Methods to assess the role of poly(ADP-ribose) polymerases in regulating mitochondrial oxidation

Abstract

The impact of poly(ADP-ribose) polymerase (PARP) enzymes on cellular NAD+ has been established for almost 30 years now and its sequel, the metabolic collapse of cells upon PARP overactivation is a nearly 20-year-old observation. However, in the last decade there was an enormous blooming in the understanding of the interplay between PARPs and mitochondria. Mitochondrial activity can be assessed by a comprehensive set of methods that we aim to introduce here.
