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 ...

Cancer can be caused by reversible molecular changes, study shows

Though 1 in 2 people will develop some form of cancer in their lifetime, there's still much we don't know about this disease. But thanks to continued research efforts, we keep learning more about the biology of cancer. One ...

Engineered DNA 'warhead' targets a common cancer mutation

Tumor protein P53 (TP53) plays an important role in suppressing the growth of tumors. Mutations in the gene for TP53 can have a disastrous effect, hampering the body's ability to fight tumors and even encouraging their growth. ...
