On the cover: Electron micrograph depicting mitochondrial dynamic changes and mitophagy in diabetic tubulopathy. The top row showing elongated mitochondria with organized cristae in normal tubular cells (left), the organelles underwent fragmentation and cristae disruption during diabetic injury (middle), whereas mitochondrial fusion-fission process was partly restored following administration of Dglucarate, a MIOX inhibitor (right). Lower images showing the morphology of autophagosome, mitophagosome and autolysosome in tubular cells of D-glucarate treated diabetic mice. Ming Zhan, Irtaza M. Usman, and Yashpal S.
