Researchers in the US have discovered that the male hormone androgen may trigger the gene fusion that leads to the development of prostate cancer: they found that pieces of chromosome that normally sit far apart, relocate near each other after exposure to androgen, and this sets the scene for the genes to fuse.

Researchers have shown how an antiviral protein produced by the immune system, dubbed tetherin, tames HIV and other viruses by literally putting them on a leash, to prevent their escape from infected cells.

Researchers at the University of Michigan Comprehensive Cancer Center have discovered what leads to two genes fusing together, a phenomenon that has been shown to cause prostate cancer to develop. The study found that pieces of chromosome relocate near each other after exposure to the hormone androgen. This sets the scene for the gene fusion to occur. The finding is reported online Oct. 29 in Science Express.

The experiment, featured on the cover of the leading weekly science journal Cell of October 30, shows that cells use chance to survive uncertainty. “God does not play dice,” said Einstein to explain that chance does not intervene in nature.

New research has identified two genetic mutations that may put individuals at increased risk for fungal infections. The research focused on patients with severe fungal infections (primarily of the genus Candida), but the findings may also have implications for patients who have more common mild infections. The research is published in two studies that appear together in the October 29, 2009 issue of The New England Journal of Medicine.

Since the completion of the human genome sequence, a question has baffled researchers studying gene control: How is it that humans, being far more complex than the lowly yeast, do not proportionally contain in our genome significantly more gene-control proteins? Now, a collaborative eff
