This Tiny Cellular Gate Could Be the Key to Curing Cancer – And Regrowing Hair

After more than five decades of mystery, scientists have finally unveiled the detailed structure and function of a long-theorized molecular machine in our mitochondria — the mitochondrial pyruvate carrier. This microscopic gatekeeper controls how cells fuel themselves by transporting pyruvate, a key energy source, across mitochondrial membranes. Now visualized using cryo-electron microscopy, the carrier’s lock-like [...]
