A research team led by The University of Texas M. D. Anderson Cancer Center has found a potential new protein marker for prognosis of breast and ovarian cancer.
In the November, 2004 issue of the journal Nature Medicine, the researchers report tumor cells that "overexpress" the protein Rab25 are more aggressive and associated with poorer outcome. Thus, Rab25 could represent a novel therapeutic target or marker of tumor behavior, they say.
The researchers matched tumor samples to outcomes in about 100 patients diagnosed with either breast or ovarian cancer and found that a low level of Rab25 protein on a patients cancer sample was associated with a better clinical outcome in both cancer types. For example, patients with early stage (I and II) ovarian cancer who had low Rab25 tumor expression had an 80 percent survival five years after treatment, compared to 50 percent survival if Rab25 expression was high. In women with advanced breast cancer, a low level of Rab25 protein expression was associated with a 60 percent five-year survival, compared to 40 percent if Rab25 protein expression was high.

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...
