Gene therapy - Aim to improve blood flow

...alifornia in San Francisco, found a way to produce mice whose skin cells had high levels of activity of a gene called HIF-1. Researchers have managed to produce a genetically-altered mouse which has grown large numbers of new blood capillaries in its skin. This gene is known to send commands to several ...

UV Radiation induces Melanoma

A single dose of UV radiation was enough to induce melanoma in the young mice. In adults, 30 times more UV was needed to achieve the same effect. Glenn Merlino, chie...
