Comprehensive assessment of long-term effects of reducing intake of energy

Overweight people who lose a moderate amount of weight get an immediate benefit in the form of better heart health, according to a study conducted at Washington University School of Medicine in St. Louis.

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.
