Healing power in a gene
...with liver cells lacking the FoxM1B gene. Rates of regeneration
were measured in these mice and in mice whose FoxM1B gene was intact. Without FoxM1B, regeneration
was slow. Cell division requires two basic steps: first a doubling of DNA, the genetic instructions ...

Mighty mice are less susceptible to muscular dystrophy gene's effects
...scientists hope to unravel the mechanism of muscle regeneration
in mice with and without myostatin, possibly revealing even better targets for improving the process. They also plan to use special genetic manipulations to turn off the myostatin gene in adult mice, rather than at conception, to see if losing myosta...

Your brain is teaching your nose new tricks, say UC Berkeley researchers
...activity in damaged regions of the body results in regeneration
in the brain. For example, in stroke patients, tying down the unaffected limbs to force patients to try use their affected arms or legs has resulted in recovery of some use of those limbs. The researchers conducted their work through a very simple m...
