Flightless molecule may help control spread of cancer from one tissue to another

Thanks to the "flightless" molecule, the spread of cancer from one tissue to another may one day be grounded. In a new report published in the August 2012 print issue of The FASEB Journal, laboratory experiments show that "flightless" (named after its effects on fruit flies) increases the "stickiness" that causes cells, including cancer cells, to attach to underlying tissue, which in turn, slows their movement throughout the body.

New computational method to help organize scientific data

Researchers from Mount Sinai School of Medicine have developed a new computational method that will help organize scientific data, making it easier for scientists to identify and prioritize genes, drug targets, and connections between drugs. By mining large datasets more simply and efficiently, researchers will be able to better understand gene-gene, protein-protein, and drug/side-effect interactions.

New algorithm can help scientists predict gene and drug interactions

Researchers from Mount Sinai School of Medicine have developed a new computational method that will make it easier for scientists to identify and prioritize genes, drug targets, and strategies for repositioning drugs that are already on the market. By mining large datasets more simply and efficiently, researchers will be able to better understand gene-gene, protein-protein, and drug/side-effect interactions. The new algorithm will also help scientists identify fellow researchers with whom they can collaborate.

Scientists uncover how internal mechanisms in nerve cells wire the brain

Scientists at the University of Manchester have uncovered how the internal mechanisms in nerve cells wire the brain. The findings open up new avenues in the investigation of neurodegenerative diseases by analysing the cellular processes underlying these conditions.

Cadherin-catenin-actin structure exerts force inside and between cells in living tissues

If you place certain types of living cells on a microscope slide, the cells will inch across the glass, find their neighbors, and assemble themselves into a simple, if primitive tissue. A new study at Stanford University may help explain this phenomenon, and then some, about the mechanical structure and behavior of complex living organisms.

UMMS scientists identify new genetic mutation that causes familial ALS

A new genetic mutation that causes familial amyotrophic lateral sclerosis (ALS), a fatal neurological disorder also known as Lou Gehrig's Disease, has been identified by a team of scientists led by researchers at the University of Massachusetts Medical School (UMMS).

Human immune response: TCD scientists make breakthrough which could lead to new drug therapies

A team of researchers at Trinity College Dublin’s School of Medicine has gained new insights into a protein in the human immune system that plays a key role in the protective response to infection and inflammation. The research findings have just been published in the internationally renowned peer-reviewed Journal of Biological Chemistry.

Caspase-11 enzyme plays an important role in Legionella infection

New research shows that an enzyme that has long been considered relatively useless to the immune response instead has an important role in setting up immune cells to kill infection-causing bacteria.

Researchers discover location and effect of abnormal heart proteins

University of Guelph researchers have found the location and effect of abnormal heart proteins that can cause cardiac failure, a discovery that points to potential new ways to treat the most costly health problem in the world.

Scientists identify how Clec9A protein recognises foreign invaders

The discovery of how a vital immune cell recognises dead and damaged body cells could modernise vaccine technology by 'tricking' cells into launching an immune response, leading to next-generation vaccines that are more specific, more effective and have fewer side-effects.

Multimarker molecular stool test for colon cancer unaffected by medication, lifestyle factors

Research on an investigational DNA methylation test for colorectal cancer demonstrated that the only clinical variable that influenced test results was age, according to results presented at the AACR Annual Meeting 2012, held here March 31 - April 4.

Starvation during childhood may increase risk of heart complications

Russians born during the Leningrad Siege in World War II, which was responsible for some of the greatest losses of civilian life in history, are giving scientists new strategies to identify people who experienced intrauterine growth restriction (IUGR) and starvation during childhood at greatest risk of developing long term heart complications.

New treatment approach halts spread of cancer cells into normal brain tissue

Treating invasive brain tumors with a combination of chemotherapy and radiation has improved clinical outcomes, but few patients survive longer than two years after diagnosis. The effectiveness of the treatment is limited by the tumor's aggressive invasion of healthy brain tissue, which restricts chemotherapy access to the cancer cells and complicates surgical removal of the tumor.

Researchers design new treatment approach for invasive brain tumors

Researchers from Emory and the Georgia Institute of Technology have designed a new treatment approach that appears to halt the spread of cancer cells into normal brain tissue in animal models.

Researchers confirm how food poisoning bacteria hijack cell's sense of direction

Working in the emerging field of systems biology, UT Southwestern Medical Center researchers mathematically predicted how bacteria that cause food poisoning hijack a cell's sense of direction and then confirmed those predictions in living cells.

ACTB and ACTG1 actin genes cause Baraitser-Winter syndrome

Scientists from Seattle Children's Research Institute and the University of Washington, in collaboration with the Genomic Disorders Group Nijmegen in the Netherlands, have identified two new genes that cause Baraitser-Winter syndrome, a rare brain malformation that is characterized by droopy eyelids and intellectual disabilities.

Nicotine can contribute to atherosclerosis

Cigarette smoke has long been considered the main risk factor for heart disease. But new research from Brown University in Providence, R.I., shows that nicotine itself, a component of cigarette smoke, can contribute to the disease process by changing cell structure in a way that promotes migration and invasion of the smooth muscle cells that line blood vessels.

New link between beta-arrestin and short-term memory

Biomedical scientists at the University of California, Riverside have identified a new link between a protein called beta-arrestin and short-term memory that could open new doors for the therapeutic treatment of neurological disorders, particularly Alzheimer's disease.

BPS Annual Meeting to be held Feb. 25 - 29 in San Diego

The latest news and discoveries in medicine, physics, environmental science, and interdisciplinary fields will be featured at the 56th Annual Meeting of the Biophysical Society (BPS), held Feb. 25 - Feb. 29, 2012, at the San Diego Convention Center in San Diego, Calif. With more than 4,000 poster presentations, 200 exhibits, 20 symposia, and 6,000 research scientists in attendance each year, the BPS Annual Meeting is the largest meeting of biophysicists in the world.

Researchers discover how SHP-2 genetic defect may result in heart malformation

UNC researchers have discovered how the genetic defect underlying one of the most common congenital heart diseases keeps the critical organ from developing properly. According to the new research, mutations in a gene called SHP-2 distort the shape of cardiac muscle cells so they are unable to form a fully functioning heart.
