Gene therapy used to treat periodontal disease

Scientists at the University of Michigan have shown that gene therapy can be used to successfully stop the development of periodontal disease, the leading cause of tooth loss in adults.

Enzyme that mutates antibodies also targets cancer-causing gene

The human immune system is in a perpetual state of self-experimentation. It expertly mutates and shuffles the DNA of its own cells to evolve new defenses against the vast array of microbes that try to invade our bodies.

Researchers capture never before seen undulations of "dancing chromosomes"

The rhythm of life may beat far deeper than anyone previously thought. And it may gyrate and pulse in a way that rivals the sensuous choreography of "Dirty Dancing."

Scientists show that HIV's evolution in the body does not occur at a constant rate

HIV is so deadly largely because it evolves so rapidly. With a single virus as the origin of an infection, most patients will quickly come to harbor thousands of different versions of HIV, all a little bit different and all competing with one another to most efficiently infect that person's cells. Its rapid and unique evolution in every patient is what allows HIV to evade the body's defenses and gives the virus great skill at developing resistance to a pantheon of antiviral drugs.

Men inherit tendency to have more sons or more daughters from their parents

A Newcastle University study involving thousands of families is helping prospective parents work out whether they are likely to have sons or daughters.

Enzyme that mutates antibodies also targets a cancer-causing oncogene

Rockefeller University scientists have discovered that the same enzyme that enables the immune system's defensive creativity is also responsible for a particular genetic malfunction - a translocation of one piece of DNA to the wrong chromosome - that causes Burkitt's lymphoma.

Cause of uveal melanoma discovered, most common eye cancer

A University of British Columbia geneticist has discovered a gene mutation that can cause the most common eye cancer - uveal melanoma.

RNA interference can facilitate vaccine development

Pharmaceutical companies and universities are racing to develop drugs that use the gene silencing mechanism known as RNA interference to treat a host of diseases.

Researchers find inherited genetic variation in nicotine addiction

A new study from the Abramson Cancer Center and Department of Psychiatry in the University of Pennsylvania School of Medicine shows that smokers who carry a particular version of a gene for an enzyme that regulates dopamine in the brain may suffer from concentration problems and other cognitive deficits when abstaining from nicotine - a problem that puts them at risk for relapse during attempts to quit smoking.

Irritable bowel may be genetic

Irritations of the bowel can have genetic causes. Researchers at the Institute of Human Genetics at Heidelberg University Hospital have discovered this correlation.

Carrier screening for spinal muscular atrophy should be offered to all couples

Carrier screening for spinal muscular atrophy (SMA) - a serious genetic disease affecting approximately 1 in 10,000 infants that causes progressive muscle weakness and death - should be made available to all families, according to a new practice guideline issued by the American College of Medical Genetics (ACMG).

Genetic markers identified for alcohol response

Researchers at the UCSF Ernest Gallo Clinic and Research Center have identified a region on the human genome that appears to determine how strongly drinkers feel the effects of alcohol and thus how prone they are to alcohol abuse.

New research points to possible treatment for Lou Gehrig's disease

There are many ways to die, but amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease must be one of the worst.

New therapeutic targets for malaria

Scientists working on a common antimicrobial compound with antimalarial activity have discovered a range of new therapeutic strategies to combat malaria.

Decreased levels of binding gene affect memory and behavior

Reducing the activity of a gene called FKBP12 in the brains of mice affected neuron-to-neuron communication (synapse) and increased both fearful memory and obsessive behavior, indicating the gene could provide a target for drugs to treat diseases such as autism spectrum disorder, obsessive-compulsive disease and others, said researchers from Baylor College of Medicine in Houston in a report in the current issue of the journal Neuron.

Researchers map changing epigenetic modifications that enable transposons to run amok

Cold Spring Harbor, N.Y. – Much like cancer cells, plant cells grown for a long time outside of their normal milieu, in culture dishes, have highly unstable genomes.

Brain deletion of FK506-binding protein enhances repetitive behaviors in mice

A new study reveals a link between dysregulation of a common signaling pathway and repetitive behaviors similar to those associated with multiple neurological and neurodegenerative disorders including, autism spectrum disorders, obsessive compulsive disorder, schizophrenia, and Huntington's disease.

Siblings of mentally disabled face own lifelong challenges

People who have a sibling with a mental illness are more likely to suffer episodes of depression at some point in their lives, say researchers who analyzed four decades of data.
