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.

Enzyme in the blood that could be a potential marker for heart failure

A team of scientists led by Walter Koch, Ph.D., director of the Center for Translational Medicine in the Department of Medicine in Jefferson Medical College of Thomas Jefferson University in Philadelphia, previously showed that an enzyme called GRK2 or beta-adrenergic kinase (ßARK1) is critically important in heart function.

Gene expression levels may reveal stage of Huntington's disease

A survey of the genome of patients with Huntington's Disease (HD) has identified potential markers of the progression of this devastating neurological disorder.

Analytical tool to help detect cancer

Scientists have long used ultra-fine glass tubes known as capillaries to analyze the chemical makeup of substances. Called capillary electrophoresis, or CE, the method applies high voltage to the capillaries, and by measuring the rate that the various materials move through the capillaries, researchers are able to identify individual compounds.

Activated Stat5 protein in prostate cancer can predict outcome, may help target treatment

Researchers from Lombardi Comprehensive Cancer Center at Georgetown University found that testing for an activated Stat5 protein in prostate tumor tissue effectively predicts which men have a form of prostate cancer that may become more aggressive and life threatening.

Researchers identify protein called EMP-1 that is present in the tumors of patients who fail to respond to treatment with gefitinib

By the time the human genome was mapped, cancer researchers had already begun investigating the proteins that were encoded by these newly identified genes.

Power3 converts provisional patent applications

Power3 Medical Products announced today that it has converted two provisional patent applications by the filing of two utility patent applications with the United States Patent and Trademark Office for the Company's disease specific biomarker discovery and disease specific immuno- diagnostic test designs.

No single PSA level ensures safety from prostate cancer risk

Ian M. Thompson Jr., M.D., professor and chair of urology at the U T Health Science Center, is looking for a better test - or set of tests - to diagnose prostate cancer and to distinguish between cancers that will kill men if left untreated and those that will not threaten health and do not need treatment.

New search method could aid in the discovery of biomarkers for breast cancer

Using a super-efficient method they invented to search for a type of cancer-related change in all genes of a cell, Dana-Farber Cancer Institute researchers have discovered new evidence about how the "microenvironment" of breast cancers helps drive the cancers' growth and migration.

Researchers identify six genes associated with lymphocytic bronchitis - could mean new test, treatments

Researchers at the San Francisco VA Medical Center (SFVAMC) and the University of California, San Francisco (UCSF) have identified six genes associated with lymphocytic bronchitis, which is thought to lead to obliterative bronchitis (OB), the most common cause of long-term failure of transplanted lungs.

Curcumin has potent anticancer powers

Curcumin, a spice commonly used in curries and other south Asian cooking, blocks a key biological pathway needed for development of melanoma and other cancers, say researchers from the University of Texas M. D. Anderson Cancer Center.

Accuracy of PSA screening for detecting prostate cancer

A new study indicates there is no specific PSA value that has both high sensitivity and high specificity for monitoring healthy men for prostate cancer, but rather there is a continuum of prostate cancer risk at all values of PSA, according to a study in the July 6 issue of JAMA: The Journal of the American Medical Association.

New low-cost technology that allows thousands of tumor slices to be screened side-by-side

Scientists at Georgetown University's Lombardi Comprehensive Cancer Center have devised a new low-cost technology that allows thousands of tumor slices to be screened side-by-side, an improvement over current and more expensive methods that can analyze only several hundred tumors at once.

FDA severely limits access to cancer drug Iressa

After Food and Drug Administration (FDA) officials agreed with studies showing lung cancer drug, Iressa, did not help patients live longer, drug company AstraZeneca said it would severely limit access to its drug.

New techniques use mitochondrial DNA as an early indicator for certain types of cancer

A pilot study at the National Institute of Standards and Technology (NIST), in support of the National Cancer Institute's Early Detection Research Network (EDRN), has validated the measurement accuracy of new techniques that use mitochondrial DNA as an early indicator for certain types of cancer.

Claudin-1 regulates cellular transformation and metastatic behavior in colon cancer

Disruption of proteins expressed at the junctures between cells (known as tight junctions) is a hallmark of cancer cell invasion and spread (metastasis).

Inactive gene may explain higher incidence of prostate cancer in African-Americans compared to Caucasians

Among African-Americans with prostate cancer, a tumor-suppressing gene called GSTP1 is inactivated at a rate 3.5 times higher than among Caucasians, according to a study conducted at the San Francisco VA Medical Center (SFVAMC).
