Biomarker News and Research

RSS

A biomarker is a biological molecule found in blood, other body fluids, or tissues that is a sign of a normal or abnormal process, or of a condition or disease. A biomarker may be used to see how well the body responds to a treatment for a disease or condition. Also called molecular marker and signature molecule.

Cell response to stress signals predicts tumors in women with common pre-breast cancer

A specific biological response to cellular stress may predict the likelihood of future tumor formation of the most common, non-invasive form of pre-malignant breast cancer-- ductal carcinoma in situ, or DCIS.

Molecular markers predict risk for invasive breast cancer years before the tumor develops

A team of scientists from the University of California San Francisco has identified distinct molecular markers that predict whether or not a woman is likely to develop subsequent invasive cancer after initial diagnosis with a noninvasive form of early breast cancer.

Osteopontin-c is a good biomarker of breast cancer.

Researchers have identified a molecule that may be more accurate than existing biological signposts used to predict which breast cancers will develop into advanced forms of the disease.

Vitamin A derivative associated with reduced growth in some lung cells

Treatment with a derivative of vitamin A called retinoic acid was associated with reduced lung cell growth in a group of former heavy smokers, according to a study published online October 30 in the Journal of the National Cancer Institute.

New brain marker predicts cognitive decline and the development of Alzheimer's disease

Duke University Medical Center researchers have used imaging technology to identify a new marker that may help identify those at greatest risk for cognitive decline and the development of Alzheimer's disease.

Children would need different medical care in wake of dirty bomb

If terrorists were to attack with a dirty bomb, medical authorities should be prepared to treat children differently than adults because their developing bodies would absorb and respond to the radiation exposure in distinct ways, according to a new study from the University of Rochester Medical Center.

Possible biomarker for colon cancer in people under 50

An abnormality of chromosomes long associated with diseases of aging has, for the first time, been linked to colon cancer in people 50 years old and younger, an age group usually considered young for this disease.

Blood markers can help choose best dose for antiangiogenic drugs

Scientists at Sunnybrook have new information that may help to improve the use of anti-cancer drugs designed to block the growth of new blood vessels in tumors, a process called angiogenesis that is critical to tumor growth.

Human decision-making linked to an individuals' need to maintain a homeostatic balance

A researcher at the University of California, San Diego (UCSD) School of Medicine suggests that psychiatrists may need to approach the treatment of psychiatric patients from a new direction - by understanding that such individuals' behavior and decision-making are based on an attempt to reach an inner equilibrium.

Severely restricting calories leads to a longer life

New research now has shown for the first time that such a diet also can maintain physical fitness into advanced age, slowing the seemingly inevitable progression to physical disability and loss of independence.

Potent inhibitor of Kinesin CENP-E demonstrates tumor cell inhibition

A first-in-class, targeted investigational therapy specifically designed to inhibit a single protein that functions only during cell division shows potent activity in a broad range of cancer cell lines, say researchers from GlaxoSmithKline.

Advances in drug screening

With the discovery of suitable molecular targets - cellular molecules along pathways crucial for sustaining the life of cancer cells - comes the perplexing dilemma of where to find the next therapeutics that will bind to and disable those targets.

Study explains why physical activity is beneficial in preventing heart attack and stroke

It is well known that physical activity can improve cardiovascular health. But it's the impact exercise has on specific known risk factors that accounts for about 60 percent of that improvement, researchers reported in Circulation: Journal of the American Heart Association.

Health Discovery receives notice of allowance of U.S. patent application covering kernel selection methods

Health Discovery Corporation has announced that the U.S. Patent and Trademark Office has issued a notice of allowance of HDC's patent application covering methods for selection of kernels, i.e., functions or algorithms that are used to transform input data into a different configuration, known as "feature space", which allows for easier recognition of patterns within the data.

New insight into Herceptin resistance in breast cancer

A new study provides important insight into the mechanisms involved in resistance to treatment of breast cancer patients with trastuzumab (Herceptin). The research, published by Cell Press in the October issue of the journal Cancer Cell , identifies markers that may help to identify patients who are unlikely to respond to trastuzumab treatment and provides a potential strategy for treating these patients.
