Johns Hopkins Medicine scientists say they have found a pattern of so-called epigenetic “marks” in a transition state between normal and pancreatic cancer cells in mice, and that the normal cells may keep at least a temporary “memory” of those cancer-linked marks.
Epigenetic marks are chemical modifications that help regulate genetic expression without directly altering DNA sequence in the makeup of genes. While the genetic code is like a computer’s hardware, epigenetics involves chemical…
