Non-toxic radioactive patch successfully treats skin cancer

A new study shows that a radioactive skin patch can safely and successfully treat basal cell carcinoma, one of the most common types of skin cancers, according to researchers at the SNM's 56th Annual Meeting. The skin patch, which delivers the radioactive phosphorus-32, is nontoxic and could be an excellent alternative to surgery or radiotherapy in cases where carrying out these treatments is difficult.

Discovery in dendritic cell signalling pathways pave way for new therapeutic targets

Scientists from A*STAR's Singapore Immunology Network (SIgN) and the University of Milano-Bicocca, Italy, have discovered another signaling pathway for the activation and apoptosis, or programmed cell death, of dendritic cells. This discovery was published in the advanced online publication of Nature on 15 Jun 2009.

Cancer immunotherapy can use small numbers of ‘stem-like’ immune cells to destroy large tumors in mice

A new approach to stimulating immune cells enhances their anticancer activity, resulting in a powerful anti-tumor response in mice, according to a study by researchers at the National Cancer Institute, a part of the National Institutes of Health. This work represents an important advance in the development of immunotherapy for cancer and appears online June 14, 2009 in Nature Medicine.

Protein regulates movement of mitochondria in brain cells

Scientists have identified a protein in the brain that plays a key role in the function of mitochondria - the part of the cell that supplies energy, supports cellular activity, and potentially wards off threats from disease.The discovery, which was reported today in the Journal of Cell Biology, may shed new light on how the brain recovers from stroke.

Discovery of key gene in deadly inflammatory breast cancer

Aggressive, deadly and often misdiagnosed, inflammatory breast cancer (IBC) is the most lethal form of primary breast cancer, often striking women in their prime and causing death within 18 to 24 months.

Scientists launch Gene Expression Atlas

Today, researchers at the European Molecular Biology Laboratory's European Bioinformatics Institute (EMBL-EBI) launch a new database, the Gene Expression Atlas, which allows scientists to search and compare gene expression data at unprecedented detail and scope. Observing how gene expression varies in different cell types, tissues and under disease conditions can help researchers understand gene function and to develop new drugs and therapies.

Single gene found to control growth of some cancers

Research led by Ashok Aiyar, PhD, Associate Professor of Microbiology at LSU Health Sciences Center New Orleans, showing that a single gene can control growth in cancers related to the Epstein-Barr virus and that existing therapeutics can inactivate it, will be published in the June 12, 2009 online issue of PLoS Pathogens.

Don't stress when the going gets tough - you'll go gray!

A study by Japanese researchers has revealed that a certain kind of stress damages the hair - they say "genotoxic stress" damages DNA by depleting the melanocyte stem cells (MSCs) within hair follicles that are responsible for making the pigment-producing cells.

Waste disposal protein key to cancer tumor suppression in autophagy

"Taking out the trash" takes on a whole new meaning, as investigators at The Cancer Institute of New Jersey (CINJ) and Rutgers, The State University of New Jersey, have discovered that a waste disposal protein is the key to cancer tumor suppression in a process known as autophagy. CINJ is a Center of Excellence of UMDNJ-Robert Wood Johnson Medical School.

Discovery of DNA mutation that occurs at beginning point of T-cell lymphoma

Researchers at the Keck School of Medicine of the University of Southern California (USC) have identified a key mechanism that causes chromosomes within blood cells to break - an occurrence that marks the first step in the development of human lymphoma.

Structure of the HIV protein shell revealed

New research by scientists at The Scripps Research Institute and other institutions provides a close-up look at the cone-shaped shell that is the hallmark of human immunodeficiency virus (HIV), revealing how it is held together - and possible ways to break it apart.

Certain pesticides double the risk of blood disorder

A study involving 678 individuals who apply pesticides, culled from a U.S. Agricultural Health Study of over 50,000 farmers, recently found that exposure to certain pesticides doubles one's risk of developing an abnormal blood condition called MGUS (monoclonal gammopathy of undetermined significance) compared with individuals in the general population.

Estrogen receptor status may modify how a protein that spurs leukemia behaves in the breast

A protein known to play a role in growth of some types of leukemia appears to have a mixed function in breast cancer development, say researchers from the Lombardi Comprehensive Cancer Center at Georgetown University Medical Center (GUMC).

90 per cent of the world's population won't have access to antivirals in pandemic - generic drugs may help though

Almost 90 per cent of the world's population will not have timely access to affordable supplies of vaccines and antiviral agents in the current influenza pandemic, but it is possible that inexpensive generic drugs that are readily available, even in developing countries, could save millions of lives.

Resveratrol shows potential for significant health benefits

The benefits of alcohol are all about moderation. Low to moderate drinking - especially of red wine - appears to reduce all causes of mortality, while too much drinking causes multiple organ damage. A mini-review of recent findings on red wine's polyphenols, particularly one called resveratrol, will be published in the September issue of Alcoholism: Clinical & Experimental Research; the review is also available at Early View.
