Genetic Variation Determines Protein’s Response to Anti-Diabetic Drug

LazarSoccioGraphicalAbstractCellJuly15.jpg

In the first study of its kind, researchers have shown how an anti-diabetic drug can have variable effects depending on small natural differences in DNA sequence between individuals. They aim to apply this knowledge to develop personalized approaches to treating diabetes and other metabolic disorders.

Genetic Testing in Kids is Fraught with Complications

Despite an increasing ease in acquiring genetic information, the American Society of Human Genetics (ASHG) points out that doing so has consequences, particularly when it comes to children. It is this population, they say, that is the most vulnerable. With this precaution in mind, the ASHG Workgroup on Pediatric Genetic and Genomic Testing has issued guidelines for genetic testing in children and adolescents that are based on a thorough review of studies on ethical, legal, and social implications (ELSI). The recommendations were published in The American Journal of Human Genetics.

First Comprehensive Analysis of the Woolly Mammoth Genome Completed

The first comprehensive analysis of the woolly mammoth genome reveals extensive genetic changes that allowed mammoths to adapt arctic life, including skin and hair development, insulin signaling, fat biology, and even traits such as small ears and short tails. A mammoth gene for temperature sensation was resurrected in the lab as a functional test.

With New Spotlight on Batten Disease – Can Gene Therapy Provide an Answer?

According to Dr. Tammy Kielian, there are no treatments available that can halt or reverse the symptoms of children with juvenile Batten disease, but earlier studies using AAV gene therapy at UNMC have demonstrated significant and promising results in animal models of the disease.
