By | May 19, 2008

Scientists have created the first transgenic monkey model of Huntington disease (HD), according to a linkurl:report;http://www.nature.com/nature/journal/vaop/ncurrent/abs/nature06975.html that appeared yesterday in Nature. But it's unclear how closely the model represents the disease in humans.

Mutant p53 thwarts cancer therapy

By | May 14, 2008

Some potential cancer therapies may do more harm than good: A class of compounds intended to boost tumor suppressor p53 activity may actually promote mutant versions of the gene, a linkurl:study;http://www.genesdev.org/cgi/content/abstract/22/10/1337 published tomorrow in Genes and Development reports. p53, the tumor suppressor found in roughly half of all human cancers, works by signaling cell death, thus keeping cell growth in check.
