Scientists at Fox Chase Cancer Center have released a comprehensive review paper that chronicles the history of DNA amplification research. The paper, which is featured on the cover of a special issue of the Journal of Biological Chemistry, offers insights into decades of discoveries and outlines potential future directions in this field.
DNA amplification is a natural process that increases the number of copies of certain DNA sequences. This process has significant implications for cancer and other diseases, as cancer cells often exploit it to enhance the expression of oncogenes, thereby promoting tumor growth and survival. Historically viewed as random, recent studies have shown that DNA amplification is controlled by regulatory networks.
“The goal of the review is to provide historical perspective to demonstrate that amplifications are not necessarily a pathological consequence, but that there are regulatory networks that control them,” said , Director of the and Co-Leader of the at Fox Chase, who also served as the corresponding author on this review.
Chloe Azadegan from Drexel University was the first author on this study. She recently received an Epigenetics Summer Course Fellowship through a collaboration between CEI and Institute Curie in Paris.
The review honors C. David Allis, PhD, a renowned epigenetics researcher who contributed significantly to understanding how epigenetic factors regulate DNA amplification. Whetstine highlighted Allis’s role in his early work demonstrating epigenetic regulation’s impact on DNA amplification.
Whetstine’s lab aims to shed light on how understanding DNA amplification can aid in identifying biomarkers or therapeutic targets for diseases linked with this process, such as cancer. He emphasized ongoing interest in using this knowledge for therapeutic interventions.
Reflecting on advancements in this field, Whetstine remarked: “After all these years, if someone asked me what I thought the most important thing about DNA amplification research was, I would say this: Dogma doesn’t matter, and don’t assume that what you see is the final state,” adding that “the genome is far more plastic than I ever thought it would be.”
