Explain the relevance of epigenetics on disease development and treatment
● Environmental factors (eg. diet, stress, toxins) can lead to epigenetic changes
● These can stimulate / inhibit expression of certain genes that can lead to disease development
○ Increased methylation of DNA OR decreased acetylation of histones inhibits transcription
○ Decreased methylation of DNA OR increased acetylation of histones stimulates transcription
● Diagnostic tests can be developed that detect these epigenetic changes before symptoms present
● Drugs can be developed to reverse these epigenetic changes
