Cancer drugs that work in mice have about an eight percent success rate in humans.5“We focus on other organisms(生物体) as well as mice, but mice are the best organism for us to use. "And whatever your qualms(良心不安) about animal rights, testing on mice is better than doing ...
The author reflects on the treatment of duchenne muscular dystrophy (DMD), a genetic disease causing premature death in young adults, with RNA modulation using antisense oligonucleotides (AONs). He says that treatment corrects the out-of-frame genetic disorder through exon skipping. He mentions the...
