It is characterized by symptoms such as hyperandrogenemia, oligo or anovulation and polycystic ovarian, significantly impacting quality of life. However, the practical implementation of machine learning (ML) in PCOS diagnosis is hindered by the limitations related to data size and algorithmic models. To address this research gap, we have increased the sample size in our study and aim to utilize two ML algorithms to analyze and validate diagnostic biomarkers, as well as explore immune cell infiltration patterns in PCOS.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;We performed RNA-seq analysis on granulosa cell, including 13 samples from normal controls and 25 samples from women with PCOS. The data from our study were combined with publicly available databases. Batch effects were corrected using the 'sva' package in R software. Differential expression analysis was performed to identify genes that exhibited significant differences between the two groups. These differentially expressed genes (DEGs) were further analyzed for Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. Hub genes were selected by intersecting the results of both methods after using LASSO and SVM-RFE for central gene selection for DEGs. Receiver Operating Characteristic (ROC) curves were employed to verify the accuracy of models by SVM and XGBoost. CIBERSORT analysis was performed to determine the relative abundances of immune cell populations. GSEA was analyzed to illustrate the expression patterns of genes within highly enriched functional pathways. RT-qPCR was used to validate the reliability of hub genes.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;824 DEGs were found between the normal control and PCOS groups, including 376 upregulated and 448 downregulated genes. These DEGs were associated with endocytosis, salmonella infection and focal adhesion based on the KEGG enrichment analysis. Through overlapping LASSO and SVM-RFE algorithms, we identified four hub genes (CNTN2, CASR, CACNB3, MFAP2) that are significantly associated with the PCOS group. The diagnostic efficacy validation set using SVM and XGBoost yielded AUC values of 0.795 and 0.875, respectively, indicating their potential as diagnostic biomarkers. Consistent with the data analysis, the upregulation of CNTN2, CASR, CACNB3, and MFAP2 in PCOS was confirmed by RT-qPCR analysis on human granulosa cells.

However, its molecular mechanisms are unclear. This study aimed to investigate the molecular mechanisms of HSYLF and clarify how network pharmacology analysis guides the design of animal experiments, including the selection of effective treatment doses and key targets, to ensure the relevance of the experimental results.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;Network pharmacology, molecular docking, and animal experiments were utilized to investigate the effects of HSYLF. Key targets were identified by intersecting herb and disease targets to construct protein-protein interaction and \"active components-intersection targets-disease\" networks. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes pathway analyses were performed using the clusterProfiler package in R. A total of 50 specific pathogen-free female mice of reproductive age were included in the animal experiments. They were divided into five groups: the positive control group, the high-dose HSYLF group, the low-dose HSYLF group, the model blank group, and the normal control group, to evaluate the serum anti-müllerian hormone levels, mitochondrial morphology in oocytes, the levels of reactive oxygen species (ROS), and mitochondrial membrane potential.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Network pharmacology identified 204 active components connecting 219 key therapeutic targets for POI. Gene Ontology enrichment analysis indicated that the anti-POI targets of HSYLF mainly regulated response to xenobiotic stimulus, cellular response to chemical stress, and response to oxidative stress; and the Kyoto Encyclopedia of Genes and Genomes pathway analysis suggested the primary pathways, including lipid and atherosclerosis, advanced glycation end product-receptor for advanced glycation end product signaling pathway in diabetic complications, bladder cancer, tumor necrosis factor signaling pathway, and interleukin-17 signaling pathway. The low-dose (33 g/kg/d) HSYLF and high-dose (66 g/kg/d) HSYLF groups exhibited a marked elevation in serum anti-müllerian hormone levels (low-dose group: 2657.63 ± 354.82 PG/ml; high-dose group: 2823.73 ± 316.04 PG/ml) and mitochondrial membrane potential compared to the model blank group (P &lt; 0.05 or P &lt; 0.01), along with a significant decline in fluorescence intensity of 2',7'-dichlorofluorescein for the levels of ROS in oocytes (P &lt; 0.05 or P &lt; 0.01). Additionally, both groups showed varying degrees of improvement in the morphology, quantity, and distribution of mitochondria.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Conclusion: &lt;/strong&gt;This study provides definite evidence for the molecular mechanism by which HSYLF treats POI by decreasing mitochondrial ROS, increasing membrane potential, and improving mitochondrial function.

In our study, we sought to determine whether miRNAs in the ULF are differentially expressed between women with and without endometriosis and to uncover the association of miRNAs with the development potential of blastocysts. The implantation and clinical pregnancy rates significantly decreased in women with endometriosis than in those without endometriosis.

In addition, the AIT-PCOS group had significantly higher serum IgG3 levels than the other three groups. Binary logistic regression analysis revealed that the PDIA3Ab total IgG level was an independent risk factor for concurrent PCOS in euthyroid AIT women (Q4 vs. Q1: OR, 95%CI = 5.082, 1.348-19.16). Furthermore, a trend test demonstrated a titer-dependent increase in PCOS prevalence among AIT women as the PDIA3Ab total IgG level increased.</p><p><strong>Conclusions: </strong>The expression of serum PDIA3Ab may indicate an increased risk of PCOS in euthyroid AIT women and could potentially serve as new targets for markers or immune intervention.</p>","PeriodicalId":16610,"journal":{"name":"Journal of Ovarian Research","volume":"17 1","pages":"247"},"PeriodicalIF":3.8,"publicationDate":"2024-12-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11656784/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142864553","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
