Discovery may open door for treating fragile X carriers

Fragile X syndrome, an inherited cause of autism and intellectual disability, can have consequences even for carriers of the disorder who don’t have full-blown symptoms. Researchers at Washington University School of Medicine in St. Louis have identified a potential target for treatment for fragile X carriers.

DNA sequencing helps identify cancer cells for immune system attack

DNA sequences from tumor cells can be used to direct the immune system to attack cancer, according to Robert Schreiber, PhD, the Alumni Professor of Pathology and Immunology at Washington University School of Medicine in St. Louis. The research, in mice, appears online Feb. 8 in Nature.

Researchers discover pathway to cell size, division

Researchers at Washington University in St. Louis have discovered through genetic analyses a metabolic pathway in bacteria comprised of just three genes, all known to be players in metabolism. This pathway was previously shown to be involved in synthesizing modified membrane lipids but data from Petra Levin’s lab indicate that it also has a major role in cell division. This is the first identification of a pathway responsible for regulating bacterial cell size.
