New candidate gene for human benign childhood epilepsies

A new epilepsy gene, LGI2, has been found in the Lagotto Romagnolo dogs, known from their gift for truffle hunting. The gene discovery made by Professor Hannes Lohi and his research group at the University of Helsinki and the Folkhälsan Rsearch Center offers a new candidate gene for human benign childhood epilepsies characterized by seizure remission.

Mitochondrial genome undergoes random reorganisation during reprogramming

Induced pluripotent stem cells (iPS cells) are truly talented multi-taskers. They can reproduce almost all cell types and thus offer great hope in the fight against diseases like Alzheimer's and Parkinson's. However, it would appear that their use is not entirely without risk: during the reprogramming of body cells into iPS cells, disease-causing mutations can creep into the genetic material.

Scientists show how RET gene in breast cancer cells responds to estrogen

Using human breast cancer cells and the protein that causes fireflies to glow, a Johns Hopkins team has shed light on why some breast cancer cells become resistant to the anticancer effects of the drug tamoxifen. The key is a discovery of two genetic "dimmer switches" that apparently control how a breast cancer gene responds to the female hormone estrogen.

Researchers identify gene linked to Lesch-Nyhan disease

In humans, inherited mutations in a gene called HPRT1 lead to very specific self-destructive behavior. Boys with Lesch-Nyhan disease experience uncontrollable urges to bite their fingers, slam their arms into doorways and otherwise harm themselves.

IRCM geneticists discover an unsuspected organization of pituitary cells

A team of geneticists at the Institut de recherches cliniques de Montr-al (IRCM), directed by Dr. Jacques Drouin, made an unexpected discovery on hormone secretion. Contrary to common belief, the researchers found that pituitary cells are organized in structured networks. The scientific breakthrough was published yesterday by the scientific journal Proceedings of the National Academy of Sciences.

Insect virus holds key to safer stem cell therapy: Singapore scientists

The future of regenerative medicine lies in harnessing the potential of the human body to renew and repair itself. Now, scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a new genetic engineering technique that promises safer stem cell therapy for cancer patients. Using an insect virus, the team of researchers successfully inserted a therapeutic gene into a safe site in the DNA of human embryonic stem cells without compromising the functionality of the engineered cells.

All football players do not get chronic traumatic encephalopathy

Preliminary results from the first four brains donated to the Canadian Sports Concussion Project at the Krembil Neuroscience Centre, TorontoWesternHospital, reveal that two of the four former Canadian Football League (CFL) players suffered from a brain disease known as Chronic Traumatic Encephalopathy (CTE), while two did not show signs of CTE.

Researchers investigate the nature of stuttering

Radio-TV-Film senior Alex Murphy has a knack for storytelling through short stories, poetry and screenwriting. One of his undergraduate classes was a professional communication course, which requires students to deliver oral presentations in class.

Scientists identify possible genetic variations linked to eating disorders

A substantial number of people with eating disorders, such as anorexia nervosa have a chronic course. They are severely underweight and have a high likelihood of dying from malnutrition. No treatment has been found that helps people who are chronically ill. Now, a new study sheds light on the reason that some people have poor outcome.

Lack of genetic screening for cancers

In a new study published Monday in the journal Cancer, it was noted that while genetic testing to check if a woman has the BRCA1 or BRCA2 mutations can be a useful tool for preventing breast cancer and ovarian cancer in some cases, many doctors are not referring patients.

Women & Infants creates fully integrated center for high-risk pregnancy

Every pregnancy deserves special treatment. But when a woman with a normal pregnancy has a complication or a woman with a medical issue becomes pregnant, she needs highly specialized care.

Researchers identify elusive gene responsible for Grey Platelet Syndrome

Researchers have identified an elusive gene responsible for Grey Platelet Syndrome, an extremely rare blood disorder in which only about 50 known cases have been reported. As a result, it is hoped that future cases will be easier to diagnose with a DNA test.

Fragile X syndrome study to reveal more

Fragile X syndrome is the most common inherited cause of intellectual disability in the world. Medical experts, including the Mater Hospital's Dr Helen Heussler, are today launching a new push to uncover the secrets of a disorder that affects a child born in Australia every week. Fragile X is passed from parent carriers who often exhibit very few symptoms. Estimates suggest more than 100,000 Australians either carry the gene mutation that causes Fragile X or have the syndrome, yet the vast majority have not been diagnosed, according to the Fragile X Association of Australia.

First high-resolution genetic maps for African American populations

UCLA life scientists and colleagues have produced one of the first high-resolution genetic maps for African American populations. A genetic map reveals the precise locations across the genome where DNA from a person's father and mother have been stitched together through a biological process called "recombination." This process results in new genetic combinations that are then passed on to the person's children.

U.S. amends human research rules

The U.S. Government has proposed major changes in the rules covering research involving human subjects. Officials believe this would strengthen protections while reducing red tape that can impede studies. The experts cited vastly altered research climate as reasons for these recommendations. New features include genomics studies using patients’ DNA samples, the use of the Internet and a growing reliance on studies that take place at many sites at once. The new rules cover topics like the informed consent that research participants must provide and the institutional review boards that oversee research at universities and hospitals.

Advancements in use of zinc finger nucleases to produce genetically modified pigs

Sangamo BioSciences, Inc. announced the publication of a study demonstrating the use of zinc finger nucleases (ZFNs) to produce genetically modified pigs. The study, which was published in the Proceedings of the National Academy of Sciences (PNAS), represents a significant advancement in the development of improved, less immunogenic animal tissue as a source for transplant into humans.
