A collaboration of scientists mainly from the Fred Hutchinson Cancer Center and at the University of Washington (Seattle) has made an important discovery linking the powerful cancer-causing oncogene, myc, with the gene behind the premature aging disease, Werner syndrome. Their finding reveals that the MYC oncoprotein turns-on Werner syndrome gene expression, and posits the Werner syndrome gene as a potentially important participant in MYC-induced tumorigenesis.
Werner syndrome is a rare genetic disorder characterized by the appearance of old age beginning after puberty. It is caused by mutations in the Werner syndrome gene (WRN), which resides on the short arm of human chromosome 8. The WRN gene encodes a DNA helicase (an enzyme that unwinds DNA) involved in DNA replication and repair.
As published in the July 1 issue of Genes & Development, Dr. Carla Grandori and colleagues have discovered that WRN expression is regulated by the MYC oncoprotein, which is implicated in about one third of all human cancers.

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.
To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...
The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.
Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
