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.

PreMD files provisional patent application for new method of quantifying cancer biomarkers

Predictive medicine company PreMD Inc. has announced that it has filed a provisional patent application that describes a new simplified method of quantifying immunohistochemical staining of biomarkers. The provisional patent application was filed with the United States Patent and Trademark office.

Married men more likely to be screened for prostate cancer

Although the link between early screening and prostate cancer survival is well established, men are less likely to go for early screening unless they have a wife or significant other living with them, according to a study published in Cancer Epidemiology, Biomarkers and Prevention , a journal of the American Association for Cancer Research.

Migraines linked to lower risk of breast cancer

Women who suffer from migraines may take at least some comfort in a recent, first-of-its-kind study that suggests a history of such headaches is associated with a significantly lower risk of breast cancer. Christopher I. Li, M.D., Ph.D., and colleagues at Fred Hutchinson Cancer Research Center report these findings in the November issue of Cancer Epidemiology, Biomarkers and Prevention.

Environmental tobacco smoke linked to behavioral problems in boys with asthma

Boys with asthma who are exposed to environmental tobacco smoke have higher degrees of hyperactivity, aggression, depression and other behavioral problems, according to researchers at Cincinnati Children's Hospital Medical Center.

Researchers study newborns' umbilical cord blood to better understand fetal health risks from smoking mothers

Despite the well-known dangers of first- and secondhand smoke, an estimated ten percent of pregnant women in the U.S. are smokers.

Prototype blood scanner detects even faint indicators of cancer

A team led by Stanford researchers has developed a prototype blood scanner that can find cancer markers in the bloodstream in early stages of the disease, potentially allowing for earlier treatment and dramatically improved chances of survival.

Analysis of tissue biomarkers expressed in ovarian cancer samples

Although ovarian cancer is not the most common gynecologic cancer in women, the disease contributes a substantial burden of mortality in part because symptoms are nonspecific and the disease presents late in its course.

Scientists develop 'barcode chip' to revolutionize diagnostic medical testing

In less than 10 minutes, and using just a pinprick's worth of blood, the chip can measure the concentrations of dozens of proteins, including those that herald the presence of diseases like cancer and heart disease.

Understanding how oxidative stress impairs endothelial progenitor cell function may lead to antioxidant therapy to prevent cardiovascular disease

Although its been over a decade since endothelial progenitor cells or EPCs, cells that circulate in the blood repairing and replacing the cells that line blood vessels, were identified, the field is still evolving. EPCs are now being studied as biomarkers to assess the risk of future cardiovascular disease and as potential agents for vascular regeneration.

Gefitinib just as effective as chemotherapy for lung cancer

Gefitinib, also known as Iressa, the once-promising targeted therapy for the treatment of non-small cell lung cancer, has proven as effective as chemotherapy as a second-line therapy for the disease with far fewer side effects, according to an international Phase III clinical trial, led by researchers at The University of Texas M. D. Anderson Cancer Center.

Carbon nanotubes detect lung cancer markers in the breath

Using an array of nanotube devices, each coated with a different organic material, researchers at the Israel Institute of Technology have developed diagnostic system that may be able to diagnose lung cancer simply by sampling a patient's breath. The results of this study, which was led by Hossam Haick, Ph.D., appear in the journal Nano Letters.
