Critical step found in DNA repair, cellular aging. A Cure for Ageing? | QPT


DNA repair is essential for cell vitality,
cell survival, and cancer prevention, yet cells’ ability to patch up damaged DNA declines
with age for reasons not fully understood. Now, research led by scientists at Harvard
Medical School (HMS) reveals a critical step in a molecular chain of events that allows
cells to mend their broken DNA. Their Experiments in mice suggest way to prevent DNA damage from aging and radiation.
