Epigenetic modulating compounds as potential therapeutic agents for oesophageal cancer management

Roisin Cassidy

Despite recent advances in treatment strategies for oesophageal cancer. there has been no significant improvement in overall survival ratefor advanced diseases. Thus, new strategies are necessary to improve treatment options for patients with oesophageal cancer. Epigenetics is a relatively new field of molecular biology. It is a complex mechanism of gene regulation, defined as the collection of heritable changes in DNA that affect the packaging of chromatin. Epigenetic changes are different from mutations that change the underlying structure of DNA and have a normal and vital process in cell differentiation and development Roisin Cassidy.

In general, however, cancer (including oesophageal cancer) is a disease of widespread epigenetic dysregulation that interacts extensively with underlying genetic mutations. Changes in DNA methylation patterns are known to be key drivers of oesophageal carcinogenesis.
