Gene mutation in Tibetian Terrier dogs causes hereditary form of Parkinson's disease in humans

University of Missouri researchers believe both man and animal will benefit from their discovery that the same gene mutation found in Tibetan Terrier dogs can also be found in a fatal human neurological disorder related to Parkinson's disease.

Exacerbate-reverse' approach can identify potential therapy for fatal childhood disease

Many genes that cause human diseases have parallel genes in other organisms, including yeast. Now Columbia University researchers have used an innovative yeast-based screening method to identify a possible treatment for the fatal childhood disease Niemann-Pick C.

Current thoughts, behaviour can predict future mood swings in bipolar patients

The future mood swings of people with bipolar disorder can be predicted by their current thoughts and behaviour, a study published today has found.

Mother's diet during pregnancy can influence child's risk of obesity

Scientists have discovered that a mother's nutrition during pregnancy can strongly influence her child's risk of obesity many years later.

Study finds more evidence linking high-grade serous ovarian cancer to fallopian tubes

High-grade serous ovarian cancer (HGSOC), the fifth-deadliest cancer among American women, is thought by many scientists to often be a fallopian tube malignancy masquerading as an ovarian one. While most of the evidence linking HGSOC to the fallopian tubes has so far been only circumstantial, a new Dana-Farber Cancer Institute study suggests there is a direct connection, a finding that could aid in the development of better treatments for the cancer.

Tweaking gene in satellite cells may increase lifespan of people with muscular dystrophy

Researchers have long questioned why patients with Duchenne muscular dystrophy (DMD) tend to manage well through childhood and adolescence, yet succumb to their disease in early adulthood, or why elderly people who lose muscle strength following bed rest find it difficult or impossible to regain.

Scientists identify networks of genes critical in embryonic-heart development

Scientists at the Gladstone Institutes have identified networks of genes that play an important role in embryonic-heart development, advancing knowledge of how healthy hearts develop-and offering clues about how to combat a common birth defect known as congenital heart disease.

First ever genome scan for womb cancer reveals genetic region that reduces risk of the disease

Scientists have carried out the first ever genome scan for womb cancer and discovered a genetic region that reduces risk of the disease, according to a study published in Nature Genetics.

Intellectual disability may have genetic origin, but is not hereditary

Mutations in a group of genes associated with brain activity frequently cause intellectual disability, according to a study led by scientists affiliated with the University of Montreal and the research centre at the Centre hospitalier universitaire Sainte-Justine. Intellectual disability is a severe handicap that affects between one and two percent of children worldwide. It can often be attributed to genetic causes, but the specific genes involved were mostly unknown.

Eye physicians need to include low-cost molecular medicine in their tool box

Dr. Richer, speaking at his 4th annual Nutrition & The Eye conference, April 16-17, hosted by the College of Optometry at the University of Missouri in St. Louis, says molecular medicine is beginning to provide hope for patients with declining sight when all other therapies have been exhausted.

Team of researchers study development of mesoderm

During the development of an embryo, a large number of different, specialised cell-types arise from the fertilised egg. The genetic information is identical in all cells of an organism. Different properties of cells arise because the activity of genes is controlled and regulated by so called transcription factors. By switching genes on or off, the body makes muscle cells, bone cells, liver cells and many more.

NIH researchers survey landscape of melanoma genome

A team led by researchers at the National Institutes of Health is the first to systematically survey the landscape of the melanoma genome, the DNA code of the deadliest form of skin cancer. The researchers have made surprising new discoveries using whole-exome sequencing, an approach that decodes the 1-2 percent of the genome that contains protein-coding genes.

New approach links cancer cell metabolism with poor clinical outcome

Identifying gene mutations in cancer patients to predict clinical outcome has been the cornerstone of cancer research for nearly three decades, but now researchers at the Kimmel Cancer Center at Jefferson have invented a new approach that instead links cancer cell metabolism with poor clinical outcome. This approach can now be applied to virtually any type of human cancer cell.

FEN1 enzyme might serve as anti-cancer therapy target

An enzyme essential for DNA replication and repair in humans works in a way that might be exploited as anti-cancer therapy, say researchers at The Scripps Research Institute and Lawrence Berkeley National Laboratory.

Scientists identify novel small molecules that block human tumor cell growth

Researchers from the Cancer Institute at NYU Langone Medical Center have identified three novel small molecules that interrupt a crucial cellular communication pathway that regulates many aspects of development and cancer.

Nurses use ineffective strategy for adapting circadian clocks to night-time schedule

As many as 25 percent of hospital nurses go without sleep for at least 24 hours in order to adjust to working on the night shift, which is the least effective strategy for adapting their internal, circadian clocks to a night-time schedule.

Researchers temporarily turn off essential gene using RNAi technology

One way of discovering a gene's function is to switch it off and observe how the loss of its activity affects an organism. If a gene is essential for survival, however, then switching it off permanently will kill the organism before the gene's function can be determined. Researchers at Cold Spring Harbor Laboratory (CSHL) have overcome this problem by using RNA interference (RNAi) technology to temporarily turn off any essential gene in adult mice and then turn it back on before the change kills the animals.

Researchers show how TET1 enzyme controls fetal development and fights cancer

To ensure normal fetal development and prevent disease, it is crucial that certain genes are on or off in the right time intervals. Researchers in Professor Kristian Helin's group at BRIC, University of Copenhagen, have now shown how the TET1 enzyme controls the activity of our genes. The results are just published in the journal Nature.

NIAID finding to accelerate Chlamydia infection study

WHAT: In a new study from the National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, scientists describe successfully mutating specific genes of Chlamydia bacteria, which cause the most common sexually transmitted infection in the United States as well as a type of blindness common in developing nations.

Scientists discover how anti-depressants make new brain cells

For the first time in a human model, scientists have discovered how anti-depressants make new brain cells. This means that researchers can now develop better and more efficient drugs to combat depression.
