Tel Aviv University scientists work to determine how H1N1 becomes pandemic

The last century has seen two major pandemics caused by the H1N1 virus - the Spanish Flu in 1918 and 2009's Swine Flu scare, which had thousands travelling with surgical masks and clamoring for vaccination. But scientists did not know what distinguished the Swine Flu from ordinary influenza in pigs or seasonal outbreaks in humans, giving it the power to travel extensively and infect large populations.

New role for harmonin protein in Usher syndrome

University of Iowa scientists have discovered a new role for a protein that is mutated in Usher syndrome, one of the most common forms of deaf-blindness in humans. The findings, which were published Aug. 8 in Nature Neuroscience, may help explain why this mutation causes the most severe form of the condition.

Mice with enzyme deficiency are unable to properly assess threat

Do you run when you should stay? Are you afraid of all the wrong things? An enzyme deficiency might be to blame, reveals new research in mice by scientists at the University of Southern California.

New technique can help develop HIV vaccines

Researchers have traced in detail how certain powerful HIV neutralizing antibodies evolve, a finding that generates vital clues to guide the design of a preventive HIV vaccine, according to a study appearing in Science Express this week.

Research team reports first genetic sequencing of urothelial carcinoma

In an article published online this week in Nature Genetics, a University of Colorado Cancer Center team in partnership with universities in China and Denmark reports the first genetic sequencing of urothelial (transitional) carcinoma, the most prevalent type of bladder cancer.

G-CSF therapy does not induce chromosomal instability in healthy stem cell donors

According to a study published in Blood, the Journal of the American Society of Hematology (ASH), researchers have reported that administration of granulocyte colony-stimulating factor (G-CSF), a drug that releases stem cells from the bone marrow into the blood, is unlikely to put healthy stem cell donors at risk for later development of abnormalities involving loss or gains of chromosomes that have been linked to hematologic disorders such as myelodysplastic syndromes (MDS) and acute myeloid leukemia.

New model for amyotrophic lateral sclerosis

By isolating cells from patients' spinal tissue within a few days after death, researchers funded by the National Institutes of Health have developed a new model of the paralyzing disease amyotrophic lateral sclerosis.

SIGMAR1 gene mutation associated with development of juvenile ALS

Researchers from the Kingdom of Saudi Arabia have identified a mutation on the SIGMAR1 gene associated with the development of juvenile amyotrophic lateral sclerosis.

Genetic culprit behind ovarian cancer discovered

A study has revealed that a single fault in a gene that normally helps the body to repair its DNA increases a woman's risk of ovarian cancer six-fold. One in every 11 women who carry the faulty gene is likely to develop ovarian cancer at some point in her life compared with a typical risk of about one in 70 for women in the general population, scientists said.

Study suggests link between gene variant and Proteus syndrome

Orthopaedic surgeons from Children's National Medical Center are part of a team of researchers that has identified the genetic mutation causing Proteus syndrome, a rare disorder in which tissue and bone grow massively out of proportion.

Scientist determines how nyctalopin gene makes night vision possible

A scientist from the Florida campus of The Scripps Research Institute has determined how a particular gene makes night vision possible. The study, which was published in the August 10, 2011 edition of The Journal of Neuroscience, focuses on a gene called nyctalopin. Mutations in the gene result in inherited "night blindness," a loss of vision in low-light environments.

New genetic cause of retinitis pigmentosa

Combining the expertise of several different labs, University of Iowa researchers have found a new genetic cause of the blinding eye disease retinitis pigmentosa (RP) and, in the process, discovered an entirely new version of the message that codes for the affected protein.

Male breast cancer patients denied Medicaid coverage

The American Cancer society's pages on breast cancer in men lay out the facts. About 2,000 men are diagnosed with breast cancer each year, which makes it rare: about 100 times more women get the disease. It is known that men, like women, are more likely to develop cancer if they have certain mutations of the BRCA1 and BRCA2 genes. Family history and age contribute to a man's likelihood of developing the disease as well.

Response Genetics second quarter total revenue increases 18.8% to $6.7 million

Response Genetics Inc., a company focused on the development and sale of molecular diagnostic tests for cancer, today announced its consolidated financial results and business progress for the second quarter ended June 30, 2011.

Schizophrenia not always inherited – Genetic links found

Researchers have found that more than half the cases of non-hereditary or sporadic schizophrenia are caused by “new” protein-altering gene mutations. These mutations are new genetic errors that appear in patients but not in either of their parents, the researchers explained in the report published in the Aug. 7 online edition of the journal Nature Genetics.

De novo mutations account for 50% of sporadic cases of schizophrenia

Columbia University Medical Center researchers have shown that new, or "de novo," protein-altering mutations—genetic errors that are present in patients but not in their parents—play a role in more than 50 percent of "sporadic" —i.e., not hereditary—cases of schizophrenia.

Specific microRNA cluster could play a key role in retinoblastoma development

New research from a team including several Carnegie scientists demonstrates that a specific small segment of RNA could play a key role in the growth of a type of malignant childhood eye tumor called retinoblastoma.

PCF funds 10 new Challenge Awards for prostate cancer research

The Prostate Cancer Foundation today announced that it has funded 10 new Challenge Awards for accelerating scientific discovery and new treatments for prostate cancer patients.

EWS protein detects and corrects DNA damage in Ewing's sarcoma

Researchers from the CRG have discovered that ultraviolet light affects the function of the protein EWS, the mutation of which is responsible for Ewing's sarcoma. The results, to be published on 5th August in the journal Molecular Cell, indicate that the EWS protein has a protective effect on DNA.

Researchers identify genes that play a key role in pain perception

By working with individuals suffering from a severe disorder that causes sensory neurons to degenerate, researchers at the University of Montreal Hospital and CHU Sainte-Justine Hospital have discovered how a specific genetic mutation causes their patients' condition, which in turn has revealed more information about the mechanisms in our bodies which enable us to sense pain.
