Dual-drug loaded nanoparticles (i.e., TL-ATRA NPs, TL = mitochondrial targeted lonidamine and ATRA = all-trans retinoic acid) not only efficiently deliver drugs to tumor site, but also suppress tumorigenesis and metastasis simultaneously. The underlying mechanism of the synergistic effect of mitochondrial targeted TL (triphenyl phosphonium (TPP+) conjugated lonidamine) and prolyl-isomerase PIN1 inhibitor ATRA is owing to the findings that ATRA disturbs the redox homeostasis, leading to the amplified sensitization of mitochondria to TL.
