Over the decade, the incidence of reproductive disorders has become a significant source of suffering for women. Infertility in women may be caused by a range of acquired and congenital abnormalities. Ovaries play a central role in the female reproductive function. Any defect in the normal functioning of these endocrine organs causes health issues and reproductive challenges extending beyond infertility, as the hormones interact with other tissues and biological processes in the body. The complex pathophysiology of ovarian disorders makes it a multifactorial disease. The key etiological factors associated with the diseases include genetic factors, hormonal imbalance, environmental and lifestyle factors, inflammatory conditions, oxidative stress, autoimmune diseases, metabolic factors, and age. Oxidative stress is a major contributor to disease development and progression affecting the oocyte quality, fertilization, embryo development, and implantation. The choice of treatment for ovarian disorders varies among individuals and has associated complications. Reproductive tissue engineering holds great promise for overcoming the challenges associated with the current therapeutic approach to tissue regeneration. Furthermore, incorporating nanotechnology into tissue engineering could offer an efficient treatment strategy. This review provides an overview of incorporating antioxidant nanomaterials for engineering ovarian tissue to address the disease recurrence and associated pathophysiology. Cerium oxide nanoparticles (CeO₂ NPs) are prioritized for evaluation primarily due to their antioxidant properties. In conclusion, the review explores the potential applications of CeO₂ NPs for effective and clinically significant ovarian tissue regeneration.</p>","PeriodicalId":16610,"journal":{"name":"Journal of Ovarian Research","volume":"17 1","pages":"241"},"PeriodicalIF":3.8,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11619646/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142780398","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}

This study aims to deepen the understanding of HGSOC by characterizing mRNA subtypes and examining their immune microenvironment (TIME) and its role in disease progression. Using transcriptomic data and an advanced computational pipeline, we investigated four mRNA subtypes: immunoreactive, differentiated, proliferative, and mesenchymal, each associated with distinct gene expression profiles and clinical behaviors. We performed differential expression analysis among mRNA subtypes using DESeq2 and conducted Weighted Gene Co-Expression Network Analysis (WGCNA) to identify co-expressed gene modules related to clinical traits, e.g., age, survival, and subtype classification. Gene Ontology (GO) analysis highlighted key pathways involved in tumor progression and immune evasion. Additionally, we utilized TIMER 2.0 to assess immune cell infiltration across different HGSOC subtypes, providing insights into the interplay between tumor immune microenvironment (TIME). Our findings show that the immunoreactive subtype, particularly the M3 module-associated network, was marked by high immune cell infiltration, including M1 (p < 0.0001) and M2 macrophages (p < 0.01), and Th1 cells (p < 0.01) along with LAIR-1 expression (p = 1.63e-101). The M18 module exhibited strong B cell signatures (p = 6.24e-28), along with significant FCRL5 (adj. p = 3.09e-30) and IRF4 (adj. p = 3.09e-30) coexpression. In contrast, the M5 module was significantly associated with the mesenchymal subtype, along with fibroblasts (p < 0.0001). The proliferative subtype was characterized by M15 module-driven cellular growth and proliferation gene expression signatures, along with significant ovarian stromal cell involvement (p < 0.0001).

The causes of POI are heterogeneous, but substantial evidence exists to support a genetic basis of POI, particularly in the critical involvement of genes on the X chromosome. Recent studies have revealed novel candidate genes through the identification of copy number variations associated with POI. This review summarizes the genes located on the X chromosome with variants shown to be associated with POI in humans and/or in mice. Additionally, we present evidence to support the potential involvement of these candidate genes in the etiology of POI. We conducted a literature search in PubMed to identify case studies and screenings for the genetic causes of POI. We then performed systematic searches for the proposed candidate genes to investigate their potential reproductive roles. Of the X-linked candidate genes investigated, 10 were found to have variants associated with cases of POI in humans. An additional 10 genes were found to play a supportive role in POI. Other genes were not implicated in any cases of POI but were associated with various roles in reproduction. In the majority of cases where variants were identified through whole-exome sequencing, rather than targeted screening of candidate genes, more than one genetic variant was identified. Overall, this review supports past findings that the X chromosome plays a critical role in ovarian function, as demonstrated by a link between POI and various disruptions to genes on the X chromosome. Current genetic screening for POI, which includes only FMR1, is inadequate to capture the majority of cases with a genetic origin. An expanded genetic testing may improve health outcomes for individuals with POI as it could lead to better early interventions and education about these health risks.</p>","PeriodicalId":16610,"journal":{"name":"Journal of Ovarian Research","volume":"17 1","pages":"238"},"PeriodicalIF":3.8,"publicationDate":"2024-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11603650/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142751048","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}
