Promising gene therapy could restore vision in humans

It was surprisingly simple. University of California, Berkeley, scientists inserted a gene for a green-light receptor into the eyes of blind mice and, a month later, they were navigating around obstacles as easily as mice with no vision problems.

			First gene therapy operation for macular degeneration is a success A new treatment is the first to target the underlying genetic cause of AMD, which affects more than 600,000 people in the UK alone.

			Researchers discover how cancer cells avoid genetic meltdown A team of scientists have shed light on how cancer cell populations avoid genetic meltdown, despite the rapid accumulation of harmful mutations.

	Geneticists discover how sex-linked disorders arise Researchers at the University of Melbourne have made an important discovery that explains why some babies are born with disorders of sex development. The study suggests that a critical regulatory gene carried on the Y chromosome increases or decreases the activity of particular gene that determine whether a baby will be male or female.

	Understanding genetic interactions holds key to new personalized therapies When the Human Genome Project was completed, in 2003, it opened the door to a radical new idea of health - that of personalized medicine, in which disease risk and appropriate treatment would be gleaned from one's genetic makeup.

	Study illuminates how hot spots of genetic variation evolved in the human genome What makes one person different from one another, and how did these differences evolve? A study by University at Buffalo biologists is illuminating one aspect of this complicated question. The research examines hot spots of genetic variation within the human genome, examining the sections of our DNA that are most likely to differ significantly from one person to another.

	Scientists identify common genetic variants associated with post-stroke recovery Our genes may have a bearing not only on our stroke risk, but probably also on how well we recover after stroke. For the first time, in international collaboration, scientists at the University of Gothenburg and elsewhere have identified common genetic variants that are associated with outcome after ischemic stroke.

	Current HBV genome sequences help deduce ancient human population movements into Australia Australian researchers have used current hepatitis B virus (HBV) genome sequences to deduce ancient human population movements into Australia, adding weight to the theory that the mainland Aboriginal population separated from other early humans at least 59 thousand years ago and possibly entered the country near the Tiwi Islands.
