Gene therapy can reduce long-term drinking among rodents

Just as the risk of developing alcoholism is strongly influenced by genetic factors, mutations in gene coding - such as the aldehyde dehydrogenase (ALDH2*2) allele - also appear to protect against the risk.

Down syndrome points to a new way of repressing cancer growth

Researchers at Johns Hopkins and Ohio State University have found that the number of copies of a particular gene can affect the severity of colon cancer in a mouse model. Publishing in the Jan. 3 issue of Nature, the research team describes how trisomy 21, or Down syndrome in humans, can repress tumor growth.

Down's syndrome gene protects against cancer

Researchers in the United States say the chromosomal abnormality that affects people with Down's syndrome also protects them against cancer.

Scientists find missing evolutionary link using tiny fungus crystal

The crystal structure of a molecule from a primitive fungus has served as a time machine to show researchers more about the evolution of life from the simple to the complex.

Researchers seek to make cavity-causing bacteria self-destruct

Bacteria that eat sugar and release cavity-causing acid onto teeth may soon be made dramatically more vulnerable to their own acid.

Artificial viral shells for pinpoint drug delivery

Researchers at the Technion-Israel Institute of Technology and The Scripps Research Institute in California are designing an artificial viral shell as a valuable nano-container for pinpoint drug delivery, molecular computing components, and a host of other applications.

Gene variation increases risk of liver tumor in patients with cirrhosis

A particular gene variation appears to significantly increase the risk that individuals with cirrhosis of the liver will go on to develop hepatocellular carcinoma (HCC), a liver tumor that is the third leading cause of cancer death.

Ashkenazi ovarian cancer patients with BRCA mutations live longer than those with normal gene

Israeli investigators have found that Ashkenazi Jewish women with ovarian cancer who have mutations in the BRCA1 or BRCA2 genes lived significantly longer than Ashkenazi Jewish ovarian cancer patients without these mutations.

Two genes are important key to regulating immune response

A research team at Weill Cornell Medical College in New York City has identified two genes that may be crucial to the production of an immune system cytokine called interleukin-10 (IL-10)

Sea-cucumber protein may provide methods of preventing the transmission of malaria

Scientists have genetically engineered a mosquito to release a sea-cucumber protein into its gut which impairs the development of malaria parasites, according to research out today (21 December) in PLoS Pathogens.

Overeating and obesity triggered by lack of brain-derived neurotrophic factor

According to the Centers for Disease Control and Prevention, close to one-third of the population in the United States is obese and another third is overweight.

Mutations in a protein called dynein may cause inherited neuropathy

Mutations in a protein called dynein, required for the proper functioning of sensory nerve cells, can cause defects in mice that may provide crucial clues leading to better treatments for a human nerve disorder known as peripheral neuropathy, which affects about three percent of all those over age 60.

Model developed that predicts molecular response of living cells to genetic or environmental change

Scientists at the Institute for Systems Biology (ISB), in collaboration with researchers from New York University (NYU), have developed a model which rapidly characterizes and accurately predicts the molecular-level, mechanistic response of a free-living cell to genetic and environmental changes.

New information about how normal cells and cancer cells survive under stress

Scientists report that an evolutionarily conserved transcription factor may have both positive and negative effects on the growth of tumors, depending on whether or not the tumor cells have enough oxygen.

New immune system discovery will help fight hay fever and other allergies

A mechanism which can lead to hay fever and other allergic reactions, by preventing the immune system from regulating itself properly, has been discovered by scientists.

Copy number variation may stem from replication misstep

Genome rearrangements, resulting in variations in the numbers of copies of genes, occur when the cellular process that copies DNA during cell division stalls and then switches to a different genetic "template," said researchers at Baylor College of Medicine in Houston in a report that appears today in the journal Cell.
