Insights into cell movement likely to aid immune study, cancer research

Scientists at Washington University School of Medicine in St. Louis have used yeast cells to better understand a collection of proteins associated with the formation of actin networks, which are essential to cell movement.

Differentiation blocked in tumor stem cells

A new comparison of normal stem cells and cancer stem cells reveals that the cancer stem cells are abnormally trapped at an early stage of development.

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.

Breast cancer cells have to learn to walk before they can run

Early-stage breast cancer that has not yet invaded the surrounding tissues may already contain highly motile cells, bringing the tumor one step closer to metastasis, report researchers at the Salk Institute for Biological Studies.

Discovery of molecular signal that helps muscle regenerate and protects it from atrophy

It does not take much to injure a muscle. Sometimes one sudden, inconsiderate movement does the job.

Overexcited neurons not good for cell health

Neurotransmitters have consequences. They initiate events that are critical to a healthy life, giving us the ability to move, to talk, to breathe, to think. But that's if the neurotransmitters are getting it right and sending proper signals downstream to muscle cells, neurons or other cells.

New mechanical insights into wound healing and scar tissue formation

New research published today in the Journal of Cell Biology illuminates the mechanical factors that play a critical role in the differentiation and function of fibroblasts, connective tissue cells that play a role in wound healing and scar tissue formation.

Sunitinib may be associated with cardiac toxicity

Another FDA-approved targeted cancer drug, sunitinib (SutentTM, Pfizer), may be associated with cardiac toxicity, report researchers at Children's Hospital Boston, Dana-Farber Cancer Institute (Boston), and Thomas Jefferson University (Philadelphia).

Great-grandparent of all the cells of the blood identified

Researchers at the Stanford University School of Medicine have isolated a human blood cell that represents the great-grandparent of all the cells of the blood, a finding that could lead to new treatments for blood cancers and other blood diseases.

New model for neurodegeneration

The gradual loss of dopamine neurons is a hallmark of many neurodegenerative diseases - Parkinson's Disease chief among them.

Polybrominated diphenyl ethers used as fire retardants could be harmful

Polybrominated diphenyl ethers (PBDEs), chemicals used as fire retardants, can be found in numerous items in the home, such as the television, computer, toaster and the sofa.

Intestinal parasite Giardia uses an osmotic 'suction cup' to hang on

Known in America chiefly as the bane of hikers, the single-celled intestinal parasite Giardia lamblia is a major cause of diarrheal illness worldwide with estimates of 100 million infections a year.

Inhaled immune system stimulant launches immune response in lungs to wipe out lethal infections

An inhaled immune system stimulant protects mice against lethal pneumococcal pneumonia and other deadly bacterial, viral and fungal infections of the lungs, a research team led by scientists at The University of Texas M. D. Anderson Cancer Center reports at a major scientific meeting.
