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.

New cell analysis platform developed - commercial partners sought

Sandia National Laboratories is seeking commercial partners to license or contribute to the continued development of a new lab-on-a-chip platform for high-throughput manipulation and interrogation of individual cells, one that enables quantitative analysis of cellular behaviors with unprecedented speed, resolution, sensitivity, and multiplexing.

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.

PEA-15 protein points to potential targeted approach for ovarian cancer

A protein known to inhibit the growth of ovarian cancer works in part by forcing cancer cells to eat themselves until they die, researchers at The University of Texas M. D. Anderson Cancer Center report in the Nov. 15 issue of Cancer Research .

Combination of carboplatin and paclitaxel with bevacizumab and cetuximab proves safe for lung cancer treatment

The four drug-combination of carboplatin and paclitaxel, with the targeted therapies bevacizumab (Avastin) and cetuximab (Erbitux), is safe and may improve survival for patients with advanced lung cancer, according to a cooperative group study led by The University of Texas M. D. Anderson Cancer Center.

Difluoromethylornithine may affect Barrett's esophagus

"While there was a suggestion that difluoromethylornithine (DFMO) may influence the extent of Barrett's dysplasia, this finding is very preliminary and further study of this agent in a larger number of patients is needed," said Frank A. Sinicrope, M.D., professor of medicine and oncology at the Mayo Clinic, Rochester, MN.
