New Cellular Pathway Helps Protect Mitochondria During Stress, Study Shows

A specific branch of cells’ stress-response pathway called unfolded protein response (UPR) may help protect mitochondria, new research shows. This finding suggests that controlling this particular branch may help prevent or delay the defects in mitochondria that accumulate as we age and fuel so many human diseases. The study “…

Exercise Found to Raise Brain Energy Levels in Mice

A new study published in the journal Cell Metabolism revealed that exercise can energize brain cell function in animal models by increasing the levels of a specific mitochondrial enzyme. The finding may have important therapeutic implications for the treatment of age-related cognitive decline and neurodegenerative diseases. The study…
