Description

The abstract identifies a novel protein complex at mitochondria-ER contact sites linked to vascular calcification but doesn’t explain the mechanistic pathway from this coupling to osteogenic gene expression. Understanding this mechanism is critical since vascular calcification contributes to neurodegeneration through cerebrovascular dysfunction.
