This study identifies ATF4 as a master regulator of mitochondrial structural plasticity through a novel signaling axis, showing its role in stress-induced mitochondrial remodeling.

This study investigates age-related mitochondrial structural deficits in the kidney, finding that the MICOS complex is impaired, leading to increased oxidative stress and mitochondrial dysfunction.

This study uses 3D electron microscopy to analyze mitochondrial network changes in residual triple negative breast cancer after chemotherapy, revealing structural remodeling and lipid droplet interactions associated with chemoresistance.

This study investigates how MICOS disruption affects mitochondrial structure and function in neurons vulnerable to Alzheimer's disease, linking these changes to early mitochondrial dysfunction and neuronal vulnerability.

This study shows ATF4 coordinates transcriptomic and structural changes in aging muscle, linking it to mitochondrial dysfunction and suggesting the ISR pathway as a therapeutic target.

This paper provides a comprehensive protocol for quantifying cellular organelles using light microscopy and Fiji/ImageJ, enabling precise, high-throughput, and statistically comparable measurements across different samples.

This study investigates age-related changes in mitochondrial 3D structure in human skeletal muscle and shows that exercise can restore mitochondrial integrity through mitofusin 2.

This study investigates age-related changes in mitochondrial structure and function in the liver, identifying MICOS complex dysregulation as a contributor to metabolic and structural impairments.
