DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

p53 mutations show diverse impact on pancreatic cancer metabolism

A research team at the University of Konstanz, led by toxicologist Ivano Amelio, has demonstrated how differently individual mutations of the tumor suppressor p53 affect pancreatic carcinomas.
