Drp1 inhibitor Mdivi-1 showed similar effects with OSE in DOX-exposed H9C2 cells. (A) Mdivi-1 decreased the elevated Drp1 expression and suppressed the enhanced autophagic activity in DOX-treated H9C2 cells, similarly like OSE. (B) Mdivi-1 reduced PINK1 accumulation on mitochondria and prevent Parkin translocation from cytosol to mitochondria in DOX-induced H9C2 cells. (C) Consistent with the effects of OSE, Mdivi-1 suppressed apoptotic activity in DOX-induced H9C2 cells. (D) Representative TUNEL staining images showing that Mdivi-1 suppressed the enhanced apoptosis in DOX-induced H9C2 cells, similarly like OSE.
