Project description:Background: The outbreak of coronavirus disease 2019 (COVID-19) poses a considerable health threat to humanity, with potential implications for the ovarian microenvironment remaining uncertain. Methods: Transcriptomic and proteomic analyses of ovarian granulosa cells, along with metabolomic and lipidomic profiling of follicular fluid, were conducted on 17 non-COVID-19 cases and 9 COVID-19 cases. This study received approval from the ethics committee (KYLL-2022-581). Generalized estimating equations model was performed to identify oocyte competency biomarkers. Additionally, cell proliferation, apoptosis, and altered pathways were examined following lentivirus transfection.

Additionally, cell proliferation, apoptosis, and altered pathways were examined following lentivirus transfection. Conclusions: By integrating untargeted metabolomic and lipidomic features, we identified biomarkers indicative of oocyte competency influenced by COVID-19.

Project description:The mechanisms of oocyte meiotic defects and low competence during ovarian aging remains elusive for decades. Using Hi-C (genome-wide chromatin conformation capture) and Smart RNA-seq of oocytes from 6- weeks or 10- months aged ovaries, the abnormal loose chromatin structures and disturbing expression of meiosis associated genes at metaphase I phase were disclosed. Furthermore, the transcriptomic landscape of granulosa cells (GCs) surrounding oocytes from young and aged ovaries reveled that oocyte meiotic maturation was accompanied with a robust increased expression of genes involved with the mevalonate (MVA) pathway in GCs from young ovaries but these genes expression was not upregulated to counterpart level in GCs from aged ovaries.The inhibitor of MVA pathway of GCs, Statins significantly decreased polar body extrusion rate and increased the rate of irregularly assembled spindles and misaligned chromosomes remarkably in oocytes of culumus-oocyte complex (COCs) from young ovaries . Correspondingly, the activitor of MVA pathway of GCs, Geranylgeraniol ameliorated ovarian reserve and reduced meiotic defects in oocytes of COCs from aged ovaries. Mechanistically, MVA pathway activation in GCs culminated oocyte meiotic maturation by upregulating EGF signaling via LH receptor on GCs surrounding oocytes. Together, MVA pathway is a promising therapeutic target for prompting quality of oocytes from aged ovaries.
