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.

Alexion to acquire 100% of capital stock of Enobia

Alexion Pharmaceuticals, Inc. and Enobia Pharma Corp. today announced that the companies have signed a definitive agreement under which Alexion will acquire 100% of the capital stock of Enobia.

Speedy drug metabolism more likely to cause multidrug-resistant TB

A UT Southwestern Medical Center study using a sophisticated "glass mouse" research model has found that multidrug-resistant tuberculosis (TB) is more likely caused in patients by speedy drug metabolism rather than inconsistent doses, as is widely believed.

New initiative to detect cancers in earliest stages inside cells

A team of cancer imaging experts at Johns Hopkins has embarked on a five-year research initiative to speed development of early diagnostic tests and new treatments for breast, prostate and other common cancers.

Study linking chronic fatigue syndrome with virus infection retracted

The study published in the journal Science in October 2009, which found an association between the illness and a mouse leukemia retrovirus known as XMRV, was retracted last week by the editors of the journal.

Meta-analysis does not find significant association between CYP2C19 genotype and cardiovascular events

Although the U.S. Food and Drug Administration (FDA) has recommended that a certain type of genetic testing (for the genotype CYP2C19) be considered before prescribing the drug clopidogrel to identify individuals who may be less responsive to the medication, a review and analysis of previous studies did not find an overall significant association between the CYP2C19 genotype and cardiovascular events.

DNA stays too tightly wound in brain cells of patients with schizophrenia

Scientists at The Scripps Research Institute have discovered that DNA stays too tightly wound in certain brain cells of schizophrenic subjects. The findings suggest that drugs already in development for other diseases might eventually offer hope as a treatment for schizophrenia and related conditions in the elderly.

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.

Current scientific understanding of left and right-handedness

Left-handedness is sometimes the expression of a genetic defect or an early developmental disturbance. In this issue of Deutsches Ärzteblatt International, Stefan Gutwinski and coauthors present the current scientific understanding of left- and right-handedness.

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.

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.

Potential new strategy against bacteria with multi-drug resistant organisms

Vaccines with broader reach might be made by stimulating specialized immune cells to recognize foreign cell membrane proteins that are shared across bacterial species, say researchers from Children's Hospital of Pittsburgh of UPMC and the University of Pittsburgh School of Medicine in a report published online today in Immunity.

Federal officials seek to keep details on bird flu study secret

A federal board has asked two scientific journals to restrict access to details of a genetic study of the bird flu in which researchers altered the virus to be more easily transmittable between humans.

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 present results from 31 major studies of blood-related cancers at ASH 2011 meeting

Researchers from the John Theurer Cancer Center at Hackensack University Medical Center, one of the nation's top 50 best hospitals for cancer, presented results from 31 major studies of blood-related cancers - leukemia, lymphoma and multiple myeloma -- during the American Society of Hematology (ASH) Annual Meeting, December 10-13, 2011 in San Diego.
