Hastings Center Report examines ethical controversies over use of personalized medicine

As government support for personalized medicine grows, a consumer advocate, a patient, and bioethicists explore ethical controversies. Direct-to-consumer genetic tests, privacy, targeted cancer therapies, and Henrietta Lacks are among topics in a special issue of the Hastings center Report

Scientists develop computer model to examine genetic switch for TB dormancy

An examination of a portion of the tuberculosis genome that responds to stress has allowed Rice University bioengineers Oleg Igoshin and Abhinav Tiwari to zero in on a network of genes that may "switch" the disease into dormancy.

Scientists discover simple blood test for accurate diagnoses of liver damage

Scientists have discovered that the presence of specific proteins in the blood are indicative of early liver cell damage and can determine the point at which cell death occurred, the type of cell death, and the extent of any damage. This could lead to liver damage being assessed faster and more accurately in the future information which could prove valuable when treating people following drug overdoses.

Lawmakers debate action on stem cell research, public health bills

Sen. Arlen Specter said at a Senate hearing Thursday that Congress should move on allowing the government to fund human embryonic stem cell research "to avoid giving a final say on the issue to a conservative Supreme Court," The Associated Press reports.

Penn study reveals structure of cell division's key molecule

On average, one hundred billion cells in the human body divide over the course of a day. Most of the time the body gets it right but sometimes, problems in cell replication can lead to abnormalities in chromosomes resulting in many types of disorders, from cancer to Down Syndrome.

APC gene mutation affects DNA methylation in colon cancer: Research

Colon cancer is the second most common cancer in the United States and causes more than 50,000 deaths each year. It has been known for some time that mutations in the APC gene occur in more than 85 percent of all sporadic colon cancers. Now researchers at Huntsman Cancer Institute at the University of Utah demonstrate in a study featured today in Cell the mechanism by which mutation of the APC gene affects a cellular process known as DNA methylation.

Disabling RGS14 gene helps mice remember better

Deleting a certain gene in mice can make them smarter by unlocking a mysterious region of the brain considered to be relatively inflexible, scientists at Emory University School of Medicine have found.

Researchers identify new target for cystic fibrosis

The lab of Kevin Foskett, PhD, the Isaac Ott Professor of Physiology at the University of Pennsylvania School of Medicine, has found a possible new target for fighting cystic fibrosis (CF) that could compensate for the lack of a functioning ion channel in affected CF-related cells. Their finding appears in the Journal of Clinical Investigation.

Researchers discover evolutionary nature of bacteria to spread chronic infectious disease

Researchers from the Center for Genomic Sciences at Allegheny General Hospital (AGH) in Pittsburgh have made a landmark discovery about the evolutionary nature of bacteria in the setting of chronic infectious disease. Reporting today in the journal PLos Pathogens, the AGH team documents for the first time that bacteria engage in a process called horizontal gene transfer to evolve rapidly during the course of a single infection.

Conference to discuss frontline of immunological research, its clinical application

The immune system is evolved to protect our body against a variety of infectious agents which can cause serious and often fatal diseases. We now appreciate that the immune system is also involved in surveillance of malignant transformation of normal cells that constitute our body, as well as rejection of transplanted organs.

Biomedical applications of 'warrior worms' in snails

Scientists at UC Santa Barbara have discovered a caste of genetically identical "warrior worms" -- members of a parasitic fluke species that invades the California horn snail. The findings are reported in the early online version of the Proceedings of the Royal Society B.

Blood vessel growth promoting microRNA predicts diabetes: Study

For the first time, scientists have found that blood levels of some ribonucleic acids (microRNAs) are different among people with type 2 diabetes and those who subsequently develop the disease compared to healthy controls, according to research reported in Circulation Research: Journal of the American Heart Association.

Global regulator for DNA trade needed

Amid growing concern that synthetic life sciences pose biosecurity and biosafety risks, scrutiny is increasing into the burgeoning DNA sequence trade. Research published today in the Bulletin of the Atomic Scientists, published by SAGE, looks at the necessity of a global regulator for DNA trade, and the significant barriers to creating one.

76% of Americans oppose cloning human embryos for research

As the U.S. Senate prepares to hold a hearing on human embryonic stem cell research (hESCR), a new public opinion poll shows that a plurality of Americans (47 percent) oppose federal funding of stem cell research that involves destroying human embryos, while only thirty-eight percent (38 percent) support such funding. The poll, conducted by ICR / International Communications Research, surveyed 1,006 adults September 8-14. It was commissioned by the Secretariat of Pro-Life Activities at the U.S. Conference of Catholic Bishops (USCCB).

New genetic analysis technique isolates culprit gene in families with inherited single-gene kidney diseases

A University of Michigan-led research team has identified a gene responsible in some families for a devastating inherited kidney disorder, thanks to a new, faster method of genetic analysis not available even two years ago. The success offers hope that scientists can speed the painstaking search for the genes responsible for many rare diseases and test drugs to treat them.

Researchers load biological molecules onto 'nanosprings'

Researchers at Oregon State University have reported the successful loading of biological molecules onto "nanosprings" - a type of nanostructure that has gained significant interest in recent years for its ability to maximize surface area in microreactors.

Simian immunodeficiency virus is at least 32,000 to 75,000 years old

An ancestor of HIV that infects monkeys is thousands of years older than previously thought, suggesting that HIV, which causes AIDS, is not likely to stop killing humans anytime soon, finds a study by University of Arizona and Tulane University researchers.

Research on signaling pathways may help to design therapy for neurodevelopmental disorders

Researchers at the Center for Neuroscience Research at Children's National Medical Center have discovered that the two major types of signaling pathways activated during brain cell development-the epidermal growth factor receptor pathway and the Notch pathway-operate together to determine how many and which types of brain cells are created during growth and repair in developing and adult brains.
