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.

Study looks at bisphenol A exposure in boys and prostate cancer later in life

Does exposure of baby boys -- in utero or in infancy -- to bisphenol A, a man-made chemical which mimics natural estrogens, predispose them to prostate cancer later in life?

Using HEPA filters may improve cardiovascular health

One day doctors may recommend using high efficiency particle air (HEPA) filters along with weight loss, smoking cessation, and exercise to improve cardiovascular health, according to researchers in Denmark.

Blood test detects early stage ovarian cancer with 99 percent accuracy

Researchers at Yale School of Medicine have developed a blood test with enough sensitivity and specificity to detect early stage ovarian cancer with 99 percent accuracy.

Seniors more likely to deny smoking when asked

More elderly adults are lighting up cigarettes and not reporting their nicotine habits to doctors and others, according to findings from one of the first studies to examine the accuracy of self-reported smoking habits by age, race and gender of adults 18 years and older by researchers at the Case Western Reserve University School of Dental Medicine and other university collaborators.

New understanding of cancer initiation

Researchers at the University of Nebraska Medical Center (UNMC) in Omaha have assisted in a significant discovery - the understanding of a common mechanism of cancer initiation - that could result in better cancer assessment, prevention and detection.

Scientists gain new understanding of gut bugs

Scientists have made a major step towards understanding precisely which bugs in the gut are involved in which processes in the body, by mapping the different species of bugs living in seven members of the same Chinese family.

Experimental biomarker test beats PSA in detecting prostate cancer

An experimental biomarker test developed by researchers at the University of Michigan more accurately detects prostate cancer than any other screening method currently in use, according to a study published in the February 1 issue of Cancer Research, a journal of the American Association for Cancer Research.

Eye blinks may help to identify children prenatally exposed to alcohol

While children with fetal alcohol syndrome (FAS) have identifiable craniofacial abnormalities, children with alcohol-related neurodevelopmental disorder (ARND) can have significant cognitive impairments without facial anomalies. An important new study has found that a deficit in eyeblink conditioning (EBC) can identify children with probable FAS, and may also serve to identify alcohol-exposed children who lack distinctive FAS features.

Link between microRNA expression patterns and poor outcomes for colon cancer

Preliminary research has found an association between certain microRNA expression patterns and poor survival and treatment outcomes for colon cancer, according to a study in the January 30 issue of JAMA: The Journal of the American Medical Association.

Medical Research Council and GSK to identify new therapeutic targets from genetic association studies

The Medical Research Council (MRC) and GlaxoSmithKline (GSK) have announced the creation of a jointly funded programme seeking to identify and validate genes associated with common human diseases. A key aim of the programme will be to translate these observations into new drug targets and biomarkers of disease.

New understanding of the link between heart disease and belly fat

By now, everyone knows that overweight people have a higher risk of heart attacks, strokes and other problems that arise from clogged, hardened arteries. And people who carry their extra weight around their waist - giving them a "beer belly" or an "apple" shape - have the highest risk of all.

Smallest particles from vehicle emissions may promote hardening of the arteries

Patients prone to heart disease may one day be told by physicians to avoid not only fatty foods and smoking but air pollution too.

Smart hydrogel particles: biomarker harvesting

The long and challenging effort to find blood-borne markers for cancer and other diseases may soon enter a new realm of success using a new nanoparticle that preferentially and rapidly removes small proteins and other molecules from blood while simultaneously protecting them from degradation.

Proteomic profiling shown more accurate than traditional biomarkers in identifying liver cancer

As the incidence of liver cancer continues to grow - fueled in large part, by rising rates of hepatitis C infections - so too does the need for tests to help diagnose the disease at an earlier stage.

The link between combined HRT use and the risk of lobular breast cancers

Postmenopausal women who take combined estrogen/progestin hormone-replacement therapy for three years or more face a fourfold increased risk of developing various forms of lobular breast cancer, according to new findings by researchers at Fred Hutchinson Cancer Research Center.

Metabolic syndrome in children

Metabolic syndrome in children represents a potentially serious threat to health in adulthood, yet many parents and caregivers do not have a clear idea of what metabolic syndrome is and why it is dangerous.

Lymphangioleiomyomatosis - potential clues into the treatment and diagnosis

Studies published in the Jan. 10 edition of the New England Journal of Medicine (NEJM) are providing clues into the treatment and diagnosis of LAM, or lymphangioleiomyomatosis, a progressive and deadly lung disease that affects women in their childbearing years.

Take care of your teeth and gums for a healthy heart

Each year, cardiovascular disease kills more Americans than cancer. And while most people are aware that lifestyle choices such as eating right, getting enough exercise and quitting smoking can help prevent cardiovascular disease, they may not know that by just brushing and flossing their teeth each day, they might also be avoiding this potentially lethal condition.

New biomarker for predicting liver cancer spread and survival discovered

New research has shown that a unique pattern of microRNAs, small RNA molecules that regulate gene activity, can accurately predict whether liver cancer will spread and whether liver cancer patients will have shorter or longer survival, even patients with early stage disease.
