Cellular waste removal differs according to cell type, finds study

"Miniature shredders" are at work in each cell, disassembling and recycling cell components that are defective or no longer required. The exact structure of these shredders differs from cell type to cell type, a study by the University of Bonn now shows. For example, cancer cells have a special variant that can supply them particularly effectively with building blocks for their energy metabolism. The results were published online in advance. The final version has now been published in the journal Molecular & Cellular Proteomics.
