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.

Loss of stromal protein major new prognostic factor in patients with breast cancer

Reporting online in the American Journal of Pathology, researchers from the Kimmel Cancer Center at Jefferson have implicated the loss of a stromal protein called caveolin-1 as a major new prognostic factor in patients with breast cancer, predicting early disease recurrence, metastasis and breast cancer patient survival.

New gene called DEAR1 may be a breast cancer diagnostic marker

In a research article published in this week's PLoS Medicine, Ann Killary (from the University of Texas M. D. Anderson Cancer Center) and colleagues describe a new gene called DEAR1 that is genetically altered by mutation and deletion in breast tumors, and that may provide a new breast cancer prognostic marker.

New early detection studies of lung cancer in non-smokers launched

Government and private sector cancer scientists today launched a research partnership to find biomarkers for lung cancer that develops in people who have never smoked. The research studies are designed to create a better understanding of the biology of lung cancer and to develop a test to detect early-stage lung cancer in lifetime nonsmokers.

Personalizing therapy the key strategy for survival in lung cancer

Cancer vaccines and targeted therapies are beginning to offer new treatment options following surgery for patients with early stages of lung cancer, experts said at the first European Multidisciplinary Conference in Thoracic Oncology (EMCTO) in Lugano, Switzerland (1-3 May 2009).

Urine proteome pattern may predict coronary artery disease

Proteome analysis, a screening requiring only a patient's urine specimen, shows promise as a reliable and noninvasive way to diagnose atherosclerosis and coronary artery disease in the future, according to research presented at the American Heart Association's Arteriosclerosis, Thrombosis and Vascular Biology Annual Conference 2009.

New findings on COX-2 inhibitor side effects

In searching for a simple way to identify individuals with smoking-related lung injury, scientists at Weill Cornell Medical College have stumbled upon a potential explanation for why the class of pain-relievers known as COX-2 inhibitors increases the risk of heart problems among users.

Research brings new hope, old problems with Alzheimer's disease biomarkers

Brain imaging and cognitive tests may be the gold standards for tracking Alzheimer disease progression, but clinical trials using these procedures are expensive, risky, and time-consuming, making the development of reliable go-betweens a pressing goal for AD researchers.

Newly discovered epidermal growth factor receptor active in human pancreatic cancers

Finally some promising news about pancreatic cancer, one of the most fatal cancers, due to the difficulties of early detection and the lack of effective therapies: Johns Hopkins University pathologist Akhilesh Pandey has identified an epidermal growth factor receptor aberrantly active in approximately a third of the 250 human pancreatic cancers studied.
