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).

UAB researchers identify cell-surface marker that indicates fate of T cells

Follicular helper T cells, or Tfh cells, have a crucial role in immune defense. Without Tfh cells, B cells cannot form germinal center, or GC, responses during which high-affinity antibodies are generated.

New gene therapy shows promise for treating fusion-driven cancers

A new study presents a promising treatment method for so-called fusion-driven cancers, which are currently often difficult to cure. These fusion-driven cancers are caused by an error in cell division that creates a fusion of different genes.

Scientists develop "universal pan-mammalian clock" to accurately estimate age in mammals

Scientists at UCLA David Geffen School of Medicine and UCLA Health led an international research team that published two articles detailing changes in DNA – changes that researchers found are shared by humans and other mammals throughout history and are associated with life span and numerous other traits.
