Genetically engineered herpes simplex virus keeps arteries free-flowing

A genetically engineered herpes simplex virus, primarily known for causing cold sores, may help keep arteries "free-flowing" in the weeks following angioplasty or stent placement for patients, according to research published early in the online edition of PNAS (Proceedings of the National Academy of Sciences of the United States of America).

Scientists discover protein instrumental to brain development and repair

Scientists at Children's National Medical Center have demonstrated conclusively that a specific protein and its signaling activity are instrumental in myelination and remyelination, processes essential to the creation and repair of the brain's white matter.

Central command system for pulmonary hypertension discovered

Researchers at the University of Alberta have identified a "central command system" for pulmonary hypertension, a disease that currently has no cure and kills thousands each year.

Increase in prescription drug cost sharing associated with lower rates of drug treatment, adherence

A review of previous studies indicates that an increase in prescription drug cost sharing is associated with a decrease in drug spending and use of pharmacies; and for some chronic conditions, higher cost sharing is associated with greater use of expensive medical services, according to an article in the July 4 issue of JAMA: The Journal of the American Medical Association.

Genetic mutation that may alter response to cancer therapeutics found

Researchers from Eli Lilly & Company and the Phoenix-based Translational Genomics Research Institute (TGen) today announced finding a novel recurring mutation of the gene AKT1 in breast, colorectal and ovarian cancers.

Bayer and Onyx submit supplemental NDA for Nexavar

Bayer HealthCare Pharmaceuticals and Onyx Pharmaceuticals have announced that a Supplemental New Drug Application (sNDA) for Nexavar (sorafenib) tablets has been submitted to the U.S. Food and Drug Administration (FDA) for the treatment of patients with hepatocellular carcinoma (HCC), the most common form of liver cancer. Nexavar is currently approved in more than 50 countries for the treatment of advanced kidney cancer.

New cancer drug target

Research led by scientists at Weill Cornell Medical College has uncovered two new potential points of vulnerability on a key cancer-promoting protein, called XIAP.

Morning sickness may indicate lower risk of breast cancer

It may not seem so at the time, but women who suffer through morning sickness during their pregnancies actually may be fortunate.

Why NSAIDs damage the tissue that lines the gastrointestinal tract

New versions of drugs like buffered aspirin and Vioxx could produce fewer harmful side effects thanks to research being done at Kansas State University's College of Veterinary Medicine.

Novel cellular mechanism that may guide cell movement and possibly cancer cell invasion

Scientists have long thought that microtubules, part of the microscopic scaffolding that the cell uses to move things around in order to hold its shape and divide, originated from a tiny structure near the nucleus, called the centrosome.

Discovery of IKBKE gene linked to breast cancer

Using a novel three-part screening process, scientists at Dana-Farber Cancer Institute have identified a gene that is made inappropriately in about a third of all breast cancers.

The unexpected connection of two gene regulation mechanisms points to new ways for the fight against leukemia

When the activity of individual genes it is longer required, there are two main mechanisms responsible for the “switching off”, mainly DNA methylation and the Polycomb protein complex. Sometimes, these mechanisms lose their efficiency and some of the genes that should be "switched off" remain active.

Cholesterol causes changes in gene expression

Experts from the University of Granada carried out research on atherosclerosis from its earliest stages to discover the origin of atheromatous plaques, fatty deposits gradually and irregularly formed in the main arteries, causing the narrowing of the blood vessel.

A single cancer stem cell is sufficient to initiate and maintain a malignant tumor

At the heart of most, if not all cancers, lie a handful of wayward stem cells that feed the ever growing tumor mass, but their scarcity make it difficult for scientists to study them. Now, times of plenty may lie ahead as a breast cancer cell line , established long ago , turned out to behave a lot like cancer stem cells.

New contributor to aggressive cancers

Mutations in the cell adhesion molecule known as integrin alpha 7 (integrin 7) lead to unchecked tumor cell proliferation and a significantly higher incidence in cancer spread, or metastasis, in several cancer cell lines, report researchers at the University of Pittsburgh School of Medicine in a study published in the Journal of the National Cancer Institute.

miRNAs shown to be a critical force behind the anti-proliferation potential of p53

Cold Spring Harbor Laboratory (CSHL) researchers led by Lin He, Xingyue He, and Professor and Howard Hughes Medical Investigator (HHMI) Greg Hannon have identified a family of micro RNAs (miRNAs) that enable a critical tumor suppressor network, called the p53 pathway, to fight cancer growth.
