General description

MitoPQ (MitoParaquat) is a mitochondria-targeted redox cycler composed of the lipophilic triphenylphosphonium (TP) cation-conjugated paraquat that induces mitochondria superoxide production via redox cycling at the complex I flavin site. MitoPQ increases mitochondria superoxide production at a ~1000-fold higher efficacy than untargeted paraquat using either live cells (fold of change of MitoSox fluorescence = 1.4/1 μM & 3.2/5 μM MitoPQ vs 1.2/5 mM PQ; C2C12 myoblasts) or isolated mitochondria (fold of increase of H2O2 efflux = 4.6/1 μM MitoPQ vs 2.6/1 mM PQ; rat heart mitochondria). MitoPQ is a valuable tool for conducting cellular and in vivo investigations into the role of mitochondrial superoxide generation in redox biology. Additionally, it can be utilized as a catalyst or co-stressor to replicate metabolic and neurodegenerative disease traits in experimental models.

Application

MitoPQ has been used to enhance mitochondrial reactive oxygen species (mitoROS) production in T-cell culture and investigate its influence over T-cell differentiation.

Developmental synapse pruning refines burgeoning connectomes. The basic mechanisms of mitochondrial reactive oxygen species (ROS) production suggest they select inactive synapses for pruning: whether they do so is unknown. To begin to unravel whether mitochondrial ROS regulate pruning, we made

Mitochondrial oxidative stress, mitochondrial dysfunction, or both have been implicated in insulin resistance. However, disentangling the individual roles of these processes in insulin resistance has been difficult because they often occur in tandem, and tools that selectively increase oxidant production

Mitochondrial reactive oxygen species (ROS) production is a tightly regulated redox signal that transmits information from the organelle to the cell. Other mitochondrial signals, such as ATP, are sensed by enzymes, including the key metabolic sensor and regulator, AMP-activated protein
