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.

Topographical brain maps are new frontier to catch early schizophrenia

John Csernansky wants to take your measurements. Not the circumference of your chest, waist and hips. No, this doctor wants to stretch a tape measure around your hippocampus, thalamus and prefrontal cortex.

Researchers profile genes in acutely ill idiopathic pulmonary fibrosis patients

The first findings from a one-of-a-kind, patient-driven effort to provide lung tissue for research might help doctors predict when patients with idiopathic pulmonary fibrosis (IPF) are becoming dangerously ill and also could point the way to interventions that could sustain them until life-saving transplants can be performed.

IU Simon Cancer Center researcher heads cancer study during Indiana Black Expo's health fair

A small drop of blood can provide researchers with countless clues into cancer. You can help researchers at the Indiana University Melvin and Bren Simon Cancer Center by donating a blood sample during the Indiana Black Expo's INShape Indiana Black & Minority Health Fair.

Poor sleep may be more dangerous for women than men

Women who get less than the recommended eight hours sleep a night are at higher risk of heart disease and heart-related problems than men with the same sleeping patterns.

Brain classification reveals the right cerebellum as the best biomarker of dyslexia

Parts of the right hemisphere of the brains of people with dyslexia have been shown to differ from those of normal readers. Researchers writing in the open access journal BMC Neuroscience used magnetic resonance imaging (MRI) to compare the two groups, and were able to associate the neurological differences found with different language difficulties within the dyslexic group.

Brain protein a possible biomarker for anorexia

Eating disorders such as anorexia and bulimia are often regarded as psychological or societal diseases, but new research suggests that they may have an underlying biological cause - according to a new study anorexic women have different levels of a brain protein to healthy women.

New biomarker predicts brain tumor's response to cediranib therapy

A report in Cancer Research, a journal of the American Association for Cancer Research, highlights a new biomarker that may be useful in identifying patients with recurrent glioblastoma, or brain tumors, who would respond better to anti-vascular endothelial growth factor therapy, specifically cediranib.

Search for prostate cancer biomarkers continues

Collaboration in prostate cancer translational research in Europe is not only vital to sustain the progress achieved in recent years but also to streamline current efforts between researchers and clinicians and avoid duplication or overlaps. This was amongst the goals of the two-day Prostate Cancer Translational Research in Europe (PCTRE) Meeting which opened today in Amsterdam, The Netherlands.

Biomarker in urine for appendicitis

Appendicitis is the most common childhood surgical emergency, but the diagnosis can be challenging, especially in children, often leading to either unnecessary surgery in children without appendicitis, or a ruptured appendix and serious complications when the condition is missed.

Cerebrospinal fluid shows Alzheimer's disease deterioration much earlier

It is possible to determine which patients run a high risk of developing Alzheimer's disease and the dementia associated with it, even in patients with minimal memory impairment. This has been shown by recent research at the Sahlgrenska Academy, University of Gothenburg, Sweden.

Researchers develop promising new breast cancer diagnostic marker

Indiana University School of Medicine researchers have developed a new breast cancer diagnostic marker that could enable physicians to more easily determine which patients have a less aggressive form of the disease that may not require chemotherapy treatment.

Discovery of candidate tumor suppressor gene and potential biomarker for colorectal cancer

Researchers have identified a new candidate tumor suppressor gene in colorectal cancer and examined its use as a potential biomarker in stool samples, according to a new study published online June 17 in the Journal of the National Cancer Institute.

New diagnostic technique detects possible Alzheimer's biomarker in blood

A new diagnostic technique which may greatly simplify the detection of Alzheimer's disease has been discovered by researchers at McGill University and the affiliated Lady Davis Institute for Medical Research at Montreal's Jewish General Hospital (JGH).

Discovery of genetic markers to help fight diabetes

Translational Genomics Research Institute (TGen) scientists have identified five genetic biomarkers that could help lead to improved treatments, with fewer side-effects, for patients with diabetes.

Simple blood test detects molecular marker of aging in humans

In 2004, researchers at the University of North Carolina at Chapel Hill Lineberger Comprehensive Cancer Center announced a crucial discovery in the understanding of cellular aging. They found that as cells and tissues age, the expression of a key protein, called p16INK4a, dramatically increases in most mammalian organs. Because p16INK4a is a tumor suppressor protein, cancer researchers are interested in its role in cellular aging and cancer prevention.

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.
