Abstract The ovary ages earlier than most other tissues, yet the underlying mechanisms remain elusive. Here a comprehensive analysis of transcriptomic landscapes in different organs young and middle-aged mice revealed that ovaries showed expression age-associated genes, identifying increased NADase CD38 decreased NAD + levels mice. Bulk single-cell RNA sequencing deletion mitigated ovarian aging, preserving fertility follicle reserve aged by countering age-related gene changes intercellular communication alterations. Mechanistically, onset inflammation induced higher ovary, thereby accelerating aging. Consistently, pharmacological inhibition enhanced Our findings aging relative to organs, providing potential therapeutic target for ameliorating female infertility.

Ovarian aging occurs earlier than the of many other organs and has a lasting impact on women's overall health well-being. However, effective interventions to slow ovarian remain limited, primarily due an incomplete understanding underlying molecular mechanisms drug targets. Recent advances in omics data resources, combined with innovative computational tools, are offering deeper insight into complexities aging, paving way for new opportunities discovery development. This review aims synthesize expanding multi-omics data, spanning genome, transcriptome, proteome, metabolome, microbiome, related from both tissue-level single-cell perspectives. We will specially explore how analysis these emerging datasets can be leveraged identify novel targets guide therapeutic strategies slowing reversing aging. conducted comprehensive literature search PubMed database using range relevant keywords: age at natural menopause, premature insufficiency (POI), diminished reserve (DOR), genomics, transcriptomics, epigenomics, DNA methylation, RNA modification, histone proteomics, metabolomics, lipidomics, single-cell, genome-wide association studies (GWAS), whole-exome sequencing, phenome-wide (PheWAS), Mendelian randomization (MR), epigenetic target, machine learning, artificial intelligence (AI), deep multi-omics.

Abstract Nicotinamide adenine dinucleotide (NAD+), a crucial coenzyme in cellular redox reactions, is closely associated with age-related functional degeneration and metabolic diseases. NAD exerts direct indirect influences on many functions, including pathways, DNA repair, chromatin remodeling, senescence, immune cell functionality. These processes functions are essential for maintaining tissue homeostasis, as well healthy aging. Causality has been elucidated between decline levels multiple diseases, which confirmed by various strategies aimed at increasing the preclinical setting. Ovarian aging recognized natural process characterized follicle number function, resulting decreased estrogen production menopause. In this regard, it necessary to address factors involved complicated procedure, could improve fertility women of advanced maternal age. Concerning decrease NAD+ ovarian progresses, promising exciting results presented using precursors promote biosynthesis, substantially oocyte quality alleviate Hence, acquire further insights into metabolism biology, review aims probe affecting aging, characteristics precursors, current research status supplementation Specifically, gaining comprehensive understanding these aspects, we optimistic about prominent progress that will be made both therapy related

Abstract This review explores the relationship between ovarian aging and senescent cell accumulation, as well efficacy of senolytics to improve reproductive longevity. Reproductive longevity is determined by age-associated decline in reserve, resulting reduced fertility eventually menopause. Cellular senescence a state permanent cycle arrest resistance apoptosis. Senescent cells accumulate several tissues with advancing age, thereby promoting chronic inflammation age-related diseases. Ovaries also appear which might contribute system whole organism through SASP production. Importantly, senolytic drugs can eliminate may present potential intervention mitigate aging. Herein, we current literature related for extending window mice.

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

Astragalin (AG), a typical flavonoid found in Thesium chinense Turcz (T. chinense), is abundant various edible plants and possesses high nutritional value, as well antioxidant antibacterial effects. In this study, we initially predicted the mechanism of action AG with two anti-aging antioxidant-related protein targets (CD38 IGFR) by molecular docking dynamics simulation techniques. Subsequently, examined effects Caenorhabditis elegans (C. elegans), zebrafish, verified related mechanisms. C. elegans, synergistically extended lifespan up-regulating expression daf-16 through inhibiting daf-2/IGFR also activating AMPK MAPK pathways to up-regulate sir-2.1, sir-2.4, skn-1. oxidatively damaged zebrafish embryos, demonstrated synergistic effect augmenting resistance embryos oxidative stress levels SIRT1 SIRT6 within system via suppression CD38 enzymatic activity then IGFR SIRT6. These findings highlight properties indicate its potential application supplementary ingredient aquaculture for enhancing fish health growth.

Abstract Natural Nicotinamide Adenine Dinucleotide (NAD + ) precursors have attracted much attention due to their positive effects in promoting ovarian health. However, target tissue, synthesis efficiency, advantages, and disadvantages are still unclear. This review summarizes the distribution of NAD at cellular subcellular levels, discusses its biosynthetic pathways latest findings ovary, include: (1) plays distinct roles both intracellularly extracellularly, adapting response requirements. (2) Different differs tissues, synthetic biological utilization, adverse effects. Importantly: tryptophan is primarily utilized liver kidneys, posing metabolic risks excess; nicotinamide (NAM) indispensable for maintaining levels; nicotinic acid (NA) constructs a crucial bridge between intestinal microbiota host with diverse functions; riboside (NR) mononucleotide (NMN) increase systemically can be influenced by delivery route, tissue specificity, transport efficiency. (3) The intricately intertwined. They provide multiple sources techniques synthesis, thereby reducing dependence on single molecule maintain levels. an excess specific precursor potentially influencing other pathways. In addition, Protein expression analysis suggest that tissues may preferentially utilize NAM NMN. These summarize potential enhancing Future research should delve into molecular mechanisms intervention strategies different precursors, aiming achieve personalized prevention or treatment diseases, reveal clinical application value.
