New gene therapy for vision loss proven safe in humans

Researchers have shown that an experimental gene therapy is safe and may be effective in preserving vision in people with wet age-related macular degeneration. The treatment involves injecting a virus containing a therapeutic gene into the eye, which produces a protein to prevent abnormal blood vessel growth.

Some mother cells kick DNA damage 'down the road' to offspring, CU study says

A CU Boulder study shows that some dividing human cells transmit low-level DNA damage to their daughters, causing them to enter a quiescent state previously thought to be random. The process is linked to the fate of daughter cells in subsequent cell cycles and has implications for cancer development and aging.
