Lycopene inhibits endothelial-to-mesenchymal transition of choroidal vascular endothelial cells in laser-induced mouse choroidal neovascularization.

ABSTRACT: Choroidal neovascularization (CNV), is a major cause of irreversible blindness among the elderly population in developed countries, which is resulted from subretinal fibrosis without effective therapeutic strategies. Endothelial-to-mesenchymal transition (EndMT) of choroidal vascular endothelial cells (CVECs) contributes to subretinal fibrosis. Lycopene (LYC), a non-pro-vitamin A carotenoid, plays an anti-fibrotic role. Herein, we explored the effect and mechanism of LYC on the EndMT of CVECs during CNV. Firstly, LYC inhibited EndMT in hypoxic human choroidal endothelial cells (HCVECs). Meanwhile, LYC inhibited proliferation, androgen receptor (AR) expression and nuclear localization in hypoxic HCVECs. Then LYC-inhibited AR promotes the activation of microphthalmia-associated transcription
