Abstract | We investigated the anti-EMT and antifibrotic effects of coenzyme Q0 (CoQ0), a quinone derivative from Antrodia camphorata, in TGF-β-stimulated adult retinal pigment epithelial 19 (ARPE-19) cells. Results showed that CoQ0 treatment reversed TGF-β-stimulated morphological changes from an epithelial to a fibroblastic phenotype in ARPE-19 cells. CoQ0 exhibited anti-EMT effects by impeding TGF-β-stimulated migration and invasion in ARPE-19 cells. Notably, CoQ0 triggered the epithelial marker E-cadherin and suppressed the mesenchymal marker N-cadherin expression in nonstimulated or TGF-β-stimulated ARPE-19 cells. Moreover, CoQ0 attenuated EMT and fibrotic Vimentin, MMP-9/-2, Slug, α-SMA, and VEGF expression in nonstimulated or TGF-β-stimulated ARPE-19 cells. Interestingly, CoQ0 inhibited TGF-β-induced intracellular ROS production by activating Nrf2 nuclear translocation and upregulating the HO-1, γ-GCLC, and NQO-1 enzymes in ARPE-19 cells. Moreover, Nrf2 silencing reversed TGF-β-induced ROS-mediated anti-EMT (E-cadherin/N-cadherin/Slug) and antifibrotic (α-SMA) effects in CoQ0-treated ARPE-19 cells. Therefore, CoQ0 could be utilized to treat age-related macular degeneration and proliferative vitreoretinopathy. |
