No link found between hair dyes and cancers

The growing worldwide concern about a possible link between hair dyes and some forms of cancer, which was further fuelled by one recent study showing an apparent positive relationship, prompted a European Commission safety panel to call for an urgent review.

Findings demonstrate that abnormal expression of the BCL6 gene causes lymphoma

This advancement has the potential to significantly speed the development of new, improved therapies for diffuse large B cell lymphoma (DLBCL), the most common type of human B cell lymphoma. Human B cell lymphomas cause 85 percent of non-Hodgkin’s lymphomas, the sixth leading cause of cancer deaths in the United States.

Secrets of how the brain is wired for sex revealed

There are two brain structures that a mouse just can't do without when it comes to hooking up with the mate of its dreams--and trying to stay off the lunch menu of the neighborhood cat. These are the amygdala, which is involved in the initial response to cues that signal love or war, and the hypothalamus, which coordinates the innate reproductive or defensive behaviors triggered by these cues.

WHO says world must prepare for bird flu pandemic

Reports of disturbing changes to the H5N1 virus circulating in Asia is causing great concern and has prompted the World Health Organization (WHO) to urge countries to prepare for a influenza pandemic.

Discovery may lead to new drugs to treat cancer, control fertility

A recent discovery in cellular biology may allow scientists to enhance organ regeneration by stem cells, prevent the progression of cancer, and control fertility.

Researchers find first gene for inherited testicular cancer in mice

In this week's journal Nature, researchers report finding the first gene responsible for inherited susceptibility of testicular cancer in mice. The Ter mutation occurs in a gene called dead end, which is involved in normal testicular development and which may play a role in inherited forms of a testicular cancer occurring in infants.

Disease progression model of pancreatic cancer developed

Building on previous work, researchers at the University of Pennsylvania School of Medicine have developed an animal model of pancreatic cancer that closely mimics disease progression in humans. From this, they hope to develop new treatments for this deadly disease.

Human cells can silence an essential part of HIV's genetic make-up

For the first time, scientists have shown that humans use an immune defense process common in plants and invertebrates to battle a virus.

EraGen Biosciences and Bayer announce agreements for new cystic fibrosis (CF) assay

EraGen Biosciences, a rapidly growing molecular diagnostics company and Bayer HealthCare LLC, Diagnostics Division, announced today that EraGen has licensed its patented MultiCode-PLx® System to Bayer HealthCare in an exclusive worldwide agreement for Cystic Fibrosis.

Researchers create the first mouse model that develops a lymphoma the same way that humans do

This advancement has the potential to significantly speed the development of new, improved therapies for diffuse large B cell lymphoma (DLBCL), the most common type of human B cell lymphoma. Human B cell lymphomas cause 85 percent of non-Hodgkin's lymphomas, the sixth leading cause of cancer deaths in the United States.

Antibody combined with cancer drug shows promise against breast tumors

An antibody that targets the blood vessels nourishing tumors significantly reduced breast cancer formation and growth in mice when combined with a current cancer drug, according to researchers at UT Southwestern Medical Center.

Drugs that block the enzyme Odc prevent the onset of cancers

The drug DFMO prevents cancer in laboratory models of lymphoma but fails to kill existing cancerous cells that have lost the ability to self-destruct, according to investigators at St. Jude Children's Research Hospital.

Combined MRI and mammography more effective at detecting breast cancer in high risk women

Annual screening, using magnetic resonance imaging (MRI) and X-ray mammography, is the best way to detect breast cancer in women that have a high genetic risk of the disease, according to a study published online by The Lancet.

Research findings help predict risk of blood clots in women receiving tamoxifen therapy for breast cancer

New research findings may help physicians determine which women have an increased risk of blood clots when taking tamoxifen for the management of breast cancer, a team led by Dana-Farber Cancer Institute investigators will report at the American Society of Clinical Oncology's annual meeting.

Humans more prone to cancer than chimpanzees

Chimpanzees and humans share a common ancestor, and even today 99 percent of the two species' DNA is identical. But since the paths of man and chimp diverged 5 million years ago, that one percent of genetic difference appears to have changed humans in an unexpected way: It could have made people more prone to cancer.

As science gets wiser, so do the bugs

As science gets wiser, so do the bugs. The rates of drug-resistant bacteria infecting patients in the community and in the hospital have been increasing steadily in recent years, according to two new studies in the June 15 issue of Clinical Infectious Diseases.

Chronic kidney disease linked to a single gene mutation

New research in the US has found that a mutation in a single gene causes a form of chronic kidney disease.

Mosaic Analysis with Double Markers (MADM) - A powerful new tool to study diseases and genetics

A powerful laboratory technique used by fruit fly geneticists for more than a decade is now available to scientists studying genes and diseases in mice.

Scientists extend the lifespan of mice

Scientists at the University of Washington and their colleagues at other research centers have found a way to significantly extend the lifespan of mice while reducing the impact of the aging process. Their study, which will be published online by the journal Science on May 5, lends more credence to the free-radical theory of aging.
