Effect of APE1 silencing on mitochondrial respiratory parameters. a Profiles of mitochondria bioenergetics measurements measured with Seahorse. Time and type of stressor administration are indicated. b The graph displays the relative average (±SD) basal and maximal respiration, as well as ATP production of HeLa clones silenced for APE1 expression (shRNA) and after re-expression of APE1 in all cells (APE1 WT) or only into the mitochondrial matrix (MTS-APE1). Data reported are the mean of four independent biological replicates. (*: p < 0.05; **: p < 0.01)
