Faulty Bioelectric Signal Responsible for Facial Defects Caused by Rare Genetic Disorder

JPhysAdams_Levin_2.3.16.jpg

Faulty bioelectric signaling has been found to be responsible for the skull and facial abnormalities that characterize the rare genetic disorder Andersen-Tawil Syndrome (ATS). It may therefore be possible to alter bioelectrical signaling to correct effects of fetal alcohol syndrome and other developmental defects or genetic mutations.

A Child’s Cardiac Arrest Should Prompt Check-Ups for the Rest of the Family

HeartMonitor.jpeg

With fewer than 3,500 episodes a year, cardiac arrest in children is decidedly rare, but it could be a dramatic signal that the victim’s family members may be at a heightened risk for sudden cardiac death. This is why, in the aftermath of such a traumatic event, clinical evaluation of the child’s parents and siblings could lead to lifesaving diagnoses and therapies, averting further tragedy, say cardiologists at Ann & Robert H. Lurie Children’s Hospital of Chicago

Scientists Elucidate Genetic Underpinnings of Congenital Heart Disease

Mutations in the gene TBX5 have been shown to cause both rare and more prevalent forms of congenital heart disease, yet the underlying mechanisms have remained unclear. A team led by researchers at the University of North Carolina at Chapel Hill has now found evidence pointing to a culprit.

Chromosomes Reconfigure as Cell Division Ends

107938_web.jpg

Cellular senescence -- when a cell can no longer divide -- is a programmed stage in a cell's life cycle. Sometimes, as in aging, we wish it didn't happen so much and sometimes, as in cancer, we wish it would happen more. Given its important impacts on health, biologists wish they could explain more about what's happening in cells when senescence takes hold. A new study helps by showing that chromosomes become somewhat transformed, altering their patterns of gene expression.

Penn Medicine and LouLou Foundation Create Program of Excellence for Rare Genetic Disorder That Affects Children

The London-based LouLou Foundation and the Orphan Disease Center of the Perelman School of Medicine at the University of Pennsylvania have established a Program of Excellence to develop effective treatments for children with CDKL5, a rare X-chromosome-linked genetic disorder that causes severe neuro-developmental impairment and early-onset, difficult-to-control seizures.

The Evolution of Dark-Fly

dark-fly.gif

On November 11, 1954, Syuiti Mori turned out the lights on a small group of fruit flies. More than sixty years later, the descendents of those flies have adapted to life without light. These flies—a variety now known as “Dark-fly”—outcompete their light-loving cousins when they live together in constant darkness, according to research reported in the February issue of G3: Genes|Genomes|Genetics. This competitive difference allowed the researchers to re-play the evolution of Dark-fly and identify the genomic regions that contribute to its success in the dark.

Delivering Genes Across the Blood-Brain Barrier

AAV9-vs-PHP_B-figure-RV-NEWS-WEB.jpg

Caltech biologists have modified a harmless virus in such a way that it can successfully enter the adult mouse brain through the bloodstream and deliver genes to cells of the nervous system. The virus could help researchers map the intricacies of the brain and holds promise for the delivery of novel therapeutics to address diseases such as Alzheimer's and Huntington's. In addition, the screening approach the researchers developed to identify the virus could be used to make additional vectors capable of targeting cells in other organs.

Cotton's genetic history is full of surprises. From transoceanic travels to inter-species cross-breedings, cotton’s story is one of plant and seed survival, adaptation, and human cultivation. What started as a naturally tough, unspinnable fiber has been transformed into something most folks adore for its soft, comforting feel.

Seafood Consumption May Play a Role in Reducing Risk for Alzheimer’s

New research published Feb. 2 in the Journal of the American Medical Association found that older adults with a major risk gene for Alzheimer’s disease known as APOEɛ4 who ate at least one seafood serving per week showed fewer signs of Alzheimer’s-related brain changes. In contrast, this association was not found in the brains of volunteers who ate fish weekly but did not carry the risk gene.
