Memory Biomarkers Confirm Aerobic Exercise Helps Cognitive Function in Older Adults

Until now, systemic biomarkers to measure exercise effects on brain function and that link to relevant metabolic responses were lacking. A study shows a memory biomarker, myokine Cathepsin B (CTSB), increased in older adults following a 26-week structured aerobic exercise training. The positive association between CTSB and cognition, and the substantial modulation of lipid metabolites implicated in dementia, support the beneficial effects of exercise training on brain function and brain health in asymptomatic individuals at risk for Alzheimer’s.

Cancer has ripple effect on distant tissues

A new study with zebrafish shows that a deadly form of skin cancer — melanoma — alters the metabolism of healthy tissues elsewhere in the body. The research from Washington University in St. Louis suggests that these other tissues could potentially be targeted to help treat cancer.“Tumors rely on a constant supply of nutrients to grow.

The Future of Precision Medicine

Precision medicine is a rapidly growing approach to health care that focuses on finding treatments and interventions that work for people based on their genetic makeup, rather than their symptoms.

Zeeshan Ahmed, director of the new Ahmed Lab at Rutgers Institute for Health, Health Care Policy and Aging Research, discusses the future of precision medicine, what needs to be done to successfully analyze the data necessary to develop individualized treatments and the role genetics play during the COVID-19 pandemic.

Exercise, Weight Loss May Induce Metabolism-related Changes to Molecules in Gut

New research finds that exercise causes changes to some of the body’s metabolites—small molecules the body produces during metabolism—and also triggers change in blood levels of unique “foreign” molecules not thought to stem from our own metabolism. These changes to the global metabolome—the entire group of metabolites found throughout the body in the blood, tissues or urine—may help scientists better understand the body’s response to exercise.

Blood Metabolite Levels May Help Identify Diabetic Kidney Disease

Noninvasive measurement may provide alternative to diagnostic kidney biopsy Charlottesville, Va. (June 24, 2019)—Metabolomics, the study of small molecules the body produces during metabolism (metabolites) may be a future key to identifying diabetes-related kidney disease. The finding will be presented…
