Researchers visualize how cells coordinate their movements

Using novel imaging, labeling, and data-analysis techniques, scientists from the California Institute of Technology (Caltech) have been able to visualize, for the first time, large numbers of cells moving en masse during some of the earliest stages of embryonic development.

Protein could prevent blocked arteries

For the first time, researchers have found that a modified form of a naturally occurring protein, N-cadherin, could prevent blocked arteries. Blocked arteries are a major cause of heart attacks and strokes.

When less is more: Brief inhibition of cancer target is effective and less toxic

New research shows that the delicate balance between maximum clinical impact and toxicity may not be quite as fragile as scientists had previously believed.

Statins do not interfere with Rituximab treatment for lymphomas

Statins, drugs widely prescribed to lower cholesterol, do not interfere with a commonly used medication to treat lymphomas, according to a Mayo Clinic study presented at the 50th Annual Meeting of the American Society of Hematology in San Francisco.

Researchers study virus with unusual properties

A team of researchers from Penn State University and the University of Chicago has uncovered clues that may explain how and why a particular virus, called N4, injects an unusual substance -- an RNA polymerase protein -- into an E. coli bacterial cell.

Researchers discover why Gleevec-type drugs control, but do not eradicate leukemia

Oregon Health & Science University Knight Cancer Institute researchers are closer to understanding why certain chronic myeloid leukemia mutations are not stopped by the revolutionary targeted cancer pill, Gleevec, or similar therapies in that drug family.

Levels of insulin-related proteins indicate risk of death in some colorectal cancer patients

A pair of proteins may help explain why people with surgically removed colorectal cancer and who are overweight, physically inactive, and follow a Western-pattern diet may have an increased risk of dying of the disease or other causes, Dana-Farber Cancer Institute scientists report in a new study.

Nuts and Mediterranean diet appear to help metabolic syndrome

A traditional Mediterranean diet with an additional daily serving of mixed nuts appears to be useful for managing some metabolic abnormalities in older adults at high risk for heart disease, according to a report in the December 8/22 issue of Archives of Internal Medicine.

Mathematical model shows how organelles function within cells

Cells are filled with membrane-bound organelles like the nucleus, mitochondria and endoplasmic reticula.

Lenalidomide safe for elderly patients with chronic lymphocytic leukemia

The oral medication lenalidomide is safe and well-tolerated for elderly patients with chronic lymphocytic leukemia, a group without a well-defined frontline therapy for their disease, researchers from The University of Texas M. D. Anderson Cancer Center reported today at the 50th annual meeting of the American Society of Hematology.

Kiadis Pharma receives two orphan drug designations for Reviroc

Kiadis Pharma has announced that the U.S. Food and Drug Administration (FDA) has granted its product Reviroc Orphan Drug Designations (ODD) for the treatment of two types of Non-Hodgkin Lymphoma (NHL).

C. elegans worms may hold key to new treatments for obesity in humans

A previously unknown mutation discovered in a common roundworm holds the promise of new treatments for obesity in humans, McGill University researchers say.

Light cigarettes may be more toxic than traditional cigarettes

Typically, tobacco companies market harm-reduction cigarettes as being safer than traditional "full-flavored" brands, leading many smokers to conclude that the use of harm-reduction brands lowers their exposure to toxicants.

Genetic signature may lead to better treatments for pediatric liver cancers

Scientists have identified a genetic signature that is remarkably effective at predicting the prognosis of an aggressive liver cancer in children.

Discovery of protein that may cause breast cancer to spread

In an important finding published online in Developmental Cell , researchers at Albert Einstein College of Medicine of Yeshiva University, along with collaborators at Massachusetts Institute of Technology, have identified a protein likely responsible for causing breast cancer to spread.

Trial shows safety of pre-transplant expansion of umbilical cord blood stem cells

Taking blood stem cells collected from an umbilical cord into the lab and expanding their number before transplanting them to replace a patient's blood supply is as safe as a standard cord blood transplant, researchers reported at the 50th Annual Meeting of the American Society of Hematology.

Biologists spy close-up view of poliovirus linked to host cell receptor

Researchers from Purdue and Stony Brook universities have determined the precise atomic-scale structure of the poliovirus attached to key receptor molecules in human host cells and also have taken a vital snapshot of processes leading to infection.

An Achilles heel in cancer cells

A protein that shields tumor cells from cell death and exerts resistance to chemotherapy has an Achilles heel, a vulnerability that can be exploited to target and kill the very tumor cells it usually protects, researchers from the University of Illinois at Chicago show in a new study published in the Dec. 9 issue of Cancer Cell.

Alternative splicing proteins prompt heart development

Just as the emotions it represents are dynamic, the heart's development requires dynamic shifts in proteins that prompt alternative spicing, a mechanism that allows a given gene to program the cell to make several proteins, said a group of researchers at Baylor College of Medicine in a report that appears online in the journal Proceedings of the National Academy of Sciences.
