Latest Gene Stories
In the cover story for the journal Genetics this month, neurobiologist Dan Chase and colleagues at the University of Massachusetts Amherst describe a new experimental technique they developed that will allow scientists to study the function of individual proteins in individual cell types in a living organism.
GB HealthWatch has just released an innovative
Individuals of a particular species generally differ from one another.
The study reveals how a genetic duplication that occurred millions of years ago encouraged the evolution of the ASF1b gene, involved in cancer development
Using a novel genetic 'editing' technique, Duke University biomedical engineers have been able to repair a defect responsible for one of the most common inherited disorders, Duchenne muscular dystrophy, in cell samples from Duchenne patients.
Albert Erives, associate professor in the University of Iowa Department of Biology, and his graduate student, Justin Crocker, currently a postdoctoral researcher at the Howard Hughes Medical Institute (HHMI) Janelia Farm Research Campus, have conducted a study that reveals important and useful insights into how and why developmental genes often take inputs from two independent “morphogen concentration gradients.”
These days, phylogeneticists – experts who painstakingly map the complex branches of the tree of life – suffer from an embarrassment of riches. The genomics revolution has given them mountains of DNA data that they can sift through to reconstruct the evolutionary history that connects all living beings.
Researchers have found that a unique little carnivorous plant is particularly interesting for geneticists because it does not appear to have so-called 'junk' DNA – 97 percent of its genome is comprised of actual genes.
A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...
