One of the earliest events that changes a normal cell into a malignant one is known as deoxyribonucleic acid (DNA) hypermethylation, a biochemical alteration that inactivates critical tumor-suppressor genes. A team of investigators at Johns Hopkins University has developed a quantum dot-based method that can quantify DNA methylation in premalignant cells harvested from human patients.
