Now, we have the first picture of how that process works, thanks to the structure determined and colleagues. They find that a single SecY complex from Methanococcus jannaschii forms an hourglass-shaped pore with a basal plug that probably swings out...

متن کاملMdm2 pulls the plug on glycolysis
C ancer cells have long been known to have higher rates of glycolysis than normal cells, a phenomenon named the Warburg effect after its discoverer Otto Warburg (1). Enhanced glycolysis is thought to allow cancer cells to survive the hypoxic conditions they experience in the center of solid tumors. But Mikawa et al. reveal how damaged cells switch off glycolysis as they enter senescence and sho...
