Thus, nuclear maturation is accelerated ahead of the completion of cytoplasmic maturation. Dibutyryl-cAMP (dbcAMP), a well-known cAMP modulator, is used to inhibit the resumption of meiosis in immature oocytes. However, there is no information on the optimal timeframe for sustaining meiotic arrest to enhance oocyte maturity during IVM. To determine the optimal duration of meiotic arrest, immature cumulus–oocyte complexes (COCs) from MAFs were cultured with 1 mM dbcAMP for 0, 4, 8, 12, 16, or 22 h, followed by further IVM without dbcAMP for 44, 40, 36, 32, 28, or 22 h. Subsequently, nuclear maturation, cumulus cell expansion score, perivitelline space size, glutathione (GSH) and reactive oxygen species (ROS) levels, and preimplantation development of parthenogenetic and in vitro-fertilized embryos were assessed in oocytes from each group. The results showed that a 16-h treatment with 1 mM dbcAMP within the 44-h IVM process yielded the highest oocyte maturity. Accordingly, we established an advanced IVM protocol for producing oocytes with superior maturity from porcine MAFs by achieving nuclear maturation 36 h after initiating IVM, using a 16-h treatment with 1 mM dbcAMP within the 44-h IVM process.</div></div>","PeriodicalId":21018,"journal":{"name":"Reproductive biology","volume":"25 1","pages":"Article 100987"},"PeriodicalIF":2.5,"publicationDate":"2024-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142792569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, the discussions covered the environmental impact on reproductive function, as well as the development and function of the gonads. Additionally, two workshop events were organized: ‘Milestones on the road to a fruitful scientific career” for young researchers with a PhD degree, and “How to live with research failures and not be discouraged” for PhD students, which gave young researchers an opportunity to exchange their experience in the scientific field and discuss possible ways of handling crises.

This study explores the competitive endogenous RNA (ceRNA) regulatory network in the cumulus cells of PCOS patients. ceRNAs are transcripts like mRNAs, miRNAs, and lncRNAs that competitively bind shared miRNAs, regulating gene expression post-transcriptionally. We analyzed mRNA, microRNA (miRNA), and long non-coding RNA (lncRNA) from two cohorts: 12 PCOS patients and 11 healthy controls (dataset GSE10946), and 5 PCOS patients and 5 healthy controls (dataset GSE72274). These microarray datasets, obtained from the Gene Expression Omnibus (GEO), helped us identify differentially expressed mRNAs, miRNAs, and lncRNAs. Our analysis revealed a significant ceRNA network, which may play a crucial role in the pathophysiology of PCOS. In this network, 5 lncRNAs, 3 miRNAs, and 36 mRNAs were identified as differentially expressed. These elements form a complex regulatory schema influencing key cellular processes related to the disease, such as cell cycle regulation and response to estrogen. The HOXA11-AS-hsa-miR-454–3p-CCND2 network emerged as a potentially valuable biomarker for PCOS diagnosis, supported by Receiver Operating Characteristic (ROC) curve analysis indicating strong predictive power. Our findings suggest that the ceRNA interactions in PCOS cumulus cells provide a deeper understanding of the disease's molecular basis and offer new avenues for therapeutic intervention. This in silico study lays the groundwork for further experimental validation of these ceRNA networks as targets for PCOS treatment.</div></div>","PeriodicalId":21018,"journal":{"name":"Reproductive biology","volume":"25 1","pages":"Article 100916"},"PeriodicalIF":2.5,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142684098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
