Mount Sinai Researchers Discover Gut Bacteria's Epigenetic Adaptation Strategy
Researchers at the Icahn School of Medicine at Mount Sinai have identified a novel survival strategy used by gut bacteria, termed epigenetic 'bet-hedging'. This mechanism allows bacteria to adapt to environmental changes, such as antibiotic exposure 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 through DNA methylation, which regulates gene expression and enhances bacterial resilience. This discovery sheds light on the adaptive capacity of the gut microbiome, which is crucial for understanding its dynamic relationship with human health and disease.
