Understanding Epigenetics and Its Role in Cell Identity, Disease, and Drug Resistance

This chapter covers the concept of epigenetics and its regulation of gene expression through chemical modifications, emphasizing its importance in cell identity maintenance and disease development like cancer. It explores how cells can modify their epigenetic profiles naturally or pathologically, touching on the significance of epigenetic marks in predicting cell behavior, especially in cancer contexts. The chapter also addresses misconceptions related to interactions between medications like vitamin K2 and Eliquis, as well as lifestyle factors like nightly beer consumption and its impact on liver cancer risk.
