Schizophrenia Not a Single Disease but Multiple Genetically Distinct Disorders

New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms. The finding could be a first step toward improved diagnosis and treatment for the debilitating psychiatric illness. The research at Washington University School of Medicine in St. Louis is reported online Sept. 15 in The American Journal of Psychiatry.

Muscular Dystrophy: Repair the Muscles, Not the Genetic Defect

A potential way to treat muscular dystrophy directly targets muscle repair instead of the underlying genetic defect that usually leads to the disease.

How an Ancient Vertebrate Uses Familiar Tools to Build a Strange-Looking Head

Investigator and Scientific Director Robb Krumlauf, Ph.D. and colleagues show that the sea lamprey Petromyzon marinus, a survivor of ancient jawless vertebrates, exhibits a pattern of gene expression that is reminiscent of its jawed cousins, who evolved much, much later.

Zebrafish Model of a Learning and Memory Disorder Shows Better Way to Target Treatment

Using a zebrafish model of a human genetic disease called neurofibromatosis, researchers have found that the learning and memory components of the disorder are distinct features that will likely need different treatment approaches.

Worldwide Study Demonstrates Accuracy of Genetic Analyses

Physicians envision a future in which genomic data from patients is heavily used to manage care — but experts have questioned the accuracy and reliability of these analyses. Now, a study by 150 researchers in 12 countries finds real strength and agreement across RNA genomic sequencing techniques and laboratories — as well as ways to improve what little variability exists to set a new high standard.

Genomic Analysis Reveals That a High-Risk Leukemia Subtype Becomes More Common with Age

More than one-quarter of young adults with the most common form of acute lymphoblastic leukemia (ALL) have a high-risk subtype with a poor prognosis and may benefit from drugs widely used to treat other types of leukemia that are more common in adults, according to multi-institutional research led by St. Jude Children’s Research Hospital investigators.

Penn Researcher and CVS Health Physician Urge New Payment Model for Costly Gene Therapy Treatments

Hoping to encourage sufficient investments by pharmaceutical companies in expensive gene therapies, which often consist of a single treatment, a Penn researcher and the chief medical officer of CVS Health outline an alternative payment model.

Bacteria Harbor Secret Weapons Against Antibiotics

BMF-Austin-Photo-GelCompetition.jpg

The ability of pathogenic bacteria to evolve resistance to antibiotic drugs poses a growing threat to human health worldwide, and scientists have now discovered that some of our microscopic enemies may be even craftier than we suspected, using hidden genetic changes to promote rapid evolution under stress and developing antibiotic resistance in more ways than previously thought. The results appear in a new paper in the journal Biomicrofluidics.
