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.

Heart damage during middle age linked to greater dementia risk in later life

People with signs of damage to their heart during middle age are more likely to develop dementia in later life, according to a new study led by UCL (University College London) researchers.

Oxidative stress linked to repetitive behaviors in mice

Abnormal repetitive behaviors in mice are strongly linked to multiple biomarkers of oxidative stress, which occurs when antioxidants cannot counteract the effects of harmful molecules in the body, according to a study published November 5, 2025, in the open-access journal PLOS One by Kendall Coden and Dr. Joseph Garner of Stanford University, U.S.

How gut microbes shape sleep: New review reveals microbiome clues to insomnia and apnea

A new Brain Medicine review maps how gut microbes influence sleep disorders, from insomnia and sleep apnea to circadian disruption, via bile acids, neurotransmitters, and immune pathways. The findings highlight gut-driven targets for improving sleep quality through diet, probiotics, and microbiome modulation.

UCLA experts call for individualized heart monitoring in breast cancer survivors

As breast cancer survival rates continue to climb - 4.3 million women in the U.S. are currently living with a history of the disease and in the next 10 years that number is expected to rise by another million - heart health has become an increasingly important part of survivorship care.

Stress hormones may silence crucial neuronal genes through specific RNA molecules

What if the brain's response to stress could be read not in fleeting neurotransmitter bursts, but in the quieting of genes deep inside chromatin? Researchers at the University of Alabama at Birmingham have now shown that stress hormones may silence crucial neuronal genes through an unexpected class of RNA molecules that operate not by encoding proteins, but by reshaping the genome's architecture.

How walnuts combat inflammation and oxidative stress in the body

This review in Food Science & Nutrition synthesizes evidence showing that walnuts (Juglans regia L.) exert potent antioxidant, anti-inflammatory, apoptosis-regulatory, and immunomodulatory effects through bioactive compounds influencing mitochondrial, cytokine, and redox pathways.

Combined analysis of three blood tests enhances heart attack risk prediction

A combined analysis of blood tests to measure three biomarkers linked to higher risk of cardiovascular disease-lipoprotein a (Lp(a)), remnant cholesterol and high-sensitivity C-reactive protein (hsCRP)-may help identify high-risk individuals earlier and guide more personalized prevention strategies, according to a preliminary study to be presented at the American Heart Association's Scientific Sessions 2025.

Disrupted brainstem-parahippocampal connectivity identified as a biomarker for delirium

Delirium, commonly observed in critically ill patients following intracerebral hemorrhage (ICH), is an acute neuropsychiatric disorder characterized by disturbances in attention, consciousness, and cognition.

Genetic insights into vestibular system damage from ototoxic drugs

The vestibular system is responsible for the sense of balance in the inner ear. Prolonged use of toxic substances, such as certain antibiotics or anticancer drugs, can damage the hair cells that form part of this system, leading to alterations in balance and other motor skills.

Study reveals how TDP-43 causes neuronal overactivity in ALS and FTD

A new Northwestern University study using patient nervous tissue and lab-grown human neurons has uncovered how a key disease protein, TDP-43, drives overactive nerve cells in the neurodegenerative diseases amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD).

Advances in diagnosis and management of systemic light chain amyloidosis

Systemic light chain (AL) amyloidosis is a rare and life-threatening disorder characterized by the deposition of misfolded immunoglobulin light chains as insoluble amyloid fibrils in various tissues and organs, leading to progressive structural and functional impairment.
