Intracellular glycine content and ROS were measured by liquid chromatography and MitoSOX, respectively, cell senescence was assessed by β-galactosidase staining, mitochondrial membrane potential was ...
Importantly, mitochondrial functions, as evaluated by the oxidative stress marker (MitoSOX) and mitochondrial membrane potential marker (JC-1 staining), were restored more completely by hTERT circRNA.
