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.

New scLS algorithm advances gene expression trajectory analysis

Single-cell RNA sequencing (scRNA-seq) is a method to measure gene expression of individual cells, allowing observation of various cellular processes, including cell differentiation, the cell cycle, and stimulus-response for each unique cell instead of averaging across millions of cells.

AI platform uncovers new molecular targets for Alzheimer's disease

Groundbreaking study published in Alzheimer's & Dementia reveals the crucial links between the NAD⁺-mitophagy axis and neurodegeneration.

AI tools map tumor architecture to predict treatment response

Spatial transcriptomics is a powerful tool to create a detailed map of not just how genes are expressed in a piece of tissue, but also where genetic activity takes place in different cells and locations within the tissue.

New dual-drug strategy blocks triple-negative breast cancer growth

Triple-negative breast cancer (TNBC) has a frustrating ability to adapt. Although this aggressive form of breast cancer can initially respond well to chemotherapy, cancer cells often find ways to survive, allowing the disease to return and become resistant to treatment.

New BioTAK score accurately identifies Takotsubo syndrome before catheterization

Takotsubo syndrome is an acute heart condition that primarily affects postmenopausal women and is often triggered by severe emotional or physical stress.

A personalized elimination diet changed the gut microbiome in people with migraine

In a 12-week randomized, sham-controlled trial of 98 adults with migraine, eliminating IgG-positive foods altered gut microbial composition and produced a greater reduction in serum zonulin than a sham elimination diet. The microbial changes were associated with previously reported reductions in CGRP and IL-6 and improvements in migraine and sleep, although the authors emphasized that these mechanistic links remain exploratory.

Your skin may offer clues about how many fruits and vegetables you eat

In an exploratory study of 137 Australian adults, skin yellowness measured by reflectance spectroscopy was associated with combined fruit and vegetable intake, fruit intake alone, total carotenoid intake, body fat percentage and skin color. The findings suggest skin measurements could provide an objective dietary biomarker, but the researchers caution that skin color, ethnicity and other individual characteristics may influence how the measurements are interpreted.

Rapid pathway for diagnosing heart attacks does not improve emergency discharge rates

A rapid pathway for diagnosing heart attacks in the emergency department (ED) was as safe as a slower pathway but neither reduced the length of time patients spent in the ED nor increased direct discharge from the ED.

Investigational anti-interleukin-6 monoclonal antibody achieves durable inflammatory biomarker reductions

The investigational anti-interleukin-6 (IL-6) monoclonal antibody pacibekitug produced sustained reductions in inflammation-related biomarkers through six months in patients with chronic kidney disease and elevated inflammatory risk associated with heart disease.

Pacibekitug safely reduces inflammatory biomarkers in kidney disease patients

The interleukin-6 (IL-6) antibody, pacibekitug, produced sustained reductions in inflammatory biomarkers in patients with chronic kidney disease at high inflammatory risk, according to results from the phase II TRANQUILITY trial presented in a Hot Line session today at ESC Congress 2026.

Compound PF-04457845 slows motor decline in ALS mouse models

Amyotrophic lateral sclerosis (ALS) is a severe neurological disease that destroys nerve cells responsible for muscle movement.

Blood-brain barrier-crossing blood pressure drugs linked to lower dementia risk

In a large Australian cohort of adults with hypertension, use of blood-brain barrier-crossing antihypertensive medications was associated with a lower risk of dementia and mortality than use of non-crossing drugs. The association was strongest for beta-blockers and angiotensin II receptor blockers, although the observational design means the findings cannot establish causality.

Researchers tested dozens of clues for long COVID. One finding stood out

A nationwide study of 218 people in the Faroe Islands examined clinical, neurological, and blood-based markers associated with persistent symptoms around six months after SARS-CoV-2 infection. Despite extensive testing, researchers found no convincing biomarker for long COVID, while a statistical association with lower INR remained within the normal clinical range and requires replication.

Multi-ancestry genetic score improves risk prediction for Alzheimer's disease

Late-onset Alzheimer disease (AD) is a progressive disorder characterized by cognitive decline and memory impairment, affecting an estimated 6.9 million people in the U.S.

Brain shrinkage biomarker may predict early-onset Alzheimer’s progression

In people diagnosed with early-onset Alzheimer's disease, a biomarker tool that detects shrinkage of the brain's gray matter may predict how quickly someone may progress from mild cognitive impairment (MCI) to dementia, according to a new study published August 26, 2026, in Neurology, an official journal of the American Academy of Neurology.

Brain atrophy on MRI could help predict Alzheimer’s progression

Mass General Brigham Neuroscience Institute researchers have found that a pattern of brain atrophy visible on MRI could help predict how quickly people with early-onset Alzheimer's disease progress from mild cognitive impairment to dementia.
