Exceptional longevity of ovarian and oocyte macromolecules throughout the reproductive lifespan of mammals

ABSTRACT: The mechanisms contributing to age-related deterioration of the female reproductive system are complex but aberrant protein homeostasis is a major contributor. We elucidated the exceptionally stable proteins, structures, and macromolecules that persist in ovaries and gametes throughout the reproductive aging timeline in mammals. Ovaries exhibit localized structural and cell-type specific enrichment of stable macromolecules throughout both the follicular and extrafollicular environments. Moreover, both ovaries and oocytes harbor a panel of exceptionally long-lived proteins, including cytoskeletal components, mitochondrial, and oocyte-derived proteins. The exceptional persistence of these long-lived molecules might play a critical role in both lifelong maintenance and age-dependent deterioration of reproductive tissues.

The maintenance of oocytes in the mammalian ovary involves extreme protein longevity

Project description:In mammals, oocytes are formed in the female embryo and need to be preserved in the ovary to ensure the viability of the next generation. How oocytes are maintained for decades is unclear. Here, we combined pulse-chase stable isotope labelling coupled with mass spectrometry, single-cell RNA-seq, microscopy and NanoSims to create an atlas of protein homeostasis in mouse oocytes and ovaries over the entire reproductive lifespan. Our results show that protein turnover in the ovary is much slower than in other organs, with hundreds of extremely long-lived proteins across a broad range of complexes and pathways, including mitochondria, ribosomes and the cytoskeleton. We propose that slow protein turnover helps to maintain proteostasis in oocytes and the ovary over long periods, protecting the germline across generations.

Polyamine metabolite spermidine rejuvenates the oocyte quality by enhancing mitophagy during female reproductive aging

Project description:Advanced age is a primary risk factor for female infertility due to reduced ovarian reserve and declining oocyte quality. However, as an important contributing factor, the role of metabolic regulation during reproductive aging is poorly understood. Here, we applied untargeted metabolomics to identify spermidine as a critical metabolite in ovaries to protect oocytes against aging. In particular, we found that spermidine level was reduced in aged ovaries and supplementation of spermidine promoted follicle development, oocyte maturation, early embryonic development and female fertility of aged mice. By micro-transcriptomic analysis, we further discovered that recovery of oocyte quality by spermidine was mediated by enhancement of mitophagy activity and mitochondrial function in aged mice, and this action mechanism was conserved in porcine oocytes under oxidative stress. Altogether, our findings demonstrate that spermidine supplementation is a potentially effective strategy to ameliorate oocyte quality and reproductive outcome of women at an advanced age.

Single-oocyte transcriptome analysis reveals aging-associated effects influenced by life stage and calorie restriction

Project description:Chromosome segregation errors in oocytes lead to the production of aneuploid eggs, which are the leading cause of pregnancy loss and of several congenital diseases such as Down syndrome. The frequency of chromosome segregation errors in oocytes increases with maternal age, especially at a late stage of reproductive life. How aging at various life stages affects oocytes differently remains poorly understood. In this study, we describe aging-associated changes in the transcriptome profile of mouse oocytes throughout reproductive life. Our single-oocyte comprehensive RNA sequencing using RamDA-seq revealed that oocytes undergo transcriptome changes at a late reproductive stage, whereas their surrounding cumulus cells exhibit transcriptome changes at an earlier stage. Calorie restriction, a paradigm that reportedly prevents aging-associated egg aneuploidy, promotes a transcriptome shift in oocytes with the up-regulation of genes involved in chromosome segregation. This shift is accompanied by the improved maintenance of chromosomal cohesin, the loss of which is a hallmark of oocyte aging and causes chromosome segregation errors. These findings have implications for understanding how oocytes undergo aging-associated functional decline throughout their reproductive life in a context-dependent manner.

Lhx8 ablation leads to massive autophagy of mouse oocytes associated with DNA damage

Project description:Following proliferation of oogonia inmammals, great numbers of germ cells are discarded, primarily by apoptosis, while the remainder form primordial follicles (the ovarian reserve) that determine fertility and reproductive lifespan. More massive, rapid, and essentially total loss of oocytes, however, occurs when the transcription factor Lhx8 is ablated—though the cause and mechanism of germ cell loss from the Lhx8-/- ovaries has been unknown. We found that Lhx8−/− ovaries maintain the same number of germ cells throughout embryonic development; rapid decrease in the pool of oocytes starts shortly before birth. The loss results from activation of autophagy, which becomes overwhelming within the first postnatal week, with extracellular matrix proteins filling the space previously occupied by follicles to produce a fibrotic ovary. Associated with this process, as early as a few days before birth, Lhx8-/- oocytes failed to repair DNA damage—which normally occurs when meiosis is initiated during embryonic development; and DNA damage repair genes were downregulated throughout the oocyte short lifespan. Based on gene expression analyses and morphological changes, we propose a model in which lineage-restricted failure of DNA repair triggers germ cell autophagy, causing premature depletion of the ovarian reserve in Lhx8-/- mice

Immature follicular origins and disrupted oocyte growth pathways contribute to decreased gamete quality during reproductive juvenescence in mice

