675-Miro2-Driven Mitochondrial Transfer
This research article from Nature Cancer explores how malignant cells reprogram their environment by physically transferring mitochondria to nearby fibroblasts. Using advanced imaging and genetic tracing, the authors demonstrate that this exchange occurs through tunneling nanotubes, thin bridges that connect the cells. Once they receive these foreign organelles, the fibroblasts undergo a metabolic shift and transform into cancer-associated fibroblasts (CAFs), which then actively support tumor growth. The study identifies the protein MIRO2 as the essential motor for this transport, noting that…
