Scientists create animal models by altering specific genes associated with a given disease

Whitehead Institute Founding Member Rudolf Jaenisch, who helped transform the study of genetics by creating the first transgenic mouse in 1974, is again revolutionizing how genetically altered animal models are created and perhaps even redefining what species may serve as models.

Fralin Life Science Institute researchers use TALENS to alter mosquito genome

Virginia Tech researchers successfully used a gene disruption technique to change the eye color of a mosquito - a critical step toward new genetic strategies aimed at disrupting the transmission of diseases such as dengue fever.

Tau release from healthy neurons can be regulated by neuronal activity

Researchers from King's College London have discovered that neuronal activity can stimulate tau release from healthy neurons in the absence of cell death.

Scientists demonstrate how glowing fish can help screen drugs that control metabolic disorders

A tiny, translucent zebrafish that glows green when its liver makes glucose has helped an international team of researchers identify a compound that regulates whole-body metabolism and appears to protect obese mice from signs of metabolic disorders.

DFG to establish 11 Collaborative Research Centres in Jan 2013

The Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) will establish eleven Collaborative Research Centres (CRCs) as of 1 January 2013. This was decided by the responsible Grants Committee during its fall session in Bonn.

UiO researchers discover enzyme critical for spread of cancer

Enzyme hunters at UiO have discovered the function of an enzyme that is important in the spreading of cancer. Cancer researchers now hope to inhibit the enzyme.

Oskar gene emerged far earlier in insect evolution than previously believed

Harvard scientists have solved the long-standing mystery of how some insects form the germ cells - the cellular precursors to the eggs and sperm necessary for sexual reproduction - and the answer is shedding new light on the evolutionary origins of a gene that had long been thought to be critical to the process.

Two CUMC studies provide new insights into spinal muscular atrophy

A study by scientists from the Motor Neuron Center at Columbia University Medical Center (CUMC) suggests that spinal muscular atrophy (SMA), a genetic neuromuscular disease in infants and children, results primarily from motor circuit dysfunction, not motor neuron or muscle cell dysfunction, as is commonly thought.

BUSM leads genome-wide evaluation of genetic variants associated with Parkinson's disease

Boston University School of Medicine investigators have led the first genome-wide evaluation of genetic variants associated with Parkinson's disease (PD). The study, which is published online in PLOS ONE, points to the involvement of specific genes and alterations in their expression as influencing the risk for developing PD.

EphA4 receptor may be promising target for future ALS drug

Leuven scientists (VIB/KU Leuven) are using zebrafish as a model in their search for genes that play a role in the mechanism of amyotrophic lateral sclerosis (ALS). As a result, they have identified a molecule that could be the target for a future ALS treatment.

Research focuses on evolution of sex and gamete function

The propagation of every animal on the planet is the result of sexual activity between males and females of a given species. But how did things get this way? Why two sexes instead of one? Why are sperm necessary for reproduction and how did they evolve? These as-yet-unresolved issues fascinate Timothy Karr, a developmental geneticist and evolutionary biologist at Arizona State University's Biodesign Institute.

Nematode worms help identify potential cancer targets

Through novel experiments involving small nematode worms, scientists from Wyoming have discovered several genes that may be potential targets for drug development in the ongoing war against cancer. Specifically, researchers hypothesize that inhibiting these genes could reverse certain key traits associated with cancer cells.

Researchers uncover 9 new genes associated with bone health

Researchers have uncovered 9 new genes associated with bone health. This collaborative study found clues to the cause of bone disorders such as osteoporosis, osteogenesis imperfecta, and high bone density syndromes by investigating the bone mineral content, strength and flexibility.

Zebrafish provides insight into human melanoma

A transparent member of the minnow family is providing researchers at Weill Cornell Medical College in New York City with insight into human melanoma - a form of skin cancer - that may lead to new or repurposed drug treatments, for skin and other cancers.

Researchers uncover cellular basis for age-related breast cancer vulnerability

It is well-known that the risks of breast cancer increase dramatically for women over the age of 50, but what takes place at the cellular level to cause this increase has been a mystery. Some answers and the possibility of preventative measures in the future are provided in a new study by researchers at the U.S. Department of Energy (DOE)'s Lawrence Berkeley National Laboratory.

Researchers identify mechanism by which Zds1 protein regulates key function in mitosis

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) have identified the mechanism by which protein Zds1 regulates a key function in mitosis, the process that occurs immediately before cell division.

IU biologist to genetically modify variants of chlamydia

An Indiana University biologist has been awarded over $2.3 million from the National Institutes of Health to genetically modify variants of the human pathogen chlamydia in hopes of finding a vaccine for the most commonly reported bacterial infectious disease in the United States.

Human diseases with Drosophila counterparts discussed at annual conference

More than two-thirds of human genes have counterparts in the well-studied fruit fly, Drosophila melanogaster, so although it may seem that humans don't have much in common with flies, the correspondence of our genetic instructions is astonishing. In fact, there are hundreds of inherited diseases in humans that have Drosophila counterparts.
