The Gut Microbiome and Epigenomic Reprogramming: Mechanisms, Interactions, and Implications for Human Health and...

Area of Science:

• Microbiology
• Epigenetics
• Host-Microbe Interactions

Background:

• The human gut microbiome is a complex ecosystem impacting host physiology via epigenetic modifications like DNA and RNA methylation.
• Environmental factors and microbial metabolites shape these epigenetic changes, but molecular pathways are not fully understood.

Purpose of the Study:

• To review recent advances in understanding how the gut microbiome interacts with and modulates host epigenome.
• To explore conserved molecular pathways and host factors involved in microbiome-epigenome communication.
• To outline translational applications for microbiome-informed health strategies.

Main Methods:

• Literature review of mechanistic discoveries and conceptual advances.
• Discussion of evolutionarily conserved pathways (e.g., one-carbon metabolism, SCFAs, EVs).
• Examination of host factors (diet, aging, immunity) and technological advancements (AI, multi-omics).

Main Results:

• Identified conserved pathways through which gut microbiota regulate host methylation.
• Highlighted reciprocal influences between host factors and microbial communities.
• Outlined translational frontiers including biomarker discovery and novel therapeutics.

Conclusions:

• Microbiome-epigenome interactions are crucial for host physiology and plasticity.
• Further research into these complex interactions can drive precision health and disease prevention.
• Standardization and ethical data governance are essential for clinical translation.
