New technique reveals earliest signs of genetic mutations

Mutations are changes in the molecular "letters" that make up the DNA code, the blueprint for all living cells. Some of these changes can have little effect, but others can lead to diseases, including cancer. Now, a new study ...

New insights on cellular clones and inflammation in bones

As humans age, hematopoietic stem cells—the immature precursor cells that give rise to all blood and immune cells—accumulate mutations. Some of the mutations allow these stem cells to self-renew and expand more effectively ...

Rare disease's mutation could explain more common conditions

TREX1 is a gene that is supposed to direct the maintenance of the entire body's DNA, but new research shows that when people are born with mutated TREX1, it causes catastrophic damage to the DNA over time, resulting in a ...
