Hate Exercise? It May Be in Your Genes

Genes, specifically those that modulate dopamine in the brain, may play a role in a person’s propensity to embrace or avoid exercise. Rodney Dishman of the University of Georgia will present findings from studies in rats and humans in his talk “Genetics of Exercise Avoidance” at the Integrative Biology of Exercise 7 meeting in Phoenix.

New TSRI Study Suggests Ebola Can Adapt to Better Target Human Cells

20161103Andersen_Grubaugh.jpg

A new study co-led by scientists at The Scripps Research Institute (TSRI) suggests that Ebola virus gained a genetic mutation during the 2013–16 epidemic that appears to have helped it better target human cells.

Studies Reveal WSU-Conceived Non-Invasive Prenatal Genetic Test Is Accurate Five Weeks Into Pregnancy

The latest developments in prenatal technology conceived by scientists at the Wayne State University School of Medicine that make it possible to test for genetic disorders a little more than one month into pregnancy were revealed this week in Science Translational Medicine, a journal of the American Association for the Advancement of Science.

Major Family of Gene-Regulating Proteins Has Drug-Sized Pocket

NPASstructure.jpg

An entire class of proteins called transcription factors has largely been ignored by the pharmaceutical industry because it’s difficult to design and screen drugs against them. But a new study from scientists at Sanford Burnham Prebys Medical Discovery Institute suggests that a key group of transcription factors are in fact ‘druggable,’ including several that could be targeted to treat cancer, metabolic disease, or autoimmune conditions. The paper, published in eLIFE, shows that at least seven bHLH-PAS proteins have pockets where drugs would fit and remain tightly bound.

Researchers ID First Two Genes Regulating Sleep in Mice Using Genetic Screening

Researchers have identified the first two core genes that regulate the amount of deep sleep and dreaming, a key development they believe will lead to the discovery of a network of related genes controlling sleep.

New Book Looks at Postwar History of Genetic Disease

Many think of eugenics as a scientific and social movement of the past, which quickly fell out of favor after World War II. In recent decades, however, the specter of eugenics has been making something of a comeback as tests for genetic disorders have become more readily available to expecting parents.

A Lot of Blood, for No Reason? U-M Team Concludes That Common, Costly Clot Test Has Few Benefits

bloodvialsstock.jpg

A half billion dollars – at least -- gets spent each year on blood tests to see which hospital patients have a genetic quirk that makes their blood more likely to form dangerous clots. And most of that spending probably isn’t necessary, a new review shows.

Single Mutation in Recessive Gene Increases Risk of Earlier Onset Parkinson’s Disease

A collaboration of 32 researchers in seven countries, led by scientists at Mayo Clinic’s campus in Florida, has found a genetic mutation they say confers a risk for development of Parkinson’s disease earlier than usual.

Yeast Holds the Key to Humans’ Genetic Response to Stress, Herbicide Exposure

Yeast’s ability to grow, divide, age and metabolize food is similar to human cells and provides researchers with a nearly perfect specimen to study cell processes and genetic variation. Biologist Jennifer Gallagher is taking advantage of the organism’s functions to examine how an individual would respond to stress at a molecular level, and the effects herbicides such as the common household weedkiller RoundUp, have on genes.

LJI Scientists Flip Molecular Switches to Distinguish Closely Related Immune Cell Populations

The cornerstone of genetics is the loss-of-function experiment. In short, this means that to figure out what exactly gene X is doing in a tissue of interest—be it developing brain cells or a pancreatic tumor—you somehow cut out, switch off or otherwise destroy gene X in that tissue and then watch what happens. That genetic litmus test has been applied since before people even knew the chemical DNA is what makes up genes. What has changed radically are the tools used by biologists to inactivate a gene.

New Study ‘Sheds Light’ on the Mechanisms Safeguarding the Genome

Understanding the molecular mechanisms that exist for cells to safeguard their genome against cancer-causing defects is crucial not only to understand how cancer arises but also because these mechanisms can be targeted therapeutically. Researchers have identified a new net of molecular interactions occurring within cells upon exposure to DNA damaging UV radiation. The team lead by Antonio Giordano, MD, PhD, Director and Founder of the Sbarro Health Research Organization at Philadelphia, PA , published their findings in Oncotarget.

UC San Diego School of Medicine Researchers Receive $5 Million in Type 1 Diabetes Grants

There are many unanswered questions about the mechanisms that contribute to the onset of type 1 diabetes. Researchers at University of California San Diego School of Medicine hope to answer some of them with two Type 1 Diabetes Special Statutory Funding Program grants from the National Institutes of Health totaling more than $5 million.
