Reovirus may be able to eliminate cancer cells from autologous stem cell transplants

Medical studies show that a common virus may be able to eliminate cancer cells from autologous stem cell transplants.

Animals diseases jumping to humans faster than ever before

According to scientists in the U.S. and Scotland, 75% of the 38 species of harmful organisms and viruses identified in the past 25 years are believed to have "jumped" from animals to humans.

Removing a gene involved in repairing damaged DNA causes metabolic syndrome

Removing a gene involved in repairing damaged DNA causes mice to develop the metabolic syndrome, researchers at Oregon Health & Science University have discovered.

Using neural growth factor could allow researchers to mass produce stem cells for treatment of disease

Human embryonic stem cells (hES) offer great hope for the treatment of some devastating diseases, but finding a way to keep enough of these cells usable and healthy for transplantation in patients has been an ongoing problem.

Britain too laid back about bird flu

Despite the fact that France's first-known case of the deadly H5N1 strain of avian flu was found in a duck which is a winter migrant to Ireland and western Britain from Russia and Eastern Europe, authorities in the UK appear to have no immediate plans to order Britain's 25 million free-range chickens to be kept indoors.

Death toll reaches 93 as bird flu hits India, France and Egypt

Health officials in India say they have found the country's first cases of the deadly H5N1 strain of bird flu, following the death of chickens from the virus on poultry farms in the western town of Navapur.

Bird flu gets a grip on Europe

The European Union has agreed to adopt new measures in an effort to control the hold bird flu appears have gained in the region.

GeneDesign speeds design of artificial pieces of DNA

Johns Hopkins researchers have announced the development of a Web-based, automated computer program that they say greatly simplifies the time-consuming and error-prone process of manually designing artificial pieces of DNA.

Vitamin E is one of the first lines of defense in human lung tissue against the ravages of cigarette smoke

A new study has found that supplements of vitamin C can largely stop the serious depletion of vitamin E that occurs in smokers, demonstrating for the first time in humans a remarkable interaction between these two antioxidants as they work together.

Inactivating Rad9 protien could make cancer cells easier to kill with ionizing radiation

The researchers found that Rad9, previously considered a "watchman" that checks for DNA damage, is actually a "repairman" that fixes dangerous breaks in the DNA double helix. They found Rad9 is especially active in telomeres, the protective ends of chromosomes.

Farnesyltransferase inhibitor may improve progeria

UCLA researchers found that an experimental cancer drug improves the signs of progeria in a mouse model. Progeria is a rare genetic disease causing accelerated aging and cardiovascular disease in children. The new UCLA findings help to define a new strategy for treating children with progeria.

Scientists map brain area that may help find human brain stem cells

A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells.

Adjuvant hormonal therapy reduces contralateral breast cancer risk

The risk for a new cancer in the unaffected breast substantially increases in women diagnosed with unilateral, hereditary (non-BRCA) breast cancer, according to a new study.

Genetics of human muscular dystrophy

Various forms of human muscular dystrophy result from mutations in genes encoding proteins of the nuclear envelope. A new paper in the February 15th issue of G&D reveals how.

Research suggests that a common mechanism may underlie a variety of protein folding diseases

Misfolded and damaged proteins are common to all human neurodegenerative diseases. Clumps of these aggregated proteins destroy neurons within the brain and cause disease.

Hormone aldosterone linked to quality of hearing

Researchers have linked a hormone known to adjust levels of key brain chemicals to the quality of our hearing as we age. The more of the hormone that older people have in their bloodstream, the better their hearing is, and the less of the hormone, the worse their hearing is.

Cost of sexuality in microbes

The next time you mutter about the high cost of relationship maintenance, take comfort in knowing that microbes share your pain.

Less is more hypothesis - gene loss may explain unique human traits

Humans and chimps share most of their genes, yet they differ dramatically in many ways - their walk, the sizes of their brains and their capacities for speech and language, for example.

New insight into pathogenic mechanisms underlying basal-like breast cancers

Basal-like breast cancers (BLC) are highly aggressive tumors with a relatively poor prognosis that account for approximately 15% of sporadic human breast cancer.

Broccoli, cauliflower and cabbage help repair damaged DNA

Need another reason to eat your vegetables? New research shows that some of them contain chemicals that appear to enhance DNA repair in cells, which could lead to protection against cancer development, say Georgetown University Medical Center researchers.
