This study examines salivary GDF15 levels and their associations with biopsychosocial factors and stress reactivity in healthy adults.

The paper examines how physical activity affects mitochondrial function, ROS production, and calcium handling in skeletal muscle across the human lifespan, finding that aging does not reduce mitochondrial respiration but decreases calcium retention capacity.

The paper examines cf-mtDNA and GDF15 as potential biomarkers of mitochondrial health in aging, finding GDF15 correlates with age and diabetes while cf-mtDNA does not.

This study examines associations between mitochondrial markers, maternal distress, and pregnancy outcomes in two cohorts, finding correlations between GDF15 levels and gestational age and BMI.

This paper shows that GDF15 levels rise with psychosocial stress, depression, anxiety, and biological aging, and that saliva GDF15 has a distinct diurnal pattern and responds rapidly to acute stress.
