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).

FDA-approved anti-sedative could alleviate common side effects of cancer treatments

Cell's anti-aging structures can set the damage threshold a cancer cell can sustain, study shows

A new study led by Claus M. Azzalin, group leader at Instituto de Medicina Molecular João Lobo Antunes- iMM and published today in the prestigious scientific journal Proceedings of the National Academy of Sciences (PNAS) shows, for the first time, that the cell's anti-aging structures – the telomeres – can set the damage threshold a cancer cell can sustain and above which cells cannot continue to divide and die.
