Gold nanoparticles improve gene regulation

Investigators at Northwestern University have found that packing small interfering RNA (siRNA) molecules onto the surface of a gold nanoparticle can protect siRNAs from degradation and increase their ability to regulate genes involved in cancer. As a result of this discovery, cancer researchers have at their disposal a relatively straightforward method of delivering these potent gene-regulating agents into targeted cells.

Epigenetics may account for some inherited traits and diseases

Embargoed Until January 18, 2009 at 18:00 Greenwich Mean Time / 13:00 Eastern Standard Time (TORONTO): Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases.

Discovery of first gender-linked susceptibility gene for late-onset Alzheimer's disease

In the Jan. 11 online edition of Nature Genetics, they report the results of their two-stage genome-wide association study of patients with Alzheimer's disease. The research showed that women who inherited two copies of a variant in the PCDH11X gene, found on the X chromosome, are at considerably greater risk of developing Alzheimer's disease.
