Summary
The human microbiome influences prostate cancer (PCa) development and treatment. Targeting the gut, urinary, and prostate microbiomes offers new avenues for PCa diagnostics and therapies.
Area of Science:
- Oncology
- Microbiology
- Genetics
Background:
- Prostate cancer (PCa) is a significant global health issue influenced by genetics, epigenetics, hormones, and environment.
- The human microbiome, particularly in the gut, urinary tract, and prostate, is increasingly recognized as a key factor in PCa initiation, progression, and treatment response.
Purpose of the Study:
- To explore the role of the gut-prostate microbial axis in PCa.
- To investigate how microbial dysbiosis impacts PCa development and therapeutic outcomes.
- To highlight the potential of microbiome-based interventions for PCa management.
Main Methods:
- Analysis of high-resolution multi-omics data from gut, urinary, and prostate microbial communities.
- Investigation of microbial metabolites and their impact on oncogenic pathways (e.g., IGF-1/MAPK/PI3K, NF-κB/JAK/STAT).
- Assessment of microbial influence on immune surveillance, hormonal metabolism, and epigenetic regulation.
Main Results:
- Microbial dysbiosis promotes chronic inflammation and modulates androgen receptor signaling in PCa.
- Specific bacteria like Akkermansia muciniphila can enhance anti-tumor immunity and improve response to androgen deprivation therapy.
- Microbiota-derived factors influence miRNA expression and epigenetic signatures, affecting tumor plasticity and therapy resistance.
Conclusions:
- The interconnectedness of the prostate, urinary, and gut microbiomes presents novel targets for PCa diagnostics and therapies.
- Microbiome-based strategies (probiotics, prebiotics, FMT, diet, bacteriophages) show promise for restoring balance and improving treatment efficacy.
- Further longitudinal studies integrating multi-omics and host-microbe interactomics are needed for clinical translation.
