The mitochondria-targeted anti-oxidant MitoQ reduces aspects of mitochondrial fission in the 6-OHDA cell model of Parkinson's disease

► Sublethal 6-OHDA concentration of 50 μM, which is able to induce mitochondrial morphological alterations ► MitoQ abrogates 6-OHDA-induced mitochondrial fission. ► MitoQ reduces 6-OHDA-induced mitochondrial translocation of Drp.1 ► MitoQ reduces 6-OHDA-induced mitochondrial translocation of Bax.
