A Cedars-Sinai study has identified a previously unknown role for astrocyte cells in how the brain responds to damage and ...

Researchers have discovered how cells activate a last-resort DNA repair system when severe damage strikes. When genetic ...

Genome instability can cause numerous diseases. Cells have effective DNA repair mechanisms at their disposal. A research team has now gained new insights into the DNA damage response. Whenever cells ...

A previously unknown type of DNA damage in the mitochondria, the tiny power plants inside our cells, could shed light on how our bodies sense and respond to stress. The findings of the UC ...

For patients with severe corneal injuries, blindness has often been seen as a life sentence. But a new eye stem cell transplant may change that. Scientists at Massachusetts Eye and Ear have ...

Ultraviolet (UV) radiation is known to cause DNA damage, and while that damage may accumulate and eventually lead to diseases like skin cancer, cells also have repair mechanisms that can fix ...

When we developed the ability to convert various cells into a stem cell, it held the promise of an entirely new type of therapy. Rather than getting the body to try to fix itself with its cells or ...

Whenever cells divide, there is a high risk of damage to the genetic material. After all, the cell has to duplicate its entire genetic material and copy billions of genetic letters before it divides.
