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.

Potential biomarker diagnostic test for pre-eclampsia

Collaborators at Cottage Health System and University of California, Santa Barbara (UCSB) have identified biomarkers that may yield a revolutionary diagnostic test for pre-eclampsia, a complex and potentially life-threatening hypertensive condition affecting 5% of pregnancies worldwide.

Epigenetic alteration associated with increased risk of breast cancer

Monozygotic twins have the same genome, that is, the same DNA molecule in both siblings. Despite being genetically identical, both twins may have different diseases at different times. This phenomenon is called "twin discordance". But how can people who have the same genetic sequence present different pathologies and at different ages? The explanation partly lies in the fact that the chemical signals added in the DNA to "switch off" or "switch on" genes can be different. These signals are known as epigenetic marks.

Study identifies new risk factors for bladder cancer

Low depressive symptoms and a longer telomere length are compelling factors that contribute to a prolonged life for bladder cancer patients according to researchers at The University of Texas MD Anderson Cancer Center.

Stat5 protein could serve as biomarker to help guide prostate cancer treatment

Men who had high levels of the activated Stat5 protein in their prostate cancer after a radical prostatectomy were more likely to have a recurrence or die from the disease compared to men who had little to no presence of the growth protein, according to a recent study published in Human Pathology by Jefferson's Kimmel Cancer Center researchers.

Sustained attention deficits in bipolar patients, relatives

Patients with bipolar disorder and their first-degree relatives exhibit deficits in sustained attention, study results show.

VeriStrat identifies NSCLC patients likely to respond to erlotinib

A study, published in the November 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology, showed the plasma test VeriStrat can predict response but not survival benefit from erlotinib. The study was conducted on a subset of patients enrolled in the NCIC Clinical Trials Group, BR.21 phase III trial of erlotinib versus placebo in previously treated advanced non-small cell lung cancer patients.

Fit elderly NSCLC patients should be considered for salvage targeted therapy

Until there are more validated biomarkers to direct treatment decisions, many physicians use patient age to decide what therapy to give their patients. Literature data report that older patients often go undertreated because of concerns for limited tolerance to toxic therapies.

Critical Diagnostics signs agreements with four new European distributors

Critical Diagnostics, a U.S.-based biomarker company focused on cardiovascular diseases, today announced that it has signed agreements with four new European distributors in Germany, Spain, France and Turkey.

Neurotensin as an indicator for poor health outcomes in women

The satiety hormone neurotensin may provide a novel biomarker for assessing risk for diabetes, cardiovascular disease, and breast cancer among women, report researchers.

Antioxidant defense reduced in schizophrenia, bipolar disorder

Results from a Tunisian study suggest that the antioxidant defense system is altered in patients with schizophrenia and bipolar disorder.

New research lists cell stiffness as possible biomarker for metastatic ovarian cancer

New Georgia Tech research shows that cell stiffness could be a valuable clue for doctors as they search for and treat cancerous cells before they're able to spread. The findings, which are published in the journal PLoS One, found that highly metastatic ovarian cancer cells are several times softer than less metastatic ovarian cancer cells.

Fibulin-3 protein may help identify mesothelioma in early stages

Researchers at NYU School of Medicine have discovered the protein product of a little-known gene may one day prove useful in identifying and monitoring the development of mesothelioma in early stages, when aggressive treatment can have an impact on the progression of disease and patient prognosis.

UCSF project to explore mystery behind advanced prostate cancer

Many men survive prostate cancer, but thousands of others -- whose cancer spreads -- inevitably develop resistance to even the most promising treatments, leaving them with few medical options and a dwindling span of life.

Salivary-biomarker approach can identify individuals at future risk of PTSD, depression

Each year, more than a million Americans are at-risk of developing serious mental health problems after experiencing a terrifying event or serious physical injury. Once manifested, these psychiatric illnesses, such as post-traumatic stress disorder and depression, can be extremely crippling and difficult to treat and are a leading cause of disability in civilian, military and minority populations.

Mayo researchers discover new therapy for patients with neuromyelitis optica

Mayo Clinic researchers have identified a new therapy for patients with neuromyelitis optica that appears to stop inflammation of the eye nerves and spinal cord. NMO is a debilitating central nervous system disorder that is often misdiagnosed as multiple sclerosis (MS).

Study compares gene expression levels in two key hippocampal regions affected by Alzheimer's

Researchers from the Computational Intelligence Group based at the Universidad Politécnica de Madrid's Facultad de Informática have used machine learning and data mining techniques to compare gene expresssion levels in Alzheimer's disease (AD) patients in two key regions of the hippocampus: the dentate gyrus, where the disease appears to have little or no effect, and the entorhinal cortex, where Alzheimer's disease produces major neuronal damage.
