Fox Chase Cancer Center scientists identify immune-system mutation

...r-deficient mice his team discovered represent the second time that a naturally occurring mutant strain has been found and bred at Fox Chase.

In the second study, just like in the first study, mice were treated with hormones but, before being exposed to the real herpes virus, they received a vaccine Surprisingly, unlike in the first study, the progesterone-treated mice and the mice that received no hor...

Gene variations explain drug dose required to control seizures

... patients with epilepsy. Moreover, a variant of a second gene, called SCN1A, with activity in the brain, was found significantly more often in patients on the highest doses of both carbamazepine and phenytoin. SCN1A has been implicated in many inherited forms of epilepsy and is the drug target for phenytoi...

Muscle-targeted gene therapy reverses rare muscular dystrophy in mice
