Biologists have developed an efficient way to genetically modify human embryonic stem cells. Their approach, which uses bacterial artificial chromosomes to swap in defective copies of genes, will make possible the rapid development of stem cell lines that can both serve as models for human genetic diseases and as testbeds on which to screen potential [...]

A new study in the January issue of the Journal of Vascular Surgery(®), published by the Society for Vascular Surgery®, reveals robust epidemiological evidence that hereditary factors contribute to aneurysm formation in twins.

It’s the ultimate goal in the treatment of cancer: tailoring a person’s therapy based on his or her genetic makeup. While a lofty goal, scientists are steadily moving forward, rapidly exploiting new technologies. Researchers at Georgetown Lombardi Comprehensive Cancer Center report a significant advance in this field of research using a new chip that looks [...]

Identical twins look the same and are nearly genetically identical, but environmental factors and the resulting cellular changes could cause disease in one sibling and not the other. In a study published online in Genome Research (www.genome.org), scientists have studied twins discordant for the autoimmune disease lupus, mapping DNA modifications across the genome and shedding [...]

The results of a new study on immune-based treatment of Alzheimer’s disease (AD), which was conducted at 30 sites around the country, will be published in the December 15 issue of Neurology®. Lead author, Stephen P. Salloway, MD, MS, director of the Butler Hospital Memory and Aging Program and a professor of neurology and psychiatry [...]
