Pyrroloquinoline quinone (PQQ) producing Escherichia coli Nissle 1917 (EcN) alleviates age associated oxidative stress and hyperlipidemia, and improves mitochondrial function in ageing rats

摘要

Background: Ageing involves oxidative stress mediated by Reactive Oxygen Species (ROS) and mitochondrial dysfunction. The present work demonstrates the protective effect of PQQ producing EcN against rotenone induced mitochondrial oxidative stress and consequence of mitochondrial and cellular dysfunction in naturally ageing rat model. PQQ is a potent antioxidant molecule also known to stimulate mitochondrial biogenesis and function in mammals.
