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.

Marker in blood may explain susceptibility to interstitial cystitis

A marker in the blood of both cats and humans that was identified in a recent study might signal both species' susceptibility for a painful bladder disorder called interstitial cystitis, a condition that is often difficult to diagnose.

Discovery of key molecular target in age-related macular degeneration

A team of researchers led by Dr. Jayakrishna Ambati at the University of Kentucky has discovered a biological marker for neovascular age-related macular degeneration (AMD), the leading cause of blindness in older adults.

Discovery of biomarker that predicts the outcome of certain breast cancers

Scientists have found a new biomarker that can predict the outcome of breast cancers that have spread to the lymph nodes, reveal findings published in the British Journal of Cancer today (Wednesday).

A new method for breast cancer biomarker discovery

Three researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech have developed and evaluated a new one-step bioanalytical approach that allows them to profile in detail complex cellular extracts of proteins. The method has allowed the scientists to look at how the levels of proteins change in breast cancer cells when they are treated with hormones or cancer drugs like tamoxifen.

Gene variation associated with resistance to chemotherapy drug in women with breast cancer

Researchers have found links between an individual's genetics and their response to treatment with chemotherapy. The findings, by researchers at the National Cancer Institute (NCI), part of the National Institutes of Health, and colleagues, show how a genetic variant, located in the SOD2 gene, may affect how a person responds to the chemotherapy drug cyclophosphamide. Cyclophosphamide is used in the treatment of breast and other cancers.

European project to define key stages of human ageing

Aston University in Birmingham, UK, is one of 27 partners involved in a EUR 12m project that is set to identify and establish biomarkers which recognise the key stages of human ageing.

Drug combo improves outcome for advanced non-small cell lung cancer

A new, international study found that the combination of two drugs delays disease progression for patients with advanced non-small cell lung cancer (NSCLC).

Blood pressure drug reverses liver damage

British scientists have discovered that blood-pressure drugs can reverse the effects of early-stage liver failure in some patients.

Research links intestinal inflammation with systemic chromosome damage

UCLA scientists have linked for the first time intestinal inflammation with systemic chromosome damage in mice, a finding that may lead to the early identification and treatment of human inflammatory disorders, some of which increase risk for several types of cancer.

Blood-pressure medicine shown to reverse the effects of early-stage liver failure

Newcastle University researchers analysed a small clinical trial of losartan, a drug normally prescribed for hypertension, on 14 patients in Spain, who had Hepatitis C.

New ultra-sensitive device detects viruses in minutes

Imagine being able to detect in just a few minutes whether someone is infected with a virus. This has now become a reality, thanks to a new ultra-sensitive detector that has been developed by Ostendum, a spin-off company of the University of Twente.

Discovery of biological markers that may indicate poor breast cancer prognosis

A team of researchers has found an association between breast cancer survival and two proteins that, when present in the blood in high levels, are indicators of inflammation.

QIAGEN launches novel product enabling non-invasive prenatal diagnostics and cancer detection

QIAGEN today announced the launch of a novel product for extraction of free circulating fragments of tumor- and fetal-derived nucleic acids as well as viral nucleic acids in human blood. Scientists consider these DNA and RNA fragments to have great potential for the highly sensitive and non-invasive diagnosis of a wide range of diseases, including congenital disorders, malignancies such as colon and lung cancer, and infections.

HER2/neu protein predicts development of invasive breast cancer in women with ductal carcinoma in situ

Women with ductal carcinoma in situ (DCIS) who exhibit an overexpression of the protein HER2/neu have a six-fold increase in risk of invasive breast cancer, according to a new study from the University of Pennsylvania School of Medicine.

MRI analysis software helps identify early Alzheimer’s disease

Analyzing MRI studies of the brain with software developed at the Martinos Center for Biomedical Imaging at Massachusetts General Hospital (MGH) may allow diagnosis of Alzheimer's disease and of mild cognitive impairment, a lesser form of dementia that precedes the development of Alzheimer's by several years.

Genetic signature predicts clinical outcomes in certain types of breast cancer

Vanderbilt-Ingram Cancer Center researchers have uncovered a gene signature that may help predict clinical outcomes in certain types of breast cancer.

Rapid test for prostate cancer

Researchers have developed the test by using light energy to measure the level of citrate in fluid samples from the prostate gland. The technique could provide the basis of a rapid means of detecting prostate cancer in the future. Almost a quarter of male cancers in the UK are diagnosed as prostate cancer and more than 10,000 men die from the disease each year.

Detecting diabetes with spit

Research promoting a painless new method for detecting diabetes, utilizing saliva, was revealed today at the American Association of Clinical Endocrinologists (AACE) 18th Annual Meeting & Clinical Congress.

Old diabetes drug Metformin teaches experts new tricks

Research from the Johns Hopkins Children's Center reveals that the drug most commonly used in type 2 diabetics who don't need insulin works on a much more basic level than once thought, treating persistently elevated blood sugar - the hallmark of type 2 diabetes - by regulating the genes that control its production.
