Possible new approach to slow the progression of cognitive decline in Down's syndrome

A study by neuroscientist William C. Mobley, MD, PhD, chair of the Department of Neurosciences at the University of California, San Diego School of Medicine, and colleagues at Stanford University Medical School has demonstrated a possible new approach to slowing the inevitable progression of cognitive decline found in Down's syndrome.

PKCI/HINT1 gene associated with mood regulation

Removing the PKCI/HINT1 gene from mice has an anti-depressant-like and anxiolytic-like effect. Researchers writing in the open access journal BMC Neuroscience applied a battery of behavioral tests to the PKCI/HINT1 knockout animals, concluding that the deleted gene may have an important role in mood regulation.

Researchers identify a new mechanism that inhibits the formation of new blood vessels

Researchers at Uppsala University, in collaboration with colleagues in Sweden and abroad, have identified an entirely new mechanism by which a specific protein in the body inhibits formation of new blood vessels. Inhibiting the formation of new blood vessels is an important aspect of, for example, cancer treatment. The study is published in the November issue of the journal Molecular Cancer Research.

Helper T cell's effect raises possibility of cellular therapy and vaccine development

A specific type of T helper cell awakens the immune system to the stealthy threat of cancer and triggers an attack of killer T cells custom-made to destroy the tumors, scientists from The University of Texas M. D. Anderson Cancer Center report in the early online edition of the journal Immunity.

Protein crucial for insulin regulation may play a role in diabetes

A cellular protein from a family involved in several human diseases is crucial for the proper production and release of insulin, new research has found, suggesting that the protein might play a role in diabetes.

Research shows exon-skipping drug may prove effective for treating Duchenne muscular dystrophy

An exon skipping PPMO has demonstrated dramatic effects in the prevention and treatment of severely affected, dystrophin and utrophin-deficient mice, preventing severe deterioration of the treated animals and extending their lifespan.

Sigma-Aldrich launches SAGEspeed, a program for developing human disease models in rodents

Sigma-Aldrich® (Nasdaq: SIAL) today announced the launch of SAGEspeed(TM), a program to develop human disease models in rodents using its proprietary novel CompoZr(TM) Zinc Finger Nuclease (ZFN) gene editing technology (http://www.compozrzfn.com).

CHEO researchers identify protein that inhibits insulin production

One of the biggest mysteries about diabetes is why specialized cells in the pancreas stop secreting insulin, which the body needs in order to store glucose from food. A team from the Children's Hospital of Eastern Ontario (CHEO) Research Institute has identified a protein that inhibits insulin production in mice - work that offers a new way of understanding, and perhaps of one day treating, both Type 1 and Type 2 diabetes.

Researchers discover that Merkel cells originate in the skin

Case Western Reserve University School of Medicine assistant professor of pediatrics, neurosciences and otolaryngology, Stephen M. Maricich, M.D., Ph.D., and his team found that Merkel cells originate in the skin, not the neural crest lineage, as previously speculated.

NEDD9 protein stimulates aggressive metastatic breast cancer

Researchers at Fox Chase Cancer Center have demonstrated that a protein called NEDD9 may be required for some of the most aggressive forms of breast cancer to grow. Their findings, based on the study of a mouse model of breast cancer, are presented in a recent issue of Cancer Research, available on-line now.

Therapeutic target for acute respiratory distress syndrome identified

Research led by Dr. Jay Kolls, Professor and Chairman of Genetics at LSU Health Sciences Center New Orleans, has identified a therapeutic target for acute lung injury resulting in acute respiratory distress syndrome, a highly fatal complication of influenza infection.

Second-quarter 2009 unaudited results announced by Deltagen

Deltagen, Inc. (Pink Sheets: DGEN), a leading provider of drug discovery tools to the biopharmaceutical industry, today reported unaudited consolidated financial results for the three months ended June 30, 2009.

Players’ fencing response yields visual clues on brain injury

Brain injury researchers at the University of Kentucky have spent hundreds of hours watching YouTube videos of people getting smacked, punched and knocked in the head during sporting events and recreational activities. But those researchers weren't goofing off on the Internet; they were doing hard science.

Amateur boxing leads to increased levels of brain damage markers in spinal fluid

A blood test can now be used to detect brain damage in amateur boxers. Deterioration of nerve cells seems to occur even after a two-month break from boxing. This is shown in a new study from the Sahlgrenska Academy, University of Gothenburg, Sweden.

Sigma-Aldrich scientists to leverage proprietary gene editing technology to develop genetically-engineered rodent research models

Sigma-Aldrich(R) (Nasdaq: SIAL) announced today that scientists at its new Sigma Advanced Genetic Engineering (SAGE(TM)) Labs in St. Louis will leverage its exclusive CompoZr(TM) Zinc Finger Nuclease (ZFN) gene editing technology (www.compozrzfn.com) to define, develop and offer a new generation of genetically-engineered rodent research models. Such models are commonly used to study disease states in humans and play a key role in the drug discovery process.

New understanding of role hyaluronic acid in skeletal growth

Investigators at Burnham Institute for Medical Research (Burnham) and the University of Connecticut Health Center (U.C.H.C.) have gained new understanding of the role hyaluronic acid (HA) plays in skeletal growth, chondrocyte maturation and joint formation in developing limbs.

Researchers expose the biology of Clostridium difficile transmission in mice

New research suggests that antibiotic treatment could be asymptomatically inducing the transmission of the healthcare-acquired infection, C. difficile, contributing to the outbreaks that have recently been widely reported in hospitals and other settings. A team of scientists have successfully mirrored the infection cycle of C. difficile by generating a 'mouse hospital' with conditions mimicking the human environment in which C. difficile is transmitted.

Newly identified gene regulates immune cells' ability to harm the body

A recently identified gene allows immune cells to start the self-destructive processes thought to underlie autoimmune diseases such as multiple sclerosis (MS) and rheumatoid arthritis, researchers at Washington University School of Medicine in St. Louis have found.
