Genes Discovered That Allow Gum Disease Bacterium To Invade Arteries
Published on 2009-11-27 23:48:00
Researchers have identified the genes in gum-disease bacteria that allow them to invade and infect human arterial cells, offering one possible explanation for a perceived connection between gum disease and heart disease. Scientists from the University of Florida, Gainesville, present their findings today at the 106th General Meeting of the American Society for Microbiology in Orlando, Florida."Aside from lifestyle and genetic factors, there is increasing evidence that bacterial infections may pl

Knockouts in Human Cells Point to Pathogenic Targetsresearchers have developed a new type of genetic screen for human cells to pinpoint specific genes and proteins used by pathogens, according to their paper in Science.In most human cell cultures genes are present in two copies: one inherited from the father and one from the mother. Gene inactivation by mutation is therefore inefficient because when one copy is inactivated, the second copy usually remains active and takes over.In yeast, research
