The mitochondrial Cu transporter PiC2 (SLC25A3) is a target of MTF1 and contributes to the development of skeletal muscle .

The loading of copper (Cu) into cytochrome c oxidase (COX) in mitochondria is essential for energy production in cells. Extensive studies have been performed to characterize mitochondrial cuproenzymes that contribute to the metallation of COX, such as Sco1, Sco2, and Cox17. However, limited information is available on the upstream mechanism of Cu transport and delivery to mitochondria, especially through Cu-impermeable membranes, in mammalian cells.

Surface tension of model tissues during malignant transformation and epithelial-mesenchymal transition.

Epithelial-mesenchymal transition is associated with migration, invasion, and metastasis. The translation at the tissue scale of these changes has not yet been enlightened while being essential in the understanding of tumor progression. Thus, biophysical tools dedicated to measurements on model tumor systems are needed to reveal the impact of epithelial-mesenchymal transition at the collective cell scale.
