Genentech receives FDA approval for Actemra to treat juvenile idiopathic arthritis

The U.S. Food and Drug Administration today approved Actemra, given alone or in combination with methotrexate, for the treatment of active systemic juvenile idiopathic arthritis in children ages 2 years and older.

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.

Cytonet initiates clinical trial using liver cell infusion to treat urea cycle disorders in children

International biotechnology firm Cytonet recently launched the first ever clinical trial in the United States using an investigational liver cell infusion to treat urea cycle disorders (UCD) in children. The first patient in the Phase II trial, which will seek to enroll 20 patients in 12 medical centers, is a child with citrullinemia, which is a hereditary UCD. He received six liver cell infusions on six consecutive days at Yale School of Medicine in New Haven, Conn.

New treatment improves immune function in 13-year-old with Wiskott-Aldrich syndrome

In a novel approach that works around the gene defect in Wiskott-Aldrich syndrome, an inherited immune deficiency disorder, researchers used an alternative cell signaling pathway to significantly improve immune function in a 13-year-old boy with the disease.

Astrocytes regulate circadian system that controls normal sleep patterns

The circadian system that controls normal sleep patterns is regulated by a group of glial brain cells called astrocytes, according to a study published online on April 14th in Current Biology, a Cell Press publication. Neuroscientists from Tufts University School of Medicine found that disruption of astrocyte function in fruit flies ( Drosophila) led to altered daily rhythms, an indication that these star-shaped glial cells contribute to the control of circadian behavior.

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.

Researchers pinpoint new approach that can treat pediatric leukemia

A Loyola University Health System study points to a promising new approach to treating an aggressive and usually fatal leukemia in babies.

Organic pollutants in flame retardents cause molecular changes in reproductive organs

Polybrominated diphenyl ethers (PBDEs) are chemicals that have been widely used as flame retardants and are now classified as persistent organic pollutants. Health concerns in humans have arisen based primarily on studies with laboratory animals exposed to high levels of PBDEs. Three commercial mixtures of PBDEs have been manufactured in or imported into the United States which include penta-, octa-, and deca-brominated diphenyl ethers (BDEs).

Insight into Cervical Spondylotic Myelopathy

Researchers at the Krembil Neuroscience Centre, Toronto Western Hospital have identified a cell receptor, which is responsible for cell death in the spinal cord in a condition called Cervical Spondylotic Myelopathy.

Researchers develop Short-CGH method for preimplantation genetic screening

A Short Comparative Genomic Hybridisation method has been developed to carry out preimplantation genetic screening by analysing all chromosomes and transferring selected embryos to the recipient uterus in the same in vitro fertilisation cycle. This eliminates the need to freeze them.

Researchers report injectable gel can help treat arthritis

Some 25 million people in the United States alone suffer from rheumatoid arthritis or its cousin osteoarthritis, diseases characterized by often debilitating pain in the joints. Now researchers at Brigham and Women's Hospital report an injectable gel that could spell the future for treating these diseases and others.

Researchers classify chronic ulcerative stomatitis as a new autoimmune disease

In the first study investigating the origins of a little-known condition called chronic ulcerative stomatitis, researchers at Tufts University School of Dental Medicine provide evidence that an autoimmune response contributes to the painful oral sores that characterize the disease. The study findings support the classification of CUS as a new autoimmune disease.

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.

Normal breast cells provide an innate defense mechanism against cancer

It is well known that the human body has a highly developed immune system to detect and destroy invading pathogens and tumor cells. Now, researchers at the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the body has a second line of defense against cancer - healthy cells.

Sea squirt study may help solve organ rejection problems in humans

Studies of the small sea squirt may ultimately help solve the problem of rejection of organ and bone marrow transplants in humans, according to scientists at UC Santa Barbara.

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.

NIST's new reference can aid in Huntington's disease diagnosis

A new Standard Reference Material from the National Institute of Standards and Technology will help clinical genetics labs accurately diagnose Huntington's disease, an inherited degenerative brain disorder that usually begins between ages 35 and 50 and progressively leads to physical impairment, dementia and death.

Scientists link increase of calcium influx in brain neurons to long-term memory

Using advanced imaging technology, scientists from the Florida campus of The Scripps Research Institute have identified a change in chemical influx into a specific set of neurons in the common fruit fly that is fundamental to long-term memory.

Scientists identify filter neurons that can reduce 'brain clutter'

Until now, it has been assumed that people with diseases like ADHD, Tourette syndrome, obsessive compulsive disorder and schizophrenia - all of whom characteristically report symptoms of "brain clutter" - may suffer from anomalies in the brain's prefrontal cortex.

Novartis, Duke sign deal to develop pandemic flu vaccine

The Duke Human Vaccine Institute today announced a collaboration and strategic agreement with Novartis Vaccines and Diagnostics to enable the rapid development of a vaccine and accelerate preparedness in case of a pandemic virus threat such as pandemic influenza.
