WHO issues warning about risks of research on human engineered bird flu

"The World Health Organization issued a stern warning on Friday to scientists who have engineered a highly pathogenic form of the deadly H5N1 bird flu virus, saying their work carries significant risks and must be tightly controlled," Reuters reports.

Researchers identify gene required for proper development of mouse inner ear

Providing clues to deafness, researchers at Washington University School of Medicine in St. Louis have identified a gene that is required for proper development of the mouse inner ear.

Bird flu updates

The latest bird flu virus that killed a 39-year-old bus driver in the southern Chinese city of Shenzhen over the weekend is not yet transmissible between humans, Chinese health authorities said. The man, who lived in Shenzhen just across the border from Hong Kong, died from multi-organ failure on Saturday, a week after being admitted to hospital with a fever brought on by the virus, state media reported.

TrovaGene acquires license to mutations of SF3B1 splicing factor in CLL

TrovaGene, Inc., a developer of trans-renal molecular diagnostics, today announced that it has obtained an exclusive worldwide license to mutations of the SF3B1 splicing factor, which have been shown to be associated with disease progression and chemotherapy response in patients suffering from chronic lymphocytic leukemia.

Van Andel studies distinguish cancer subtypes and provide promising new drug targets

Two recent studies by Van Andel Research Institute scientists are providing a foundation for a more complete understanding of distinct kidney cancer subtypes, which could pave the way for better treatments.

Four-year effort to map genetic code of 1,000 African-Americans

A Johns Hopkins-led team of experts in genetics, immunology, epidemiology and allergic disease has embarked on a four-year effort to map the genetic code, or whole genome, of 1,000 people of African descent, including men and women from Baltimore.

ATM gene mutations may increase hereditary risk for pancreatic cancer

Mutations in the ATM gene may increase the hereditary risk for pancreatic cancer, according to data published in Cancer Discovery, the newest journal of the American Association for Cancer Research.

Researchers decode and characterize DNA repair mechanism

Oxidative stress is the cause of many serious diseases such as cancer, Alzheimer's, arteriosclerosis and diabetes. It occurs when the body is exposed to excessive amounts of electrically charged, aggressive oxygen compounds. These are normally produced during breathing and other metabolic processes, but also in the case of ongoing stress, exposure to UV light or X-rays. If the oxidative stress is too high, it overwhelms the body's natural defences. The aggressive oxygen compounds destroy genetic material, resulting in what are referred to as harmful 8-oxo-guanine base mutations in the DNA.

Tbx3 dysfunction may cause acquired and spontaneous arrhythmias

In a study published in the Dec. 26, 2011, Proceedings of the National Academy of Sciences early edition, researchers led by the University of Utah showed the CCS is extremely sensitive to levels of Tbx3. Mouse embryos with Tbx3 levels below a critical threshold suffered arrhythmia and couldn't survive. As the levels of Tbx3 were increased, mice survived to birth, but as adults they developed arrhythmias or had sudden death.

Neuroscientists discover gene responsible for HDLS

A global team of neuroscientists, led by researchers at Mayo Clinic in Florida, have found the gene responsible for a brain disorder that may be much more common than once believed. In the Dec. 25 online issue of Nature Genetics, the researchers say they identified 14 different mutations in the gene CSF1R that lead to development of hereditary diffuse leukoencephalopathy with spheroids.

Biologists develop radar to track ADAR's RNA editing activity in neurons

To track what they can't see, pilots look to the green glow of the radar screen. Now biologists monitoring gene expression, individual variation, and disease have a glowing green indicator of their own: Brown University biologists have developed a "radar" for tracking ADAR, a crucial enzyme for editing RNA in the nervous system.

Genetic analysis revises treatment recommendations related to thyroid cancer

Cleveland Clinic researchers have discovered three genes that increase the risk of thyroid cancer, which is has the largest incidence increase in cancers among both men and women.

LincRNAs play key roles during embryonic brain development

Whitehead Institute scientists have identified conserved, long intervening non-coding RNAs (lincRNAs) that play key roles during embryonic brain development in zebrafish. They also show that the human versions of the lincRNAs can substitute for the zebrafish versions, which implies that the functions of these non-coding RNAs have been retained in humans as well as fish.

Researchers successfully treat severe congenital disorder in mouse model

Using a mouse model, Heidelberg University Hospital researchers have for the first time successfully treated a severe congenital disorder in which sugar metabolism is disturbed.

Scientists discover how DNA mismatch repair proteins work

In eukaryotes - the group of organisms that include humans - a key to survival is the ability of certain proteins to quickly and accurately repair genetic errors that occur when DNA is replicated to make new cells.

Researchers identify previously unknown gene fusion event in lung cancer

Smoking is a well-known risk factor for lung cancer, but nearly 25% of all lung cancer patients have never smoked. In a study published online today in Genome Research, researchers have identified a previously unknown gene fusion event that could explain a significant proportion of lung cancer cases in never-smokers, and might serve as a target for new therapies.

New way to awaken paternal Ube3a allele linked with Angelman syndrome

Results of a new study from the University of North Carolina at Chapel Hill may help pave the way to a treatment for a neurogenetic disorder often misdiagnosed as cerebral palsy or autism.

Researchers discover how c-MYC facilitates tumor growth

Cancer cells are essentially immortal. The acquisition of an unlimited capacity to divide - the process of immortalization - is a central event in the genesis of tumors. Normally, cells are subject to stringent mechanisms which control their proliferation. Together these ensure that pre-malignant cells are induced to enter a senescent, non-dividing state or to undergo apoptosis, i.e. commit suicide.

CNVs appear to play a significant role in early onset bipolar disorder

An international team of scientists, led by researchers at the University of California, San Diego School of Medicine, reports that abnormal sequences of DNA known as rare copy number variants, or CNVs, appear to play a significant role in the risk for early onset bipolar disorder.

ORNL tool reveals previously undiscovered role of retinoblastoma

Armed with a new ability to find retinal anomalies at the cellular level, neurobiologists at St. Jude Children's Research Hospital have made a discovery they hope will ultimately lead to a treatment for cancer of the retina.
