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.
A new meta-analysis finds that a genetic biomarker test accurately predicts how men with high-risk prostate cancer will respond to treatment with radiation and hormone therapy.
Rutgers researchers have discovered that people with asthma and chronic obstructive pulmonary disease have a protein in their lungs that leaks a small molecule into their bloodstream that restricts their breathing instead of relaxing their airways.
Scientists have discovered a new link that could bring the scientific and medical community closer to understanding why glioblastoma, the most common malignant brain tumor, is deadlier in males than females.
At the beginning of neurodegenerative disease, the immune cells of the brain – the "microglia" – take up glucose, a sugar molecule, to a much greater extent than hitherto assumed.
Scientists from the Karolinska Institutet discovered certain metabolic mechanisms that SARS-CoV-2 employs to attack lung tissue.
Researchers have discovered that a particular protein can be used as a brain marker to indicate whether emotional memories can be changed or forgotten.
A new study reports that circulating tumor cells that exhibit the features of stem cells employ ICAM1 to enable the formation of CTC clusters.
Results of national research pinpointed potential biomarkers that could ultimately be employed for the diagnosis of progressive stages of liver disease.
Whether consuming cocoa, known to be packed with powerful antioxidants that protect our cells from damage, helps us age better, is a question scientists want to definitively answer.
A new study by researchers from the Gwangju Institute of Science and Technology in the Republic of Korea has revealed the mechanism of DNA repair by enzymes exonuclease III and polymerase I by utilizing single molecule fluorescence resonance energy transfer (smFRET)-enabled dynamic observation.
A biomarker that has proven to be a predictor for response to immunotherapies in melanoma patients also has clinical relevance for breast cancer patients, according to a new study published in Clinical Cancer Research, a journal of the American Association for Cancer Research.
Scientists discovered 22 lipids in the blood plasma of schizophrenia patients that were linked to slower symptom improvement over time.
Levels of a protein called neurofilament light chain (NfL) in the blood can identify those who might have neurodegenerative diseases such as Down's syndrome dementia, motor neuron disease (ALS) and frontotemporal dementia, when clinical symptoms are not definitive.
By putting a piece of soft, strain-sensing sheet on the skin may be able to detect skin disorders non-invasively and in real-time very soon.
A research team from Brazil and Portugal has identified a link between a microRNA (miRNA) and the presence of lead in an organism.
In this interview, AZoLifeSciences speaks to researchers from the National Cancer Institute about their latest research that investigated the genetic effects of Chernobyl radiation.
Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cancer cells in the body. It is a systemic treatment where drugs travel throughout the body and destroy cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumour.
Varying severity of COVID-19 symptoms in patients is reflected by levels of a chemical biomarker in their body which scientists say could be used to better manage treatments and other interventions, including vaccinations.
Scientists from Buck Institute have identified and are now developing an innovative, non-invasive biomarker test that could help quantify and track the performance of senolytics—a class of drugs that selectively destroy senescent cells.
Fish oil supplements are a billion-dollar industry built on a foundation of purported, but not proven, health benefits. Now, new research from a team led by a University of Georgia scientist indicates that taking fish oil only provides health benefits if you have the right genetic makeup.
