National Institute on Aging (NIA) researchers have discovered a new gene, FANCM, which sheds light on an important pathway involved in the repair of damaged DNA. Specifically, mutation in this gene is responsible for one of the forms of Fanconi anemia (FA), a rare genetic disorder that primarily affects children. Like many rare, inherited diseases, understanding this gene’s role in the development of FA provides insights into other medical problems -- in this case, age-related conditions including ovarian and pancreatic cancers, as well as leukemia, the researchers said. Discovery of this gene and its protein provides a potential target for the development of drugs that can prevent or alleviate FA and a variety of cancers.
The finding is scheduled for advanced online publication in Nature Genetics during the week of August 21, 2005.* The report also will be published in the journal’s September 2005 print edition. The NIA is a component of the National Institutes of Health (NIH) at the U.S. Department of Health and Human Services.
"FA is a disease that appears to be the result of a breakdown in vital DNA repair mechanisms," said Weidong Wang, Ph.D., a senior investigator in the NIA’s Laboratory of Genetics, who led the study. "Some scientists theorize that DNA damage, which gradually accumulates as we age, leads to malfunctioning genes and deteriorating tissues and organs as well as increased risk of cancer. We believe that this new gene, FANCM, may be a potent cog in the DNA repair machinery," Wang said. "It is possible that we could learn how to promote the function of DNA repair complexes and thereby prevent the age-related accumulation of DNA damage."

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...