Project description:Egg quality dictates fertility outcomes, and although there is a well-documented decline with advanced reproductive age, how it changes during puberty is less understood. Such knowledge is critical, since advances in Assisted Reproductive Technologies are enabling pre- and peri-pubertal patients to preserve fertility in the medical setting. Therefore, we investigated egg quality parameters in a mouse model of the pubertal transition or juvenescence (postnatal day; PND 11-40). Animal weight, vaginal opening, serum inhibin B levels, oocyte yield, oocyte diameter, and zona pellucida thickness increased with age. After PND 15, there was an age-associated ability of oocytes to resume meiosis and reach metaphase of meiosis II (MII) following in vitro maturation (IVM). However, eggs from the younger cohort (PND 16-20) had significantly more chromosome configuration abnormalities relative to the older cohorts and many were at telophase I instead of MII, indicative of a cell cycle delay. Oocytes from the youngest mouse cohorts originated from the smallest antral follicles with the fewest cumulus layers per oocyte, suggesting a more developmentally immature state. RNA Seq analysis of oocytes from mice at distinct ages revealed that the genes involved in cellular growth signaling pathways (PI3K, mTOR, and Hippo) were consistently repressed with meiotic competence, whereas genes involved in cellular communication were upregulated in oocytes with age. Taken together, these data demonstrate that gametes harvested during the pubertal transition have low meiotic maturation potential and derive from immature follicular origins.

Female Infertility: Primary ovarian insufficiency

Project description:<p>Premature ovarian failure, or primary ovarian insufficiency (POI) is a phenotype of diminished or absent ovarian function occurring in 1-2% of reproductive aged women. Most cases occur spontaneously. Evaluation of the gametes in women with POI is difficult and invasive. Practitioners must often rely on indirect biomarkers of ovarian function and oocyte health, making it difficult to identify patients who may benefit from therapies allowing them to achieve pregnancy utilizing their own oocytes. This study will generate exome sequences from POI patients in an effort to elucidate the causes of unexplained POI and to better understand the normal processes of ovarian aging. A better understanding of the genetics of ovarian function may lead to new non-invasive tools for managing women's reproductive health, and direct better use of existing biomarkers in diagnosis, screening and predicting clinical outcomes. </p>

Expression data of age-specific ovaries in rhesus monkey

Project description:The biological function of human ovaries declines with increasing age. Moreover, disorders that cause reproductive failure, such as premature ovarian failure (POF), seriously affect the female health and may be related to abnormal gene expression in the ovaries. The objective of this study was to generate the gene expression proM-oM-,M-^Ales of ovaries in rhesus monkeys of different ages, so as to identify age-related changes in the ovaries and understand their significance in various human reproductive problems. Ovaries were obtained from young (Y, 3 to 4 years), middle-age (M, 7 to 8 years) and old (O, 18 to 19 years) monkeys, and each group had 3 monkey replications. Half of ovary from each monkey was isolated mRNA for whole genome gene expression microarray analysis to detect differentially expressed genes, and followed by the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses by using a free web-based Molecular Annotation System 3.0 (MAS 3.0).

Effects of the sex chromosome complement, XX, XO or XY, on the transcriptome and development of mouse oocytes during follicular growth.

Project description:Purpose: To understand how sex chromosome complement, XX, XO and XY, influences the transcriptome in the oocytes of grwoth phase. Methods: Oocytes of 50 and 60 µm in diameter were isolated from mouse ovaries at 18 dpp and subject to RNA-sequencing. Results: (1) Many X-linked genes are subject to X chromosome dosage dependent expression. (2) Many genes are expressed from both short and long arms of the Y chromosome. (3) The transcriptome landscape in XY oocytes is closer to XX oocytes than XO oocytes. (4) About 10 genes are differentially expressed in XY oocytes compared to XX or XO oocytes. Conclusions: The differences in XY oocytes became exacerbated to differ from XX or XO oocytes near the end of growth phase.

Inactivation of Exosc10 in the oocyte impairs oocyte development and maturation, leading to a depletion of the ovarian reserve in mice.

Project description:EXOSC10 is a catalytic subunit of the nuclear RNA exosome with an exoribonuclease activity. The enzyme processes and degrades different classes of RNAs. To delineate the role of EXOSC10 during oocyte growth, specific Exosc10 inactivation was performed in the oocytes from the primordial follicle stage onward using the Gdf9-iCre; Exosc10f/- mouse model (Exosc10cKO(Gdf9)). Exosc10cKO(Gdf9) female mice are infertile. The onset of puberty and the estrus cycle in mutants are initially normal and ovaries contain all follicle classes. By the age of eight weeks, vaginal smears reveal irregular estrus cycles and mutant ovaries display a complete depletion of follicles. Mutant oocytes retrieved from the oviduct are degenerated, sometimes showing an enlarged polar body which may reflect a defective first meiotic division. Under fertilization conditions, the mutant oocytes do not enter into an embryonic development process. Furthermore, we conducted a comparative proteome analysis of wild type and Exosc10 knockout mouse ovaries and identified EXOSC10-dependent proteins involved in many biological processes, such as meiotic cell cycle progression and oocyte maturation. Our results unambiguously demonstrate an essential role for EXOSC10 in oogenesis and may serve as a model for primary ovarian insufficiency in humans.
