be involved in the pathogenesis of PCOS, which may provide a novel perspective for clinical diagnosis and treatment of PCOS.
