Reactivated Gene Sets Immune System Back 500M Years

August 19, 2014 11:37 am | News | Comments

A single factor can reset the immune system of mice to a state likely similar to what it was 500 million years ago. Scientists reactivated expression of an ancient gene in mice, which is not normally expressed in the mammalian immune system, and found that the animals developed a fish-like thymus.

August 15, 2014 12:14 pm | News | Comments

Links between a number of common respiratory diseases and an increased risk of developing lung cancer have been found in a large pooled analysis of seven studies involving more than 25,000 individuals.               

Early Antibiotic Exposure Gives Mice Lifelong Metabolic Issues

August 15, 2014 11:59 am | News | Comments

A new study suggests that antibiotic exposure during a critical window of early development disrupts the bacterial landscape of the gut, home to trillions of diverse microbes, and permanently reprograms the body’s metabolism, setting up a predisposition to obesity.

New Gene Editing Method Shows Promising Results for Correcting Muscular Dystrophy

August 15, 2014 11:30 am | News | Comments

UT Southwestern Medical Center researchers successfully used a new gene editing method to correct a mutation that leads to Duchenne muscular dystrophy (DMD) in a mouse model of the condition. Researchers used a technique called CRISPR/Cas9-mediated genome editing, which can precisely remove a mutation in DNA, allowing the body’s DNA repair mechanisms to replace it with a normal copy of the gene.
