Protein on the surface of platelets plays a key role in cancer-induced platelet aggregation

Scientists have provided new details about how cancer cells spread by surrounding themselves with platelets – the blood cells needed for blood clotting.

Researchers chart the level of gene expression in melanoma cell lines

Other than visually inspecting the disease, doctors have no genetic blueprint to classify melanomas, a lethal form of skin cancer.

Improving diagnosis of pancreatic cancer

In the August issue of Molecular & Cellular Proteomics, scientists provide the first large-scale identification of proteins that are overexpressed in chronic pancreatitis, an inflammatory condition of the pancreas that shares many features with pancreatic cancer.

New anti-cancer drug made from corn lillies kills brain tumor stem cells

A drug that shuts down a critical cell-signaling pathway in the most common and aggressive type of adult brain cancer successfully kills cancer stem cells thought to fuel tumor growth and help cancers evade drug and radiation therapy, a Johns Hopkins study shows.

Discovery may lead to new class of diabetes drugs

A multidisciplinary team led by researchers at the University of California, San Diego has determined the structure of a protein found in cells that shows potential as a target for the development of new drugs to treat diabetes.

Contact disorder makes cancer cells mobile

The loss of the protein VMP1 in cancer cells increases their tendency to detach from the initial tumor - the first step towards metastasis.

Binghamton University researchers investigate evolving malaria resistance

Funded by a $1.5 million grant from the National Institutes of Health, scientists at Binghamton University, State University of New York, hope to understand how the malaria parasite Plasmodium falciparum evolved resistance to the once-effective medication chloroquine.

New method for fighting skin wrinkles

A new method for fighting skin wrinkles has been developed at the Hebrew University Faculty of Agriculture, Food and Environmental Quality Sciences.

Research looks at hepatitis C recovery

More than 3% of world population is infected with hepatitis C virus (HCV). The outcome of HCV infections is either self recovery or chronic hepatitis, and many of the chronic infections will develop into liver cirrhosis or liver cancer.

Researchers unlock mystery of a third olfactory system

Researchers at the University of Maryland School of Medicine have found a "nose within the nose," a unique olfactory system within the noses of mice that is able to "smell" hormones involved in regulating water and salt balance in the body.

Researchers dispute immortal strand hypothesis

How do adult stem cells protect themselves from accumulating genetic mutations that can lead to cancer?

Third factor identified in obesity-induced Type 2 diabetes

In cases of Type 2 diabetes, the body's cells fail to appropriately regulate blood glucose levels.

Researchers discover nature uses a recurring molecular strategy to defend against infection

With infections increasingly resistant to even the most modern antibiotics, researchers at the Los Angeles Biomedical Research Institute at Harbor-UCLA Medical Center (LA BioMed) report in the September issue of Nature Reviews Microbiology on new clues they have uncovered in immune system molecules that defend against infection.

Report on access to cancer drugs across Europe flawed

A leading epidemiologist has attacked Swedish research that looked at inequalities in patients' access to cancer drugs across Europe and the world.

Big leap in genomic screening of blood vessels from patient tissue

Scientists have developed a new method of capturing a complete genome-wide screening of blood vessel cells in their actual disease state, advancing the potential for genetic research on the tissue responsible for delivering nourishment that can accelerate the growth of both a cancer tumor or wound healing.

Influence of sex and handedness on brain is similar in capuchin monkeys and humans

Capuchin monkeys are playful, inquisitive primates known for their manual dexterity, complex social behavior, and cognitive abilities.

Discovery of key link that causes malarial infection in both humans and mosquitoes

As summer temperatures cool in the United States, fewer mosquitoes whir around our tiki torches.

Autophagy-induced signals are essential for normal development

A cannibalistic process called autophagy spurs dying embryonic stem cells to send "eat me" and "come get me" signals to have their corpses purged, a last gasp that paves the way for normal mammalian development, UT Southwestern Medical Center researchers have found.

Researchers discover what makes lymphomas tick

University of Pennsylvania researchers and their colleagues at the Wistar Institute and University of Oxford have discovered the molecular process by which the PAX5 protein, necessary for lymphocyte development, promotes the growth of common lymphomas, thereby unveiling a potential new target in the fight against cancer.
