The relationship between circulating metabolites and prostate hyperplasia: a Mendelian randomization study.

Area of Science:

• Metabolomics
• Genetic Epidemiology
• Urology

Background:

• Circulating metabolites (CM) are crucial for health, but their role in benign prostatic hyperplasia (BPH) is not well understood.
• Mendelian randomization (MR) is a valuable method for investigating causal relationships between exposures and outcomes.

Purpose of the Study:

• To explore the potential impact of circulating metabolites on benign prostatic hyperplasia (BPH) risk using a bidirectional Mendelian randomization approach.
• To identify specific metabolic pathways and compounds associated with BPH.

Main Methods:

• A forward Mendelian randomization (MR) analysis examined 249 circulating metabolites as exposures for BPH risk.
• A reverse MR analysis investigated BPH as an exposure to determine its effects on circulating metabolites.
• Statistical methods were employed to exclude heterogeneity and pleiotropy.

Main Results:

• Forward MR identified six circulating metabolites associated with BPH risk.
• Reverse MR indicated that nine metabolic compounds, primarily phospholipids and triglycerides, are potentially elevated in BPH patients.
• These findings suggest a significant interplay between specific metabolites and BPH development.

Conclusions:

• Bidirectional MR analysis provides genetic evidence for the association between circulating metabolites and BPH.
• Lipids and triglycerides are highlighted as key metabolic factors intricately linked to BPH risk.
• Further research into these metabolic pathways could inform BPH prevention and treatment strategies.
