This study investigates the interaction between TMBIM5 and MICU1 in mitochondria, showing they regulate structure, calcium homeostasis, and apoptosis in Drosophila and human cells.

This study shows presenilin-1 regulates glucose metabolism and beta cell identity by controlling calcium homeostasis in pancreatic islets.

The paper develops two genetically encoded fluorescent iron reporter systems to monitor cellular iron status in live cells, showing cell-to-cell variation in response to iron treatments.

This study uses a tetracysteine tag to visualize VDAC1 dynamics in live cells, revealing its localization at ER-mitochondria contact sites and mitochondrial fission sites.
