Epigenetics in Toxicology Sep. 17 2024

Points

  1. Epigenetic processes regulate cell differentiation and function by defining long-term accessibility and thus inducibility of genes
  2. Main epigenetic mechanisms are DNA methylation, histone modifications/variations, chromatin structure, and non-coding RNAs
  3. Epigenetic patterns are sensitive to environmental factors
  4. Epigenetic changes would be useful early markers for adverse outcomes induced by exposure once clear links between exposure, epigenetic changes, and adverse outcomes are established.
  5. Epigenetic changes induced by the environment can be tranferred to next, unexposed generations, a phenomenon called transgenerational epigenetic inheritance
