Icahn School of Medicine Researchers Discover Gut Bacteria's Epigenetic Adaptation Strategy
Researchers at the Icahn School of Medicine at Mount Sinai have uncovered a novel survival strategy used by gut bacteria, termed epigenetic 'bet-hedging'. This mechanism allows bacteria to adapt to environmental changes such as antibiotics and dietary shifts without relying solely on genetic mutations. The study, published in Cell Host & Microbe, reveals that gut microbes can switch between functional states, enhancing their resilience. This discovery sheds light on the adaptive capacity of the gut microbiome, which is crucial for understanding its dynamic relationship with human health. The research highlights the role of DNA methylation in regulating gene expression and facilitating epigenetic phase variation, a process previously observed in pathogenic bacteria but now identified in beneficial gut microbes.
