Leaving its mark: How frailty impacts the blood

Researchers at OIST Graduate University developed a new method to diagnose frailty using metabolomics and identified key biomarkers in the blood. The study found that 22 blood metabolites correlate with frailty, cognitive impairment, and hypomobility, offering potential for early diagnosis and treatment.

Can't sleep? Prebiotics could help

Researchers found that prebiotic dietary fiber can influence gut bacteria and produce bioactive molecules that may modulate stress physiology and sleep. The study used mass spectrometry to analyze rats' fecal samples and found that those on the prebiotic diet had a different metabolome, including higher levels of fatty acids and sugars.

Natural 'breakdown' of chemicals may guard against lung damage in 9/11 first responders

A new study suggests that metabolites produced by the body's breakdown of toxins may protect against obstructive airway disease in 9/11 first responders. Researchers identified specific compounds, including protein-building amino acids and omega-3 fatty acids, which are found in diets rich in fish and olive oil.

University of Alberta researchers discover new biomarker for rare autoimmune disease

University of Alberta researchers have identified a unique biological marker that can predict the course of myasthenia gravis and develop personalized treatment plans. The biomarker, composed of 12 metabolites exclusive to patients with myasthenia gravis, enables early diagnosis and more effective management of the disease.

These sharks use unique molecules to glow green

Researchers have identified a previously unknown family of small-molecule metabolites responsible for the bright green color in sharks' skin, which may also aid in identifying other sharks and fighting microbial infections. The discovery opens new questions about the potential functions of biofluorescence in shark biology.

Study sheds new light on the harms of air pollution

Researchers found 69 metabolites changed significantly when air pollution fluctuated during the Beijing Olympics, affecting systems like cardiovascular and nervous systems. The study identified two major metabolic signatures, including lipids and dipeptides, which were involved in oxidative stress, inflammation, and other processes.

Tracking small things in cells

Researchers created SCOTfluors, a class of small fluorophores that can be attached to common metabolites and emit light in the visible to near-infrared range. This allows for the observation of metabolite trafficking in living cells without destroying them.

What can worms tell us about human aging?

Researchers have developed a community-agreed model of worm metabolism, which has been re-optimised for relevance to metabolic changes during ageing. The model predicts that Oxaloacetate production becomes limiting in aged worms, potentially leading to extended lifespan by up to 20%.

An elegant mechanism

Mitochondrial researchers at the University of Freiburg discovered a critical role for the metabolite channel porin/VDAC in protein import into mitochondria. The study shows that porin/VDAC stimulates carrier protein import independently of its channel activity, forming an 'elegant mechanism' to regulate mitochondrial function.
