'Mighty mice' made mightier

The Johns Hopkins scientist who first showed that the absence of the protein myostatin leads to oversized muscles in mice and men has now found a second protein, follistatin, whose overproduction in mice lacking myostatin doubles the muscle-building effect.

Gamma globulin effective treatment for pinkeye

Gamma globulin, a type of antibody isolated from blood samples that used to be routinely given to health care workers and international travelers to protect them from infectious diseases, is a highly effective treatment for pinkeye with little apparent toxicity, according to a study by researchers at the University of Pittsburgh School of Medicine.

St. Jude discovers factors that accelerate resistance to Gleevec targeted therapy in lymphoblastic leukemia

Results of a study by investigators at St. Jude Children's Research Hospital provide strong evidence for why the drug imatinib (Gleevec), which has revolutionized the treatment of chronic myelogenous leukemia (CML), is often unable to prevent relapse of a particularly aggressive form of acute lymphoblastic leukemia (ALL).

Discovery may lead to fast and cheap method of making vaccines

Researchers may be able to tinker with a single amino acid of an enzyme that helps viruses multiply to render them harmless, according to molecular biologists who say the discovery could pave the way for a fast and cheap method of making vaccines.

Circulating fats kill transplanted pancreas cells

Dietary restrictions or other strategies that limit fat formation might make pancreatic cell transplants more effective, UT Southwestern Medical Center researchers report.

New research findings on Apert's syndrome

Aperts syndrome is a condition caused by a mutation that produces fused fingers and toes, and alters cranial development in affected children.

Animal model for dengue research

A mosquito-borne disease often known as "break-bone fever" has found a new enemy in a unique type of mouse.

Scientists identifiy successfully reprogrammed cells by looks alone

Some scientific results are hard to spot, especially in genetic research. Often scientists are unable to physically see if the gene they inserted into a cell has produced the desired trait.

High stress and genetic risk factor lead to increased memory decline

High stress levels may contribute to memory loss among people at risk for developing Alzheimer's disease.

Human testes may act as mutation multipliers

The testes in humans may act as mutation multipliers that raise the odds of passing improved DNA to offspring - but that can also backfire by increasing the frequency of certain diseases.

New understanding of factor YY1 in gene expression

The Conaway Lab - led by Joan Conaway, Ph.D., and Ron Conaway, Ph.D., Investigators - has published findings that shed light on the role of the much-studied transcription factor YY1 in gene expression.

Breast epithelial cells serve as a barrier against cancer

Sheets of highly organized epithelial cells line all the cavities and free surfaces of the body, forming barriers that control the movement of liquids and cells in the body organs.

Brain function is even more impaired in cirrhotic than non-cirrhotic alcoholics

Sustained exposure to alcohol can cause scarring and dysfunction of the liver, referred to as cirrhosis.

World's oldest bacteria

All cells decompose with time. But some cells are better than others to postpone the decomposing and thus delay ageing and eventually death. And there are even organisms that are capable of regenerating and thereby repair damaged cells.

Leading experts meet to help advance motor neurone research

World renowned experts on motor neurone disease will share their work at an international symposium hosted by the University of Edinburgh tomorrow (WED) to enable greater understanding of the condition.

Scientists reveal the actions of a key player in colorectal cancer

Colorectal cancer is one of the most prevalent cancers in the Western world. The tumor starts off as a polyp but then turns into an invasive and violent cancer, which often spreads to the liver.

Australian researchers discover a 'novel molecular dictator with a conscience'

University of New South Wales (UNSW) researchers have uncovered an important naturally occurring mechanism in the body where "bad" cells that cause blockages in our blood vessels are kept under strict growth control, while "good" cells that keep our blood vessels free of clots and growths are left unaffected.

Novel approach used to uncover genetic components of aging

People who live to 100 or more are known to have just as many - and sometimes even more - harmful gene variants compared with younger people.

Smoking turns on genes

Smoking tobacco is no longer considered sexy, but it may prove a permanent turn on for some genes.
