Abstract
Using genome-wide association study data from European populations, this research clarifies the causal relationship between plasma metabolites and age-related macular degeneration (AMD) and employs Metabo Analyst 5.0 for enrichment analysis to investigate their metabolic pathways. Employing Mendelian randomization analysis, this study leveraged single nucleotide polymorphisms significantly associated with plasma metabolites as instrumental variables. This approach established a causal link between metabolites and AMD. Analytical methods such as inverse-variance weighted, Mendelian randomization-Egger, and weighted median were applied to validate causality. Mendelian Randomization Pleiotropy Residual Sum and Outlier was utilized for outlier detection and correction, and Cochran's Q test was conducted to assess heterogeneity. To delve deeper into the metabolic characteristics of AMD, metabolic enrichment analysis was performed using Metabo Analyst 5.0. These combined methods provided a robust framework for elucidating the metabolic underpinnings of AMD. The 2-sample MR analysis, after meticulous screening, identified causal relationships between 88 metabolites and AMD. Of these, 16 metabolites showed a significant causal association. Following false discovery rate correction, 3 metabolites remained significantly associated, with androstenediol (3 beta, 17 beta) disulfate (2) exhibiting the most potent protective effect against AMD. Further exploration using Metabo Analyst 5.0 highlighted 4 metabolic pathways potentially implicated in AMD pathogenesis. This pioneering MR study has unraveled the causal connections between plasma metabolites and AMD. It identified several metabolites with a causal impact on AMD, with 3 maintaining significance after FDR correction. These insights offer robust causal evidence for future clinical applications and underscore the potential of these metabolites as clinical biomarkers in AMD screening, treatment, and prevention strategies.

Integrated gut microbiota and fecal metabolome analyses of the effect of Lycium barbarum polysaccharide on D-galactose-induced premature ovarian insufficiency. Food Funct 2023; 14:7209-7221.

Abstract
Premature ovarian insufficiency (POI) has become one of the greatest health threats to the reproduction of women during their fertile age. Lycium barbarum polysaccharides (LBPs) are known for anti-aging and reproductive protective functions. Here, we investigated the protective effect of LBP on POI mice and revealed its possible mechanism by a combination of 16S rRNA sequencing and metabolomics analysis. In the current study, female C57BL/6J mice treated with D-galactose were used as a model to investigate the reversal effect of LBP on the degenerative ovarian function. The ameliorative effect of LBP on POI was evaluated from the estrous cycle, ovarian reserve, serum sex hormone levels, and fertility testing. Additionally, 16S rRNA gene sequencing and untargeted metabolomics were integrated to analyze the effects of LBP on the gut microbiota and fecal metabolic profile in the POI mice. The results showed that LBP administration significantly increased the total number of follicles and the number of follicles at different developmental stages in the POI mice. In addition, LBP was effective in reducing the serum levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), regularizing the disordered estrous cycle, and increasing the number of offspring of the POI mice. The results from 16S rRNA sequencing showed that LBP had beneficial effects on the composition and structure of the gut microbiota in the POI mice. In a metabolomics study, a total of 23 metabolites were finally identified as potential biomarkers of POI, and multiple pathways were regulated after the treatment of LBP, especially the arginine biosynthesis, glycerophospholipid metabolism and steroid hormone biosynthesis pathways. Pearson's correlation analysis showed that the regulation effect of LBP on metabolites was closely related to Faecalibaculum, Bilophila and Anaerofustis in the gut microbiota. In summary, the results demonstrated that LBP could improve the ovarian reserve and provides evidence both on the gut microbiota and metabolism, which provide beneficial support for the applications of LBP in female ovarian function degeneration.

[PMID: 37231423 DOI: 10.1186/s12905-023-02438-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/26/2022] [Accepted: 05/16/2023] [Indexed: 05/27/2023] Open
Abstract
INTRODUCTION Associations of luteinizing hormone (LH) with androgens during the menopausal transition and associations between follicle-stimulating hormone (FSH) levels and various diseases related to reproductive hormones in postmenopause have received much attention. LH and FSH are also known to be associated with activities of enzymes related to reproductive hormones. We examined the associations of LH and FSH with androgens and estrogens in each stage of the menopausal transition according to a classification from menopausal transition to postmenopause. METHODS This study was a cross-sectional design. We basically used the Stage of Reproductive Aging Workshop (STRAW) + 10. We divided the 173 subjects into 6 groups according to menstrual regularity and follicle-stimulating hormone level: mid reproductive stage (Group A), late reproductive stage (Group B), early menopausal transition (Group C), late menopausal transition (Group D), very early postmenopause (Group E) and early postmenopause (Group F). Levels of LH, FSH, dehydroepiandrosterone sulfate (DHEAS), estradiol, estrone, testosterone (T), free T, androstenedione and androstenediol were measured. RESULTS In Group A, LH showed significant positive correlations with androstenedione and estrone. In Group D, LH was positively associated with T and free T and was negatively associated with estradiol. In Groups B, C, D and F, LH showed significant positive correlations with FSH, and there was a tendency for an association between LH and FSH in Group E. FSH was associated with estradiol but not with estrone in Groups C and D. CONCLUSION The associations of LH and FSH with reproductive hormones are different depending on the stage of the menopausal transition.
