Stem cells' repair skills could be link to cancer

Johns Hopkins researchers say there is growing evidence that stem cells gone awry in their efforts to repair tissue damage could help explain why long-term irritation, such as from alcohol or heartburn, can create a breeding ground for certain cancers.

Discovery of gene mutation in fruit flies that alters sensitivity to crack cocaine

Researchers at the University of California, San Francisco (UCSF) and New York University have discovered a gene mutation in fruit flies that alters sensitivity to crack cocaine and also regulates their internal body clock.

FDA approves Tarceva (erlotinib)

OSI Pharmaceuticals and Genentech have announced that the U.S. Food and Drug Administration (FDA) has approved, after priority review, Tarceva (erlotinib) for the treatment of patients with locally advanced or metastatic non-small cell lung cancer (NSCLC) after failure of at least one prior chemotherapy regimen.

Brain imaging shows differences in people at risk for Alzheimer's

Using brain imaging, researchers at Columbia University Medical Center (CUMC) have found clear differences in brain function between healthy people who carry a genetic risk factor for Alzheimer's disease and those who lack the factor.

Overexpression of a protein called Down Syndrome Critical Region 1 (DSCR-1) reduces tumor growth

Scientists have found that overexpression of a protein called Down Syndrome Critical Region 1 (DSCR-1) blocks the formation of new blood vessels and thus reduces tumor growth. Therapeutics based on this finding may potentially lead to new cancer treatments.

Researchers find mutations in a multifunctional protein cause Parkinsonism

A team of researchers at Mayo Clinic in Jacksonville, Fla. and colleagues in Canada and Germany have discovered a gene and six mutations of it that cause symptoms associated with Parkinson's disease and other neurodegenerative disorders.

New genetic test has proven useful as a prognostic tool for ovarian cancer

The identification of a gene expression profile using microarray technology may help clinicians better determine the prognosis of patients with advanced stage ovarian cancer and may eventually help provide targeted therapies for this hard-to-treat disease, according to a study led by investigators at Beth Israel Deaconess Medical Center (BIDMC).

Understanding the signals that delay the spread of follicular lymphoma could provide new therapeutic targets

Scientists at the National Cancer Institute (NCI), have created a model that predicts the survival of follicular lymphoma patients based on the molecular characteristics of their tumors at diagnosis.

70% of cases of spina bifida are preventable by folic-acid supplementation

A seminar in this week’s issue of THE LANCET discusses the causes, symptoms, and treatments relating to spina bifida, and reinforces an important public-health message for women about to become pregnant

Not all congestion-producing chronic rhinosinusitis infections are the same

Rather, this problem that afflicts some 30 million Americans annually has four severity classifications that could help guide treatment today and help find better treatments in the future, says the lead author on the study published in the November issue of The Laryngoscope.

Gene protects against environmental pollutants and pulmonary emphysema

Researchers at the Johns Hopkins Bloomberg School of Public Health and other institutions have identified a “master gene” in mice that controls the action of 50 other genes whose products protect the lungs against environmental pollutants.

Researchers find effective treatment for Unusual Fever Syndrome caused by cold exposure

Remember when Grandma used to say, "don’t go out in the cold; you’ll get sick”? It turns out that she was right for a small number of people who have a condition called familial cold autoinflammatory syndrome (FCAS)

Troponin genes offer new insights to familial heart failure

Mutations in the troponin protein complex may be useful for predicting the course of heart failure due to dilated cardiomyopathy and also for guiding treatment and research, according to a new study in the Nov. 16, 2004 issue of the Journal of the American College of Cardiology.
